Hi, I saw your website the other day, and would like more info on your '250HP n/a Impreza.' What is the "Modified Runner to Throttle Body" mod? I can't tell from the pictures. Also, does that car have stock headers, or aftermarket? If aftermarket, which ones?
their reply:
Hi, thanks for writing us. The runner mod is an OEM Runner from a '96 legacy. It provides the runner with all the hoses for oil to go back into the engine rather than an oil can. The '96 legacy ran the same MAF sensor without the second air box, so it was easy to adapt it to the '99. The car has borla headers, hi-flow cat, and cat back system from GReddy EVO. There is also a lightened flywheel. We are working on a hi-compression short block which will bring the hp to over 300hp without a turbo.
I think their butt-dyno's are a little off...
