I didn’t have any context, so I went shopping and it looks like you’re right https://www.gmperformancemotor.com/category/ENG.html

Which is a bit wild to me because I looked into adding a supercharger to my 2010 Camaro last month and it was 7-9k DIY.

I’ll be honest 200hp doesn’t exactly blow up my skirt

I get this is a pretty nice product that they won't sell in huge volume, but that is really steep, was expecting something <20k

yesterday post here about Tesla-fied Mustang - $40K of parts https://electrek.co/2026/05/02/tesla-1966-mustang-ev-convers...

Buying motors and batteries from Aliexpress you can probably get under $15K-$10K even ( and that is probably BOM of Chinese car manufacturers for such the engine and batteries), yet having it as a US factory package $27K doesn't look that bad for me.
