87-88 pulsar plugs same as rb20 but 1 heat range colder gimme a few hours and ill have the number for you i am running them now they are ngk g power runs amazing also running hks exaust fmic and what i assume is a low impul ecu tune on stock boost

[Skym]

With the mods on your car I wouldn't go above 12psi (roughly the lowest you can go with stock internal wastegate actuator, boost controller) with stock ECU tune to get a fairly safe A/F ratio (it probably will be leaner than it should be at lower rpm's but not excessive) and would recommend you get a ECU retune (Nistune) to solve the lean problem.

If retune ECU (Nistune) and add bigger fuelpump, adjustable FPR, Z32 MAF, Z32 MAF plug, bigger turbo, metal headgasket you can push to the limit's of stock injectors, but upgrading injectors is better.

what psi can the stock fuel pump and injectors handle? like can i run 16 or 18 lbs? i dont mind pushing it to its limits

[danwit]

At 14psi they should be gapped .8mm.

ive got that need em now kid moment goin on... ill go get the oem ones napa has em in stock for 14.79$ each haha, should i leave 1.1mm gap or gap to .8?

[RABBIT]

just order online then , order a bunch should take well under a week.
Or go into a crappy tire and get them on special order.

ya cant find em anywhere... also im thinking my miss might be an ignitor, got new coils (landed today ) gunna throw them in later and pray my miss is gone, should i use the stock plug with stock 1.1mm gap or the autolites i have in it now and regap them to .8? im running a t28ballbearing, intake, exhaust, 14lbs boost and a fmic. will have yellowjackets in as well
