ok im thinking of swapping out my aging b18a and thinking of dropping in the b20z
but i have a few questions
first what ecu do i use
can i still use the ls ecu
also the b20z is obd-2
is there a way to keep it obd-1
last im planning to make it crv-tec what ecu should i use then
thanks
Yes you can reuse your LS ECU.
B20Z is OBDII but you can use your old IM (with injectors and sensors) and your old distributor to make it OBDI.
Dunno about the CR-VTEC sorry.
there is actually 1 more thing that i forgot to mention to Ziggy this weekend…If you are running 90-91 integra (or non obd ) you will have to get a obd1 thermostat cover…On our cars this is attached to the back of the block but on the b20z it is attached to the thermostat cover…If this is not done the fan will not turn on unless you want to just connect it directly but then your fan will be on all the time and that is not really needed either…This connector is $31.82 from the dealer…
