I take it they're all external gate turbos? If so they're still a decent price for a quality bit of gear

I took it to a supplier up here and he is planning to rip it apart just wants to have a look, I will NEVER fit it on again! JUNK!!! It cost me $850 for the turbo, $150 for the dump pipe, more for silicon hoses that are now useless to me as Garrettt have a larger opening, and lasted 2 - 3 laps of the block, utter JUNK Clay that was only ever running at 10 PSI too always had good oil, and was bought brand spanking new too..... All I can say is I dont do KKR's anymore!

Don't know the kkr trbos from a bar of soap, but it shouldn't **** it sept that quick unless there was somthing majorly wrong with it to start off with

KKR is dodgy! Clay

KKR is dodgy! Clay I would of checked oil was going through the turbo. No good it going to it if it won't come out the other side.

No good it going to it if it won't come out the other side. the turbo was getting ample oil, had a free return route too, but hey feel free to get yourself one of these awesome turbos!!! I think I will stick with the Garrett sitting on it now, I have more faith in it. Clay

I just thought If you had the engine running with the feed off the turbo to check it was getting oil well your turbo would be spinning without any oil. Even if a short period be enough to stuff it.

i had a kkr and didint have a drama with it at all , i would use kkr again (kkr 560)

Bear in mind this thread isn't bout kkr turbos. Hypergear aren't the same as kkr

ive got a monsta turbo with over 50,000 km on it and had no problems, wish i could say the same for the gtech manifold

Some of them turbos were actually built properly, some being like 10 out a 100 in a batch

Even if a short period be enough to stuff it. the oil line to check it was done after the turbo was rooted, to see if thats why it died and it was getting oil, so it broke down with plenty of oil, they are rubbish Clay

well, some BIG China turbos might last for a little bit as it doesn't spin that quick, the tolerance of the actual turbo while spinning should be less then a thou to stay true at 130,000RPM, most of the CN turbos are around 5~10 thous. but if its not spinning to a point of vibration it will still stay true, so as long as its not really off and not pushed with high boost it should be sort of ok. But small T25/T28 size china turbos are bad, will not last at all.

are the gt3540 plain bearing same as garrett? how much spool up difference would there be between that and ball bearing gt3540?

deanovlt: can you put up the dyno results for these man? im looking to buy one but not sure which one. i want it to be about 650-700hp. what rear would i get on the to4z ones. is the t66 front ones bigger than to4z. whack up the rear sizes with the hp ratings if you ended up getting them. i asked him on a email but didnt get a clear reply so i could choose correctly.

anyone got grant from proboost contact details apart from email? where is he based?

www.proboost.com.au (http://www.proboost.com.au)

yeh ive had a look at that i was hoping to get a contact number. i found his ebay store but no turbos for sale?

also interested in getting in touch with him, need a couple of turbros.

just email him. he usually replies within a day or 2
