4G64 TURBO help!!

[willye_br]

Hey guys,

i have a 1999 spyder 2.4L 4G64. i read a bunch of threads about 4g64 trubo and i have been told in this forum that if i want to turbo my car i can just use the 2g gst or gsx Basically exhaust manifold, injectors, oilpan, turbo, bov, intake, just transfer the turbo system from a gst to my spyder as a bolt on. All i want is the basic 8 PSI setup just for the blow off valve and make it a little faster thats all. I been trying to get all GST parts used and a good turbo to complete my system but do i need to replace my pistons? will my pistons be ok with only 8 psi? if anybody here that has a turbo dsm could spend 3 mins telling me the gst parts i need to get to make my spyder a turbo i would really appreciate it because i see turbo dsms in my area all the time and they are sick.

Thanks a lot guys.

Thats like a HP question, you will get different answers every time.

FYI You can slap a 4g63 (1g or 2G) head on your car, but you will need to have a machine shop plug some oil drain holes.

Intercooler - Stock 2G SMIC OK, FMIC better.
Intercooler Piping from turbo to intercooler & intercooler to throttle body (custom connector needed for stock throttle body connection).

To answer your other question, no your pistons do no limit you. Having those pistons in there only means that you are limited to how much boost you can run since the high compression is more prone to knock, but the positive is that because you have higher compression you will make more power than if you had the lower compression pistons. Lastly you can't use 4g63t pistons you have to get 4g64 pistons. By the way, stay away from AFC's.

Get yourself at minimum a turbo ecu, afc, datalogger and a wideband o2. You will need to fab up a lower radiator hose depending on how you route your intake pipe. Also something to worry about is the thermostat outlet. It points right into the intake pipe so you need to find someway to point the outlet down or do what i did and modify a adjustable swivel chevy thermostat housing to work on the car.
