I heard that the automatic TB is 2mm bigger than the standard? Is this true? and if it is will it fit on the standard?

 

it will fit just fine, just swap all the sensors from the MTX to the ATX before you put it on.

 

almost. the mtx tb is 49mm, the atx tb is 52mm.. which is a 3mm increase.

 

Has anybody in here done the swap?

 

ya i did the swap and i have a iceman intake too, all u need is socket set man real easy if ur a car guy all i would do is go to a general parts store and get the TB gasket incase urs is ripped or something to be safe take out the battery if u need more room. it was a noticeable gain

 

what kind of noticable gain? faster response?a little more pep? what do you mean and what did it do to the gas mileage, right now ime getting around 38-44 mpg,
