Been gettin' emails and phone calls at the shop askin' about this pic so for those that haven't seen it...


So far, I've milled the original inlet off and installed a "wall" to define the new inlet shape. Lower bolt bosses were removed because I just couldn't see workin' around 'em like normally seen in other port jobs. I mean, if we're gonna do this why be limited by a coupla bolts? The bosses will of course be relocated. Their location will be defined when the new outlet is completed on the new inlet plenum.
Yep, hours & hours (literally) were devoted to checking/confirming/guessing the tweaks needed to make sure rotor timing between inlet vs outlet would work.
