Ebay Turbo

[jattsta]

dont have a dyno chart, but when ever i get a chance. will post it up

[jattsta]

Hows the lag and day to day street driving on these ebay cheapies? Why would anyone cheap out on such a critical component as the turbo :s

yeah i understand but i honestly dont consider the turbo to be a critical component in the car.. its the other supporting mods like injectors, afm etc that will initially keep the car running healthy into greater power that compliments the turbo to perform well..

there is a bit of lag,, but i love it.. you feel the sudden power at around 3000 (full boost)

Gee I'm gonna go dig up the blitz Ecu that came with mine and sell it for a fortune as this new craze takes over.

Interested to see dyno sheets also

HAHAHAHAHAHA sig'd.

[LANDSCRIBBLE]

damn i knew i should have bought that $500 bolt on gt35 kit instead of my hypergear

general consensus has always been that its all in the turbo n tune...

also, if ur seeing full boost at 3000rpm then you have a small-arse turbo on there. infact i wouldnt put it past the chinese ebay place to have told you a stock RB25 turbo. Its pretty much the only turbo that will make full boost by 3000rpm on an RB25...

Depending on what full boost is. if its set to 10psi then its pretty average.

By the way, mate's XR6 BA fitted a ebay China core and only lasted 200kms, lol

This thread has certainly brought the lulz...

Cannot believe some of the stuff before my eyes... Backyard mechanics at it's best. Next people will be filling their tyres with grass to fix flats

Just because the turbo works doesnt mean its good. If you had a dyno graph and compared it to its equivalent size in hypergear kando garett etc. youll see its performance is shit.

Havnt you tried that?? (tee hee)

best backyard fix ive seen pics of was of a ute (in a small african country)where the owner had lost the rear tyre off the rim and replaced said tyre with a garden hose and he was driving it around like that

Except the tyre does not spin at 100,000+RPM. Or he would be sitting on the moon. lol

ive done about 20K on it since install.. it is supposedly meant to run with bigger injectors without further tune (not that mines ecu can be tuned) .. not sure about the z32 (still running a stock afm) . just have the little bolt ons, eg, big return mount ic , bosch fuel pump, series 6 sparkies, pod, 3 inch exhaust..

this chip know's when you've changed the injectors too, i wasted 'big bux' on my ecu! F!

/\ he should really do both, otherwise he'll need to improvise a new diff

[StevenCJR31]

backyarding at its best. . .

Yeah the rest of that email was pretty funny too -

[Manuel Kasko]

Bahaha

This needs to be named DIY fixes

And put in le wasteland

[headwithbeard]

so, why are these cheap turbos failing? poor manufacture, poor quality materials, user/installer neglect? do the expensive turbos really out perform the cheap ones?

just because it's cheap doesn't mean it's crap and so far the argument to buy the expensive turbo seems to be losing to me... by about $500.00

I agree, turbos are not really complex pieces of machinery.

Not all cheap turbos are bad, without even thinking Kandos and hypergears are proven performers without the price tag.

as with most things of a "cheap" nature it can be one or a mix of things you have mentioned that cause premature failure. the failure can range from oh my turbos making a funny noise to why is there no boost, right up to i think a piston just shot through the side of my block.

From what I have seen, the particularly bad ebay turbos are not balanced (or balanced at a low rpm to claim a low failure rate) - which is not a hard thing to do and is essential to ensure to the functionality and longevity of a turbo. you simply take it to a turbo shop and they attach it to a manifold in store and spin it right up to it's max rpm to ensure it spins freely and centered. if it is unbalanced they can cut small bits from the inducer or exducer to ensure it i within 0.00000 something of a gram off weight.

all the more mid range to expensive turbos will have slight bits of metal shaved off, thats not a manufacturing fault. If it is unbalanced with a cheap material or a cheap bearing, at a high rpm the fins start rubbing against the housing and anything from some of that dust getting sucked into the motor to a single fin to the entire set of blades flying off at crazy speeds can happen extremely easily.

Some other cheap exhaust housings leave large amounts of space between the exducer and the housing to mask this problem as well as other things and that causes positive boost to come on really late and gives you a useless powerband.
