Hey every1,

Did a search but didnt come to a thread with all the info in one place so hopefully this will work. Just wondering what can be/has been done in terms of creating a tough naturally aspirated 2nd gen magna.

Ill start, I have a '93 TR with a 2.5" redback exhaust system, lukey extractors, no resinators, K&N panel filter, custom cold air intake and has been dyno tuned. Goes well for an auto but like most people...I want more without turboing.

I have heard about some people using a Falcon XF throttle body...what does this do?

Thanks and looking forward to the responses

Do you have a V6?

If so, DOHC 24v 6G72 conversion is the only way to go.

4cyl, you don't have much in the way of making it a tough n/a car, sorry.

His profile says its a 4 banger. Really there isn't a lot that can be done short of force feeding the donk, but there are some hot 2.6's out there. They are pretty full on though. Dedicated gas set ups, mad cams, porting and polishing, quad throttles, new internals + N20. The best bang for buck is the nitrous, but the downside is it can only be used off street... Mate if youre keen, and you have deep enough pockets, a crazy n/a 2.6 would be great, and definitely pretty rare!

What numbers u pulling at the wheels so far? I'm assuming you know considering it's dyno tuned.

by dyno tuned do you mean an on dyno timing adjustment??

With the astron everybody goes turbo as it's relatively easy, unless you have excess amounts of money n/a on a 8valve engine isn't going to reap much in the way of rewards.

I with a full rebuild to run on the street with a semi aggresive cam, porting chip etc you'd still only make about 130hp at the wheels and have a 1/4 mile of around 15.3 or so. lol ive only managed 15.6 in my DOHC with 168hpatw but i had no clutch and didnt launch hard at all (60ft = 2.45, i've been under that with the old motor).

While to turbo would probably be cheaper and you'd have about 170hpatw.

Just common sense.

These cars can definately handle a bit more than 170hpatw's we'll see there should be a twin turbo 6g72 in a verada soonish.

Peace out

kill billy i will have to disagree with you... i am on the way to pulling some decent power out of my 2.6 and for street driving it pisses on just about everything. i can smoke v8's easily... its only after 2nd gear when their power becomes apparent and most street racing doesnt go past that anyway. not that i condone street racing but who are we kidding thats wot every1 wants the power for.

i am the one running an xf throttle body because it is 67mm compared to the standard 59mm. i gained 6hp atw from this mod. however i will get more once i make a different plenum chamber because the stock one is too restrictive.

15 sec 1/4 miles are very quick for any 4 cyl car... especially a magna. if you want n/a power im with ya. for starters if you whack a turbo on u have to get the car relicensed as a turbo which means brake upgrades etc... and a massive intercooler hangin out the front for the cops to see... and then you will only run 14's. which is slow for a turbo car.

there are various issues with building an astron turbo magna as im sure monga will agree... 170hp was achieved by him and correct me if im wrong with stock internals which could not handle the boost for very long... and the best that i know of achieved by a proffesionally built engine running a turbo was 140hp atw.

if you want some advice from someone who ahs already done the hard work pm me because posting will just attract many critics.

good luck with it mate my first suggestion is manual conversion happy to go through it step by step. the power increase is remarkable...

You'll always get better economy and easier motoring in a V6 over a nutted astron, I'm witht he 6 crowd here, sure its fun to say you have a wild astron but really, when it comes time to LEGAL racing which DOES use more than first gear you will get eaten by astras.

give it a couple of weeks and hopefully i will have a time slip to show everyone what an astron can really do n/a... new extractors and tune by next thursday so should be down for a race wednesday 15th november at quit motorplex...
also it is so much funnier racing ppl ... beating them... then when they say what have you done to your v6?... i open the bonnet revealing....
what u see in my avatar

by the way i hope to have the 100hp nitro by christmas so i will be looking for a 13sec pass with that sucker. not even a new six with nitro makes that very often

hmmm... any one know how to get drivers for sony erricson k608i to hook up to computer...??? i have a vid of me racing a turbo skyline and beating it to 3/4 track before his turbo spooled up enough to overtake me....

The sony ericsson web site should have drivers.

