Yeah i know everyone is probably sick of these threads, but you reckon 5 - 7 psi would be safe on a stock engine ?

Engine was rebuilt a few year ago and besides some leaks runs great.

should be ok... i think!

If you have all the other supporting mods such as the bigger fuel pump and injectors etc plus a decent tune it should be ok, but to be on the safe side i would run it with 4-5psi to start with and see how it goes!!

Depending on compression ratio, i would think 6-7 would be ok....
Provided a good tune is available. If you want more you could always go the cheap alternative a double the head gasket.... to lower the comp.

Yeah thats the easy stuff :). The main thing im worried about is the ECU.

ATM i am running an auto radiator in my car and as you know, they have oil lines for the auto boxes. Would it be efficient enough to be used as an oil cooler for the turbo ?

I learned a few things when me and my bro supercharged his VN and attempted to turbo his R31 so i think we have it sussed out now.

I really wouldnt be going anymore than 5psi.

I dont see why the internal oil cooler wouldn't be good enough, but for the cost put a large capacity oil cooler on the front aswell....

Mate personally i would just buy a 4G63T engine for 3kish roughly and then just drop that in, more power and more reliable in the long run as the motor is built for forced induction, the first gen motor wont handle the boost for too long on stock internals i imagine and will need to have forged internals installed regardless in the long run which may set you back more than the newer engine would have cost to buy and install imho!!

But then again your time and money so good luck regardless!!

What ecu are you planning to use btw?

I assume you have the 4 banger? Why dont you set up a suck through carby setup? Even a blow through?somthing different... Will eliminate the need for the aftermarket ecu, a good distrbuter place shoud be able to adjust the timing advance in the dizzy.... just a thought for the cheap side. And it works.

The oil cooler'll do the job well, just make sure there's no crap in there before hooking the oil lines up

Theoretically, 5-7psi should be fine on stock internals, as long as it's reasonable condition. The compression ratio's low anyhow. The low boost will also eliminate much lag too, so it'll be a good streeter. The standard ECU will have a heart attack though. lol

4G63T doesn't bolt right in, and you lose torque down low, but have more power available higher, so it'll be slower off boost, but quicker on.

Nah i know but it has been done before so it can be done again lol

I assume he would need custom engine mounts maybe a few other things but turbocharging the current engine will come with just as many headaches, but either way it will be nuts, a first gen dosing with the fmic popping out sounds hot to me :D

good luck with it all gemini :thumbsup:

Nah im pretty happy with the low down torque i just want something more at top.

So it looks like ill be sourcing some parts. :D ECU, im not sure. I want something that isnt to expensive but isnt ****.

Sigma turbo didnt come out with EFI hey ? What about a turbo starion 2.6 would the ECU from that work on the Magna ( not sure if they came in EFI ) ?

Like i said i dont wanna spend tons but i dont want it to be crappy.

Thanks. I might be getting some good moneys soon. If i get this new job that is :)

If i was going to put another engine in i would rather just import a complete v3000 ( v6 1st gen ) from NZ and transfer everything over to mine. I have been thinking about this for a while but it would so suck if nothing matches lol

They use the narrower Sigma body, so the bits across the middle don't match, however there is enough commonaility for parts. I looked into it a little while back, and there's bugger all information.

Damn looks like i wont be doing any turboing on this car unless I open it up. Car pings its nuts off when the weather starts getting hot.

O well. Might just leave it and just get some suspension work done and re gas my air con.

havent seen a tuboed 1st gen round here for ages or a serious n/a in a while, im going down the n/a path myself. just hoping the stock ecu will handle it

this is how much and how to do

moonga s TR motor can be adapted to the 2.6 engine first gen just takes cash

dont know what happened to the cars turboed

Check my profile mate give you idea what you need but it costs alot of money and time.

Stock internals are good for about 12psi, I've driven 5000km on 10psi on a safe tune doing some engine work like lowering compression and valve springs will help then if you want to blow 5k get some some nice pistons and rods

The stock fuel system will not sustain anything so upgrading that is a must because if you lean out trouble occurs.

200fwhp is safe for the stock gearbox, I blew the stock clutch pretty fast so upgrading that is a must and iv put in new CV's

Basic things to start off ruffly

Manifold $450
Turbo $350min + second hand tdo5 14g min or t28 ( iv got tdo4 to small )
Dump $250
Exhuast $1000
Intercooler $400
Plumbing $800 odd

Injectors $500
FPR $250
Fuel Pump $250
Surge Tank $120
ECU fuel/ignition type $1000

CV'S $400
Clutch $1000
Shocks $400
Springs $400
Rubber $400

Labour 1k min

There is $8570

+ all the minor little problems which occur that drive you insane

HP fiqures 200fwhp if all done properly

exceed that internal work is required.

RPW did one for someone and charged him large amounts for 202fwhp and it took like 9months

doubling HP from stock form is a good target, but since they start of with low HP so don't expect 250fwhp straight away

I could talk all day about it because there are so many problems and issues, personally I wouldnt bother doing it

The only serious N/A platform that I can think of going not so long ago was Mad Lante`s, to day it's still a great car

Been in his car myself and it clocks to 100 in about 7 seconds. He used an after market rising rate FPR to get around the ECU limitations.

Which is the same path that I'll be taking very sooooon. :)

look into why your motor is pinging

dont regass the air con ... remove it
the air con takes power away from the engine

you can do a simple turbo up to 6-8 psi before having to do major motor work

it will be important to have all the suspension done properly
especially sedans rear

they can be sloppy on curves

spoke with Mad Lante on cam spec and fuel issues he had and overcome va pms before he was banned i guess it helped me with what direction i went, i cant recall if hes using stock valve springs or not we are looking to use some ford springs possably on my project head due to the cam spec i dont think the stock ones will be good enough basicly springs / fpr / plenum & chrismass holding the project back.

what a legend go the turbo on the 1st gens

wait, what does N/A mean?

wait, what does N/A mean?

Naturally aspirated. Means non turbo :)

ohh. is it really worth putting turbo on these cars? reading from before its gunna cost like 8.5k and thats a sh#tload for a first gen. Would love to see it done but WAY too costly for me:D

$8000? wow, you can get a turbo galant engine for maybe 1-2 grand. which more or less fit straight into the first gens

I actually built Madlante's motor, he has pretty much stock internals, used older adjustable rockers however I still feed there was issues with the cam as getting it all adjusted was a nightmare.

Head was a M8 from memory and it was then ported, these were pretty big damn holes, not much holding the guides in lol

He had issues with either a good bottom end but no top end or if he got the top end right, was a pig down low. Cam profile can cause this.

We used the lower compression pistons so if he does decide to give it some breathing help one day he can simply bolt it all on.

he used stock springs.

i had an agressive cam on mine, and didn't upgrade the springs. it was on the to do list, but the motor didn't like revving high anyways.

Also - those of you with manual boxes... if your smart enough and do your research, you can swap over the transmission for the same box, but different ratios. you'll trade off topspeed of the car for faster acceleration. catch me on msn or something if you want to know more.
