T/b, Maf, Cai - Wtf ?!#

typically if you are going with a 70mm TB then you would want between a 70 and 76mm maf. 76 is a bit overkill unless you plan on making futher serious mods in the future, but for the price diff. in a 73 and a 76 it doesn't matter much what you get. You could probably still get away with a 65mm TB, but a 70 is a great middle of the road choice. Don't go over 70 unles you are running boost. I've heard some people on here that aren't too happy with the systemax setup. I have the trick flow setup and it's awesome. I'd do a little more research on which HCI package you want to go with. Whatever maf you go with make sure you get the correct sampling tube for your injector size. I'm guessing you still have stock 19# injctors so you would want a 19# sampling tube.

the MAF is usually bigger than the TB, NEVER smaller, be sure to have your MAF calibrated for the correct injectors (24#'s most likely)

I run a 70mm throttle body and a 73mm mass air meter calibrated for 24 lb. injectors. Works nice.
