1.8bp vs 1.8bp-z3 for boost
 

I have picked up an NA6 with a 1.8 for my NB2 vvt
my goal is to build one of the engine for boost as the other os in the car.

How dumb am I? Any big red flag.

Would you keep the na 1.8bp engine or the nb 1.8bp-z3 vtt

The 1.8bp did came with a speedy ecu.

Im a supper fab/mecanic guy but have zero tuning experience.
