This is a 25hp VW engine case that's been bumped from IIRC 1125 to 1578cc. Machined for Porsche valve train parts with Deano's reproduction Okrasa dual-port heads. I forget what the turbo is from.
What'd that get him (Darrel Vittone)? 151.4mph in the flying mile at Mojave, CA. I like the rear bumper extensions.
Also Jay Leno had a BMC Mini with a BMW motorcycle head on
a recent yesterday's episode.
