Just drop it in, nothing what so ever should need to be changed from an ls swap

btw, what do you mean you need something slower? You know a b20 is faster, right?

True, but he's already got that from the LS, he shouldn't need any more parts unless a new clutch is in order

In torque it is faster maybe? I knew about the intake manifold ill probably go with an aftermarket one anyway. I just needed to make sure so I didnt run into any problems. Thanks alot for the help!

I've got the same swap in my CRX right now. Origionally i had a B18B1 then blew the motor racing it so i bought a B20B. Its an increadibly easy swap to do, everything bolts the exact same. The only thing i had to do was switch the B18 distributer, alternator, intake manifold, and exhaust manifold, onto the B20 because the B20 is a different Obd than the B18 i had.
