Looks good stocky.. Any plans to get that s/c providing a little more boost in the low end?

Good results... What sort of duration and lift did you end up getting out of the reground cams?

Nope, you throw it in diag mode and it runs its tests and throws out a code (by flashing a light (dash light or light on the ecu). You count the flashes and then compare the number to that in a list. It then may show something like code blah... coolant temp sensor or code blah afm etc etc.. You can even throw it in an o2 test mode where it flashes the light as the o2 sensor goes high/low. An easy way to determine if your o2 sensor is shagged, lazy, or not.

Ripping the kick pad off and putting the ecu in to diag mode is a hell of a lot easier and quick (2minutes) than changing a fuel pump. Might get expensive if its not a fuel pump and turns out to be an AFM or something.

The Op's has been having a miss problem; likely to be related to ignition. Your ignition system clearly is perfectly fine and your det is simply too much ign. As I mentioned with shagged coil packs on 2 different cars I have observed an increase in knock over what was before a perfect low knock tune in all conditions. Most likely not the case here and most likely just a tune issue. But I thought it would be usefull to mention it. 75knock really is too high, might be worth taking the car back for a touch up as a load condition may have been missed when it was on the dyno. It is difficult to simulate road conditions on a dyno; which is why its so important the tuner takes it for a quick spin. From what I've seen the dyno tends to miss partial throttle on boost load points and low rpm high gear (up hill) lugs where it makes reasonable boost; even though on the dyno we did hit these load points on the road it was 'just different'.

Search for how to throw the R33's ecu in to diag mode. It will then output any faulty sensors. Hopefully. The fuel and afm check you may not be able to do by the sounds of it... Might be worth dropping it off to some one who knows these cars as no doubt they will find the issue quick smart.

You have definitely had a little bad luck.. That old saying.. Things happen in 3's. :S Whats the third. Waiting for pics.

Yes edwardstown is a tad close. Where was the car found DC_GTST? Damage report?

Time to throw the ecu in to diag mode. Test fuel & afm .

How is it when you put the boot in? Have you looked at fuel supply?

Minus is minus.. So you need minus 3 degree's.

PUS16; The 602hp was that the fly or wheels?

Mad082, Does it hold the 14psi to redline or does it tail off?

lmao mr make full boost by 3500rpm keyboard warrior. So your telling me the GT3040 .63 hot side will make complete use of the compressors air flow ability. hrmm why is it Garrett didnt release such a combination...... Its not just lag its also response that will be affected by running a large compressor. For the power this blokes after a GT3071r will be perfectly fine, offer better response than the GT3040 and still make the power he's after. I've seen a GT2871r make 240rwkw with stock like spool on an rb25. I'll try to dig up the dyno sheet from the dyno day.

Why would you want all that compressor flow when the hot side is unable to support it. Your trading nothing for............... lag.

If thats the case go for something you are familiar with.. The GT2876r should get you around 240rwkw.

The GCG Highflow is a BB turbo and works damn well on the rb25's. Do a little search for "GCG Highflow"

Yes I've heard about your little build. Very nice. How is it coming along?

Interesting... Post picks.

Grab a GCG Highflow for that sort of power. I think SydneyKids group buy for $1750 or there abouts is still running. The GCG Highflows bolt straight up with no more to spend. Buy something that doesn't bolt up and your up for another $200-$300 worth in sorting out silicon hoses and water/oil lines not to mention another $300 odd for a custom dump pipe.

A learning curve it was and still is. Did you run 2 x 1.5mm Tomei restrictors or just the one? I believe the RB25's run 1.5mm restrictors from factory?!?

Thanks Rob. I'll replace it for good measure; something I should have done some time ago.

With regards to misfiring. I and Bl4ck32 have coils that are on their last legs, we have both observed increased knock levels when the misfire occurs. Not always but often.

Thanks FatGTS-R. The pump is what I would consider long in the tooth. Its around 4.5yrs old and as mentioned around 135,000km's old, well maybe closer to 145,000km's. Tomorrow I'll ensure the turbo to afm pipe isn't split or leaking as I'm sure this could also do what I am experiencing.

Std injectors won't handle 1 bar of boost from a GT3071r.
