This might be a bit too late, but has anyone considered the 20B Hogan manifold? You may want to give them a buzz and see what the height difference is. I currently have a Cosmo 13B in my FD so it would only be a matter of a new oil pan for me (if I didn't want to move the steering rack). I'd rather run a Vmount IC/radiator as opposed to a front mount however.



I recently saw a Pettit-style 3 rotor take to the track and it didn't do too poorly. Single turbo T66, seemed to hold it's own in the curves. Regardless, I'm sure the handling will be more predictable and tuneable with the 3 rotor pushed back 7 inches.

I'm glad my 20b is still on the jack stands. You guys have a lot happeneing and I'd love to hear the results before I start hacking. I like the sound of the dry sump but have not done a mock set-up to take any measurements. I hate the idea of srewing around with the steering rack........I think those guys at Mazda put it where it is for a pretty good reason. Good luck!!!
