R33 - does your boost hold to redline in 2nd?

[benl1981]

I'm running about 9-10psi but in 2nd gear the boost tends to trail off quite a bit after about 5000rpm. I reckon probably to about 6psi.

I have tried a couple of different boost control methods...all the same. I think it happens when it is stock aswell.

Feels a little flat whereas before it really took off after 5000rpm.

All the hoses seem fine. Could the actuator have deteriorated?

There is a couple of missing manifold bolts. Can't hear a leak though. Intercooler pipes etc are tight.

Chances are its got to do with the missing ech. manifold bolts.

What exhaust are you running?

I've got a 3" dump/front and 3 1/2inch cat back (kakimoto)

Bugger about the manifold bolts. I can't hear a leak. It is the front most bolt and the rearmost. I can see a tiny little soot around the front one but the rear seems to be still sealed perfectly..

Al the other bolts/studs appear to be intact. It just seemed to have more power up high when I first got it about 6 months ago.

Not looking foreard to pulling the turbo off. Also the rear stud might be hard to drill out (need compact drill???)

Thanks
