I recently bought a 89 civic HB from the original owner and though it only has 50,000 original miles the stock D15B1 engine is way to tame for my tastes. I'm going to swap it with a B16A out of a 90 CRX, I'm an old school ford guy and have done many big block swaps, but this is my first Honda so I'd like some help from Honda guys. I have the B16A and tranny, I also have new Axles, Half shaft, Shift linkage, ECU, and motor mount kit. Is there anything that I still need or any suggestions that you all can give me on this project? As I've said this is not only my first import but my first swap that isn't an 8 cylinder so I'm hoping that you import experts can help out a import newbie. Thanks in advance for your help.

 

Thats a good swap to do alot easier than a h22 in a ef hatch I'm alot most done tho

 

^That doesn't really help him since he's doing a B16 swap.

yeah, D15b1 engine is super weak. You will also need the wiring harness for the b16a engine. They'll be different. You'll of course need the header and exhaust as well. They MIGHT fit from the CRX to the EF hatch.

 

you would have to convert the car to multi port (4 injectors). the d15b1 is dual point(2 injectors). some companies sell kits to make the conversion easier, but wiring it from scratch isnt bad. you need an injector resistor box, unless you are running high impedence injectors. you need a 90-93 integra throttle cable. pop out the metal hub dust seals from the inside of the hubs for the axles. dent the drivers side frame rail in for alternator clearance. and it sounds like you have everything else you need.
