Shawn, what is considered a low price? Is the BMW a direct fit? Which model unit are they using? If I could get a direct fit upgrade under $300 I would be happy. I wish I still had the specs on my HR unit. I can't find them on the net anymore. It might not be much more than stock. It is over in OK so I can't measure it. I am pretty sure that one was $200-300 back in 2000 so not cheap. It did come with a yellow HR sticker on the TB plate, so had to be worth it! Ha!

I run a 75mm TB on a 2.3L turbo charged engine with a 63mm FMIC compressor side and 75mm intake side, ported intake to match head and it all works fantastic on the street.

Got the Mustang 65 mm TB mounted today. Everything fits with the 951 pulley screwed to the TB. Just clears the turbo water pump with no modification. I plan to to test drive it tomorrow.

Hey Shawn. Did I miss something? there is a vac port behind the throttle body in your pic.

Some of the early TBs were slightly different to the later ones as featuring a "solid" throttle cam as shown here, with a shiny rough aluminium finish and a gold (zinc-plated) throttle blade.

From my extensive eBay research, it looks like those throttle cams may have been used on the 944S throttle body, which otherwise looks the same as a 951...
