I'll start off with mods:
RB20DET
R33 S1 Turbo (R32 actuator)
JJR FMIC
GFB Stealth FX BOV
POD
When I was running my standard R32 turbo, FMIC and POD, on my boost gauge it would read 10psi with standard BOV. Once I fitted the GFB one, boost rose to 12psi all the way to redline.
Now that I have fitted the R33 turbo with R32 acuator (no boost controller whatsoever) boost under full load at about 5-6000rpm hits a peak of 15psi.
I've tee'd the acuator hose into the hose that comes off the crossover pipe to the bov. It's about 30cm long and I've got a feeling this might be a cause rather then the standard r32 acuator as it wasn't a problem before??
Cheers.
