throttle body and plenum, or shorty headers. i would get long tubes, but it's just two damn expensive. which would i see more of a gain from?

I have seen dynos of SUPERCHARGED 4.6Ls only gaining 5-8 RWHP with shortie headers, compared to my gains of 15-20 RWHP on a N/A engine.
Shorties suck!!

T/B and plenum.I went with the 75mm from Accufab.Don't waste money on shorties,wait untill you can afford long tubes.They don't cost any more to install and if you do it yourself it will still be a major PITA.The hard part starts when you remove the old manifolds and ends when you get the new headers in without leaks.

Save the cash for LTs. Better yet, since you already have a X and will have to replace it if you get LTs, get some gears. By far the best bang for your buck with your current setup. Get gears and either a programmer, custom tune, or one of the 100 dollar black boxes to fix the speedo.
Car will be far faster than any of the other mods (LTs, shorties, or the intake stuff).

I hate to say it, but I highly doubt you will be able to feel the "seat of the pants" differnce in the T/B and plenum either. Gains of 8-10 RWHP are pretty typical, and that is on a car with headers/exaust already installed.

I agree. The cost/power gain ratio here is horrible and you wont feel a difference with a plenum and/or TB. That should be one of the very last things you do.

RE: more mod advice
thanks for the info. i figured shorties were a waste, but i had to ask. my only concern with getting gears is highway driving, and the cost of installation. im not even going to attempt that since my tools consist of two screw drivers and a hammer. if i get gears do i need to replace the bearings. my car has 44,000 miles. also is there anything else i need to be aware of when getting gears?
