Slant six turbo cost analysis: 300 hp

The stock super six manifold people treat a little more like gold than it is. You LIKELY won't find one for under $150.00 unless you found it in a junkyard yourself.

Also blowthrough mods shouldn't cost $500 if being done by yourself.
Nitrophyl float would be about $20.00 and making a power valve is free if you have a bench grinder and some JB weld. Hacking the choke tower off is free or can be done with a $7.00 hacksaw, and then after that it's just drilling a rejetting.

Well, what you say is very true, as far as it goes, but I, for one, am not qualified to do the sort of intricate detail-work necessary to effect the Hangar-18 mods; particularly, not the power valve changes for the boost-referencing, so I elected to outsource it, and hope that $500.00 is not too low... probably is... I thing guys like yourself, who can do the work to bring these Hangar-18 mods to fruition, are in the minority, and most folks would rather pay the freight, and be assured that the carb is going to work... because, if it doesn't, it can produce a multitude of expensive problems, and can do it unnoticed, and very quickly.:oops:

Thanks for the suggestions and info. I'll get around to incorporating this into the main info page, soon (I hope!):coffee2:
