trans & ecu question

Ive got a question. Im running a 93 teg 5spd. With a 99 gsr (b18c1) engine it. The trans is off a 91 gs. The axles are stock. The distributor is a 95 grey plug. Whats the propper ecu for this combo? p72 right? Should i go with a 99 p72 ? or a 95 obd1. (im not worried about smog inspections ive got a friend who passes me no matter what :slight_smile: )

Another question. I need to change the tranny in a few months to something a bit more friendlier to the engine performance wise. Problem is i need a cable tranny. Looking for something with short gears to run on 1/4 mile setups. What would be my ideal tranny?

95 P72. Why would you want to run an OBD2 ECU?

i dont have much info on ecu’s, want my engine running sound safe… the way it should be… so i guess that’s where the confusion set in. Thanks for the ecu help !
