Can some one explain the diffrance between these two turbos. Size of housings and so on.

A T3 isn't just a T3, and that goes for a T34 also.

What...? that doesnt really explain does it.

Now see now what i mean could it be explained better maybe. A T3 of a 2wd drive i know is not the same as a 4wd. Whats the difference between the two. Then what is the difference between both these two and the T34/T35....

A T3 sits roughly in the middle of the T series of Garrett turbos - T2, T3 and T4.

The T4 is a whole size bigger than a T3, and a T3 is a whole size bigger than a T2.

A T34 is a compromise between the top-end power of the T4, and the (relatively) low-lag T3, ie, a hybrid of a T3 and T4, hence T34. A T34 is basically (for the sake of argument) a T4 at the front, and a T3 at the back, so you get the top end power of a T4 but without the low-end lag of a T4.

Hope this helps a bit.

What about my T38?

New Thread....
Has a t34 the compressure side of a t4. Not sure about that. Would i be right to think that the exhaust side of a t3 is the same as a t34 in basic trim.......would that be a .48 trim maybe????????????????.................. I know its a bottomless pit this one but something i wont get my head round til someone bangs the nail on the head.

As no-one's corrected me yet I must be right for a change

A T34 generally comes in three flavours: .48, .55, and .63. The .48 is basically the same turbine housing as the back of a standard Cosworth T3 turbo. It also gives you the least lag, but top end power is better with the bigger .63 and .55 ones..

I don't know if the front is exactly the same as a T4, but I'm sure it's different. Hopefully someone else will chip in with a better answer for you.

T3 is pointless as a 34 of any description will be very responsive, t3's re for bufty's and girl's, Not much help am i

T34 is large turbo escort size NOT T4, the T3 compressor housing can be machined out to accept the T34 trim wheel, and can use the .48, .55, .63, housing as needed/wanted.
The actual CORE(bearing housing) is the same on T3/T34/T4.

As always Tabz helpfull. So the core of all 'T3' turbos are the same......?.....
Is a t34/5 a mix of a .48+ exhaust housing t3 core and machined t3 compressure housinng..... WHAT WHEEL THEN IS USED. Ie maybe t4.....

An original T34 is a T04b compressor with a T03 turbine.. it's a hybrid.

i have just put a T34 with a .63 on the van seems ok but not fully tested yet
