i been thinking of so many swaps for my 91 hb. beefing up a zc, b16a, but now i'm leaning towards a frankstein b16/b20.
i want to know how this set-up is thought about by others. a good to go with and how is it with thenbasic bolt-ons

 

[:'(] unreliable, leaks fluids, and isnt strong enough for much good power over the basic headswap. the cylinder walls are too thin for boost or high compression, and the block isnt made to handle revving to 8k very many times. its great power, but for any length of time, its not very feasible.

 

best bet is the b16 swap its a obd0 the swap is all included with the package and the only thing you might have problems with is the wiring and the v-tec thang. but you well have a warranty on the motor soo its all good. zc is also good but your going to need the integra ecu and also some wiring.

 

Not true and the cyl walls are not the problem it is the rod/stroke ratio.Noobs put B20's in their cars thinking they can rev them like a B16 which you cant.The cyl walls are only 3mm bigger than a B18B and to put that into perspective you go past that when you bore a engine .40 over which alot of people do when re-building-slightly building the bottom end.All the "B20 bottom end" crap is exactly that crap.People dont take into consideration that when dealing with a different engine you have to treat/build/drive it differently.
