Please help me if possible this would be my first swap. please keep flaming to a minium plz. Thank you for stoping by, any pointers or links will help!!!
New Motor:
96+ jdm d15b Engine (50,xxx miles)
97ex Tranny with stage 2 Clutch
obd2 SOHC ecu

 

i dont think hydro tranny will work on that car, cable will, i own the same car and i was going to throw on an Si tranny but it was hydro so it wouldnt work without an adaptor.

 

will my d16 tranny work with the d15b motor?

 

yes but there might be certain things you need to replace, like the flywheel. Other than that all single cam trannies bolt on to all d-series motors.

 

Neat! D15b's are neat. I know several people that want to do a d15b swap out of pure principle of cost and what that lil 1.5 puts down. Good luck with it. And yeah...cable tranny. My suggestion is a ZC/Si combo. Of course...I'm kinda partial.

 

Awesome engine, I love mine... Since your OBD1 already nothing to worry about as wiring goes... u may have to swap over O2 sensors (the one that comes on the D15B is single wire, the one on the OBD1 setups is 4 wires, except the VX which is 5)...

Yes your tranny will bolt right up... Just remember if u buy a new clutch, flywheel, ect, u will need the one from the original tranny... So if u have an 88 CRX Si, and thats the tranny that u used, buy for that car...

 

y8 motors would also work

 

Wht hp do that motor put out?

 

Depending on the motor and the setup you choose it can be anywhere from a factory 80ish hp to a nice 100+ hp range.

 

The D15B VTEC (only D15 worth swapping) is rated ar 130ps (ps is the measurement used in Japan instead of HP) which is about 128 HP, just about the same as the D16Z6...
