I've seen one set up on an tough as nails.ls1 before, on the v8 it sound good both open and closed. on sides they seem to be either too raspy open or to muffeled and choppy closed.

Alot of new cars have them butterfly valves standard but they're not legal as an aftermarket item (i can only speak about in nsw as im unaware of other states rules)

when i got my exhaust done, i wanted to go 3" with the valve for 2 -3psi of back pressure like the r8's have, Liverpool exhaust said they can fit it but have to warn me it isn't legal, i then asked about the varex mufflers, same. I decided to stick with the 2.5"

but to roughly sum it up, in nsw if it can be adjusted its illegal but with exceptions

probley should re word that, cause according to that a coke can could be used lol.

as I've said before i had a nismo oval on mine for a while and it was good. other than that i haven't really heard many na's where i know the muffler brand.

If you could find the guy that owns "ftw 33" he may be of more use.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.

      A bit late but A disk S13P fit over stock R32 GTR brakes, usually A disk front, O disk rear works.

      Or, the height of the release bearing is not correct for your combo. Start with the bleeding and checking the slave moves throughout its range when you press the pedal (2 person required), but it is possible for the height to be internally wrong too (box back off to measure.

      Yes, there's quite a few things that can go wrong during a clutch install. Very unlikely. I have a similar clutch. They (ACS) make good gear. No, it is not normal. It is possible that you just need to bleed the clutch slave. But the new clutch will also have a more aggressive actuation force/pressure, and so your old slave cylinder might be a bit leaky or otherwise compromised, and not up to the extra force required. Or the master cylinder, same.

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?
