Throttle body help

[boosted27]

I have searched but still unsure: Upgrading the throttle give any gains? I have heard they do and they don't.

If so what would be the best the Mustang 75mm or the Q45 90mm?

I have a fully built SR (notch)...block built my Mazworx and upgrading to their intake manifold.

depends on what you use the engine for. drag racing/all out power, go for the q45. if a good throttle response is needed, 75mm would be a better choice.

I have one of the ebay throttle bodies on mine which I believe is 75mm, you can put a 90mm on but your intake manifold is only so big, it's like having an 8 inch intake, aint gonna do shit... the 75mm I have is port matched with the throttle body.

See what mazworx has to say with each driving preference. You have their manifold and a motor built by them, I'm sure they will point you in the right direction.
