Is this for a weekend toy or a daily driver?
The E89 30i is (IMHO) the sweet spot for the E89. It would feel noticeably quicker than your current 2.5 E85, and still be reliable in terms of the engine. As a daily either this, or a remapped N20 (with the cam chain/follower sorted), would be a good choice and the B12 suspension kit makes a big difference to how the car feels on the road.
For me, if it’s a weekend toy car, E85 all the way. A 3.0Si is going to feel a world apart from your 2.5 in performance terms. Again, a suspension refresh but with standard O.E. Shocks will make a massive difference to how the car feels.
