Got a question , well a Noob question i about to order the TVS, now my questions is i understand it comes with a 80mm pulley already, now i have a bunch for my eaton m62, ranging from 2.5 to 2.8 pulleys. Can i use those on the Harrop or do i have to order different ones for harrop?

You have to order different pulley from harrop and i think nate is starting to make some if he hasnt already. Harrop offers 3 different size pulleys 80mm 75mm and 70mm and once if you go below 80 you will need a return style fuel system or 79lb injectors and a massive cooling system and a possible build.

stick with the 80mm, under that you will run into heat issues
i run the 75mm, the heat is up there and you should run a meth kit plus more cooling mods
70mm you need a return style fuel system

use harrop pulleys or nate makes them now for thr harrop bolt pattern

Well return style ill get after jan. with my tax return...

Now i have all cooling mods with ported intake mani and dual pass etc.. im looking into a killer chiller saw a post last night for stage 2 for $549
