i got a 93 hatch which had a 2000 gsr with obd1 ecu. hydrolocked the motor and now have stock b20 with gsr tranny. trying to find out what type ecu i can use on the b20 with the wiring harness from the gsr bcause i need to go thru inspection and get the vtech code off.. and also what type of cheap exhaust does anyone recomend i need to get this thing thru inspection asap

How about the stock crv ecu?

Cheap exhaust = muffler shop.

The crv is automatic it wont work. Get a chipped p28 and run a basemap or tune.

ive got a b20 hatch and the ls ecu is hands down the best out there for a oem ecu. theres been a few articles on b20 chips, but the general idea is that unless its going to be dyno'd b20 chips dont really work all too well

x2 chip the p28, but i would put the gsr head on that block first...

id still run a p75 for a obd1 ls

if i put the head on there i dont know how reliable and id have to waste time gettin it sleeved and gettin the head worked on. i just need a reliable car for now till i get more money to rework everything..

If you are keeping the block stock and just swapping on a vtec head you dont have to sleeve the motor. Just check out this thread its for an LS/Vtec but with a B20 it the same idea. https://honda-tech.com/zerothread/1676914
