Hear are my mods...(r32 RB20)

FMIC, Full 3" Exhaust. 3" dump/front pipe. HKS POD, GFB BOV, HKS cam gears, and timing advanced a tad.

Hears my prob...

Ive raised boost up to 10psi, tried pushing it a tad further for sum fun ( knowing i could cause damage) and once boost reaches its full potential the car seems to stutter (Misfire) but if i gradually build up the boost it doesnt seem to have this problem?

Any ideas?

take out your spark plugs, use a feeler gauge set [buy a set for around $15, can get bigger better sets for more], and squeeze your plug gap down to 0.80mm, it will be set to 1.0-1.1mm std.

Ask someone to show you how it's done, once your shown its easy, annoy your lawnmower shop or something [anything with a sparkplug], with a plug spanner, feeler gauges, and a spanner set for other bits and pieces, you'd get it done inside an hour or so.

No. Looking at the spark plug there's a bit that comes up from the centre of the plug to the end (the end that screws in). About a millimeter away from the end of that is a tab bent over that comes from the side. Making that gap shorter is this name of the game today. Don't let them touch, coils don't like it if they do.

My bet is that you have a standard ECU which will retard timing and run rich when you try and push boost past 10psi.

You need an aftermarket computer or a Apexi SAFC or similar at the very least.

Was thinking the same thing

      V36 coupe manual wreck

      By Pete_Repeat · Posted

      Anyone want to make me an offer to take my v36/g37 3.7l manual coupe in full? Off memory it was low 100k km but the battery is flat so can't tell right now. What's wrong. I had engine problem's that led to a nice clunk. It made it home but it wasn't pretty for the last few kms. Happened under revs. Sounds like bottom end.. never got around to fully checking or fixing it so the car has sat still and unregistered for a few years. Minor bump in front end set the pedestrian protection under bonnet airbag off and that was meant to be repaired, but while waiting for the repair (parts to come) I got the engine problem. The rest of the car is in decent condition. All drive line is good. All interior is good. Leather interior. Wheels in good condition and decent tyres although the ps4s are likely a little too old now it's sat still. Colour of the car is pewter off memory, the dark grey colour. In Camden NSW. Would need a tray back pickup.

      Turn signal wiring question

      By MBS206 · Posted

      I started with the above in my head too, and I might be reading / thinking about what they want wrong, which is why I complicated it a bit further. Purpose I'm seeing is for the corner indicator to be on with headlights, and then if the indicator turns on it can still flash. The relay part above I can see working as required, except in the case of headlight is on, and indicator is on. The change over relay you've wired in would get signal from the indicator, and as it flashes would give power to the globe from the indicator, but as it flashes off, power comes from the headlight, which would cause the indicator to be constantly on when headlight is on, even while indicator change over is flashing. That is unless we don't care if it flashes or not if the headlight is on? I guess that's an OP clarification.

      Speedo and odometer reading super slow r34gtt a/t

      By VicFlo · Posted

      HI, Ive got an r34 gtt sedan A/T. The instrument cluster went out and I replaced it with another A/T everything visually looks the same and all the gauges work now with the exception of the speedometer and odometer. The speedo will stay pinned at zero until I'm going about 55kmh and then it'll say Im going about 5kmh. my odometer seems to be tracking at about a 1/10 of what it should. If I go 1km it'll say I've only gone 0.01. Appreciate any and all help. Ive tried searching through the forums reddit and a local fb group. The only info I think I've found is that some cars didnt come equipped with TCS (mind is) and the clusters may be different between those? I've also installed a brand new VSS and no joy obviously. TIA.
