We have helped one of our friends in his homemade turbo kit for the ga16, in order to give an idea the car got the following components
Custom tubular turbo header
Mitsubishi Tdo4 (wrx) turbo
WRX subaru top mount intercooler and BOV, fitted as top mount
Two high impendance 420 cc Additional injectors
Msd Dis-2
External coil
act clutch
Lightweight flywheel
stock internals
210 LPH fuel pump
Fuel pressure regulator 1:1 (stock have been removed)
Runing unichip with timing and fueling control, with a turbo module (using a 2,5 absolute map sensor) to controll de aditional injectors on a 3d mapping (by laptop).
Runing 8 psi of boost, and tuned with an NTK wide band O2 sensor, producing nice and clean power.
Downside so far is the head gasket. WE never used the stock one, we receive one made locally, but it did not hold.
This car was tuned N/A first, so the head were resurfaced to increase compresion. The head gasket used was 3 mm width.
No nocking, egt bellow 1250 F (probe on downpipe), A/R ratios 12,5 at 8 psi of boost, on cylinder 4 the head gasket has blown, water getting into cylinder producing misifire and probable overheating troubles.
We need someone who could make an MLS (preffered head gasket) at least 2,5 mm thick (or maybe use two thinner ones)
I will post some pics for you, this kit was under 1300 USD

As far as I know, no one makes a MLS head gasket for a GA16DE. However the stock one holds up to reasonable boost ok. Thick head gaskets are not the way to go with turbo motors, they eliminate quench and are more prone to blowing out.
You might be able to get a copper gasket custom made but they are not really streetable, they will always ooze a small amount of coolent.

try out the OEM one, my has leaked yet and it has 80,000miles on it with ~5lbs of boost. as far as i know, my youngs hasnt had any problems with his either, and he is running 8psi. if u want copper, i think that louis said he could get ahold of some
Cometic is a good gasket manufacturer. if u send them an OEM gasket, im sure they can make a multi layer steel gasket for u. i have no idea how much it will cost though.
Originally posted by James no more than 8psi. I'm using the s14 turbo w/ a 97 240sx MAF... same as the Project car. I don't plan on anything higher than that....
Hopefully the stage 2 programming will be finished in the next 2 weeks... This time I have to apologize.. I just haven't had time to get the car down to JWT... Hopefully I will be able to get it down there by wednesday. I've been fighting a flu bug and we had to wait for a couple of parts. Good news though... JWT will also complete the water injection daughter board for the ecu at the same time, so all those that would like to add a Auqamist sytem down the road will have a management system ready to go.
That's great to hear! I just talked to Ben down there and he was going to send me the ecu with the 1.6 maf program until the 240 maf one could be finished! But I guess he can just finish it now and send it complete!

yeah you might as well hold off a little longer.. since you've waited this long already... I'll make sure I update you as soon as it's available..
