LS into 91 si bay.
How hard do you think it would be to fit an LS motor into a 91 engine bay? I mean, how many motor mounts am I gunna need, can I use the A/C and Tranny mounts?? How much steel am I guna have to melt out of the firewall?? Anybody with experience installing an LS by themselves please respond. And oh yeah, can I fit a t3/t4 in there later on? How many walls do i have to bang out!!?!?

Re: LS into 91 si bay. (crxxxrc)
It is a pretty straight forward swap:
Depending on the model year of the LS you will need:
Aftermarket mount kit...Hasport, HCP, place racing,etc
Aftermarket Shift linkage
B series cable or hydraulic transmission...if you choose to use a hydraulic trans you will need to buy the conversion from hasport or build your own.
90-93 integra axles and intermediate shaft
LS ecu
That is a basic list. Try and use the search function or just peruse the ef and hybrid forums and you should find tons of info on b series into ef swaps.
