crx_si-r

ok, im getting ready to start pieceing together the parts to convert my LS Vtec crx to obd1, i have the following in my car..
95 B18B1 bottom end
95 B16A3 head
chipped OBD0 PR3
OBD0 TD-22U distributor

if sourced the following for the conversion...
virgin P28 (auto)
virgin P28 (5 speed)
OBD2b Type R distributor

now my question is this..
is there any real difference between the distributor that i use? i was originally planning on swapping the obd2 plug for obd1 plugs and running the Type R distributor. or should i just buy a obd1 B16 distributor? i know i have to get my P28 chipped for the B series motor. other than the jumper harness would what i have so far work? thanks for the input guys. also is there any difference in performance by running a B16 dizzy over a GS-R or Type R dizzy?

Seeing as how many posts you have and are still at 100%, your probably smarter than me, but heres what i think. Use the obd1 dizzy since thats what your converting too. Also, when you get chipped its not really for a b-series, i believe its just mearly disabling the knock sensor to make it b compatable. I dont think their will be any performane gained from the use of a type-r dizzy b/c they all serve the same purpose, i dont think one puts out any more voltage than the other. However i cant say for sure.

well i know the P28 has to be re-chipped to a somewhat mimic the P30 b16 ecu and P72 GS-R ecu, but i kno it wont look for a knock sensor because the P28 doesnt look for one. but anyway is it fine to just re-pin the obd2 dizzy to obd1 plugs? thats my main concern, cuz i can do that easy. thanks again.

Correct on the p28, they just use the base maps from the p30. Im pretty sure you can re-pin the dizzy, b/c thats the main diff. between obd's on the dizzy's, i've seen a few write-ups on re-pins. So i say go for it

yea im planning on goin obd1 maybe next summer. well i think ill just make myself an adapter from obd0- obd1. i made one last year for my hatch. it was an 89 Z6 powered HB. and my obd0-0bd1 adapter worked fine. so i think i might go that route i just gotta dig up my diagram that i made myself. lol

Save you about 150 for a harness, lol.

Based on looking at the FSM's on both types of distributors, I don't see any reason why you couldn't just adapt it over. They are essentially the same design.

yea the dizzy was my main concern cuz at my job each motor has different part numbers and i was beginning to sencond guess myself. so i just gotta go to the local junkyard and and pick up some plugs. thanks guys.
