Looked at an SR20DET today that i was planning on buying ive seen it looks clean sounds really clean at idle BUUTTTT!!!...when you start to drive it and after like 5 minutes at idle it starts to make a really whining noise...i really dont know what it could be im just lost on this one...only thing i can come up with is maybe the turbo is going out since its just a stock t25...ill try to go again tomorrow look at it try to come up with a deal with the guy but until then i want some advice on this and ill try to post a video tomorrow if i go so you guys can see and hear of what im talking about. thanks in advance:cry:

does it whine when boosting?

Turbo probably is shot, Check for shaft play

could be something in the block, i've seen so motors start to whine from the bottom end once warmed up.

whines at boost and at no boost...the owner thinks its cams but i just dont understand why the cams would whine or even anything in the block

well the Cams will squeak if you have no oil flowing to the head.

Verify you have oil pressure and oil flowing to the head before driving that car any further

odds are its the belts. check the belts if they have slack. if so just tighten them

its not the belts for the 5th time they were off and when on they were tight enough for it not to squeek or whine...BUT!!.the turbo has shaft play and an actual sr owner told me its the turbo in its early stages going out

Yea I second the turbo but it could be the rod bearings - they do good bad... and then they make a horrific whining noise - then a piston flies out the side of the block... speaking from experience...

turbo being held by one bolt and the gasket flapping around creating the whining noise as if you would put a piece of paper between your lips and blow haha

It wouldntve been a rob bearing. I spun a rod bearing literally two weeks ago and its not a whining sound, its more like a knocking sound.. But hey at least you found out the problem, now go to t28 :D
