Long story short I bought a used s trim vortech that I sent out to get upgraded to a si trim and vortech told me I need a major rebuilt which would come to $1000. They offered me a new V2 si for $1200. I'm definitely going to jump on the new unit. My question is I can get the V3 si for a 100 bucks more which I like because of it self contained oil system. I'm planning to run 13-14 pounds of boost maybe more in the future and they said the V2 would be better for my application cause of colder oil circulating through it and the V3 will get hot with high boost. Anybody agree or disagree with this. PLEASE HELP ME decide which one to get. THANKS SVTP
