http://www.jspecautosports.com/catal...od_id=723there is a b61a for u....but when u always swap motors that is a SOHC to a DOHC u usually have to upgrade the radiator ....i would suggest 1 from a DOHC del sol they will work pretty good for uhttp://www.jspecautosports.com/catal...?cat_id=103but if u want to upgrade the motor mounts anyways u might as well go with a b81c engine but a bit more in price so look at that site it has all the motors that imports make that way u can compare them and fig out what u want because im not sure how much u want to spend on the motor and upgrades if u plan on to upgrade stuff later on
