pr3 or pw0 i believe will solve your problem...

Honestly, if you ever have plans of boosting it I'd convert it to obd1 ,if you plan on uberdata like me

or if you want to stay obd0 you could pickup a ps9 ecu and run turboedit w/ 1 wire vteeek

 

I agree, pr3 pw0

 

pr3 or pw0 will run it but you should get either a adjustable FPR or some sort of AFC because of the added displacement. I would say get a SAFC so you can tune the motor later and squeeze some more power out of it.

Also the pw0 doest have a speed limiter or a knock sensor, so they are easier to use and you dont have to get it shipped to eliminate the speed governor. However they are harder to find, but there out there.

 

Honestly for the total cost of a pr3 or pw0 (they rape you for them) AND a Safc controller, You could get the obd0-&gt;1 harness ($59 bucks?) and a p06/p28 and chip it (if it is a p06, change it into a p28) and tune it completely with uberdata.

uberdata

uberdata </TD></TR></TABLE>

most definetly.

 

Or if you feel like doing some research you can just mod you PM6 or get a PS9(90-91 Civic 4dr Auto) and use TurboEdit. Last I heard 1 wire VTEC is working decently.

How do you plan on engaging vtec w/ a pm6 ecu? ...

You need a PS9 if you want to do the 1 wire vtec.

Only problem doing this is that you can only "tune" up to 7800 rpms. Yeah you can rev past that, but you're fuel/timing maps will be based off of the last colum (7800rpm)
