i just bought a 90 crx and it has a d15b2 block but has a z6 vtec head on it. the vtec is not hooked up. the motor seams to run well runs a little rich though. my ? is will running without the vtec hurt the motor or anything. also it has a ecu from a 91 crx si. i am new to hondas so be kind to a new honda guy

 

it isn't optimal, but it won't hurt anything.

If you want it to run well, you should get a p28 or equivalent ecu and hook up vtec, the 4wire o2, and get a z6 distributor, and you will notice a big difference..

 

i know it does not have the origianal distributor. i think its a t0-2.
what distributor came on the z6. also will i need an engine harness for the p28 ecu. sorry for the noob ? but like i said i am new to the hondas.
thanks again for the help.

 

anyone else have any suggestions.

 

the TD-02u distributor is the stock 88-91 si distributor from a D16A6 (1.6L non vtec) motor. yes you will need a jumper harness to plug the P28 ecu in, and for an obd1 D16Z6 head the correct distributor to use will be a TD-42U you will also need to re-pin your current engine harness to plug into the new distributor.

 

thanks alot.

 

I didnt think the A6 dist. would fit on the Z6 head right...as in the adjustment is way off and you need to cut one of the mounting "ears"?

 

i believe you do cut one

 

yeah the obdo dist needs to be modded.

just so there is no confusion, you need a obd0-obd1 jumper, a p28 ecu for manual trans prefferably, the z6 dist, 4 wire o2, heres the link for the dist wiring you will have to repin:https://honda-tech.com/forums/honda-crx-ef-civic-1988-1991-3/obd0-obd1-distributor-wiring-1349052/ , and that should be all..
