as far as the intake plenum goes , it sounds like i will definetely be wanting a aftermarket one as even the 2000 model plenum is very restrictive , i dont understand what all this fuss is about the duratec se is either , or the diffrence between the zetec and the zetec-se. i wouldnt really want ot spend 600 bucks on a engine that only makes about 10hp more and about 15-25lbft of tourque more , not worth it with that kinda money you can get a good turbo or something. wich brings me to my next conclusion , for some reason my heart doesnt trust aerocharger quality wise, ive been hearing alot of good stuff about tom's kit but it seems more like its setup for guys that just want to run on the drag strips , and i want something that will make more car more fun to drive with more upgradability in the future , kinda like the revhard kits for the honda's, man if i could get 195whp for that much money i would be satisfied , but i would not like to run a turbo without a intercooler , and proper oil cooling for the turbo , and a b.o.v. the intercooler isnt the real problem , its just that alot of these kits like the aerocharger ones dont even have a oil feed or return line for the turbo i think ( dont know about hte fmax or other kits) seems like you just pour in a bottle of their oil (wherever specified by aerocharger that is) and it doesnt seem likely to be very wise. if i went the turbo route iw ould want a kit with a dinky t3 that would spool fast remain reliable , and easy to maintain.
