if i have a pm6 and i want to put a b18 in my car can i just chip the ecu or do i have to get a pr4?

 

Either will work, you will probably find a 90-91 PR4 for cheaper than getting your ECU Chipped...but if you plan on going turbo or doing some serious upgrades eventually then getting a chipped ECU will benefit you down the road

 

thanks i was pretty sure but i just wanted to make sure! thanks

 

I have an obd0 PR4 for sale right now!! 40bucks shipped!

 

i have one too but i wasent sure if i needed to keep it or not.
