Bigger Throttle Body & Intake-Manifold

[mengz]

any difference if i change my stock throttle body & intake-manifold to a larger/bigger one? say maybe a 4g92 mivec throttle body and intake-manifold, which its size is larger than my stock.

any of u guys changed to a larger throttle body & intake-manifold for ur car? wat are the results?

cheers!

upsizing your throttle bore alone will actually do you harm. You might run lean. Of course, it's different if you make some changes to your fuelling as well.

ahhhh...this one no problem, can go for dyno tuning and adjust the fueling with the safc2. now, im still thinking of whether to get a bigger throttle body and port match the plenum opening to the throttle body size. or get a bigger throttle body and a bigger intake manifold.
