Ok, so now I'm just stumped. I have a choice of all these different motors for my TF and I know that the auto gearbox & ECU will have to be changed for some of them. So which one should I go with (I don't know the engine codes sorry):

Stock 3.0ltr
GTO 3.0ltr twin turbo quad cam (but I'm guessing a half-cut GTO would be best)
3.5ltr with or without turbo
3.8ltr with or without turbo
Possibly a V8 (nothing is impossible)

Those who have read my threads know it annoys me that my wifes Mazda 6 beats me off the mark and at high range but now I have skylines & commodores in the mix and it's bugging the bejesus out of me. It's time to get serious. Which one?

Of course it's for track *cough
:yeahthat:

Want to have a go at getting one of those jap limos from mitsubishi over and seeing if anything will bolt up to the v8 in it?
The twin turbo gto engine might be the wrong orientation.

If you can fit it go a V8 =) but otherwise the 3.0 ltr would go nicely

These cars are so cheap that I think you're better off selling yours and buying a 3.5 and forget the hassles of engine conversions

Go 3.8, its good to be different.

lol... if you're wanting to turn your car in to a race car you will have to convert it to manual. Otherwise a 3.5 conversion with the autobox would be okayish... :P

Whaaaaaaaaaaat?? No way! What's the fun in just getting something else with it already attached? More fun modifying, "doing it up" & whatever else than getting something I have to do nothing to :P

Well I didn't until you said that. Now I want to.

I'm thinking 3.8ltr on LPG, drop the fuel tank to lower weight (I got enough to make up for it) & possibly turbo it but I'm keeping the auto. May need to upgrade it but having an auto for a change is good.

. . . . . it annoys me that my wifes Mazda 6 beats me off the mark and at high range . . . .
. . . . . skylines & commodores . . . .

If you really want to outperform the Mazda 6, skylines and commodores (?) I would not start with a TF as a basis. lol

It's actually one of the lightest models you can get :P

TH 3.5 would be the next best.

Buy the cheapest TH 3.5L Sports in Manual with who cares how many K's for 1-3 grand as long as the body's straight and the paint is good.
Drop the 6G75 3.8l inside it as well as an LSD and gearbox rebuild.
Get more aggressive cams (angry sticks) and a tune for 98RON.

Or... buy an R33 Skyline and get power from that lol

Oh yeah, get the 380 brakes while you're there or face certain death.

Source a Mitsubishi 8A80 4.5L V8, always wanted to see it in a Magna and its only 20kg heavier then the 3.5 V6.

I know that the car that had the V8 fitted in it (mitsubishi dignity) also had an option for a 6G74 so the V8 might fit a magna?

Man where would you even begin to try and source one lol

NOW we're talking :D

That's half the fun mate.

Why do people give up so easily when they boast cars are their passion? If there's one out there, all it takes is patience and a hell of a lot of research & digging around. When you finally get what you're after, your brain has a party long after you fall asleep lol. It's much more fun making the car the way YOU want it to be, not making sure it looks & acts like everyone elses. For example, it's apparently near impossible to put gas struts on the boot instead of those damn snapping tension rods. Guess what, I did it. Wasn't that hard really, just "patience and a hell of a lot of research & digging around" ;)

Sorry, I just hate giving up too easily. And that's my rant for today

8A80 may be avail on special order from a Jap import wrecker, i think they were only sold in small numbers though.
what about the Lexus 4.5 V8 , they are everywhere.

I saw a jab ebay/yahoo site or something that had about 15 v8 mitsus for sale? Whole cars though, and only about 1/4 of them were listed as available for export.
3L GTO engine in a 2nd gen thread: http://www.aussiemagna.com/forums/showthread.php?t=85085

what about the Lexus 4.5 V8 , they are everywhere.

How much modification would I need to do to drive shaft, engine etc?

i guess it would be a total custom job , but at least the lexus motor is available everywhere and cheap.

no matter what you squeeze in there ( and anything other than a 6G will be a squeeze ) it will be a lot of work.

