i got a 91 crx si with a b16 obd0 pw0 ecu.. i personally dont like the b16 so i was thinking about selling my b16 engine or trading it for a Ls motor...how would i go about this..would i just simply swap motors and be cool. or would i need a diff ecu. thanks guys ..im really new at hondas but any help would be nice..

 

anybody????

 

you would need a new ECU as well.
the B18 is non-vtec
b16 has vtec.
mounts are the same, shift linkage is the same, axles should be the same as well...
which B18 is it? "A" I am assuming. So you shouldn't have to convert obd at all. it is a bit of a downgrade though... just buy the B18 block, and do LS/Vtec.

 

yep. an obd0 pr4. make sure its obd0 because their are obd1 pr4's.

not a bad choice going with the ls. not as rev happy as the b16, but definately more low end grunt.

It's all in the thread, just keep your b16s trans and enjoy

Both are B series motors and swap is the same, you'll have to either let it hang or cut it since you'll have a vtec wire with no use.

 

You don't like VTEC?
