It depends on how well developed your up grades are. There is always potential, and vehicles really don't persay go obsolete. It's not about revolution boys and girls, it's about evolution. One of the things is understanding that most modern cars have very extensive sophisticated management systems, mind you of course with in there own required operating spec.

Beyond that you guys need to understand that the available tuning software and firms capable of providing tuning services for Subaru's and Evolutions is simply vaster and there is a lot more developement and market base.

So in short their intial potential for expanding the pre existing factory architecture is cheaper and more up to date. The 370Z is very sophisticated and in terms of driver to vehicle interface is more friendly combined with well developed suspension and stopping power.

The biggest thing you guys are going to face is really the complete replacement of a system and or how far you can expand the existing architecture. And or how deticated you are going to be in such a project.

The one thing that nothing can change is technical driving skill, and against cars with driving aids out the kazoo the ( testicular ego of man has drastically increased from that of past decades where men ended up in a wall, tree, or up in the tree's if you went out like a champ. )

You need to early on decide, am I going with a road car or circuit car. You need to decide also what kind of enviorments you will encounter, most the very fast and powerful machines have years of developement. Also understand that there is also going to be those that will run their engines or set ups at the brink of distruction. The tuning potential of the 944 is not to be over-looked.

Cheers-

In short, you 944 boys and girls have some work cut out. Start with a complete overhualing of the fuel system to meet the ( target operating spectrum ) and go with proper engine-management.

Next Emphasize on the induction system and don't just replace one or two parts, I mean a complete system designed to operate with selected turbo, you need to achieve maximum boost and keep it consistant thru your operation zone but also under various throttle conditions with excellent recovery. This however should be balenced with the mechanical end of the engine and well we're getting into more then I have time to write. Last but not least, most over looked is the transmission, ratios, clutch and fly wheel, shaft, and rear end specificly set to your requirements. Don't for get to leave a little room for drafting about the last 500-800rpm's.

Cheers, good luck!
