Hello all, I know my question will be considered a newbie one, I've search, but wasn't able to find a satisfying answer. I've been into RX7 for years, but I only had S4's, I never had an S5. I can have a pretty good deal on an Adaptronic select ecu for the S5 RX7. I'd like to know what I would need to do, to be able to use it on my car?

I know a few differences between the two models, I know I won't need the ecu to control the OMP, for an example, but that's all I can think of that would be a problem.So I'd like your input.

Now I got a stock S4 motor, stock turbo, with a ported wastegate, a full exhaust and an HKS intake running with the stock intercooler and all. I got many parts to upgrade to a bigger turbo, like a fuel pump, injectors and everything else needed. So I really want to know the possible problems.
