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 ;).

Small update.... ITS RUNNING. Fired first go! Smells like burnt dust apparently .

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.

      What accelerator cable can be used with greddy plenum

      By Duncan · Posted

      I was 99% sure the standard one is long enough to get there, you might just have to change the throttle orientation. If not, I remember someone having used an r31 cable instead, but that is probably harder to find than r33 by now...

      HELP   Hey all, Is there an accelerator cable from another Nissan that can be used on the R33 GTST RB25DET with a Greddy forward facing plenum?  Thanks in advance  Rob

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Or do we think it was installed to give 1 bar of boost max, all day, everyday?

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit?

      What should I do next to hold the head on

      By Gareth87 · Posted

      Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!
