Nick Williams 105 mm Throttle Body
Nick Williams 105mm throttle body. PRICE REDUCED $575 shipped. I bought this from Drew (ZBADESTZ) last year when he de-modded his ZR1. It sat in the box until recently when I installed it on my car. I pulled it off because my car was at a shop getting fuel system upgrades and a retune to match. The throttle would hang open slightly. Not dangerously, but annoying. My car also became a little harder to cold start with it on. I reported that to Drew and he said he had a small initial issue with it hanging up but was able to tune it out. My car was at this shop and we did not have extra time to tune out those issues, so I pulled it off and am just trying to get exactly what I paid for it. Drew ran it on his ZR1 for 5K miles and two 1/2 mile shoot-outs and it worked great for him. Includes the jumper harness for complete plug and play. Just trying to get exactly what I paid Drew.

I have used both the NW 105 and a 107 on a few of my cars. The definitely not the best for boost as they do hang the blade open. As the OP said, they can be tuned out with quite a bit of work. They are AWESOME for NA and N20 though. They don't hang open at all. In my opinion it is a phenomenal mod for a big cubic inch N20 motor.

It bolted up just fine to my snout and sealed, but I noticed that my snout could have benefited from a little bit more porting to match the circumference perfectly of the TB when looking through the open throttle blade.
My Lingenfelter snout is custom ported and polished to 106 mm but that porting work may not have been centered perfectly. There is no restriction with my 102 mm, but it is not perfectly aligned with the 105 TB. But again, that is probably my individual snout. If I were to remove +/- 1 mm of material on the side that was slightly shrouded, then the small restriction would be removed.
