Without knowing the noise i'll give you a couple of scenarios:

A/ If the turbo was you received was not clocked correctly theres a good chance the either the exhaust inlet is not tight or the intake pipe in not aligned prperly causing a leak.

B/ If the turbo is a bush baring have they drilled out the oil feel banjo from the block?

C/ Did they run a flush through the engine first as these cars if not serviced properly can have bad oil feed problems? I gather you did put new oil in?

D/ The turbo has not been built properly so the wheels are rubbing against the housing.

If the waste gate is not working properly it wont make a noise......it will however either generate boost at WOT towards the end of the rev limit or will develop to much boost.

P.S. Regardless......all of the above means the turbo will have to come back off.

Free spinning turbo. Just as I turn off the car I can still hear the fan of the turbo spinning

Loud clunk noise when coming off boost....

If you can hear the turbo spinning after it's shut down; that's a good thing. Well balanced, good cartridge.

As for the clunk; not so sure. Wastegate snapping shut, bov opening?

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻

      Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”

      Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