Hmmmm, I am really liking the Lexus idea & ya right, they are everywhere quite cheap. Been warned by a mate though that while they're cheap to buy, parts are a different story. All part of the fun I guess lol

lexus v8s si\ound ok, the hyundai v8 sounds good too, and I think that was based off the joint mits/hyundai 4.5 v8. Wonder if it will bolt up to a magna trans with custom mounts and exhaust?

That's got a beautiful tune behind it hey

Is this thread serious or just a joke?
If you want more performance you have the wrong car plain and simple. Ask Ego how much it costs to go fat and how long it took to get the car like that.
If you are just looking for an upgrade for your current motor go fo r a 3.5L there are plenty around or even a 3.8L if you can get one. You could even get a Super Charger for the 3.5L but then you would be looking at an easy 10K with the motor and install.

Last time I checked it was serious. I'm not concerned with time or how much it costs. I got time and I can save.

its cheaper , if it were me to get something powerful as a hoon machine and keep the magna as a daily driver. my mate bought a Lexus SC400 for $2000 , just buying the engine off that car alone is about $1500.

All depends what you actually want in your car, if you are realistic about your expectations, and how fast you really want to go.

In my opinion, for an everyday reliable streeter somewhere between 14-15 seconds over the quarter is actually fast (Have a look how many stock road cars get under 14 sec quarters? Phase 3 GT Falcons, most HSV commodores, non-gtr Skylines, garden variety WRX's etc. all run over 14 seconds, mostly anyway?).

Then there is perception:
An HSV/Skyline is faster than a Magna, no-one really raises an eyebrow, but
when it's a Magna being faster it becomes a big deal in everyone else's eyes.

Ego (and the like) will tell you the same thing, hearing or seeing people's amazement is the fun part!


IMO that's the best thing about a decent Magna, no-one expects it, including the Police who won't target you as much if you drive sensibly as well.

If you take a 3.5 lt manual magna and spend $350 on 380 cams, $350 on cam install, $450 on a tune, $450 on a cat back exhaust, and get some good grippy tyres you will surprise the bejesus out of every wannabe on the road, Mazda 6's and the like will be no trouble. You will have a reliable sub 15 second car, with decent fuel economy, as long as you don't abuse it!

However if you want to run under 14 seconds, you're probably in for a bit more money, but at least you can build on the above.

brett my car is stock apart from exhaust and its into the 14's and i cant wait to slap a 3.8 into mine and see what it does

I think you would be better off getting a VRX

SEE? Not that hard to comprehend that I am serious about this. And yeah, the whole people's amazement, that's part of the goal.

I'm NOT going out to buy a different car & I'm NOT going out to make sure it complies with everyone else's form of "normality". I'm doing this for me, only me and to hell with anyone who thinks it's easier to give up than work on it. So, as a footnote:

If you plan on saying what other car should be bought or how it's a ridiculous idea, no need. Making yourself "sound" important isn't the same as actually stating what can be done to help achieve what people are asking about. If I wanted a different car, I'd go to a different forum.

By the way, thanks Brett, good ideas :)

Glad you are asking questions about what might suit you best for increasing power for your Magna.

Im in progress now with an engine conversion and i cant wait to get it finished.

50% of the fun im having is actually doing this myself , the other 50% will be when i shift through gears on the open road once it finished.

Whatever you do to increase the power, make sure you do as much as you can to reduce the weight as well :)

My AWD Magna with me & stereo & fuel weighs over 1700kg at the Tip's weigh bridge.
A FWD Manual TJ Magna should be ~ 150kg less, hopefully the TF is even lighter still, but see what you can do to save weight - wheels, seats, spare wheel? etc. :)

There's 2c from me.

What would be a wiser option for an engine replacement into a manual TH - a 3.5ltr from a TJ Ralliart or a 3.8ltr from a 380? (with consideration to better performance, approx costs & difficulty)

3.8L.

Ralliart Engines are rare as hell and go for much more than the 380 engine - the gain is simply not worth the price.

Might as well just put 380 cams in the 3.5l and get a dyno tune.

