Hi, I am not a Honda guy but have worked on many in my day so I am not totally Honda illiterate. My friend has a 90 EF and he wants to swap in a Z6 for a turbo project and I said I would help him with it if its not to bad. We intend to use the P20/B000 trans and the axles from the PL3/A000. We also will get all the mounts from the donor car and the harness and the P28 ecu. The only things I need some one to help me with is will we need to do the MPFI swap? If so I won't need the resistor box due to using the Z6 injectors? And I have searched for like a day and can't seem to find an answer on the back motor/trans mount. I know I have to use the mount bracket from the d15 on the driverside and the trans mount from the donor. I also know about the cable to hydro conv, its the same thing VW guys do in MK2's with VR6 swaps. I also know it will need a OBD0 to OBD1 conv aswell. If anyone can help me out with what I am missing or has a good build thread that would be great. I just want to make sure we are on the right track.
Thanks, Dan

 

just get a jumper harness, 4 wire o2 and knock sensor if applicable. when u get the ecu jumper it will have all the instructions with it. i found a lil talk about the subject here: http://www.d-series.org/forums/engin...odb0-obd1.html
and here

Ok then, sounds like the best best is to go with the jumper harness. What about this back mount jazz, do I have to bust out the welder?

 

naa. just use the l bracket if ur using a hydro tranny. cuz the z6 motor doesnt use the front mount . heres another link. its for b series but its all the same hydro trans info: http://hondaswap.com/hybrid-ed-ef-da...info-ef-50719/

 

the z6 is very easy to swap in. no resistor box when using z6 injectors. n also you need to be mpfi before you start this swap haha. if u got any really specific questions ask. i did this swap in one of my crxs a while ago.

 

Ok guys thanks a bunch. I know this subject has been covered before, I just wanted to hear it from someone who did it.

 

Oh and long live the EF, the "WAR DOOR".

 

Ok, so if you don't use the resistor box you just tie all the ground together?
I mean positives together.

 

tie all the grounds to one. you dont need the resistor box cuz ur obd1 injectors.

 

Ok, thats what I thought, thanks. I found a good write up here if anyone is interested.

yeah thats not bad. me n leon just did it. you should know me. or alteast the car i did this swap in. i used to live in dalzell

 

Word, you guys still around? It would be cool to look at one before we start. We got a 94ex drop out with a Z6 complete, trans, Z6 harness, p28, axles, mounts. You may remember a guy named Gerry who has a pretty nice 98 ex sedan that is white, his 4 door is the one we are doing it to. I am avail most nights, I will PM you my number if you are interested. Should be getting started here in about two weeks when all the stuff gets here.

 

i wish i still lived in sumter, i come help u throw it in. but im up in montana in the air force now. sorry man.

 

Oh congrats, where are stationed at? I am still in aswell.

 

malmstrom i work on nukes. its pretty decent job

 

sounds dangerous and world ending in the event of an error

 

Congrats again, lots of car wrenchers in the Air Force. G/L and thanks for the help, I will post pics in a seprate thread for everyones enjoyment.
On a side note, Hows that place???
