Yeah that's what I thought too ::) I do know that at tdc the valves will open about halfway before hitting the piston. I found that out from adjusting the clearance and trying to push the lifters down with the crank at tdc ::)
I don't know what else to check next.......maybe see if the wheels are sticking into the housings enough or something. ::)

'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.

obviously you have a problem with you turbo. unfortunate that you spent alot of money without doing your research first. fortunately you have your oil and air/exhaust plumbing sorted. why not try a different turbo vnt or otherwise to get your boost on say a junkyard turbo? contact prothe about your incompatibility issue.

well what ever happened here?
and what did you do about your rear, passenger's motor mount to make this thing fit?
and what about the oil drain?

Yanked the turbo, the current configuration is in my sig.

MK1's don't have that problem but either way this is the euro style vnt with the removeable manifold and it sits higher up so it would probably work fine with a MK2.

Threaded/brazed a 90 degree street (I think) pipe fitting into the oil pan and used a short chunk of hose and a flange that I made.

Some day I want to get the turbo professionally tested/repaired and try again but for now I'm doin' fine.

Where the hell am I gonna get a euro vnt?? Anyway I have a vnt I'm just gonna cut my mount I got one from the junkyard today.. Just need to figure my oil lines. An find out if a 2.0 intake manifold will work (of course not) or if a longitudinal mounted 85 fox intake will work.. Then I'm boltin on. Even if I only get 5 psi I'm only doin it for to sound mostly an hopefully a few more mpg
