Chinese Turbos And Rebuilds

[Os8472]

I know the old saying 'never buy a Chinese copy' but I've seen a few people use these cheap chinese turbos, some with half decent results.

Is it worth buying these cheap turbos and then having them rebuilt with decent bearings and seals?

I would have thought if your gonna bother rebuilding it anyway, you'd be better off but buying a cheap garrett with nackard seals and rebuilding that.

Thought about that but there's bugger all the right sorta size that I need

Don't be tight, just buy a proper one straight away, probably cheaper in the long run!

All I can say is ask turbo ted! All the **** he's given his Chinese/garret internals, 30psi was it?
Not a mm of play!!!!!! So I'm expecting a life time of boost at 20psi with it lol

Best asking him what and where he got it rebuilt

See you buy a t34 off eBay- send it blunty for it to have genuine garrett 360* put in it for £285 So can you buy a genuine t34 for 430 quid?

Bet some one will post a link now.....FAIL for me

[turbo ted]

buy a chinese turbo for £150 quid and then take it to turbo developments for a rebuild with genuine garrett 360 thrust bearing at £120 quid,total £270 dyno tested and santa pod trashed.

Ive done the cheap turbo thing and sure it works ok if you put some decent innards in, but it wont perform anything like a modern GT garrett or similar. Wheel design has moved on leaps and bounds. If you can afford it, put the extra to it and buy a GT2871R, it'll last forever, it'll be ball bearing and theres good prices to be had if you do your homework. If you're really on a budget then fair enough, just make sure you have it built up with real bearings before you use it.

That one I sold you lasted 6 months was it with Chinese internals?

I decent roller bearing turbo is my end target and for the difference in cost between a GT2871r and GT3971r I'd go for the GT3071r but facts are these I don't have a spare grand+ sitting round and even if I did itd probably spent on the car anyway but I don't and the turbo I have right now is way too small for the job and if I wanna make national day with a half decent amount of power I'm going to have to go with the cheap option for the short term and before everyone starts saying "the cash I'll spend the cheap job could go towards the BB job" I know but I have to much to get done between now and national day for me to afford the BB job

I recently proffed a 1000mile nearly new Ball Bearing GT2554R from ebay with all the paperwork to back it up for less than 300 notes.

Not tested it yet mind, not sure how it will perform with a .64 back end - anyone know where is cheap to get a smaller rear housing? - or got one and can let me know?

Not all BB turbos last as they should, my last one went pop after 2 events, and i doubt they will honour the warranty, i am sending it back to OD for investigation though, millers 10-60 competition oil (60 odd quid a go), inline filter and good oil pressure...

If i were you i would get a knackered garrett journal blower and rebuild that though as Scoff says... best of both worlds that way.

I blagged my Garrett GT28RS for 600 sheets cash brand new, the deals are there if your trawl for them

Thats the upside of a long lasting build, you have enough time to sort yourself cheap parts

Bought the T28 for €100 from Marktplaats. The guy said it needed a rebuild because it had radial play. Actually there's nothing wrong with it
