Question about RA OMP adapter and S5 OMP

need RX7 · 03-07-2010, 12:58 AM

So, I've pretty much decided that I'll be running an S5 engine in my car in the future, and I'd like to run an S5 omp with a Rotary Aviation OMP adapter so I can inject 2-stroke oil instead of dirty sump oil, and also not have to deal with the throttle linkage of the S4 omp. *I plan on having a Haltech Platinum Sport 1000 by then, which does support an electronic OMP.

I've noticed in Rotary Aviation's OMP adapter listing that they don't offer one for an electronic 2nd gen OMP, only mechanical 2nd gen pumps and electronic 3rd gen pumps.
However, I also noticed that Pineapple Racing lists their OMP block-off plate as fitting both 2nd gen and 3rd gen electronic pumps, which means they must have the same bolt pattern.

So, my main question is; Could I use RA's 3rd gen electronic OMP adapter with a series 5 OMP and front cover? Their bolt pattern appears to be the same, but I suppose there could be a difference between the driveshaft(?) locations, or perhaps something else I don't know about?

you may want to give them a call to see if the pump adapter is still offered.
I could have sworn that they discontinued them because of low demand.
But I could be (and most probably am) wrong.