Cant wait to see what else you do to your astron its gonna be killa :D I have actually been looking at those Paxton superchargers but they are to damn expensive. I have a sc14 sitting in my shed but its to damn bulky to put it anywhere lol

Id be happy with a 14 second pass with a SC.

yeah s/c would produce better results but as u said too bulky to put anywhere. have u thought about taking out ur air box and mounting it above the g/box... that was my idea at the time... and drive it off water pump pulley?

ooooo i dont know about that! Will that little pulley be ok driving something extra ? I was thinking about it though.

As for the airbox, if i ever do sc the car, that stupid thing is GONE as i will be bolting the TB infront of the SC.

The paxton might fit where the airbox is but the sc14, i doubt it.

Nah mate jumping on other cars off the line isn't so exciting, top end is where the fun is. Thats why the latter model magna's are loved on here, they have their problems off the line but are faster than v8's up top. An example is how i was faster than blackbeards twin turbo to 100km/h but i know which would be more fun to drive. It's also like the riced up astra that all of a sudden took off at the lights and cause he had so much of a start he wouldn't of realised how much faster my car was, i made up the 2 car lengths to 70... 60 limit therefore stopped.

13's is very optimistical of 100hp nos but these cars are lightish. Good driving as a skyline should always have a fwd of comparible weight with lower power to weight ratio for the whole track. Show us the footage.

It's ridiculous how much faster my car was than a 5L v8 from 100 on.

A properly rebuilt astron engine would easily handle 220hpatw, big displacement, but i cant tell whether youre saying that or the max a workshop would pull out of a stock internal turbo 4g64 was 140hp, which should run 15flat-14's. It's good to make your n/a astron a lil faster just dont expect it to be fast.

Hell keen to get back to the drags. Not starting arguments either.

Peace out

im saying a workshop got 170atw out of stock internals with a turbo and only 140 with a rebuilt engine (different people)... not saying it cant be done but im yet to see a purpose built magna astron turbo make decent power...

oh yeah alos i agree 100% top end is where the fun is hence my new custom extractors. car is only making power to 5500rpm yet i have a 7500rpm cam. should be fun to see what it makes with the exhaust all tuned up...
i dont think 13sec is too optimistic as the car will run 15 sec with extractors, and 100hp is a lot extra for my car (not quite double) should be making 235hp atw with it...

i also have further mods i could do to get lower 1/4 times such as underdrive pulleys, aluminium flywheel, actually fit the twin 47mm t/b and plenum i made(may compromise top end though which is the direction im going with the car)... but as someone else said ypu can go as far as u want to as long as your pockets are deep enough... and unfortunately mine arent.

at the end of the day i think i have done well to make it what it is... when i bought the car it did 0-100 in 18sec. with its carby auto ****. now it does it in just under 9...

i know i could just buy another car that already does quicker than that but where is the fun... its about having something unique that not many ppl have done... as im sure all magna enthusiasts would agree

my next project could be my old triton ute fitting magna injection and a turbo to that as i have seen many many examples of sigma engines (same as triton but diff to magna) making over 300hp atw... now that would def turn heads!!!

thats it in the back ground

magnatism, im with ya all the way mate. its so much better burning up a v6 or v8 and seeing the looks on their faces when you tell them you have a 4cyl. ive done it to a commie and i loved it hahah. the xf throttle body sounds like a decent idea, how much? and how do you hook it up? much difficulty?

will the XF throttle body work on a 6G72?

Thanks for the replies guys, keep them coming.
Definately heading down Magnatisms path with my mods and the XF throttle body sounds like a great idea!

im saying a workshop got 170atw out of stock internals with a turbo and only 140 with a rebuilt engine (different people)... not saying it cant be done but im yet to see a purpose built magna astron turbo make decent power...

there was a 1st gen with astron in one of the bigger aussie mag's with 300kwatw i believe... might've been 300hp.

Oh and 100hp nos doesn't equal +100hp at the wheels but i'm interested to see what you gain with the nos.

would like to see that article let me know if ya can find it

also the bigger t/b will make any car better as long as it can be tuned.

