you win me to it, i have been collecting parts for a few months now, i have a T70 A/R 81, for big turbo, a xs power t3/t4 turbo .63 A/R for small turbo and 2 60MM wastegates, i had 850cc injectors but got the timming to advanced with them so i am putting 680cc this time with my Map Ecu. I am doing a rebuild this month on my engine, hopfully i will start the compound next month too. Good Luck and wish me luck too.
Edit. Is it me not reading the whole thread or you haven`t routed the small turbo wastegate to the big one yet?
