M112 is pointless unless you're way out there in power, even then, some argue it's still pointless. Way out there being over 350 WHP. Reason being, the gen V m90 housing and a spacer is how it's fitted. So it's far from ideal.
Biggest cost associated with gen V is the blower itself. Last time I looked they were around 300 for a stock one, and a little more with an MPS hub or different throttle body.
If you want use the stock throttle body, you'll keep the costs down. I highly doubt the bigger throttle will help you any if you're near stock. If anything, just reduce the amount of usable pedal movement.
