Ok first, I live in VA so I need a car that I can have tuned right here in VA. most of the tuners here use AP and not much else. So, I've been thinking of building a hybrid engine with a 207 block with Built (pnp'd with upgraded valves, springs, etc.) 257 heads. If I run 257 heads, I can then use the usdm sti ecu and run a 2.5L cobb AP, right?. In terms of the ECU, will that work? If I get a 207, I want to get the most out of the motor. I don't want to get stuck going with a usdm motor. The thought of a 8k+ redline is irresitable.
