sup ht,i have a 90 hb si with b18c1 wanna keep obd0 you guys thing the pr3 will be safe for my motor...as for the secondary im running a skunk2 manifold...i have searched every one recommends to convert to obd1.im sure there's some obd0 gsr's out there.

 

No there are no obd0 GSRs they started making the GSR(B17a) in 92 which is OBD1, the PR3 will run it but not very well, just get a jumper harness and obd1 ecu and dizzy, or you could chip the PR3 and get it tuned.

 

Rocket is correct. if you want to keep it obd0 you will have to chip and get it tuned.

switching to obd1 would be a great upgrade to your car. it allows for better tuning including being able to tune it, add features such as 2step and change every aspect of the ecu easily from your own laptop. sadly i don't think you can data log until obd2.

the conversion is pretty easy and inexpensive. there are also many threads on HT and the internet on doing this upgrade

 

The car will run lean and not make the power it should. Upgrade to obd1 and use the right ecu for the best power potential.

 

I'm running a jdm B18C and kept it obd0 using the PR3 ecu and a b16a dizzy, but like stated above it won't make the power it actually can. I'm looking forward converting obd1 in the future.

 

There is an obd1 pr3 (jdm) that you could use, it will still need to be chipped. I was lucky and found one from member here.

 

thanks all for the advise.

i will say obd0 pr3 runs way better than pm6...but its still not full potential....vtec comes in lil soon i think 6k would be perfect
