I have a 87 turbo 2. I will have a k&n air filter and a complete racing beat exhaust, everything else on the engine is stock. I would like to know what fuel pump, injectors, ect. I need to be able to support about 250 to 300 hp. please tell me everything I will need. I am trying not to spend to much money but I want more power.

I also need to know how much boost I can push out my stock turbo without blowing it up. I am guessing that is what I will have to upgrade next.

thanks

 

ok first hope you have the FCD, if your on a budget get the welbro 255lph pump, a fuel control,800cc secondary injectors. the stock turbo will do 18 psi but the harder you push it you lower it's efficancy and rise air temp this causees a mass of new problems. so a bigger turbo is perferable after the fuel mods but make sure you alway up the fuel and dyno it back down to make sure you don't blow it. good luck

 

amemiya, you done 18 psi on a gtr turbo????

 

Stock turbos will **** themselves over 14 psi man...

 

I had a bonestock 88 turbo motor in my first gen with stock injectors, a bosch pump (don't knwo which one), large front mount, cartech fpr, and of course the stock turbo and it pushed 13.5 psi. Oh yeah 3 inch mandrel bent exhaust with no catty. It mad 280.1 rwhp which is well over 300 engine hp more like 325-330. I daily drove this for 6 months before it blew up.
