I don't see a reason to downgrade to a B7 if you already get good numbers with the Z6. It was only more technically economical because the M/T gear ratios for B7 motors were taller than Z6 models. SOHC VTEC combines good fuel economy and torque down low, and more power in the top end.

Thats an obd1 JDM d15b, which is a d15z1. The ECU is a p84-901 or the p07-900.
This is a 3 stage which was only obd2 I think?
