the only mods on my car are underdrive pulleys and flowmaster cat-backs and a BB&K cold air intake system would i be better off with a 70mm TB or 75mm TB and im ordering the trick flow plenum whenever i decide which size to get

 

You would be better off investing in some 4.10's, LT headers and a better midpipe. Dont waste your time on upper intake till you are done with ALL the other mods you can do.

 

Yeah definately get a midpipe first then gears.

 

actually im getting an x-pipe for my b-day and i wasn't gonna worry about the gears yet the install is too much on a daily driver i have no other transportation and u still didnt answer my question but i agree about the gears i really want some 3.73s the 4.10s imo r way too much gear for the daily driver

 

Well in answer to your question I'd say go with a 70mm TB.

 

thank you but is there any particular reason for that

 

I would go with a 70mm. Until you get some more mods and HP I would go with the 70. I have a Accufab 75mm on mine. By the way Accufab is a good company to go with.

 

There is no disadvantage that I know of by going with a 75mm TB.They will allow you to mod the car without having to get a bigger TB later on.I have the 75 mm Accufab TB and plenum.

 

One thing to remember......MORE AIR====MORE FUEL!

 

well i think i'll go with the 75mm now rather than upgrading in the furture but accufab's TB and Plenum combo is a lil expensive but everyone who has it says its great so i might have to spend a few extra bux this time and besides the difference is only half a centimeter
