Default curious about throttle body mod'*

I've been looking at doing this mod (see below) but not quite sure that it is worth the money or not. It seem'* to make sense, but not sure if it will really enhance my engine or performance.

Also do you think that a TB Spacer would help this mod also?

A TB spacer in my understanding is nothing more than a TB coolant block off plate. The lack of coolant could keep temps lower.

On the Stage 2.. that'* pretty radical and would probably require the new A/F tables mentioned.

To me.. a slight porting is the best way to go unless you are entering the mid/low 12'* as the documentation suggests.

As far as it'* worth, that is for you to decide. Did you read this thread (right below yours)?

Well I am in no way even close to low 12, 13, or 14'*. I will probably stop mod'ing once I hit the 13'* anyway but we will see, that could change if I really like what is happening. So in your opinion do you think the stage one is better? I purchased a throttle body from Ebay a while back as a core, it'* pretty clean, so would it be better for me to do it myself? Not really sure how to do that though.

Stage 1 is all you'll need. If you don't have a mill and the capability, you're better off buying IMO.

If you take the pics..and information Willwren has supplied..

Head to a machine shop..

They should be able to do this for you for under $50..

50 is a heck of a lot better than 200....

ZZP'* TB (just looked at it, when did they start offering those?) is just another adaptation of what I did 2 years ago. I doubt there would be much difference between their trapezoid shaft and my double flat. If they had countersunk and used flat head screws like I did on Don'*, Boosty'*, and the other 3 of mine, they could have reduced turbulence even further.

Looking at the stage 2
Buy yourself some rockers instead, much more bang for the buck with the mods you have.
