i think its a 93 or so .. i got the clip with 12k miles on it .. really clean. installed a fmic and re-gapped the original plugs. put a profec b boost controller set at 13 psi and dyno 231 hp and 216 tq to wheels on a dynojet. 91 octain everything else stock. stock downpipe with no cat or exhaust when i dyno it. i dyno all my cars on same dyno so i can compare.. people in my area say that 1 or 3 dynos that read low in our area .. so im going to guess those number are more right than the other dynos i could have pulled more hp from. i re-gapped plugs because i was getting a misfire from 4200 to 4800 rpm ! im guessing to much boost was blowing out the spark on the plugs ?

power sounds about right, misfire is proly due to plugs and old coils.

i tried running those n/a plugs and car had a miss at idle .. ran like shit. so i put my old plugs in .. my motor only had 12k miles on it when i got it and the plugs looked good. from sitting a while i guess they could go bad!

um the correct plugs to use are from a z31 turbo, not a z32.
bpcr6e is the pn iirc, should be good for most ppl under 250-300hp, then after you get there step it up to 7's.

Here's the funny thing, Autozone.com lists the Bosch PLlatinum plug for the Z31(1987 turbo) as a "4201" and for the Z32(94 turbo), its "4201".

For an S13(1989), its a "4229", for an S13(1992) its a "4201" and on an S14(1996) its a "4202"
