After 5 frustrating days of chasing nagging issues (engine had to come out - don't ask) the turbo is finally on the good engine and man alive it sure likes the ported '06 head and the cams! Boost at part throttle is so fast its scary. I gave it half throttle and at 20 mph the back end got loose...

Next up is to secure the charge air piping...

I'm hoping my good intake will be here in 2-3 weeks...

IGOR's evil cousin is alive...
