So I'm doing a b20 swap to my 01 integra. Before I had a b18b. The driver side mount lines up but the transmission mount doesn't neither does the back mount. I have ha sport mounts. Do I have to get new mounts for a b20?

 

Mate the B18 transmission to the B20 long block. Then you won't have to worry about motor mounts.

 

 

You should change the driver side post mount (the one that mounts to the block) to the b18 post mount.
