Hi,

You all probably get this kinda thread a zillion times but I did a search on here and didnt find anything that helped my question. Anyways I just wanted to know if this is a T34 or infact a T3? It was bought as a T34 turbo but I was told its a T3 rated 290bhp t3 from a series 2 rs turbo with a cossie exhaust housing. thats why it has a .42 compressor housing (thats the cold side)







I guess my query also is .... where it says .42 is that the a/r compressor housing if so Im sure a T34 is .60

Cheers

 

looks like a t3 to me as dont t34`s have a moulding where the actuator goes?

 

Yep looks like a t3, I have a t34 and the front is .60

Si

 

yup just been out to garage to measure my spare t34 and its 60

think you been jipped mate,sorry

 

Something doesnt look right about the exhaust housing for a T3....... yours looks bigger, the water pipe fits in a different place, and the wastegate to elbow bolts are a different config!!
My guess would be (and it is only a guess having never seen a T34) is that it's a T34 exhaust housing with a cossie (T3)compressor wheel....... although why anybody would do that i dont know..... so probably not now that i think about it some more! lol

My old T3...

 

The core(bearing housing) is identical on T3 T34 T4, with this having a AR42, it is T3 compressor size, on 2wd(4wd were larger), can't really see enough detail to work out turbine size.
It MAY be a machined out T3 housing a T34 trim wheel, as this is entirely possible(I have it).
tabetha

 

well the seller said it was a T34 hybrid....I will get more pics for you guys 2morrow. Though when the identification numbers were told to a turbo company..they said it was a 2wd sierra t34...hmmm

Thanks again for your help!
Cheers

 

So ur saying you have the same turbo? If so what engine are you using it on and do u know the bhp figures?
cheers again

 

looks like a t3 with a .48 housing on???
