My turbo build. no pics...yet.

[PocaFocus]

Ok so I'll most likely start a new thread when I start getting parts in.

Ok so for those of you who don't know I have a 91 Talon TSI AWD.

Ok I plan on making some decent numbers with this car. So here we go.

Comments and suggestions are greatly appreciated.

Ok so current mods are: Port & polish head, ARP head studs, ported exhaust manifold, full 3" exhaust, dump tube, manual boost controller, short shifter, boost gauge, and fog lights.

I already have a full ground force suspension waiting for me to pick up. Along with a Megan stage three block, with balanced and lightened crankshafts, Ross 8:5:1 pistons, and Crower connecting rods.


After I get it all put together and running I plan to add little stuff and add more expensive stuff when needed. So tell me if this is out of order or if you think I missed something.

intake piping and filter - ram horn exhaust manifold - turbo timer - FMIC - A/F and EGT gauge - engine management (possibly AEM box) - 850cc injectors - Walboro 255 fuel pump - new turbo - rebuilt clutch -

Anything I am missing, or any steps I need to include?

sorry I am a noob :nopity:

Looks like you have a damn good start with the bottom end. Why do you have a dump tube on an internally gated turbo? Does it have an o2 dump on it?





intake piping and filter - sidewinder exhaust manifold - turbo timer - FMIC - A/F and EGT gauge - engine management (possibly AEM box) - 650cc injectors - fuel pump - new turbo - lightweight flywheel and clutch -


You don't need a "sidewinder" manifold, just get something equal length that is going to flow bad ass like a ram horn.

You don't need a turbo timer. Regardless of how cheap some people call me, prove to me that it saves the life of a turbo and I will be a believer. There are way too many turbo cars running around that don't have them. I think if it really did something useful cars would come from the factory with them. RICE!!!! It basically comes down to what you NEED. You don't NEED rice under your hood. Are you reading this Shea and Steven?

Walbro fuel pump is the only way to go with a drop in pump. Its dirt cheap and works. 650cc injectors are a little small IMO If you are going to get any type of ems dsmlink being the best option IMO, get 850's or bigger. You can tune them down to run like stock. There is no need to buy injectors to suit your needs right this second when you may want to upgrade in the future.

You don't need a lightweight flywheel. Again this is the ultimate in ricer technology. I'm not going to say it doesn't work. They are pretty nice on all motor cars. Your car needs a stock flywheel IMO unless you are running a twin disk. Have you ever heard/read any horror stories of people shattering flywheels? This is something that scares the absolute crap out of me because I have seen pictures of flywheels that went through hoods and firewalls. Being "cheap" may actually be safe in this situation.

Just get a streetable clutch made from triangle clutch. There is no need to be baller when their clutches work just fine. I put down 340tq with their clutch with no problems. :thumbsup:



If someone from the LCM area wants to call me out for being cheap, spit it out. Or else STFU and stop talking shit :thumbsup:

no idea that's how the car came.

what size pump do you suggest?

There is no need to buy injectors to suit your needs right this second when you may want to upgrade in the future.

at what point will I need to upgrade?

and when will I need to get an actual tune?

[Matticus]

IMO do all your drivetrain stuff first and start piecing together a bad ass turbo set up. Once thats done throw everything together and get it tuned. As for now K.I.S.S. :thumbsup:

walbro 255

[jeremys14]

saving a couple of pounds on a flywheel doesn't make much sense to me either. unless going twin disc, just get a badass clutch. what bov do you have? unless your planning on high boost any one should do. turbo timers are a waste imo. upgrade your radiator, and fan. that should be a good start

[Matticus]

His stock bov is bad ass!

Being that the car is so old, Jeremy is correct. A new radiator and some fans wouldn't be a bad investment at all.

[PocaFocus]

what bov do you have?

for now it's the turbo system is still stock.

First I have to pull the motor out of the car, put the ported head on the new block with buil bottom end. Then put it in the car and get it running.


unless your planning on high boost any one should do.

I am thinking about running somewhere around 20psi... What do you think is a good psi for the compression?

upgrade your radiator, and fan.

A new oem radiator and fan should be sufficient correct?

[jeremys14]

fork out the extra bucks and get at least a copper koyo and an electric fan.

[Matticus]

Make sure not to bitch out! Buy a new water pump, oil pump and timing belt. That motor sounds way too nice to fuck up because of something stupid. Worry about getting the car on the road before you worry about how much boost you are going to run. You are on a stock 14b, I'm no rocket scientist but, you may want to see how the car is running with a wideband before you start cranking boost up. I also highly recommend buying dsmlink before you start really turning the boost up. I don't know how much the computer can compensate for before it starts giving up. I also don't know how much fuel you are going to need for 20psi. Get it on the road first LOL

[Skoodles]

trey may do some damage to a turbo motor if he drives it the way he does his fuckus.

[Matticus]

Wonder where all the haters are that call me "cheap" that obviously know what they are talking about? :mattsgay:

How bout the people that talk shit on how long it took me to put my car together when you have yet to even build ONE car. :mynameisben:

you are cheap! lol

unless you have gold-plated turbo and motec then we will call you cheap haha

[Matticus]

I'm not Alley Kat either HAHAHAHA

here they are they are brand new never been used i bought years ago when i was building my 91 dsm

I may have missed something, but you can't base any of your upgrades on "how much psi" you want to run, unless you know which turbo you are going to use. For example, a stock t25 @15psi will not make as much power compared to a gt35r @ 15psi, this is due to the flow of the turbo of course.

and to correct a statement made earlier, dont go too large with the injectors(unless you need retarded big ones), because NO they can not ALL be tuned down to run like stock, if you go too big you will have stalling problems at idle due to too much fuel.

[mikesrex]

if you go too big you will have stalling problems at idle due to too much fuel.

never had trouble idling 1600's are there bigger injectors we can use?

[campos]

let me rephrase, it depends on wjat u are tuning with, some programs have a hard time controlling the larger injectors.

[Matticus]

dsmlink and AEM can control pretty much any injector he would want to run and the car will idle like stock.


But you are correct. Some "tuning devices" have a hard time controlling large injectors at idle.
