the turbo was the one i wanted. i knew i needed a big 1.15+ ar housing and i want to see how much power we can make on this setup. it was between a borg s475 or s480. both you can get real cheap with a 1.32 t6. i got the s480 for 825 shipped so the price was right. you need the small turbo to be able to breath threw the big one and with a 1.32 it can easily.
i have looked into cooling between turbos but feel i will be able to achieve what i want with out it. intake temps have not been any different so far. i should have the new motor done in about a month so we will find out more when we can go over 30 psi.
