typed in T3 on ebay expecting to see lots of 2nd hand turbos

seem to be loads and loads of these t3/t4 hybrid things for about 150 to 250 on there

anyone used one are the any good?

or is it a case of get what u pay for?

not going on a daily driver or anything and wont ask any more than 14 psi from it???????????

i saw them too but was too scared to invest.
surely there wank
would be interested to see if anyones run them

chaffe

ive used several, on daily drivers too, got one on my sierra just now. Never ran more than 16psi boost with one, but they seem to be ok to me. Obviously you get no warranty, but then who will give you warranty on performance parts?

marky_g

thats what im thinking

im running an xs-power t04e on the 3dr, currently about 28psi lol

it still works, but then, i have only done 150 miles lol

boosts fooking hard mind.

the way i see it, if it lasts say 5k miles, its almost a consumable item likened to replacing a set of tyres at that price!

chaffe

not japanese, prehaps chinese or south american, but here it is

marky_g

thats interesting dan thats the one i just looked at hummm i rely dont no what to do now 17 is cheap!!!!!!!

need to see one rely if th'll fit onto rs turbo elbow

chaffe

i did 12,000 miles with this one on a previous car, i re-built it after that as the exhaust bearing had some play in it, but its still going strong in the sierra

chaffe

just buy one, where is the problem lol

Fudgey

lol

heres mine

can any one give me a link to one thats same as stage 2 for rs turbo? not sure how to tell which one suits my car sorry to be a pest

chaffe

yours is bigger than mine fudgey! seriously, i am a precision engineer to trade, i have had both garrett and cheap chinese turbos in bets before, and they are identical, the same size bearings, the same materials and tolerances. the only thing i would say is that they have copied a 1990's design, not a modern gt design. but they still work very well. You wouldnt think twice about putting a pattern water pump on your car so why should a pattern turbo make a difference?

COCHYN

My old RX-7 now runs on a single turbo conversion with one of these ebay turbo's, done just under 600 miles and there's a lotta play in the shaft. Decent power curve though and would probably be fine after a rebuild.

here is something that may interest you

Fudgey

iTrader: (4)

exactly mate. that and im not prepared to pay out a grand a time for a branded turbo lol

as even with warranty, 99% of the time they will say its 'oil contamination' that was the fault, not the turbo unit so still wont pay out lol.

cochyn, what boost is it running? as i doubt mine will last that long at 28psi.

so say about 19psi max if you want them to last.

but as chaffe said, just stick a set of 360 degree bearings in and you should be ok.

chaffe

yep. and the shaft, compressor wheel and nut are all neatly marked up from new so anyone can re build them back to original balanced spec

COCHYN

Its runs just short of 500bhp, so enough boost I should think

Fudgey

iTrader: (4)

exactly, treat them softly and i bet they will last for ages, screw the fuck out them and like anything, sooner or later its gonna say enough is enough!

i get awesome chatter too, no gay DV's here boys lol

so that also wont help lol

chaffe

all on an ebay turbo, thats great, love it

COCHYN

Yeah, but it is shit. Run that kinda boost on a Garrett and it would last a lot more than 600 miles. So there is a difference.

Fudgey

iTrader: (4)

still working isnt it? play or no play lol

chaffe

a difference in price, i would ask someone to try one then make up you mind, it all depends on your engines oil pressure and how you drive. some garrets have lasted a lot less

series_one_rst

looked at these and was bit sceptical. turbo technics stage3 is 550 quid is it really worth risking 20 psi through one?

COCHYN

Nah I'm not convinced, there's a lot of difference in the ebay turbo's and genuine Garrett's. The boost pressure on the RX's turbo isn't exactly staggering on a turbo that size and its only used on the road, but the play in the shaft is ridiculous now

chaffe

but an rx7 has no sump and the oil for the turbo is fed to it how? if i was you i would buy a garrett.

stevieturbo

For what application, what sort of power goals ?

SiST

iTrader: (1)

Without being funny, with the amount you spend on uprated engines (myself included) I would much rather pay that bit extra for a proper garrett GT unit (and I did). They will pay for themselves over the miles instead over chinese ebay turbos.

escoskmv

ive got a t304, its running 20 psi, pulls like a fuckin train and sounds awsome. its done 350 miles and it smokes!! there is no play in the shaft at all so im goin to get new seals fitted with 360 thrust bearing and may be roller bearings. if it costs me 300 to get it sorted its still cheeper than 1000 + for turbo in this country

series_one_rst

scrap that just clocked price plus vat!!

marky_g

duno rely 14 to 20 psi 170 to 220 bhp maximum

jus what a standard garrett t3 would do i guess

marky_g

lookin at fudgys turbo its 175 but think thats over kill for my needs

Fudgey

iTrader: (4)

if your fwd mate, you would prbably need to cut a hole in the bonnet lol.

saing that, i have a top mount manifold so it sits up high anyway.

if your local to swindon and want a quick blast to see how it goes then let me know.

its a twinscroll and is making good boost by 4k rpm starts boosting around 3500rpm and pulls fooooking hard lol. lights up the rears easily in 3rd, in the dry lol

stevieturbo

If you were prepared for a bit of fab work to fit a different unit.

A Mitsubishi TD04 from a Subaru or similar can be bought for less than Ł100 and will easily flow enough for 220bhp, and spool very well

I think some Volvo's also use a TD04 based unit, although it does use a Garrett style T3 flange

Or consider a used GT28 from some of the Jap stuff, Nissan 200's etc. I think a few other cars use them too.

Or maybe something from a VAG 1.8t ?

marky_g

ah pitty im miles away mate yer it'd never go under my bonnet unless it was over gear box mount

yer 28psi must be a right kick up the arse

glad u put a pic up now lol

marky_g

well im not lookin to do it on the cheap just happend to see the ebay ones for less than some places charge for a rebuild

anyone diy rebuilt a turbo?

Fudgey

iTrader: (4)

i rebuilt the turbo on my old 200sx mate, just bought a seal and bearing kit.

it was coked up to fook so cleaned all the crap off and it went ok.

sold it a few months later and never heard back from the buyer (someone off here) that it went wrong etc.

so long as the compressor wheel and nut goes back exactly where it came off, all is good!

chaffe

as above ^^^^^^^^^^

marky_g

humm might try it then i take more complicated stuff apart every day lol

I remember talking to a few guys on a US forum who'd used these cheap turbos on Focus engines. The general consensus was that you might get 1k out of it, and then they can start to play up. They all said to just buy one and change the bearings for decent quality ones.

Personally, I think I'd buy a good quality unit from a known manufacturer. I can see the appeal of a cheap unit, but if it shat itself in a big way and bits of it ended up rattling about in my engine, I wouldn't be best pleased

Fudgey

iTrader: (4)

IF the turbo let go, tou would possibly end up with the exhaust turbine wedged in the exhaust system somewhere so no big drama, and if the compressor wheel shat itself then most of it will get stuck in the intercooler, of course there is the possibility that some may see their way into the engine. but fairly unlikely imo

as once any wheel is detache from the shaft, it wont make any boost to blast it all through.

thats my opinion anyway
