95 Eurovan Syncro Weekender TDI conversion

This is the first Syncro Eurovan we've had in our shop and is getting a highly tuned/built stage IV 1.9l AHU TDI engine, which as far as I know will make it the first 4-cyl TDI Syncro Eurovan in the US.

OK, let's get down to business

Engine build:

 AHU engine block back from machine shop.  Oil dipstick hole is drilled and three R side engine mount 10m holes are drilled/tapped, engine is blasted clean, taped, painted, and oil squirters installed.

Engine build bench: polished crank, main bearing  caps, main/rod bolts, ASV pistons, ARP head studs, etc.
 K&S main bearings installed in block, assembly lube applied.
 Main bearing caps fitted with plastigage.
 Checking main bearing radial clearances.

 ASV pistons awaiting mating to rods.
 ASV pistons mated to AHU rods.
 K&S rod bearings installed, ready for radial clearance check.

 Oil squirter close-up w/ASV piston oil galley.

  1. Very nice job. Did you change the transmission gear ratios for the diesel? Do you have any mileage data on it now?
