You already know my thoughts on this. Its been my dream build forever and i think we should do it. I go sr20 and you go rb25. The more i research it like the sites i told you about the more reasonable it seems. SR swaps are cheapest due to using the factory motor mounts but an RB20 or 25 are only a little more. All are reasonable but the RB26. The steering on an lhd usdm car has to run right where one of the turbos sit. Plus the RB26 uses an awd trans so youd have to get a RB25 trans. I say RB25 or SR20.
