Some Performance Questions

[LegendofC]

Hey, i've got a 95 eclipse gs, i am looking at the tuning guide for performance modifications, and i was just wondering what some of the things mean, and where i can get some of the things done...and what to ask for.

Questions:
Bored-out Throttle Body

Which is the best size to get it bored to, and where could i get it done?

Cylinder Head Porting
What exactly does this mean? How do you do it/where to get it done and what to ask for.

And my last 2 questions are about the Air/Fuel controller, and the Ignition timing controller...where can i get these, and about how much will they cost?

Any answers to these questions will be greatly appreciated.

as far as the TB goes, your best bet is going to 55mm, anything larger is recommended if you're going to turbo it, some people also like to just purchase a Jeep TB instead of porting which is 60mm I believe. You gotta ask around wherever you live for a porting service, I'm sure there's probably several places that'll do it.

okay thanks, i may go to 60, because i do intend on turboing it in a few years.

But if anyone can answer my other questions. It would be appreciated.
