I just got the ECU for a good price off a mate hehehe! sorry bro not for sale.


HAHA! yeah i want to turbo it, just waiting on a mate upgrade his turbo and sell me his one, wich is the T04b.
The Euro's stock intake manifold, the RBB has long thin runners designed for low end torque as they get rid of turbulence in the runners, but the RBC has short fat runners to cram as much air in the cylinder as possible, but also creates turbulence at lower RPM. This explains the power shifting up after RBC install. So yeah the RBC is much more suited to high RPM and VTEC. The K20 head should increase power everywhere as it just generally flows better. The actual head (without cams etc.) isn't really suited for any RPM more than another (correct me if I'm wrong).

There's a lot more involved in turboing than just having the actual turbo mate, do your research carefully
