Ok I have Z4 fitted to my 95 JDM and wondered if a W6 would be any improvement,Im askin this as im told the W6 is the same as the Prodrive map(is this true?)
there both supposed to give approx of 260bhp,
can anyone enlighten me at all?
If its not then I will get a chip in the W6 for a remap so its not all lost.
TIA

 

No..W6 is from an early 240ps WRX.
The Prodrive equivalent is a 6K which runs similar fuel/ignition to the Z4 but with 13.6psi peak boost rather then 12.7psi
