Another recent addition was a BBK 75mm "Power Plus" throttle body


Upon opening the box finding a brand new TPS sensor was a nice surprise from the other BBK T/Bs I've ordered in the past. Wonder when this started?

The factory TPS is a bear to remove from the stock t/b, so I just left it installed.



Also included is new hardware and a gasket. I won't be using the BBK hardware (unpolished stainless socket head cap screws) and will instead use the existing hardware I have for a factory appearance.

Note, the *real* factory T/B bolts WILL NOT work with the BBK t/b, the washer is too large to clear the larger bore. The hardware I picked up is narrower and just clears

Some reference pictures -

The black coating is used to improve the seal between the throttle body bore and blade, this improves idle quality.

I gave the exterior of the T/B including linkage a couple coats of Eastwood clear for bare metal so it wouldn't get oxidized and discolored by next year

Installed.

Because of my unique configuration, the throttle body is mounted upside down so you don't get to see the 'pretty' side of the T/B

Honestly, I prefer it like this anyway - now it looks like it's still a factory part installed!

I did not use the BBK-included hardware since I prefer the factory looking gold-tone hardware I had installed previously


The engine bay is ready for a cleaning. You may also notice the new, revised IAC hose setup I installed. Little cleaner look, made it using another IAC 90 elbow and the straight plastic section and barb from a 98-04 CV/GMQ IAC hose, secured with stainless crimp clamps
