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.

 

[Andrew85cm]

Yeah replace those plugs stockers have been sitting forever.

Dont worry about Dyno #'s you don't drive a Supra lol. Just start add parts from there. Wish my RB20 was that Strong, I had to add intakemanifold, FMIC full exhuast and 14psi to hit 240hp.

 

[sx_drifter]

i have a quick question does the rb20 use Z32 N/a spark plugs?

 

[Twistex]

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!

 

[s14-240]

hmm, normally turbo plugs spark colder. I use 300zx tt plugs.

 

[Carl H]

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.

 

[sx_drifter]

i have heard that you are suppose to use ka24e plugs

my car dynoed at 206hp 196 ftlbs

car has aem filter, test pipe, 2.5 inch catback, and walbro 255 everything else is stock.

here is some pics of it on the dyno

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"
