just wanted to double check to see if this is a direct drop in and bolt up to my 91 dx hatch back that originally had the d15b1 in it the si motor+tranny is out of my friends 91 si crx.

for sell
2- d15b1's plus 4 speed manual tranniess
many other parts from to 91 dx hatch back

 

yea the motor should drop right in, but u have to take the motor mount off your old motor and the rest should fallow. i have the same swap but im just having a problem with my tranny. let me know how ur swap goes.

 

doesn't he need a pm6 ECU?

 

i used a 91 SI ECU that seemed to work just fine.

 

91 si ecu is pm6....I'm just thinking that he needs one for his dx (wherever its from)

 

umm didnt you say D16Z6 in the title and now you wanna know about a CRX Si motor? The EX motor will bolt in with the help of the mount off your old D15 and a good old obd1 conversion or a pm6 with a vafc and odd0 the engine, w/e floats your boat.

wonderin' the same thing, unless the CRX has the z6.

Well it should drop in fine, main thing you need to worry about is wiring. You will want the mpfi (which you will need to splice your harness) and you could either run the vtec ecu or you could get a vtec controller.

actually, if you do a complete changover like i did, then you dont need to convert to mpfi, that stuff is already in the harness. Just lemme no if you wanna go about it this way, i'll let you know exactly how to do it

 

Ok sorry for typo it is d16a6. i didnt look at the engine code to check i just guessed and i got it wrong oh well.

I asked for ecu and harness and my friend said i could get that 2 so do i really need the harness? i know i need the ecu because i dont feel like going through trouble of wiring up vtec controller and doing mpfi wiring.i dont know much about electronics so i need Help!
