Where can I get info about putting a b18a/b into a crx?

Here are the questions I was wondering about

What is the diff between a b18a and a b18b

does the crx si engine wire harness plug right up to the motor?

Are all B-series flywheels the same(as in same bolt pattern)?

Does the teg ecu plug into the under-dash harness?

Thanks

 

i think the b18a is off the 90-93 integras and the b18b is 94 and up(i think).
the harness doesn't plug right in but you could make it work, just got to play with it. and all the b series flywheel has the same bolt pattern. and all the obd ecu plug into obd

 

ive got a b18a1 in my crix with a b18b head.w/the 18a1 head it felt slower than when i swapped the 18b head get the b if you have a chance or get the a1 and find a b head [IMG][/IMG]
