I've done some searching around, but haven't been able to find comparable dyno plots for these two configurations on a 2002 WRX (ie: 2L engine): AP stage 2.5 with a VF34 -OR- AP stage 2.0 with meth injection (protuned or street tuner tuned, of course).

Does anyone know how these two options compare for daily driving?

According to my research, they will produce similar hp numbers, but the meth. injection can produce more peak torque:

Stage 2.5: 315hp, 295ft-lb
Stage 2.0: 285hp, 285ft-lb (Stage 2.0 only) + maybe 30hp, 35ft-lbs with meth = 315 hp, 320ft-lb???

FYI, the Stage 2.0+meth setup runs about $500 less than the Stage 2.5 setup I would put together...

Nobody has compared these two setups before? :confused:

if i had to pick between the two for DD i would go with the more consistent, easier to tune, more reliable vf34 setup.

then add meth to that :devil:
