Should a 65mm TB fit on a 98 sixer? looking around for throttle bodies, i find that 56mm seems to be the only choice for V6's, so im just wondering. also, should i get the 65mm?

 

You wont see any gains from a throttle body. It should be one of the last things you upgrade on your engine.

 

i have never looked into this, but as long as the throttle body holes are as big as the intake holes, that is the maximum size that u can go to actually accomplish any thing, and bigger and ur just wasting money.

Like i said that is about all i know, u need to find out how big ur intake is and find the throttle body to match.

 

so i shouldnt even think about getting a throttle body just yet?

 

No you shouldn't, or your car will get mad at you.

 

haha ok. thanks guys.

 

yeah...i wouldn't mess with it...I got a 65mm for my '01, and the acceleration is weird...i have to manually downshift to get the engine to kick into acceleration...i live with it, but yeah..lol, wouldn't have bought it if i could go back

 

that sounds like a TPS problem


and to the OP, no dont waste your money on a throttle body

 

you can go for the bigger one but like they said, dont.
