2000 Boxster Throttle Body

[redpepperracing]

Any larger TB will require a larger mount tube, and a larger intake tube, which leads to 'why not increase the whole intake box', and then 'well, why not the exhaust headers', and then 'why not the muffler'....it's a slippery slope, and after doing all of that, you are basically wasting your time if you don't get it tuned properly. Simply bolting on a larger TB isn't going to do anything for you by itself.
