I have a 91 Civic DX with a DPFI D15B2 and I plan on swapping a D15 vtec in soon. I need to know what all I'll be changing for the swap. For example, are the axles, motor mounts, etc. interchangable? I'll be getting everything in this link including the tranny and ecu. http://www.hmotorsonline.com/s...30019 I realize I'll be doing some wiring but I need to know what other parts I'm going to need as well. Any help would be appreciated.

 

Its a VERY easy swap if your good with SIMPLE wiring.

First convert to MPFI and there are 100's of write ups....

Then convert to OBD 1 and run a P28. I spent a little over 2 days getting it to run on OBD 0 and I didnt like it, cutting up the dizzy and all that **** isnt fun.

All mounts line up except the T- Belt side. You have to us the D15B2 mount(I belive, I used the D16A6 mount and had to shave mine down, you wont tell until you bolt it to the engine and see the clearance) and shave it down to give more room for the timing belt. Axels will work and linkage will work. Its just a good bit or wiring.

 

Ok. I'll be doing DPFI to MPFI and then OBDO to OBD1 and maybe shaving some off the t-belt side mount. Other than that I should be good? Thanks for the help.

 

Yah just switch your d15b2 driver side mount onto your d15b, and it should fit right in, dont shave anything.

 

Ok, so the factory replacement axles and mounts for a 91 civic with a D15B2 should all work on the D15B? So it's just going to drop right in and then I need to wire everything up? The reason I need to know is beacuse the motor doesn't come with axles or mounts. I don't guess I was too clear at first. Thanks for the info guys.

 

d15b2 axles work, it drops in ( after switching mounts), wire it up and doneee.

 

no one mentioned he cant use the transmission, as the transmission is a hydraulic trans..

 

yeah, the hydro tranny will not work

either use the dx or get a crx si tranny for ~200

 

Technically he could if he got a converter.

Tell me more about this converter if you will.

 

Ok, this is what I've found out so far. Tell me if any of this is wrong or if I'm forgetting anything. If I get everything in the link above I can use D15B2 axles and motor mounts. I'll have to convert from DPFI to MPFI and then from OBDO to OBD1. If I want to use the hydro tranny Í can get this kit http://innovativemounts.com/Sh...41000. What tranny mount should I use? I can't use the stock cable tranny mount for this hydro tranny can I? Thanks again for all the help guys.

 

no input on this one?

 

sell the hydro tranny and use the money to get a good condition crx si tranny

 

I thought you were staying cable, Why don't you stay cable?

 

I just bought a jumper harness when I did this swap in my '89 CRX DX. Plug and play.

And just like it was said (up there^^ somewhere),
you will need to use your own d/s engine mount

 

you can just use your DX tranny if you want

 

Looks like I will be staying cable. Won't be using my DX tranny though, it's an automatic that's about to take a poopie. Thanks alot for all of the information guys.

 

Cable trannys are so much cheaper, im getting my si tranny this weekend with shift linkage for 50 buxxx
