hey everyone....
i have just recently finishd putting a RB25 into my 32 and its all running sweet except for.... sumfin which is giving me the shits
As i come on to boost and get up to about 4rpm or so the exhaust starts popping and backfiring.... simliar to as if i had a REVLIMITER "which i dont" and when this is happening im loosing power and acceleration...
ATM it only has cooler, exhaust and fuel pump "as i am a lil low on funds atm "
and its running stock boost.
does anyone what my problem may be... iv been told its the coilpacks and sum ppl also said its the fuel pump....
but i want more opinions b4 i do anyfin. Your help would be much appreciated
thanks
josh
