What else do i need to swap this

I'd say save you money until you can afford the sir2 motor with a hydro tranny. the sir will fit no prob with your stock mounts but you will have to get a conversion kit for the tranny

plus the sir2 is more powerfull and it's obd1 so you won't have to **** with wiring as much

I just put an sir2 motor in my 92 lx and it was a snap
that is a good place to buy engines from what I've heard, I bought mine from Japan Direct (www.usedmotor.com)
they have good prices and only sell great motors, check them out and send them and e-mail or call to see if they have what you want and for how much

I would also suggest getting the LSD option, you will be very happy you did

good luck
