I'm getting a 92 b18a a/t complete swap from my buddy for free and the only thing i'm paying for is for the ys1 m/t tranny. do i have to change the flywheel or is it the same?

I hear that for the swap u need to convert from dpfi to mpfi. but i have a 90 civic si hatch and i think is mpfi. So what do i need to do? Someone told me that all i need is the ecu jumper from obd0-obd1 and that should work. I want to do it right so please let me know.....thanks

 

you do have to change the fly wheel to a m/t ( make sure you get the 6 bolts out of the m/t fly wheel because you have to use those ). no need to convert to mp.......you have a si car which is already mp. and yes you do need jumpers to run an obd-1 engine. you need the dizzy jumper and a ecu jumper. another factor is......your injectors. obd-1 has saturated. you need peak and holds. commonly found in obd-0 b-series cars. ( 90 and 91 teggy or 90 model prelude ). i have this exact set up in my crx si.

 

thanks