0-100 in 9 seconds, and u reckon u'll do a 13sec ET? :bowrofl: i think u'll struggle to get under 16.

but by all means, get the time sheet and prove me wrong.

0-100 in 9 seconds, and u reckon u'll do a 13sec ET? :bowrofl: i think u'll struggle to get under 16.

but by all means, get the time sheet and prove me wrong.

maybe i was unclear 0-100 in under 9 is n/a i will then add 100hp nitro which i believe will run a 13 sec pass or at least close to it.

oh yeah and for those who asked about the xf t/b here's what i did... may take some pics when i get the car back from the xhaust place

also its not as simple as just changing the t/b either. you do need an ecu to retune it... but here are the steps if ya wan2 give it a go:
1). get xf 67mm t/b from wreckers (duh!)
2).take off the accelerator cable pulley and turn it around 180 deg to make it pull the other way. i think you have to cut bits of the aluminium throttle stop brackets off.
3). make the mounting holes in the t/b slightly bigger so the screw holes will line up with ur plenum.
4). fit falcon t/b and mark with texta (while opening butterfly) how much of ur plenum u need to grind out
5). Grind out plenum to make air inlet bigger.
6). buy 2 rubber plugs to block off the crank case ventilation holes in the falcon t/b.
7). fit plenum to car and cut a piece of flat bar (30mm x 250mm long by 3mm or so) and mount it to plenum where the accelerator cable would normally mount and then drill and tap holes to bolt your accelerator cable to the flat bar as the accelerator cable needs to be moved.
8). join the 2 coolant hoses from the original idle speed motor together ie bypassing it.
9). get car retuned!!!
nearly forgot have to cut the plug off ur tps and splice in the wires from the falcon one... will tell u the colours when i get the car back

16.2 Doesnt smoke V8's unless they're old ****ters or not being driven properly...

If I can only just beat a gen 3 to 110, and you "smoke" v8's then that must be one hell of a 2.6...because my PB is 14.8 which I've probably gotten down to about 14.6 now, but 14.8 is the official so let's use that, and you're running 16.2

Sorry dude...it's time to wake up to reality here.

PB is 14.8 which I've probably gotten down to about 14.6 now

how do you launch kb, i'm thinking with the DOHC its powerband is quite high so it need alot of revs off the line and alot of clutch riding, and a fair share of wheelspin off the line, that's how mine seems to get going the best.

Also do you go right to the thoretical redline (lol as we can't tell where it is) through your gears??

You're on msn but busy... therefore soz for semi offtopicness.

I think a 4cyl manual might have me to 35, the DOHC is about 50kg heavier (guess) than my old SOHC which is in turn probably about 30kg heavier than the 4g64

I sorta slip it as I launch...but I've never had a nice open place to practise it, so I never get better at it. In the traffic light gp, I usually just get it to roll a bit before I plant it...means I have a much higher chance at losing to cars that have a lot more low end torque, but in the end it's only traffic light gp, it means FA lol

I push 1st to about 65, just before it hits the limiter at about 70km/h or 7200rpm. 2nd I run basically to the limiter too, just before, change at about 110-115km/h, and just sit in 3rd till the end. 3rd doesnt even get a chance to wind out by the time I cross the line, 3rd really only picks up serious pace at about 150km/h and i crossed at 153.22km/h.

But yeah, my launches suck **** lol

A 4cyl manual will most prob get me off the line because of the fact that I can't plant it straight out. I demonstrated to my mate the other day that if I dump it at around 2000rpm it wheelspins. So yeah, but that could also be due to maybe needing some suspension work :) There's always room for improvement.

