Cuting Out

[vrkt33]

just wondering, on my skyline 33 i have installed a cooler, boost controler, exhaust, pod and bov, at high revs when giving it the car starts to choke, cut out, just wondering if its the coil pack that need to be changed or do i need a new fuel pump??

Is it RB25DET??? if yes i had same problem on it:) just what you need to do to move ignition a little bit left on 2 or 3 mm and it will be ok:) speccialy if you will boost it up to 11 PSI:)

thats advancing the timing you really need a timing light but for me id lower the plug gap.ive just been thru a whole year of that !and at first needed like 27 deg + timing but recently put some copper plugs in @.5( imay have got away with .6) but the iriduims at .66 were still spitting

since the .5 ive been able to bring the timing back to 15 deg without spitting and happy im no longer in pinging a motor to death anymore.

if you had slitfires id say .8 but std coils maybe .6.

I new to turbs tho but not horsepower
