Turbo Help T3/t4

[krayzie32]

I have come to possess a Genuine Garrett Ball Bearing T3/T4 or so im told.

Basically I want to determine exact specs of the turbo so I know what I'm dealing with and what I can achieve with it...

It has has a larger compressor housing than exhaust housing.

The comp cover is a GARRETT cast item And has "GARRETT A/R .50" casting

There is no cartridge ID plate what so ever.

And the exhaust housing has markings that I don't understand...

Here is a pic.

Sorry bout the newbie questions I'll measure the wheel diameters when I get a chance and post that info up as well to help determine size and capabilities of the said turbo

The turbo only made 210rwkw Which is strange for something that is physically much larger than the stock turbo but with good response (I think) I'm no expert.

as far as i know.. it doesnt really mean anything...

t3 and t4 are both different sizes of manifold to turbo flange

i think its one of those things that has just evolved over the years to not mean much and people who dont have a clue just go "awww cool"

a bit like a stage 4 turbo, with a stage 2 intercooler accompanied by a stage 3 intake!

i could be wrong, but its what ive been led to believe

This is called a Garrett TB34. Running a small trimed (48T?) 76mm comp wheel in .58 turbine housing. Sleeve bearing

[paulr33]

why buy it and then check?

i know it doesnt help but it's madness and pure stupidity

its like buying a car with no pre-prior inspection or mechnical check

or imagine buying a house without looking inside it, building checks, land precheck etc

its prue madness

don't fork over your hard earned cash on bogus and bullshit turbochargers

do your research first and then if it proves to be good, buy it to your hearts content

does it even have garrett plastered on the compresor cover ?

and it looks like the main reason it only made 210kw is extremely poor boost control

[r33canada]

yea i would agree, look at the sheet. it suddenly boosts to like 18 and then dies slowly from there and by time your in the top end your sitting at 12psi and the power line reflects that.

actually i didn't pay for it, I looked at it took photos and asked some knowledgeable people on the forums some simple question, wasn't satisfied had it inspected by Garrett only for them to confirm that it is a genuine GARRETT TB34 Turbo, genuine cast covers front an rear genuine garrent sleeve bearing cartridge .50 comp .58 turbine forgot the trim they're on a spec sheet in the car, in perfect as new condition, comes complete with dump/front pipe/intake pipe/braided oil line/water lines to bolt straight onto my car for only $300 dollars guess what I forked over my hard earned cash cos it is a bargain. Thanks for the advice tho

wow thanks for pointing that out guys. I don't quite understand dynographs as I've never been shown. I do know peak power and the powerline didn't know that was boostline, would you say this is laggy considering it's only capable of alittle over 300rwhp???

Laggy?Not at all. To make full boost by 82kmph in 4th is awesome.Perfect turbo for the street.If you sort out your boost dropping off at high rpm you will have the perfect street turbo in my opinion!
