Yep, exhaust getting sorted tomorrow. Think you're right re: TPS because once revs are over 2k she goes like a rocket till redline with no signs of boost loss, missfire, ignition retard etc

When i give 'er some revs in neutral the engine stutters for a second or two till the revs build up. I have gone round tightening everything i can think of. I have found a small (20mm) long open section where the zorst guy hasnt welded the resonator up properly. Also, when i rev i think i can hear a whistling sound from the AFM which is located just after the FMIC and prior to Greddy plenum. Question is....which one or both? Any ideas Thanks

Any?

Just got my car back from the workshop. I noticed this morning whenever i put my foot down on the clutch i can hear a compressed air sound which disappears when i release the clutch. Any ideas? There was no clutch/box work being done, just a greddy plenum being installed. Any help appreciated (r33 gts-t S1)

on the money with the plate rattle. good to know that was normal

Nah, never did...having said that i've got some really good rubber and a very aggressive camber, castor, toe out set up for the track, so it takes a bit to get it to chirp. Only thing i can think of is it will chirp less as the clutch beds itself in maybe?

Been running the exedy hyper twin for about 3000km. still a very aggressive take up, but as previously mentioned, i definately became more cautious about how i released the pedal.

has anybody heard of or been to extreme machines ??? PM sent

Thanks guys for your suggestions. i think i will go with the .82. One other question...does the 3076r provide more of a gradual delivery?, unlike the 35 which kicks like a mule.

I currently have an R33 RB25DET running poncams, GT3540, and supporting mods. I was recently told that if i were to swap out my 3540r .82 for a 3076r .63 i would still make around 400rwhp with more response and less lag. This was appealing to me as i have just began taking it out on the track and can always do with a tad more response. Please help out a novice racer by confirming or rebutting this opinion. Thanks

Hey Nismoid, thats pretty much exactly how it behaves on gearchange. Now that i know this is normal for this setup i wont go spending a ton of cash trying to fix it! Thanks everyone for the input

Thanks for the reply.....yeah should have said. It has an atmo BOV with a soft and hard setting. I think it may be on too soft. I will adjust it and see what happens. It was on the car when i bought it...is the adjustment option just a rice thing?
