In the somewhat near future I'm planning on doing a B18B swap in my 91 Si. I've noticed on some swaps the engine sits pretty close to the front and was wondering about fitment issues for my turbo setup? Will swapping to a smaller radiator and removing AC be enough? I've also heard talk about different cross members or mount kits to free up room. Any input is appreciated.

 

A 92-95 Civic radiator would help a little with room. I have seen setups before like this and have worked out very well. Just a suggestion, but you'll need as much room as you can possibly get.

 

Yea just use a 92-95 civic radiator. You should have enough room.