Whatever you do to increase the power, make sure you do as much as you can to reduce the weight as well :)
Yeah, been thinking of dropping the fuel tank & running on LPG only, but LPG may be cheaper, just doesn't last as long. Love to take out the seats, but sadly my wife and boy think they should be able to come along as well. Families can be so inconsiderate at times.

Apparently, from what I've read, the TF is the lightest model or one of them anyway.

I have a low k one for sale at the moment in the FS section.

No one's told you to change your car in the last 8 posts and not since you already emphasised you weren't changing your car.

So who are you talking to exactly?

He is saying he has an engine for sale!
No is bagging you out about wanting a FastMagna, it is just the simple fact they often people say they wanna make their car fast by doing a big engine conversion or rebuild ect and then they go off and get prices and you never hear of the project again. I will applaud you if you can do it, look at stackys car for an example if you wanna go quick in a magna. Like many have suggested your best option is to upgrade your current engine with the 3.5L or 3.8L 6G motor. Id get that in first and get it all running well and then maybe look at dropping weight or even going FI.

BINGO :P
lmao

Get a 6G75. Preferably try to get the manual box out of 380 too lest they might have changed a few things including the ratios which could be more suitable. You'll need to work on your suspension and wheels/tyres since the 6G75 has 0 trouble lighting up the front wheels in a heavy-ass 380. Tyres with a very low sidewalls will actually lose the accelerative traction sooner. As somebody already said get a 380 brake conversion too and get slotted rotors while you are at it to get best braking without a worry that they'll crack like the drilled ones do.

So I'm guessing drop the racing profiles than. I already have enough fun keeping the front on the ground & steering on high acceleration so I get your point there.

What would I need to do to suspension?

I'm going with slotted rotors, just not changing over till engine is done & will upgrade to 380 callipers as you and a few others who know what they're talking about have advised.

As far as the manual goes, would that just be for the sake of going manual? If I need to change boxes, I'd rather stick with auto & bolt on a cooler, but I've decided that in the end it will be turbo & with TiMi saying in room that you can go turbocharged combined with supercharged, I've been looking into that & I'm thinking manual might be better not just for torque but also for controlled braking. Might be a failed plan, but hey, can never fail without trying.

Thanks heaps

You want to dual charge your magna turbo/super?

Manual is the best power mod you can do, just have a look at quarter mile times of good manual drivers and the auto Magnas.

Just remember the more power you put through the more stress is placed on your transmission.

You want to dual charge your magna turbo/super?.
*Nods enthusiastically

Yeah, OK, I'll go manual. First auto car I've had and was rather enjoying the laziness of it lol.

That just leaves what to do with suspension. It has lowered King springs, new struts but won't touch rear shocks till I'm told if there is anything that needs to be done to suspension in case I'm wasting time & money if it all needs to get changed.

drag tyres have a tall sidewall that flexes to aid with traction (actual drag cars, not high profile street tyres) and are good in a straight line. Lower profile tyres flex less, but give more stable grip in cornering.
Auto box uses power to run the hydraulic pump in it, weighs more, and is one more electrical thing to sort out if your doing big mods and need aftermarket ecu's

man i read this post - unless u got 10k to spend i wouldn't worry about it....... magna is not meant to be a quick car. I have a verada as a daily and an R33 (skyline) for weekends and mainly track use.

Stock skyline would rip a 3.5L verada to shreds and with 3k in the motor it is running high 11s......

after sinking 4k in your magna it will be as quick (if u are lucky) as an stock r33 and most are slightly modded so u will be slower anyway, though pill to swallow lol plus there is no chance you will keep up through corners.

Your call though, your cash not mine lol

OMG I almost had the cash for a 3.8ltr set up, just to find out that GM in America have a small block fwd V8! Oh I GOT to have one of them now *drools an ocean*

Have to keep saving now lol

I can vouch for the ease that power can be obtained from Imports/ Factory forced induction vehicles. 5k spent on an XR6 Turbo will have you running 12 second quarters, or have a cracker handling 32 skyline.

It all depends on your end goal, do you want to spend your time at the strip? Or would you like the ability to give a Silvia a scare through the twisties?

