I may be wrong, but the OP seems to be inquiring about boost setups that require the least modifications. Hence my comment about the STS needing the LEAST hardware mods. Now you of all people should know the FHI thoroughly shafted all N/A owners by not using a common lower engine cross member, giving us a 200ft/lb pp and 196hp clutch disc, and no hood scoop to provide room for a TMIC.
To acquire these parts would be costly and time consuming.
