Need a little help with a friends swap?

I am helping with a swap I need to know the best way to go about this its a 90 crx dx. I need to do the mpfi got that already down. its a 97 hx motor (don't ask) that's going into the dx. Can I use an obd1 conversion with p28 ecu and z6 intake or is there going to be a problem with the obd1 distributor on the obd2 head and will VTEC still engage or would it be easier to go with the obd2 conversion. I know obd1 is the best way to go when doing a conversion just for the fact of the p28 ecu. thanks for the help. I think I can just need another opinion

The z6 distributor won't work, it's the odd ball distributor. You can however use one from a D15B7 or B8 ('92-'95 LX/DX or CX). The P28 ecu isn't going to work either. Since the D16Y5 is a VTEC-E engine, the vtec engagement is somewhere between 2000-3000 rpms. Before then, it only runs off of 1 intake valve per cylinder. With the P28, (I'm not sure but this is an educated guess) it will probably run off the 1 intake valve up until vtec engagement (somewhere around 5000 rpms), at which point it will run off of all the valves. That will result in a very slow car, that will run incredibly rich up until vtec engagement. So rich that it will not only run poorly because of the 1 intake valve thing, but also from being far too rich (bogging bad).



You could try using the correct ecu for the Y5 (the P2N), but you'll run into some issues there as well. You'll need to run a 5-wire O2 sensor, as well as wire up the EGR. So you'll be doing the DPFI to MPFI conversion, OBD0 to OBD2A conversion harness for the ECU, adding wires for misc sensors, and dealing with the other different OBD parts (injectors, distributor, alternator).



It's certainly not an easy swap, that's for sure. If you tackle this project and succeed, you certainly have my respect. Personally I wouldn't have the patience to deal with it, or I'd charge a hefty fee to do it.Need a little help with a friends swap?
You might have take into consideration that the newer D series engines are hydraulic actuated while the older engines in the CRX aren't. They're run by cable instead. Its been a while since I messed with Hondas so your best bet is to check around Honda-Tech.com for some answers. You may be able to get away by just using the tranny from the CRX engine. Refer to a manual if you need help on swapping the engine out:

phong k is right about honda tech but i did swap with my eg from the d17 to ab18b which uses an obd2 and the d17 uses the obd1 i used the obd2 conversion. and in your case i would say use the conversion because your difficulties with the ecu will be easier to deal with down the road then using the obd1. and no i dont believe v-tech will work either
If you are doing all that work. why don't you get a b series it will go faster than a any D series in stock
