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?

      How old is the battery, it's more likely your battery is on its way out.

      I reckon you'd get 90% off. My washer doesn't get between spokes very well. Haha! I love my Gerni!  Argh! Steam cleaning has its place for sure.

      R34 GTT idle problem

      By silviaz · Posted

      Hey all, I did a voltage test with the car (video attached) not running for 3 days. And here is some interesting stuff: - Battery voltage is 12v (I had the key in the ON position) - Drops to 9.76v while cranking then quickly goes up to 14.5v - You will notice there was a sorta slow start but not as slow as it usually is. - Idle surprisingly was better at just over 1,000rpm instead of 1,100 rpm. - I turned on the A/C, radio and headlights in the video and the voltage remains the same - I haven't cleaned the grounding wires on the chassis yet, that's next. - Battery drops to 12.6v when I turn off the car and wait a bit Seems like I might have a parasitic draw? I do have an immobiliser system which does drain the battery more of course but was wondering if there is anything else I should be looking at fixing? Does the ground wires on the chassis have anything to do with the low 12v?        SAU.avi

      My lord that is some low oil pressure as minimum in the manual! I guess the big part will be seeing how it changes as the engine gets more spirited use.
