what throttle body should I go with?

[pyschoslipknot]

I'm looking at getting the jm fab smim and my question is what throttle body should I use?
The throttle body flanges for it are the accufab 75mm tb, bbk 75mm tb, nissan q45 80/90mm tb, and the power plus 75mm tb.
Also where can I get them.
Thanks
Bryce

1G throttle body are 60mm, wich is the same that 2.5''. If you are using 2.5'' intercooler piping, it's not necessary to go with a bigger throttle body cause this part wont cause any restriction. And the street version of JM intake manifold are made to accept 1g TB as well.

Oh yea I forgot to include that part.

1g Throttle body will be more than enough for most people.

1G TB. Better yet NT TB. You can call Steve from throttlebodys.com, he rebuilds these. Makes the bore 63mm, instead of 60mm and puys a half shaft mod, which he says equals 65mm @ WOT. I' ve seen Turbotrix built EVO with GT42R and everything else run 9.2 with stock 60mm TB.

I run an accufab 75mm, I would stay with a factory unless you are going max power drag build or something like that. I have nothing to back this up, this is just my opinion.

Don't get a throttle body with with the half shaft mod. It makes the shaft weak and can break. Yes I have experience with that as mine broke off the starting line at the Drag strip last weekend.

Get a 1g non turbo throttle body. They are nice because you can clamp your upper ic pipe to them. They are also 2.75" inlet.

If you decide to use a 1g non-turbo throttle body, it has to be machined to accept the turbo shaft seals.

I said use Steve from throttle bodys.com. I have NT TB with turbo seals and everything else, incl. half shaft mod, never had any problems.
