I was lookin for underhood shots. I have seen that one.
Hes running C heads as well. Not just your typical cut and slap together setup like mine.
As for fitting the B head 1.7, 2.1 or 2.2 under a Gen 1 hood, aint gonna happen unless you do it wrong. You have to notch the hood AND drop the k-member doun almost 1". Dropping the k-member down that much will cause MASSIVE negative camber and toe out when the suspension compresses. These cars have a fairly large camber swing as is, I wouldnt want to enhance that by screwing with the geometry.
Really on a first gen I think a centri with intercooler would be the easiest install. Twin screws are killer, I love mine, but the heat is terriable and they dont make an intercooler for B headed versions. Roadboss has the better setup and if I were to do it all over again thats what I would do, swap C heads on there.
A guy I know just got an ENTIRE 03/04 setup with intercooler, Eaton, timing cover, bridge pullys and all for $1200!

Another $300 for some 99/01 C heads and if you have the skill then you have a bad ass setup for WAY under $2000.
Will still need a cowl hood though.
