93 cobra TB question

[habiv]

I have a 93 cobra and I am going to get a new throttle body. The car comes with a 65mm stock. Would 70mm be too big? The car has no modifications other than exhaust and headers and I plan on doing nothing to the motor. Thanks

You don't neeed it. Won't do much for you.

I have to buy one anyway because I have a problem with the stock one. Should i still stay with 65mm?

Anyone? Will a 70mm impede performance on the cobra with no motor mods?

I've always been told you go 70mm when you go with serious mods. I would stick with 65mm unless you have big plans then go with 70mm.
