    im trying to take out the engine that was in this crx since it was burning 3 quarts of oil a week. thought it was time to start my swap. i want to drop in either the b18c5 b18c1 or the h22. which option is better?? and if so what do i need to buy to make this swap possible. i know i probably will need the hasport engine mount kit for B series engines. but i think i need more then that. please help!!

    Search bar is your friend. Tons of people have done B series swaps into EF's. Spend the time to look for it.

    define "better"

    the bseries is easier but the h22 will have more power..

    Don't forget K's

    For the OP--

    If you want to put a B-series in your EF, you will need a mount kit, shift linkage, motor/tranny, ECU, axels... There are a bunch of things that you will need in order for it to work...

    You forgot about all the B16's as well as the B20's

    I know the OP said the B18C1 and B18C5, but it requires all the same stuff...

    i mean i won't mind the b16B that will also give me about the same power. just wanna know which will be best overall with not so much work. i know they will all need work to be able to work just want best choice. and dont worry about AC brakets there wont be any AC in this baby haha

    oh and do you think im going to need to cut, weld, or dent anything to be able to make the engine fit in the bay? i found some page where the guy said he dent some part so the alternator would fit. i have no clue since this is my first swap u can call me a noobie at this swap stuff. dropped engines but never have swapped where i need to move mounts etc.

    Yep you do need to make a dent for alternator pulley clearance, but you shouldn't need to cut or weld anything.

    You need...

    -Engine/trans/ecu of choice
    -90-93 Integra axles
    -90-93 integra 5speed intermediate shaft
    -rywire jumper harness
    -90-93 throttle cable
    -shift linkage (hasport, innovative, avid, ebay)
    -motor mounts (hasport, innovative,avid,ebay)
    -cable tranny speed sensor
    -90-93 integra drivers side engine bracket (94+ engine brackets won't work)
    -90-93 integra rear transmission bracket, must be from a manual

    You'll need to solder the 5 wires going into your resistor box. There should be 4 red and one yellow, solder them all together, and remove the resistor box.

    You'll need to move/extend the fan switch connection from the back of the block to the side of the head.

    The maf on your crx is firewall mounted. On your new engine it will be on the top of the throttle body. just unplug the 3 pin connector from the firewall, and move it to the tb.

    And you will also want to remove the dust seals within your hubs to make clearance for your axles, otherwise they may bind up.

    If your car is lowered you will need a ctr crank pulley (aka: crank pulley with just the ribs for the alternator), or have your b-series crank pulley's a/c and p/s ribs machined off. otherwise your crank will bottom out on the traction bar making right turns, and make a nasty grinding noise.

    That should just about do it i think
