only difference between the turbos linked to is the size. They're both very low budget cheap copys. they're not good and my conscience wont let me not tell you they're shit and that you shouldn't use them

Those turbo's are cheap nasty chinese rip off's.

The real GT3076R is about £900. So one thats new for 1/3rd of the price should tell you something about it. It will probably perform 1/3rd as good as the real thing.

well le me be the tes pilot for these turbo's before anyone else wastes here money, i'll do a review on the fitting, then the car will be dynoed and i'll post the print outs, and the next track is on the 14th feb @ elvington and i'll be thrashing the hell out of it, so hang on till then.

Also in my experience with chinese products (garage equipment) they are shite!!!!!! but in there defence if you are prepared to use it as a disposable item, there are a buget option but don't expect them to have a 1/3 of the life span

so, as a silly question, what is the real difference in buying a cheap turbo to one thats nearly a K, lets say a GT30/35.. then, they all do the same job by basicly blowing air into the engine, can any one advise.. im looking at a cheap one myself..

prbley the quality of the metal, casting, and assembly.

The GT3076R spins up to 145,000 rpm.

So when you try to save costs, any imbalance on really cheap bearings will fail alot early than the finely balanced Garrett unit with much more expensive bearings.

The castings probably don't make much difference though unless they're reallllly crap.

May pop down and see you at Elvington, not that far from me, would be good to see it in action and give another view on the fitment performance etc (although I'm no expert.)

Interesting thread this, So in retrospect a well rebuilt standard T2 should outlast most cheap turbo's.

All secondhand turbo's to me all look like they could do with a good rebuild, what would be the cost of rebuilding DIY or having it done by a specialist???

Is it hard to rebuild a turbo???

Are there good and bad rebuild kits available???