I'll carry this on PM if you want mate.

magnitism, if u can back all this up then sweet power to u

but as far as im concerned the astron 2 is a peice of crap in terms of a potential "powerhouse", i dont care how big the TB is or how flowed the extractors are, at the end of the day it still wouldnt even touch a 2.4L lancer in STOCK form

im sure u may have suprised a few v8's to 60, but u cant say u beat them, most cars with any kind of power cant use it in 1st gear its just not realistic,

personally the only reason id spend money an atmo 4cyl is for rev and response, not for power ( im actually still hoping to do this asap just trying to find the right car)

u said that its not till 2nd gear that the power becomes apparent and the other cars pull away from u when dragging, well in all honesty, 1st gear is all about getting traction not about power, its not even a drag its who has faster reaction time and who's tyres stick 1st.

im not having a dig at u for modding ur car, tis good to see ur putting alot of effort into it, im saying perhaps u slightly..........WAY to optimistic on ur 1/4 mile times after mods

we all want to belive that our cars are better than they really are, but at the end of the day an NA 4 atron 2 thats in a reasonably heavy car is never gonna suprise anyone, especially with the new 4's that are coming out that really pack a punch ( honda apparently has an integra coming out with 170kw's NA at the fly:O)

if ur going for power out of ur engine especially NA, sorry but u will just never be satisfied, however if ur after response and a revvy engone then u may be on rightr track, though its not something the astron is known for at all.


i ges u can look at it like this, all the v6 boys will be thinknig ur wasting ur time on an NA 4, all the 4cyl turbo boys wqill think ALL of us are wasting our time, and the v8 boys think Everyone stated is wasting their time lol , i ges it just comes down to what u want out of ur car, but sorry bud it will never be "quick"

however all of this is ONLY MY OPPINION

Meh ran a 13.8 (best time of about 6 runs, most were low 14's and 14 flats) with a 100 shot of NOS (I think it was a 100 shot) and this was on a V6 that has about 145hpatw N/A. I like the idea of a second gen weapon, but don't get too optimistic or you will be sorely dissapointed.

if you own a 4banger, i wouldnt really bother doing it up in N/A, turbo it.
The bottom end in these engines handle alot, due to it relaiting to the sigma turbo, and other relaited G45B, and 4g54 turbo engines, the potential is under estimated for these engines, i am currently runnin mine with a turbo setup and its running 15psi, no hp figures or drag times, i have video of it while driving.

P.S, its only runnig the small turbo on it, i am just waiting on a few things before the bigger injectors go in and the turbo.

OMG dood can u put that on megaupload so i can save it to my comp pleaseeeeeee

Just a question, if you put cams into a SOHC would that bring the performance anywhere close to that of the DOHC 6G72?

Cheers

I agree with a turbo the 4G54 can be a monster. I used to have a video of a van with a 4G54T running about a 12 sec 1/4 mile.

With cams on the SOHC, probably not be as smooth, because the exhaust ports on the SOHC are tiny compared to the DOHC ones. DOHC ones are like a big block V8 rounded rectangle size, SOHC's are small circles. There'll be a big difference in the amount of exhaust getting out.

I would like to see a SOHC modded of it's dial though.

Really are you so sure about that? Maybe ask Ashneel how his sisters Lancer ran against my car before you so quickly dismiss the Astrons..........

Don't forget that it greatly depends on the driver too.

I doubt a normal lancer would beat a stock 2.6 astron would it?

Im speechless :shock:

Im speechless :shock:

thats on the initial tune isn't it, god that spooling turbo sounds porn, exhaust sounds meaty too, ****ing awesome work mate.
But nothing beats my exhaust seriously it's bull****. :P

Absolutely awesome mate! Well done! :D
Very jealous

not the initial tune, No

turbo is to small for the mods i have, not really that cool to drive yet. and the exhaust clip is only going to 4000rpm, i will bring the car on a Perth meet sometime.

That's nice VIP. I've been away for a while so you may have gone over this while I was away, from your profile it seems like you are just running on the stock internals at the 15 psi, is that correct?

What people seem to underestimate about the astron is that it isn't a 'power' engine but a torquey one. Due to it having a longer stroke than bore they make their torque pretty low down so off the line they are pretty damn quick.

The trouble with them though is that due to only having 2 valves per cylinder they are pretty asthmatic. By turboing these things you get that massive torque increase midrange/topend, so you have the long stroke taking care of the early/mid and turbo keeping the mid and top happy.

