Before the onslaught... I tried to search but the button was broken .

Now... my spark plugs are fowled again and this is the 3rd set so im going to upgrade this time. What are the part numbers for some plugs for a modified ca? T3 turbo, 460cc injectors and ~7lbs... The stockies arnt cuttin it.

Those will fit but will not work. I need turbo plugs, espciacialy with the amount of air and fuel im pumping in.

just get a colder heat range, and lower the gap..

i think the ngk iridiums 7 heat range gaped to 32-38 would be good

but wait till someone who has more expeirence can answer ur questions..

These should work well with these mods but if stock heat range plugs are fouling then colder plugs are likely to be worse, I suspect you are running too rich or the spark is too weak so decrease the gap and check your air/fuel ratios and timing.

Ok i know the air/fuel was fuctup because it wasnt tuned before. But after the ecu chipping and z32 maf they were already fouled and it was never run with the new tune. Do you guys have the part number for those plugs?

"Other Spark Plug Options:PFR6/BCPR6's for standard (gap of 1.1mm)

PFR7/BCPR7's for lightly modded (gap of 0.8-10mm - see what works for you)

BCR8's for high boost applications. (gap 0.6-0.8 dependant on boost level)"

I run BCPR7E-11s myself. Gapped at .8mm and work great. But I have much less fuel and air than you (stock fuel save for Walbro and T25G @7psi).

Are you saying that they were fouled before you got it tuned for the mods that you have now? If you have an overfueling problem, changing sparkplugs isn't going to keep them from fouling. Also, what size turbo are you running? I seriously doubt you are going to need colder plugs unless you're making 250hp @ the flywheel.

Nevermind, I see that you've got a T3 now. But at only 7psi, they still shouldn't be fouling.

running NGK double platinums in mine.. PFR6A-11 gapped to 0.8mm per plug.. even run at 16 pound and no tuning with bigger injectors and these things didn't blow out or get fuelled out.. pretty awesome plugs me thinks !! otherwise, the BCPR6E plugs work great too.. they are the stock NGK plugs, and they lasted ages at 13 pound, but that was with normal a/f mixtures, normal injectors the let.. still worked good !
