I have the HO manifold on my Z24 and I am thinking about upgrading to a bigger throttle body. I have this in mind. Has anyone had any experience with these throttle bodies and what kind of gains I can expect. I'm looking for a bigger gain in mid-high range power without loosing any low end torque. My other mods are listed in my profile. Thanks in advance.

Well,
I have one up in the classifieds at 61mm.
Same tecniques use with the thinner opening, smoothed transition and all o that.
For MUCH cheaper.
Also a port matched HO mani so if you even wanted to do a trade or something.

But as for that particular tb, you shouldn't have any problems with it.

61mm sounds like it would be too big. I'm looking to stay N/A, so 56-58 is probably what I want, but I can't tell what size the opening is on that TB.

At the plate its listed at 58mm so you'll be ok.
