I put a depsoit down on a Sky about two weeks ago and plan to use it as a weekend car that I'll put very few miles on. I plan to keep my current car, a 1999 Saab 9-5 as my daily driver. I noticed that my Saab has a 2.4L eco tec turbo engine, which I assume is probably the same block? I dont have an aero edition so my engine only pushes 170hp but there is aftermarket pcm programing to get it to 230hp safley. My question is could I theoretically switch out the pistons for the sky with lower compression ones from my saab or another saab, use a Saab exhaust manifold with the turbo on there and pay to have some custom programing done and have a 230hp sky? I know there would probably be some more issues such as the sky is rear drive and the saab front so the exhaust manifolds might be very different in shape/size. It would probably as cost effective to wait for the redline but does anyone think this sounds pretty do-able?
