How hard is the swap? Is converting from DPFI-MPFI hard? What axles can I use? Shift Linkage? Do I also need a new intake maniflod?
Does anyone know how high I can rev the stock block/head with Zdyne SECU? I dont konw if I want to go CRVTEC or just put the B20 in and use that. Ive herd of civics running 13.9s with/o VTEC with IHE. What is the r/s ratio with the VTEC head? Is it anybetter then the LSVTEC? I cant decide weather to B16 or B20 or B20 VTEC. Later plans are to go turbo w/ 450ccs and 225lph fuel pump and fpr. Anyone have any experiences w/ this swap into a rex? i prolly sound like a friggin newbie but I just cant find that much information about this swap and how hard it is. CRVTEC.com helped a bit, I cant afford to build my engine up.
Thanks for the help. Blaze

 

hey that's cool if your a newbi or not. I was also thinking about doing the same thing........getting b20 w/o the vtec. Well if you have an SI that comes with sports injection or whatever the most simplest way to drop in a B20 iscorrect me if i'm wrong)
L-longblock B20b or z
any Bseries cable tranny(LS if you going turbo or 92-93 GSR for all motor)
hasport mounts
hasport shiftlinkage
90-91 Integra:
Axles
ECU
fuel rail with injectors
distubutor
altenator with belt
and a FPR set at 42-43psi or S-AFC and tune it....it will run way better with
the S-AFC. Next thing is USE SEARCH.......look under B20, the important thing is that you try BOTH archived and recent topics, i know theres probably atleast 40 ot more post about the B20. Also i would try to instant message beatdown88hf. He has a CRX hf that he just put in a B20 and should be able to help you out.

 

I just finished putting a built CRVTEC into my 88 Si. IM me if you have any specific questions.
