Hello all,
I wanted to secure my parts before I posted. I am building what I guess could be called a G21, consisting of H23A1 block and head, F20 crank and rods, and H22 Type S pistons. Displacement should be just over 2100 cc, compression around 11.5. This will be a nearly square engine with a bore of 87.635 and stroke of 88. The 1.65:1 rod ratio should be quite nice in terms of making a smoother power curve as well as help me with the high compression ratio (for a street car at least.) This wil be going into my 1992 Accord EX.

Other parts accumulated so far:
Lightweight crank pulley (a la UR)
OBX header
H22 P/S pump
ECU + TCM

I did have an idea of taking the "butterfly box," the unit with the vacuum operated butterfly for secondaries (IAB?) and adding a second one with the butterflies removed underneath the first one for longer ports and possibly more torque (hopefully.) Seems to hold more promise than a throttle body spacer does. Anyone tried this?

Thoughts/comments on the build?
