Pretty cool find.

I'm ASSUMING that's a B-Series-based engine....but that's a complete guess. He says it's a short stroke engine. I'd guess it had to be de-stroked to meet competition displacement requirements. I'll bet that thing was turning some STUPID RPM.

*Edit Too much time on my hands, this afternoon.

It might be a Mugen MF-204B that's based on the old Prelude B20. Here's a link to a car with one in it.

Correct. Plus it breathes through a 21mm restrictor. Lots of revs there. Probably 6500-7000.
