Hey Guys,

I have been looking at upgrading/poting my throttlebody and wanted to get some feedback on whether it is worth it or not based on my current set up. I am thinking of taking my ITR tb and getting it ported out to 68 or so.

thoughts?

Bigger is not always better. Yeah the more air and fuel you cram in the more hp. In terms of your particular engin performance, its sometimes better to run a smaller t-body to get more consistent power then have a big bore t-body and have the car fall on its face when you go to take off. If you were planning on big hp or upgrading the flow of the heads and exhaust i would say then go get a 68mm one.

 

I felt no difference with a 70mm TB up from a stock h22.
