I have a 95 civic with a b16a2. I got the motor in drove it for a while and it is a strong motor. I than got a turbonetics t3/t4 turbo kit, we got that on and now around 5000 to 5500 rpms it starts to back fire and loose all power. Everyone told me that its the fuel but i have since than got a new fuel rail, 440cc injectors, walbro fuel pump, ajustable pressure regulator and had it on the dyno. i was just wondering if ne one out there had ne suggestions on what might be the problem.
oh yeah im boosting at 7psi..... and when its cold it runs good.

 

Get that thing tuned! i thing 440's are a little high with 7 psi. u can get greddy 6psi kits and retain ur stock injectors just using a FMU ect. you shouldnt be any higher than 340-350cc on the injectors

 

What type of engine management are you using?

But what about track days when you want to up the boost? If you got the greddy kit, would you be limiited to 340-350cc injectors?

Need to know the exact set up in order to offer any help.

 

I had the same problem before. What was causing the problem for me was the distributor was going out.
