1. i've got an 89 civic HB and i'm looking at dropping in a B18 modified in the fact that i want to machine it out and sleeve it so that it will be a rock solid 2.0L but i was wondering if the B18 twin cam head would still work on the new B20ish motor, and if not what suggestions u would have for a head for the cherry block ?

2. what would be the best compression ratio to mate a T4 turbo to the said engine and what piston/rod/CC combo would be the best for achieving that ratio ?

3. what's the most comon way of removing/reparing the common rust area behind the rear wheels ?

 

1. b20 head or your choice of vtec head deshrouded to your bore diameter.

2.the best compression ratio is the highest one possible without detonation. many things factor into this, but piston crowns that mirror the chamber, leave no places for fuel pockets to be trapped, have smooth radiused edges for ease of flame travel and bias the combustion event to the exhaust side are your greatest preventionary measures. other than that, its air/fuel ratio, ignition timing and intake air thermal management.

3. good question.
