Its a standard 3door YB. brand new .5 oversize Mahle pistons. rods and crank cleaned/checked/balanced. standard head/cams cleaned with new lifters/guides/stem seals. 500 cooler. swirlpot and oil breather. grpA breather. grpA headgasket. Dark green injectors. MSD chip to suit and MSD set up July 2011. brand new TT "sierra 2wd stage3" turbo.

Firstly, can anyone tell me what sort of power I would expect to see this run at?

What is the spec of the TT turbo. Is it a T35.68 housing??

Does the rebuild sound good enough to run current BHP safely and realiably?

What would be the next step of tune for it? Diffrent injectors/turbo/chip or what?

Also its running L1. When would this be need to be upgraded?

Thanks in advance,

Ross.
