Hahahahaha, another CSVT owner that's hooked
How much power would you like to get out of your car? Is it mainly a daily driver that you rip through the streets/highway with?
The easiest and most bang for your buck setup would be to find a low mile '01 or newer 3L with the typical mods and upgrade to clevite77 rod and main bearings and swap in your SVT cams w/ their timing assemblies.
You can keep the 3L oval port UIM and LIM, but you would need to make a custom fuel rail.
-OR-
You can port match the 3L heads to your SVT UIM and LIM ( Along with porting and polishing them....)to make "tumble port" heads. This is the more envolved option, but you will get a lot more power by doing this. I went this route with my car(amoung other things)..... and turbocharged it for good messure
As far as your trans goes, you can either have HMS rebuild yours with every upgrade available and an LSD ($1500 +/-)
-OR-
You can go through Exdelayed or
www.car-parts.com for a used Duratec MTX75. I'd look for a non-SVT trans as they are most likely less beat, and look for a 2000 or newer as they have the most currant upgrades. One can be had in the $400 range. Add a Torsen LSD for about $500, and you're good to go.
Hope that helps,
