Just looking for some advice on exhaust housing and wheel selection for a ta45 based turbo with a t76 front wheel. The current exhaust wheel is the 69 trim (2.68/3.23), I'm not sure if this is big enough or not?

The motor is internally stock, though I plan on porting in the future. I will be running around 1bar boost, mostly street driving, with better fuel and a bit more boost for circuit work. Hoping to have power by 4500rpm.

Any advice is much appreciated!

cheers,

Rob.
