hi guys. im collecting parts for my head swap. i was wondering if a virgin p72 would be a good enough base map to run a b20zvtec. the block is a completely stock b20z2 and the head is a completely stock gsr head with stock intake manny and cams.

 

The p72 will run the motor, however the displacement difference is going to cause the vehicle to run slightly lean. I would recommend chipping the ecu & having the car tuned for the best result.

 

absolutely. i just didnt want to rent a tow dolly to take it to the tuner. thanks.
