I just picked up a procharger head unit for cheap and was wandering what else I will need for the install. It will be going on a 92' with a GT40 crate motor and plan on keeping the boost low (around 8-10lbs). I know i will need pullies and piping and Im gonna go with an air to air intercooler. I dont know what other goodies Im gonna need to make it work. Can anyone fill me in on the other odds and ends i will need.

 

what year is your car? look in the stickies! if not sell it to me!!!

 

255 lph fuel pump, 42 lb injectors no less, and what ignition are you running msd? the reason why I ask is a msd retard box {timing control} would probably be a good idea what mass air meter do you have?

 

are you running IC or Direct? How are you tuning it? What head unit?

 

I have the fuel pump but only 24# injectors, was hoping they would be enough with low boost, guess not. I have a MSD 6al and a 75 mass air meter but I have a 90 laying around from a buddys car. Im not sure on the tune yet and I dont have the head unit in front of me but I want to say its a D1?... maybe. I didnt know if I would need blow off valves and things like that used for turbos. The retard box deff sounds like a good idea and I will have to look into the price of getting it tuned (didnt think of that$$).

They wont sell it to you though. You must get stuff through a distributor. I am one.

 

I would suggest a blow off valve for driveability reasons when you let off the gas the car will sputter without one, but listen make sure you plumb the bpv back into your discharge tube its metered air, the computer has already compensated for that air the car will not run correctly when the bpv opens and releases the air into the atmosphere. by the way maybe with a good tune you can get by with just 24 lb injectors but you wont get the full potential from that gt-40 motor its going to want more gas
