I have a friend that makes billet engine parts for trucks and SUV's like the F250 and Hemi. If I had him make me a custom billet 350Z throttle body, what size bore should I ask him to make it?

Mod wise, I'm just going for bolt-ons at the most extreme, maybe a mild cam. No super/turbo, nitrous etc in my future.

This is a video of his type of Brother cnc machines cutting a piece of steel:

wow that machine is very tempting to own. So cool!!!!
as for the throttle body size, i have no clue man!! I am guessing like no more then 5mm-10mm wider than stock for sure! but than there is no point of wider throttle body if your manifold's opening is still stock size. Good luck man

 

keep it stock ...

 

^^ +1

 

+1 on stock.

 

Sounds like I should keep the TB stock...

What kind of billet project would you recommend? He has access to that cool machine, I can't let that hookup go to waste

 

brake adaptor brackets. get the evo/sti f50 brembo calipers to work on our cars. dont wanna let this free R&D go to waste lol

 

If you are serious and the adaptor brackets can actually work, then he will do it. He has one of these too to make the measurements,they cost about $50k to $80k depending on options:

+1 on brake brackets @ an economical price

Maybe economical shift *****?
-alot of ***** are stupid high priced

 

Stupid work, I'll to watch it when I get home. +1 on the brake brackets

 

Brake caliper brackets for the 370z setup.

You'd probly need quite a bit more work to your engine before your TB becomes a limiting factor.
