For a well modded SE and SVT, the optimized TB would suit you best. Only if you have a way to dyno tune your car should you run the 65mm one as it's been dyno proven to lose HP without those fuel changes to compensate.
I sell optimized SE, SVT, and Zetec TB's (though I'd rather wait until the dyno results come in for the Zetec ones first
). Email me for current pricing info.
