Throttle Bodies

[Zx2fst]

I'm making a custom intake manifold, and have been looking at different throttle bodies, to put on the car. I know going to big with a throttle body is not good. but I was just wanting to know how big is to big for our motors, that are running a turbo and fully built?

here is a link to the type of throttle body I was thinking about, just wondering if it would be overkill?

that tb wont work. depending on the boost you are running/ head build/ intake manifold your running, i would think it would be reasonable to stay within the 65-70mm range. of course it would need to be retuned as well.

figure out the area of a "big" one as opposed to this one

That might be cool to try do.

Is that not a twin 65mm?? I'd imagine it'd be hard to feed that thing.....maybe there's one out there that is
like a twin 35mm TB??


BTW....killer price on it..

go with a 4.6l TB off of a mustang , thunderbird or crownvic

well thats what I needed to know, I'd like to dual plates, but if its to big, then I'll just look into a 4.6l TB. I might still get the dual one just to try it and see what happens.

you can get a dual off of a Cobra mustang,

you can get a dual off of a Cobra mustang,

oh ok that sounds good, I was actually looking at one off a cobra. I'll look into that.

ya the bigest TB i have heard of is a 70mm...shouldnt have to go bigger than that...

Shouldnt need to go larger than your piping. Its not going to flow more than your piping so...
