today i got a z6 vtec head,fuel rail,injectors,intake.i also got an obd1 conversion harness.i am putting it on a 90 crx si.can any one tell me some options i might have-running my obd-0 setup-instead of obd1.i really want to use my stock distributor and stock wiring harness.i can get a vtec controller relatively cheap.any suggestions.any parts i will need.any pros and cons for the two.ANY HELP APPRECIATED.

 

well you can wire in a vtec controller and have vtec that way, or you could get a msd rpm switch from summit and set it for your vtec but then you don't get the fuel curve of a p28 or a vtec controller or the best you could convert to obd-1 and run a obd-1 distributor and injectors and a p28 ecu so you have the correct fuel curve's and timming maps for the mini-me swap i've done two mini me one obd-0 and one od-1 and the obd-1 is so much better. pm if you need more info

 

I do swaps all the time
The easyest thing to do is leave the obdo in the car
All you need to do is find a 88-89integra ecu and you get the fuel curve you need
and it redlines at 7800rpm just like the p28
Thats my 2 cents

 

obd-1 is much better then obd-0 pm KENJI an he will make you a jumper

 

ok-i can get an integra 89 ecu-but are you sure that it will work with a z6 head{vtec}i dont really want to use a vtec controller i would rather have every thing as close to stock as possible.just to catch every body up:i have a 90 crx si.i am putting a z6 vtec head from a 95 ex on the crx.at this point i dont even want to havethe vtec controller as an option.as many combinations that you guys have used,and the parts you did it with would be MUCH appriectiated-also anyone that has ever used those integra ecu'slet me know how they worked.thanks guys.

 

I say just keep it obd0 and get your si ecu reprogrammed by zydne or just get a integra ecu like crix said

 

i would love to keep it obd0.okay-please tell me:1.what year integra ecu?
2.what distributer will i use?3.how will i control the vtec?

 

#1...88-89 integra 5speed ecu
#2...crx distributer
#3...M.S.D rpm activated switch & 12volt relay
