Cool, you've got experience with this. Let's see what we've got.

Yes, the pistons are indeed Duralite. And, er, they're full floating. May have had some machine work done to make that happen. I don't think there would have been anything wrong with using interference pins but here these are in all their full floating glory. Held 'em up against my old ipd 2200cc pistons and they're very nearly the same size.

As for the "too short" part: you mean the distance from the pin to the top of the piston is too small, right? Gotta watch for that. It is nice that it's too short rather than too tall, though, as normally you worry about CR being too high when boring it out... anyway, thanks for the warning, I'll pay attention to this and deck and/or choose head gasket to get the CR I want. Which is currently, um, undecided, because I might or might not want to try using a blower... yiminy, this is getting complicated.

I guess choosing a CR is the next thing to do, isn't it. Blower, or no. Gotta choose. Or I could just build it at 8.7:1 and it would run okay whether lightly boosted or not.

The big problem with using a blower is, well, then I've got to upgrade everything else.

The B20F head is nicely ported and polished with big valves and double springs... it was more than sufficient for the 2.2. Don't know how much more I can expect to get out of it, but remember, I WANT a low-revving motor. Performance increases above 5000 rpm will never matter. Wanks are hot.

Exhaust? It's a decent 2.5" exhaust, with a Clifford header that I've always regretted buying.

M41 from 123gt, has D-type overdrive. Not exactly the beefiest OD unit, but it survived my last 2.2!

Stock driveline. Yes, it's the smallest one.

Naturally, I'm thinking that a forced-induction 2.2 would annihilate my overdrive and my driveshaft. Which would be the first to go? Is it time to do a Mythbusters special on this?

As for fuel, I've got no problem building a new system to match whatever engine gets built.
I have do two things lying around: a DGV (which can be set up well for a NA 2.2, but is probably a bad idea to use with a blower) and a k-jet system (likewise.)

Anyway, there it is. Thanks for your input. Get back to me if you can remember just how "too short" these pistons are!
