Engine starts right up and idles fine, but is gutless when I try to drive it. It will accelerate, but much more slowly than my N/A Rabbit. I'm still using the ACN gasser trans which is geared a little tall but even still, I can tell it's a engine power issue. Even at high RPM I can hear the turbo spool but still only slight acceleration. Clutch is not slipping, if I floor it RPMs rise slowly with speed. Brakes are not dragging, car coasts just fine with clutch in.
No noticeable smoke from exhaust. No exhaust installed yet, just the turbo outlet elbow.
Head gasket doesn't seem blown. I used head studs and there is no unusual pressure in coolant bottle.
Possibilities:
- Need to install exhaust (I don't think so)
Shop didn't rebuild my IP properly (might need fuel screw turned up)
I did the valve clearances wrong (even though I went to thinner shims?)
Valves/seats are worn out and not sealing (even though the engine starts like a champ?)
Maybe I didn't time it right (I have done my Rabbit before though with good results)
Other: ???
