75mm or 70mm throttle body

02mustanggt · August 14th, 2009, 12:40 AM

ordering a new throttle body tomorrow.. n/a motor just going for bolt ons right now and im not sure whether to get 70 or 75mm.. would the 75 be an over kill?? or would it make a difference

GTRACER88 · August 14th, 2009, 12:52 AM

75 wont be over kill. It gives you room to grow later.

depends entirely on where you want to go with the car. what are your goals? long term and short term?

does a bigger throttle body effect gas mileage in anyway??

ya. be careful. buying too big a throttle body can cost you low end torque. figure out what you want to do with your car long term. the better thing to buy would be a plenum as the stock plenum on these cars is a bit embarrassing...

Fluffy The Rhino · August 14th, 2009, 01:09 AM

I wouldn't do it unless you were going to do more later. And even still, I'd wait till you had other mods done. Just my opinion.

The loss in torque will not be noticed. Its like installing a cat back and feeling the difference in power... you cant.

If you look at stock plenum and tb, it is actually the tb that has a smaller opening. And you can port out the stock plenum till you get money to buy something to replace it.

You would have gains either one you go with. More with the 70 if you don't plan on doing anything past simple bolt ons. But barely if anything.

02mustanggt · August 14th, 2009, 01:15 AM

go to the HOW TO sticky. theres a post there on all the first mods people should buy. get your bolts ons together. gears, exhaust, suspensions work. Read the post...

02mustanggt · August 14th, 2009, 01:18 AM

that would be nice to get. but i dont have the money for that at the moment..so which should i order first.. im ordering something tomorrow an dont need to spend more than $150

1. Cat-back exhaust, you can't have a mustang without good sound to it
(MAC, Magnaflow, Borla, SLP, Bassani, Flowmaster)
2. Mid-pipe either h-pipe or x-pipe. If you are worried about inspection or emmissions get a catted h-pipe or x-pipe. ( MAC, BBK, Bassani but wouldn't reccommend it since it sounds like a loose convertor sometimes.
3. GEARS, definately a must if you can afford it cause the labor at most shops is 300 to install. 4.10 gears are the norm and there is not a difference between gas milage of 4.10 and 3.73 so get 4.10 if you want the most out of your car.
4. Shifter, cause 3rd gear is a pain in the butt. (pro-5.0 or steeda tri-ax)
5. Upper plenum (Accufab, C&L, Dragon, Trick Flow)
6. Throttle bodie, wouldn't go with a 75mm unless you have heads and cams cause it can actually hurt you. (Accufab, MAC, FRPP, Dragon, Trick Flow)
7. Tuner or chip, with the gears and all the modifications you can squeeze some extra power out with a tune, preferably on a dyno. (SCT, Diablo)
8. Underdrive pulleys, reduces drag on the accesories. (STEEDA, MAC)
9. If you need a clutch (Centerforce dual friction, closest to stock feeling, SPEC)
10. Springs, to lower that 4x4 ride height (Eibach, Steeda)
11. Longtube headers, a good improvement on exhaust flow over the stock but some might have problems with inspections (MAC, BBK, Hooker)
12. CAI, just get a little breath of colder air, only expect between 3-7 hp from these (JLT CAI or RAI highly recommended, Densecharger, Mac, BBK but don't recommend getting a chrome CAI cause it actually gets hotter air, and of course K&N)

Well thats all i can think of right now, with these modifications you will be started on the fast track to having a pretty fast car with a mean sound. And should be running in the 13's to high 12's depending on driving skills.

GTRACER88 · August 14th, 2009, 01:20 AM

Put it in a savings account.

RyanGT · August 14th, 2009, 01:21 AM

I would say get the TB and then port your plenum yourself and buy an aftermarket one later. If thats what your choosing to do.

Fluffy The Rhino · August 14th, 2009, 01:22 AM

Word. Save the money until you can do something that'll really prove itself.

02mustanggt · August 14th, 2009, 01:23 AM
