I had the exact same problem. Under load above 4000rpm (dependant on load situation) both on road and on dyno (ramped, etc) when accelerated hard my car would have a miss and sort of hesitation. If i eased on the accelerator, the problem did not occur. We changed fuel pump, had all injectors flow tested, etc, as they are brand new, and car still hesitated (missed). I WAS running NGK platinum plugs (gapped to 0.8mm) and the car still had same symptoms (exactly like you are saying). I have super tech valves with titanium retainers, etc, 1.5mm overized valves stainless on intake and nitrite coated on exhaust. My springs are 95pounds at the seat and still car hesitating under load. Problem was found that my spark plugs were arching out under load. (Simple rule of thumb for old school mechanics - plugs up top, points down low) checked my coil packs, they were fine. Changed the plugs to v-grove and solved my issues instantly. Have also since put SplitFire coil packs and HKS plugs. I was running 12psi when this was occurring so had nothing to do with coil binding or a dud valve spring.

That's just my two cents. Hope this info helps.

I'll mention this when I speak to them today. Cheers for the input ;).

A 9174 would just make the EGP pressure issue worse and in my mind it seems like a bit of a GT RS shit going on. Not that it's horrendously bad (It wouldn't be no twin buttplug pressures), That's NOT

Paul I know you mentioned the timing looked good but might pay to call ross about the trigger kit a local company here in bris was having miss fire issues on there car and they traced it back to something in the trigger kit arrangement. Sorry this is second hand information so i dont all the details but thought was worth a mention..

We had what seems to be that issue you're talking about in 2011 when I put this kit on. The issue for us was the GT101 sensor was not PERFECTLY in line with the trigger wheel. New bracket has since been made. There's no logs of issues with timing or anything. When we had that issue we were seeing RPM logs of 86,000 RPM, 44,000RPM and would be hitting the RPM cut. Sound similar?

Again this is second hand info but they were talking another revision something to do with the cam sensor though.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Did you panel beat the dents or have you tried to repair this only using filler?  Is your sanding block soft/flexible and is following the shape of the panel rather then just knocking down the high points?

      I haven't knocked them down yet. I think I made the repair more complex than it should have been. I had rock chips combined with waviness and dents and I tackled it all in one because it was near each other and just end up wasting a bunch of bog lol. I'll knock down those areas and see how I go. And yep what you are saying at the end is correct. I think I might be sanding the top of a steep hill then my sanding block falls into the dent and gets rid of the guidecoat if that makes sense. Though shouldnt unless I'm covering too big of an area with not a long enough block. I'll try something new and provide some updates. Getting there though! Thanks as always.

      Yeah makes sense, hard to comment on your situation without seeing what your doing. I was talking generally before, I would not be looking to randomly create low spots with a hammer to then have to fill them.  It's hard without seeing what your doing, it sounds like you are using the guide coat to identify low spots, as you're saying the panel is still wavy. I don't see how you're not ending up with patches of guide coat remaining in a wavy panel? Once the high spots are knocked down to the correct level, surely to have a wavy panel you need low spots. And those low spots would have guide coat still in them?

      So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
