Hi,
Im in the middle of building a zetec turbo for my s1 and was after a t34. I came across one on ebay (or what i thought was one). Its a turbonetics turbo t04e model but was assured by the seller it was a t34. Heres the spec:
.50 A/R compressor
.63 A/R turbine
.57 compressor wheel trim
Here's some pics:

Im looking for 340 bhp when it's done, i can return the turbo if its not right.
Any help would be great
Cheers
