I am looking at upgrading my 05' VIII MR to a IX turbo for autox this year since I can't afford 2K for a Bushar 20G-LT right now. I think I already have the bigger hotside so is there anything else I should upgrade to make this a IX motor?

I have done all the Bushchar upgrades up to stage 4.

 

use the search before you get sets on FIYA

 

You need the install kit.
