What would it take to run the Katech 103TB?
 
it seems like all the C7 guys have had good luck with the 103, whereas problems with the NW102 are still common. For those of us running big boost, would a swap to the 103 be possible? I know less than nothing about the tuning or connectors required, but figured I’d ask. A search got me no where.

a lot of money and hassle for potentially little gain unless you are up over 1200 hp the big heavy blade is not happy with big boost and unless the stepper motor is strong enough (or you ditch it and go cable) I would say you are charting into expensive untested waters. I remember they have NW 100 with the stronger stepper and gears but it's like 600 + for what 5 - 10 hp at 1k ???

look for power elsewhere with FI and avoid the hassle. It's just not that big a restriction. We fiddled around with "big tb" on other turbo platforms like c5 and old turbo buicks and the juice just wasn't worth the squeeze.

It wouldn't work. The throttle control system is completely different.
