WOW Is that TDI or 1.9IDI? Said he used the TDI crank. I saw the back of the head and IP, but couldn't tell from what I read. Either way amazing.
EDIT: title says AAZ...I think I can figure it out from there.

Did he machine the block to clearance the tdi rods? Looks like he did. Nice build but needs some numbers besides boost.

As you already figured out, he's built an AAZ. The block had to be machined to clear the rods, and the stud girdle had to be modified to clearance the rod bolts. He did lower the compression to 20:1 by machining the stock pistons, but the high boost which did all the havoc on the old block didn't bother the previously used pumpe deuse rods at all.
The engine is almost finished now and the first stop will be the local dyno operator, once it gets 1000-2000 km on the build.
I can't wait to see the results.

So when he was running 45psi, was that on PD rods, machined pistons and 20:1 compression? Also, his new main caps.. did he machine those himself?
Anything else out of the ordinary done to keep the engine bolted together. And, of course, was it ever dyno'd? 13.5 in a Scirocco would be 250+, right?

Less than 200 is enough in lightweight mk1 with good start. I´m more intrested of trap speed, that will tell the power. And dyno of course

At blowup time, it was stock AAZ crank (undamaged), Pumpe deuse rods (undamaged) and stock 22:1 pistons.
The new main caps are shop-made and, of course, ARP fasteners throughout.
I think the trap speed wqas 114 mph.
