Default 91 CRX/D16Z6 swap questions

I have a d16z6, should i go with obd1 injectors or stay obd0? I have the entire swap;ecu, full uncut harness, axles, fully complete motor, and transmission.
Also, i forgot to grab my engine mount bracket of my obd0 motor, so does anyone know where i can find one?
Last question, can a clutch from a hydraulic clutch work with a cable clutch setup?

If you went with OBD1 injectors you have to change you injector clips. When I did my mini-me swap a longtime ago with the z6 head, i used my OBD0 injectors. I did however purchase a OBD0 to OBD1 conversion with a vtec subharness. ( http://www.rywire.com/catalog/obd0-m...kage-p-69.html) Everything was plug and play. If you want to use the hydro d series transmission you'll need a cable to hydro conversion ( http://www.jhpusa.com/store/pc/viewP...?idproduct=522 ). But be warned that the cable will stretch over time and eventually you will not be able to tighten it. I myself will be buying Hush22 hyrdo conversion ( http://hushperformance.bigcartel.com...o-bracket-only) to eliminate the cable all together. As far as that rear bracket goes, Id start checking the junkyard or HT market place. Hope this info helps.

i would go obd1 there is a lot more tuning options available for obd1 than obd0...as far as a new engine mount bracket im not sure but ebay never fails..and no i dont believe a hydraulic clutch will work in a cable tranny im pretty sure there is a different spline count when you put it in it looks like it fits but it will be loose..somebody correct me if im wrong though

Does not matter which injectors you use as long as the flow rates are the same (unless you are getting a tune).

Throw out the harness except for the plugs you need to convert your harness.
Throw out the axles and transmission unless you are going to do a hydraulic clutch conversion.

Clutch and pressure plate are the same from 1990~2000.
Throw-out bearing is not.

I already have the obd1 conversion harness.
So then, once i get my hondata, i should convert my injectors to obd1?

No need to convert your injectors if the flow rate is the same.
That's up to you to run with or without an injector resistor box (depends on your injectors).

don't believe there is a difference in the injectors unless one is not stock injectors, so stick with stock so you don't have to re-wire. can find both aftermarket easily

only oddball d series trans is the 88 that had one spline less, can use the same plate but the disk its self wont work, and also the throw outs change from cable to hydraulic.

if you have a cable tranny go ahead and use it unless you have a better hydraulic such as a DX cable and a SI hydraulic. theres conversion kits online so you don't have to run an actual hydraulic clutch pedal.

axel's are the same, if your are good use em, or if the new ones are autozone those idiots will exchange em for new ones (lifetime warranty)

if your dropping into an already mpfi car the only thing you need are the plugs from the obd1 harness that the obd0 don't have such as 4-wire 02 sensor, knock, vtec, ect.. jumper harness should have wires to hook them up to...

is your CRX a DX? if so you might as well go with obd1 injectors because you wont have a resistor box anyway.

Injectors are not obd specific. There are no obd1 injectors, or obd0 injectors.

Injectors are either low impedance, and require the resistor box; or high impedance, and do not require the resistor box.

As far as the transmission goes, you need to convert the cable clutch system to hydraulic if you want to use the hydraulic tranny.

correct

and if he is a dpfi car it would be best to go ahead with no resistor box, correct?

mpfi could easily stay low imp.

I say use the better geared transmission as the conversion kits are bolt on and pretty easy to install.

I'd say so. No point in adding something that wasn't originally there, you're just adding to the wiring job that way.

I think alot of the injector confusion simply stems from the fact that they pretty much switched to the high impedance injectors when they went to OBD1, thus everyone thinks the injectors are OBD1.

yea, there really isn't an advantage to either unless your building a performance engine where as it can be hard to find injectors to work depending if your high or low.

No, I have an HF. I have a build thread but no one was paying attention to it so i created another thread for questions.
So yall are saying that i can run the STOCK injectors from an obd1 z6 on that motor(the z6) and eliminate the resistor box?
Also, for some reason my back motor mount bracket from the hf will not go on.

yes you can run the Z6 injectors without the box but if you already have the box wired being a hf run the older ones, they are the same size and you wont have to rewire anything.

which transmission did you use? cable or hydraulic?

if its the trany that you pulled out it should fit. lol... try putting the 3 bolts in before the long one in the back, then rock it and pry to get it and be careful because those 3 crossthread easy

Ok. Figured it out. The part of the bracket that the mount actually bolts to was slightly bent. So i pondered for a little bit on what i could use (all i have is a basic 3/8ths wratchet set, a light bulb, a scissor jack, and a low profile 2.5 ton jack. Figured out the bracket would fit in between the low pro jack, pumped it a couple of times and BAM! Straightened it back out.
Went to try to put the bracket on and SHWING! Went right into place. mcguyver'ed (no idea how to spell his name) this s*** like a boss.

Now lets see if thing thing'll run!

I might have the wrong distributor because with mine, the holes dont match up the way its supposed to go. I did fix the firing order and its still a no go...
