i have a friend with a 1990 integra gs who just swapped in a b16a vtec motor from japan and we can't find the right ecu to do the swap. the motor is out of a 89-91 integra xsi so i'm pretty sure it's the pr3 but i can't find one anywhere from that car. So i was wondering if the pr3 from the 89-91 crx or del sol would work b/c those are the only ones i could find. right now he has the pr4 non vtec ecu if that helps. any advice or help will be appreciated.

 

yep anything from an 88-91 will work as long as it's an obd0 vtec ecu

 

i hope you didnt get the obd1 xsi engine swap because an obdo ecu is too old obd1 is a motor out of a 92-93 integra xsi, trust me i did the same swap in a 92 it was obd1

 

ya, my friend is kinda retarded and just assumed the motor was out of an xsi so i made him ask what it came out of and they said it's from like a 94 del sol so we got it all figured out. thanks for the help though
