I'm looking for a COMPLETE guide on how to swap a JDM ITR engine into a '91 CRX DX. Did a search and found only scathered information. Thanks for the help.

 

First look up a DPFI to MPFI conversion.
Then look up the pin outs for your ecu your using.
Then run wires from there to your sensors on the engine.
Get b series axles and mounts, bang out room need be,hooray. your done.

Bah ha ha ha, thats laughable.

The stock wire harness will have to be cut quite a bit to either adapt the Type R system or replace the injectors etc with OBD? plugs etc that are compatible with the engine you purchase.

How about the hydro tranny thing? Lets make a decision to either keep the hydro tranny or sell the type R tranny and buy a cable tranny (less hassle, I know this as I am keeping the hydro now and it's a hassle). If you keep the hydro tranny then you need a cable/hydro tranny adapter.

What about an exhaust system, the stock or aftermarket EF system does not fit the Type R head pipe at all, much too small in diameter as well.

The front crossmember does not clear the engine so either the stock crossmember needs to be cut or an aftermarket crossmember will be needed.

The ECU you run will need to be at least V-tec capable and you will need a chip tune if it's not for a type R or equivalent. A P28 is very useful if you can find a chip to run the Type R engine or just use the JDM ECU it is ideally suited for the engine unless you have plans to do a lot of performance modifcations (in which case the P28 is the choice to make).

I'll come up with more stuff as I find them

 

simple swap....don't think to hard about it and confuse yourself. Every b-series swap is the same except the fact that you need to add a few more wires for vtec

 

O. K. Thanks guys Here is what I got so far:
1. JDM ITR engine that is OBD1
2. B series to EF shift linkage
3. '98 JDM ITR ECU, '98 USDM ITR ECU (which one to use or any can be used)
4. EF SI harness
5. Place Racing X member
Can you add parts that I need to this list? Please be as precise as posible. Thanks

then why do you have obd2 ecus?
sell the si harness to me cause you gota rewire your dx harness for mpfi you cant use the si harness in your dx. you also need axles hoses and an obd conversion harness

 

O.K. Since I would like to keep the hydro tranny and OBD1, Which OBD1 ECU and what kind of chip(if needed) to use for the swap? Thanks.

 

its a farly easy swap , if you have any questions pm me , i have a 98 itr obd-1 set up in my 89 civic si

 

Amen! PM sent
