Drivetrain


Last updated November 6, 2003


I went with a VW ABA block for a couple reasons. Mainly, because it keeps a nice rod/stroke ratio.
The 1.8T runs a 1.67:1 R/S ratio (good), A 2.0 crank in a 1.8T block has a 1.55 R/S ratio (bad), and the ABA 2.0 runs a 1.71 R/S ratio (good)

The early ABA blocks come with a forged crank and oil squirters.

The 20V head is not a straight bolt-on, the 20V head has 5 oil returns on one side, but the ABA block only has 2, so 3 returns have to be blocked.
The pistons will have to be replaced to accomodate the 5th valve and give the proper compression ratio.
