TB questions

[93PGT]

i am still new to mustangs. especially the 4.6. can I buy a larger throttle body, w/ matching air meter and larger injectors? without out going F/I? or is it a waste. I want to know what I can do alomg those lines. if so, what a size thats used commonly? and what all goes to gether as far as corrosponding sizes?

what other kind of parts make a good difference

Unless you're running some boost you don't need a new MAF or injectors; common TB sizes are 70mm or 75mm.

so with a larger throttle body, I wont need to upgrade anything else? I just want to know what kind of things i can do and what it involves.

most people will view throttle bodys and plenums as a complete waste unless your pi or f/i

 

[93PGT]

do you mean full pi, or with just the intake and maybe cam

You can put on a larger TB and be just fine.

You best bang for teh buck will be a PI intake, followed by PI cams, and 4.10 gears. Follow that with exhaust, and then a TB.

as far as bolt ons all i have is a 75mm t body and a cold air off ebay .i dont know if it gave that much more power but it deff is more responsive and snappy

you don't need to change your meter unless your pinging it out as in 300+ HP. Even then you can do a MAFia and make up the extra voltage. I wouldn't waste the money on a TB. Do a upper plenum first and do a PI intake when you can. A bigger TB will give a little 1% throttle response but will only give 1 or 2HP on the graph. The PI swap stuff is a better bang for your buck.
