Not sure what this manifold your talking about is? Like the lower portion kind of like the, tork tech adapter plate? Both kb and whipple have their own manifold. Whipple doesn't mess with 2v's im pretty sure.
KB's lower manifold is not something you remove and switch out. And if you got a kb or whipple they would come with it... so wouldn't be cheaper.
well yes the lower intake manifold of a roush 360r/380r... they come with an eaton m90.. but i dont know if like a m112 off a cobra would fit or anything else would fit.. cuz i have searched for a m90 and they are hard find other then ones off a grandprix or thunderbird.. in which the plenum is on the wrong side..
ok talked to roush they said they used the m90 from 2002-2010.. so i should be able to use any roush charger from that time period.. extept the 05+ models have the throttle body on the other dirvers side of the engine bay...
You can't put any other supercharger on a roush manifold than a roush. It is proprietary system and a unique design that is all Roush, you can put an 05 up head unit on your manifold, but only the 05-06 units have the intake on the passenger side. Roush won't tell you that but that's the case, they changed the intake plenum to left side units in 06 and all that's left are the left over units from 05. That head unit by the way isn't a typical m90 eaton unit, it has lobes real close to the tvs gen 5 units made by magnuson now but with difference and are capable of very impressive numbers for its size. Call stage 3, they may have a few head units left but I don't know for sure. Good luck finding one.
