'91 Si b18 swap info needed

what all do i need to swap an '90 LS motor into a '91 CRX SI? I can get the motor/tranny for cheap I just want to make sure it won't be too expensive to get the rest.

Lets see.. its about the same as swappin the b16 or any other b-series motor. Custom mounts (hasport, HCP , Place racing ) , shift linkage (hasport, HCP , Place racing ) , 90-93 integra axles, 90-93 integra ecu and thats about it. Oh you need the intermediate shaft if the motor doesn't come with one.

also, keep your Si harness, and plug that into the ls engine. Its all plug and play with the 90-91 LS's. If you can get the teg linkage, you just need to shorten it a little bit, its not really necessary to spend 200 on custom linkage. get your measurement, and take it to a welding shop, its like five minutes of work.

a friend of mine can customize the shift linkage for free, and i've got the hookup for polyuerethane (sp?) mounts for $195.
