Looking to go single turbo at the end of this year. Was planning on the 2500, but with the release of the R3 I don't see why not go to it. I am planning on 6 total injectors on a 2 rotor build, E85 capable.

Correct me if I am wrong, but the R3 having the wideband built in would cost similar to the 2500 with the added wideband kit. Why not just get the R3 with the newly added features?

 

Go the R3.

By the time you factor the reduced wiring/hardware/labour involved having the PDM on board, you should be ahead $$ wise even when taking into account the more expensive upfront cost.

 

that’s likely where they’re heading, about half the cost of the R5 too.
.

 

Has anyone used the R3 yet in an FD? I am going to start ordering parts in the next month or two and wondered if anyone had experience yet. Also wanted to see if the R3 fits in the stock ECU passenger kick panel location. Or if thats even ideal with the power/ground wires.
