"family car" = Don't be a moron and buy an ITB Manifold.

Ahuh.

They're really only a benefit for high revving engines and you'll lose a bunch of low down torque as you won't have any runner length, which means street drivability will go waaay down. They're also leaning to more of a supporting mod to remove manifold restrictions rather than a power maker.

With the cross section of all 3 head intake types a 51mm butterfly is about perfect.
Access to machine shop and maybe 50hrs, 8 hyundai getz throttle bodies, tig welding also.
