ok here's da scoop! I got a D15B2(DPFI) and i just installed a DC Sports Header (I removed the CAT.), I Greddy Thrust cat-bac exhust, An AEM cold-air intake, and lastly a walbro 255lph fuel pump. now all of this is on my stock DPFI injectors and i figure that would be a little to much for my stock injectors. I am going to get a MPFI swap But Money is a little tight with me being in College. Ok so heres the Question: when i rev the rpm, i get a liitle blue smoke out the exhust. is this because i'm running a little rich? Or Should I put on a Cat.? I kno the D15B2 doesnt take good to bolt ons.

 

i guess the smoke can be black but it also looks blue i just say that because if the 255lph fuel pump on the stock DPFI injectors and the car also tries to stall out at low RPM's

 

Yeah with those mods, you're putting down some serious horsepowers. Might want to upgrade to 1000cc injectors and a stage 5 clutch while you're at it.

 

Simple compression test your motor. No more it looks liek this or that. get low #'s its oil
