Throttle Body Question

[GalantGreg]

I ave a few questions about these throttle bodies. Which one of these throttle bodies is the best for my new motor? The first, second, or third one? Also, are there any places that do porting of the throttle body I can send them to?

1st one is the small 2G, 2nd is the 1G turbo and last 1g NT. You can run the 1G NT if you make the intake piping work. As for porting- Throttlebodys.com.

Is the 1g NT a better throttlebody?

Only in the way that you remove the elbow

Throttlebodys.com does awsome work, I have a 1g that ported to 63mm, and its awsome quality. I would recommend them.

I am planning on contacting them tomorrow. I'll most likely do the NT throttle body.

The NT TB wasn't designed for turbo models. However have Throttlebodys.com do a rebuild on it and they will put in the necessary upgraded parts so it will last on your GST. The NT can not be ported.

Also know that you don't necessarily need to port the TB, the stock TB has gone plenty fast. However, you should definitely freshen it up by replacing the shaft seals. Those will almost always cause a boost leak as they wear and can be a PITA to replace, but are well worth it.

2g guys benifit more from a different throttlebody than anyone. I gained almost 10mm, which seems to be alot to me, couple that with EVOIII intake manifold, should make a noticeable difference.

My shaft seals leaked horribly. I went from 17inHg to 20inHg at idle when I replaced them.

I went ahead and used the NT throttlebody. I had Steve rebuild it for me.
