Ok I have a 90 Si hatch with a 96 Civic D16Y8 swap and it is still OBD-0 and I wanted to go go OBD-1 so i can get V-tec to come in. So what all would i need, Say what Dizzy, ECU, & Wiring. If any one could help me out it would be Great. Thanks

ECU, dizzy, conversion harness, and just wire your VTEC solenoid into your exhisting harness

 

But Which year dizzy, ECU, & where do i get the conversion harness

 

I am not 100% sure about the dizzy but you will need a P28 or P08 ecu, conversion harness, and a 4 wire oxygen sensor if you use the P28 ecu.

Thanks man,


Bump any one else?

 

92-95 OBDI dizzy, check the performance parts forum, there is someone there selling the jumper harness

 

but will the 92-95 Dizzy fit on the 96-00 head?

 

Yes, but except for the z6 distributor.

 

you could stay non OBD and just use a apexi vafc for vtec, just get it tuned on a dyno

check em out.

 

or get an RPM switch from summitracing and hook up vtec to that. you could still stay OBD0 and avoid having to pay out more $$$

the switches are like 40 bux

 

here is the info i was talking about

the rpm switch works but it's deffinatly not the best idea. You'll either be rich down low or lean up top. Not the best situation and deffinatly not maximizing the potential of the motor.

are you serious? A non-z6 d-series distributor will fit a y8 head? I hope you're right because i'm about to swap my y8 mini-me to obd-1.

 

if you stay non OBD the apexi vafc would work since you could tune the air/fuel ON A DYNO/WIDEBAND w/VTEC.

 

ok, but dyno time and a vfac is $$$ right there, just use the ecu honda intended and then mod IT later if you really want.

im not saying that way doesnt work, but not everyone has a wideband and free dyno time handy.

i dont really see any advantages of pre obd, except the cost of upgrading, which would be negated in the case of buying a bunch of **** to emulate an ecu that honda makes....

YES, I agree w/you, just another way to make it work.

 

You can use the y8 dizzy, no need to use a z6, internally the obd1/2 are the same, its basically just the plug that need to be changed out (well, theres more to it than that, ill take care of that tho!)

basically, if you go obd1, go ahead and use the y8 dizzy

 

I had the MSD RMP Switch and that was a piece of ****, it didn't do anything at allll, my MSD switch is on ebay right now for sale. but as of right now I'm using my OBD-0 90 SI Intake manifold, Dizzy, and an 89 Integra ECU. with no v-tec and it was just like the D16A6 so thats what i'm working with now! and i called Rywire and i cant ever get ahold of any one. so who knows

 

Im right here man, im the easiest person in the world to get ahold of (im always online).
Leave me a message, email, pm, whatever, ill get back with ya.