I say, a set of coil overs, strut brace, good tyres would be the way to go first. Then focus on making it go and stop. My personal preference would be a massaged 6G75 with cams, lightweight flywheel, full intake and exhaust and port/polish work.

I agree, the handling, grip & starting traction is the first part to be done, just being so close to getting the first motor, may as well keep going with the new idea. Will take a crapload of work, but the main reasons are:
- To see the faces in the mirror as I leave a commodore or similar at the lights. Not just beat them, but actually pulling away before they can understand wtf happened
- Because I've been told by several people it's a waste of money. Funny really, the nicest cars are the ones that others consider are a waste of money to start with. When they see the finished project they tend to stf up
- Why the hell not :D

If you're dreaming big:

Mistubishi 8A80 V8 (as mentioned above) was
- 4.5L (4498 cc) DOHC GDI, 206kW (as per Japanese limitation)
- found in the Mitsubishi Dignity and Mitsubishi Proudia (co-manufactured with Hyundai and also marketed as the Hyundai Centennial or Equus)
- both of which are FWD
- Proudia was also available with the 6G74
- though both Proudia and Dignity are around 95mm wider (if that means anything)
- Hyundai converted the 8A80 to multi-point injection as premium unleaded was not widely available in Korea at the time

8A80 is probably hard to find as all get out, would require some major engineering but could possibly be a good starting point. No particular opinions here, just raw info.

And yes, I just pulled that all from Wikipedia, so it's not like I know what I'm talking about :D

Sod that, if you are going to the trouble of fitting a mitsu V8, just do it with a toyota/lexus unit instead

I'd go one step further and say, if you're going to go to all that trouble, you may aswell fit a 2jz Supra engine and do a big single turbo conversion.

So a 1.5jz engine then...1jz single turbo setup with 2jz bottom end ;)

I agree with soleit, Having a car that was plainly not designed to go fast is the fun of it. Dad has a 1987 VW Caravelle Kombi with a Subaru H6 from an SVX in it, and that thing is amazing to drive. Best feeling when your still looking into the passenger window of a commodore halfway to the next set of lights.
I will be following this so closely, should be an interesting thread hope it all comes together into something special.
(sorry i have nothing information wise to add to your thread)

Hey, no need to apologise, I like it :D Your fathers Kombi sounds pretty decent and yeah, ya right, looking int he mirror at the driver who is trying to figure out what just happened is brilliant lol

Sod that, if you are going to the trouble of fitting a mitsu V8, just do it with a toyota/lexus unit instead

Dumb question. What's the difference? Is the mitsu V8 underpowered?

I will take some happy snaps and a few vids and post it in non mitsu members rides when i get a chance. Mainly because i know my 'rada isn't good enough yet to go in there haha

Cool :D Let me know when you do mate :)

Have you tried finding a mitsu v8? Toyota v8s are ten a penny

Pardon my ignorance, is the Toyota V8 fwd? I know the mitsu one is as well as a few chev engines, but can't find anything saying Toyota V8s are

No, they aren't. Nothing money can't fix though.

If you want to throw your money away:

- Diamante 30M Heads (DOHC MIVEC Intake+Exhaust)
- Overbore 10:1 (Forged Pistons) 6G74 (3.6L)
- Spool rods
- Wild headwork (Ported, polished, shaved)
- Custom ECU + Tuning to 8500rpm
- ARP head studs
- ACL bearings throughout
- Balanced and blueprinted
- Walbro 255 Fuel pump
- Subaru "Pink" injectors

Just hope you got deep pockets, doubt you'll get change out of $10k.

**** it'd be fun though.

Compared to a v8 conversion, slightly
boring

All that weight of a V8 where a six once was? Effects on handling? Compared to power advantages?

Weigh up the costs of dumping and eight in there, then take that budget and pour it into a six. See which works out better.

This sounds like it would produce a six that would eat an eight - in the same car.

I must agree, I proper re-build on the 6 will still cost you a fortune, and will still be more than fast enough. You would also have less time without the car.
