Converting Rb25 Pfc To Work With Rb20

Hi Guys,

I remember a while back there was a thread made by someone - can't remember who... (Cubes, Roy?) about the problems they were having with their AP Engineering R32 Power FC.

when they looked at it, they found that its basically an RB25 or RB26 unit with a couple of wires changed?

does anyone know where i can find that thread?

Reason i ask is if its just a matter of changing a few wires, then it might be worth getting an RB25 unit, and modifying it, instead of forking out the extra $500ish for the RB20 unit...

I've used search, and had a bit of a read back through the pages of threads, but i can't for the life of me find it! :O

Any help would be appreciated

From the pinout point of view the rb25 ecu is the most straight forward as they are very much alike.

However an rb26 item can also be used but does have an extra fuel pump something or other pinout which I'm not sure what it does exactly.

From memory on the rb25 ecu you swap inj. 4 & 6 pin outs and then snip wire 57.

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      What about if you just give it direct 12v and earth?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
