Q45 Afm On A Rb20

[Bsa]

So I went to get a z32 afm the other day from my local jap wrecker they had none but they had a q45 one I was wondering if it would work the car is getting tuned soon so tuning sorted just want to know if they work

Q45 AFM is bigger in physical size...hence it will not bolt straight up to your standard airbox (assuming you are still running it) without modification. If you're running a pod, you will require a different AFM adaptor than the item which is suited to a Z32/standard AFM.

Q45 AFM will work fine. All the heresay that people post about regarding idling/tuning issues is misguided. I personally am running one on my RB30DET and had no issues with idle or tuning whatsoever. I know of several other examples on RB25/RB30's with similar setups and no issues.

If it were me, and I wasn't going after spastic power (350+ RWKW from a single AFM setup) then I would go a Z32. Simple boltup and retune to get it to work.

Im going to be running a 4 inch intake anyway and I can fab up a adapter at work so that's no problem cheers for your reply mate they are also cheaper to buy

z32 maxxes out at slightly more power than a q45 anyway

if you can get a z32 it'll be better but if you run out of time the q45 should be fine, will just be a little harder to bolt up as said.

Yeh some people said this to me but then others said Q45 AFM maxes out at higher power levels

I didn't know which way to go, but a Q45 came up at a price I couldn't say no to. Guess that's the main thing that it comes down to. Price.

at 5.12v (maxxed) the z32 afm is flowing 13% more air than a q45 afm
