the turbo is not spinning at idle when fully warmd up... spins past 1k rpms... but below it will not... could it be because of the oil return line... the oil return line sits slightly lower than the fitting where it goes back into the pan... could the oil be going back to the turbo and not returning back to the pan; causing it not to spin (too much oil)...? or are the seals bad... turbo is brand new just idled... if u give it gas it will spin again.... any help would be great...

 

what turbo and motor

 

precision sc60 and d series y7block y8 head

 

I just helped in doing a sc61 setup on a h22 and it does not spin at idle.

If it were bad seals, you would be leaking oil all over the exhaust housing usually

 

i installed a tubo kit on a h22, and it barely spun, it was a brand new kit, nothing to worry about.

 

did you completly tighten your bolts on the compressor housing?

one time on my buddies integra, his bolts was all loose and one of them fell off - causing it to not spin during idle.

but like they say, big turbos and small engine - it's just not pulling enough vaccumm to make it spin!

With the car off, make sure you can spin it with your fingers ... as long as it turns freely you should be fine.

My SC34 does not spin at idle on my LS.

pulling enough vacuum?

i think you mean its not flowing enough exhaust gas

 

thats weird
i have an sc61 with p-trim wheel , it spins on idle nicely just like ball bearing
i have a b18c1

It would be a combonation of both vacuum and exhaust pressure. At idle a motor is in vacuum, naturally pulling air in through the turbo compressor housing. If it had more vacuum it could in theory suck air in through the compressor turbine blades fast enough to spin the turbine .... transversely if it were to push out more exhaust gas through the exhaust housing that too could make the turbine spin ...

Please attempt to think before ridiculing someone

 

...or if its like most honda turbo setups, the blow off valve is open at idle and virtually no vacuum is pulled through the compressor.

 

If the BOV is open then wouldnt it be a good idea to put a filter on the BOV? or is sucking dirt into the engine through the BOV acceptable.

Thats a good point ..... I'm gonna have to go start my car and put my hand on the BOV and see if its suckin in ....
