T2 or t25
Right, stripped my turbo down and looking for a upgrade due to slight play in shafts
My question is, the t2 is slightly smaller so does that mean it will spin faster, et less lag off line?
I'm currently running t25 cold side and t2 hot,
Next q, are these the same size on the exhaust side?

turbo you have is good, my 1st turbo was an R5 T2 hot side and a Saab T25 inlet, was on boost by 1800rpm and made 200 bhp @1 bar
awesome to drive as no lag
my T34 doesn't come on boost now until 4k (but makes 400bhp at 2bar) only reason it doesn't feel laggy is with a 6 speed box

Good advice from martin there. The t2/t25 hybrid setup is an excellent choice for a road car. pratically no lag at all, and great power delivery.

Cheers guys, I think my turbo has had it, there's no end off play, in it, and some things are broken, I'm unsure on what internals mine has,
But I've found a fully returned t2,
And plan to swap my t25 hot side to it,
