    I am going to do the swap. I have a 90 Ls integra and a 89 Si civic hb. i want to put the b18a1 into the civic. i want to use the motor,tranny,ecu,short shifter,and thr rear disc breaks. i have found out that i need to beat a spot on the side for the alt. and the lip by the back motor mount. ineed to know if i can use the wiring harness out of the Si or will i need the Ls harness:confused:. is there a cheaper motor mount than $400. that i can use, more of a stock mounts for now:confused:. any other info would be great if i am missin anything.. thanks

    you will use the harness from the civic,and you will probably need to cut or bang the front mount bracket off the front crossmember..
    as for mounts..i using ebay conversion mounts and they are holding up just fine

    I found a set on Craigslist for really cheap. Some guy was cleaning out his garage and found them labeled "EF B Swap". Posted them for sale for $100 brand new. His son was pissed when he found out that he sold them.