Also I remember about some guys stateside attempting to knock up a DOHC for the Astron (http://www.aussiemagna.com/forums/showthread.php?t=11209). They are/were designing it for the Starion, so if it even exists it should just bolt up onto the magnas. I say that as I know a few Starion/Sigma/Scorpion owners have converted their carby Astron1's to MPI Astron2's using Magna heads.

yes my internals are standard, but the compression has been lowered, im have PAUTER RODS WISECO PISTONS coming in from america, these have been tested at 600 wheel HP.

All i will need is a good excuse to take the engine out.

haha yeh mate im sure it took the skyline 300m to spool the turbo... :gtfo:

I never saw that comment haha..It sure must be very impressive to beat a turbo car that's not spooled up. Kinda like beating a parked V8 :bowrofl:

im sorry but what tyhe **** would u idiots know about my car. why would i bother making **** up. how bout you actually offer someone some real advice instead of just dissing people and telling them what cant be done. if ya cant do that maybe just shut your mouths.

do you actually remember what this thread was about??
josh was asking how to build an n/a astron motor not how to be told not how to do this and have the piss taken

because of the inaccuracy of your statement they are having a go at you, 14s rwd car will have a 16s fwd car over every aspect of the 1/4, i'm betting you had a much better start.

ie a turbo would be spooling from about .5secs down the quarter.

I'm also against posts purely to have a dig...

Harden up a bit too eh, yeah you've done well with your car and people aren't going to always respect the work you've put in it. I think you'll find most of us don't drive/mod/buy our cars based on what other people think. Therefore you shouldnt worry.

To sum there's the easy way to wind some power from the astron but if going n/a it'll be more pricey but it wont be much more money to make it something good (14s) as opposed to something ok (15s). ie lumpy cam, custom intake dual t/b's etc...

... Yea!

Dude you spun a lot of crap when you replied to me. You expect us to believe that a 16.2 1/4 mile is "smoking V8's"???

Or the fact that you beat a skyline before it spooled?

Both are huge achievements...you should pat yourself on the back.

The work, however, is commendable. The way you make it up more than it should be...isn't


Perhaps you should THINK before you POST.

I think im might comment on this thread considering a built my own turbo magna from scratch and discovering all the rubbish that came with it.

Magnitisium all your statements require evidence otherwise you are dreaming FWD magnas are very hard to move in a straight line RPWS TWIN TURBO can only do 13.2 in street trim this car has had thousands spent on it. 13.2 is nothing special with stock commodores SS running high 13's straight out of the factory.

I will comment on the astrons engine being strong as I killed mine while I had it on stock internals, also these engines will never have a RPM band like a CA18 so don't expect 6500rpm shifts.

When racing 2nd gear is all that matters, thats a joke mate I will take you for a spin in my GTR second gear is over in 3 seconds what kind of race is that?

2.6 ASTRON TURBO's would have being awesome 10 years ago against a VN SS but you will require 260odd HP if you want to run a 6litre SS after 100kmph

Who is working on your car magnatisum?

kill billy i will have to disagree with you... i am on the way to pulling some decent power out of my 2.6 and for street driving it pisses on just about everything. i can smoke v8's easily... its only after 2nd gear when their power becomes apparent and most street racing doesnt go past that anyway. not that i condone street racing but who are we kidding thats wot every1 wants the power for.

i am the one running an xf throttle body because it is 67mm compared to the standard 59mm. i gained 6hp atw from this mod. however i will get more once i make a different plenum chamber because the stock one is too restrictive.

15 sec 1/4 miles are very quick for any 4 cyl car... especially a magna. if you want n/a power im with ya. for starters if you whack a turbo on u have to get the car relicensed as a turbo which means brake upgrades etc... and a massive intercooler hangin out the front for the cops to see... and then you will only run 14's. which is slow for a turbo car.

there are various issues with building an astron turbo magna as im sure monga will agree... 170hp was achieved by him and correct me if im wrong with stock internals which could not handle the boost for very long... and the best that i know of achieved by a proffesionally built engine running a turbo was 140hp atw.

if you want some advice from someone who ahs already done the hard work pm me because posting will just attract many critics.

good luck with it mate my first suggestion is manual conversion happy to go through it step by step. the power increase is remarkable...

These v8's your smokeing must be old dinosors or f***ed.
