I'm new to this forum and am asking for help from all. My appreciation and thanks to all of those who contribute.

I have a 91 crx dx automatic and wanting to convert to b18c.

First route: buying b18c with tranny and ecu.
If I bought this, then would I need to run a different series of wires to the ecu because I run a dx and not an si. I know that the b18c has hydraulic tranny. If I converted the pedals to manual, what hydraulic tranny appication would fit? There are aftermarket ecu plug wires, will I be needing any of those? With axles, I've been told to use 90-93 integra axles, are they direct bolt ons? With regards to the mounts, I'm told to use hasport, what other mount is needed of which I don't know of? With regards to the shift linkage, which shift linkage am I suppose to use, is there any fabrication of sort, or do they bolt right on?

Second route: buying a 94+ wrecked usdm gsr.
If I bought this, do I remove all the ecu wiring and lay in where my old ecu and its wiring went? If so, which wires do I need to splice to reconnect to my crx's old wiring, what they are, and where are they located? With regards to tranny, would the gsr's haudralic tranny application fit, and also the pedals? What else on this wrecked car do I need that I haven't mentioned?

Overall, I am mostly concerned about the wiring because I want to do a nice job and I also want to make this work. I'm new to this site and have done alot of research before attempting the project. I'd appreciate it if you include detailed instructions with photos if possible. I really appreciate all the help I can get and making this dream come true. Thanks to all of you.

 

Dude, you are asking waaaay too much out of one post.
You need to do a lot of research on this web site.
Here are a few things you need first.
Hasport B series engine mount kit with the cable to hydro convertion.
Hasport B series shift linkage.
Integra axles 90 or newer
Hasport will pretty much sell you all the wiring needed, but here is the trick.
you first need to convert from DPFI to MPFI, then add VTEC wires, then convert to OBD1 if you plan on using the GSR ECU, injectors, and distributor.

You have a lot, a lot, of work ahead of you and you need to start reading and learning what it really takes to do the job.

 

save your self time, money and a big headache and just get a 5spd conversion and a cable b16 swap. but if you want that swap that bad then good luck!

 

I have a good how to b16 swap on my site, and I am also working on a b18c how to. http://www.droppedcrxsi.com
