Hey guys,

I have a ba xr6t

The last few days all of a sudden while driving the car would start making a crunching/whining noise coming from under the bonnet and I noticed on my ultragauge that it would not be making any boost and the noise would change with the revs of the engine. But then all of a sudden after 10-30 seconds it would make a bad crunching noise and then disappear completely and the car would make boost again. It keep doing this, and happens even under light load while driving

I managed to replicate the sound with the car parked and it sounds like it is coming from the turbo.

also after shutting off the car I can hear the turbo spinning for a along time which ive heard is common but it really doesn't sound healthy.

If my turbo really is shagged then what is the cheapest option considering my T is just a daily hack while ive got an R34 that ive just bought a new turbo for so I have the old GT3076 from that available for the xr6?

If it's a daily car, you could just get a replacement Turbo from another BA XR6T, or if you want better response and low down power you can put a FG Turbo on it and get it Tuned to suit

Just take the turbo off mate make it na then your r34 will be faster than the falc just hollow out the turbo with a hole saw then it wont be a restriction it will be cheap as.Or sell the skyline and use funds to buy an atomic bottom end and big turbo.

I would just buy a turbo core of ebay for $600 ,and fit it to the car .the core comes with standard turbo wheel so it does not need a new tune .ps to fit it inside the turbo is ease ,but to take the turbo off is another thing .I would take the manifold off with the turbo attached to it . before you try to fit the core make sure that you mark the housing so that you remember where the outlet was facing . its really not that bad ,just time consuming .

Yeah ive had the turbo on and off 4 times already for different problems so now its time for new turbo lol.

Hmm I see $700 cores?

How bad are the $350 yum cha turbos on ebay? considering I wouldn't ever run more than ~9psi

yes mate ,Spyathe bought one from over seas for $390 delivered .I believe he is happy with it .
