nice project...but only 8psi? thats no fun lol.
I ran my old 2.0T at 13-14lbs daily on a bone stock 170k mile obd2 aba for a VERY long time before the h/g finally went. then i pulled out the tired half blown t3 s60 and slapped in a $100 ebay t3/t4 along with some arp studs and a c2 spacer. then raised the boost to 21psi. tons of fun until i got rid of the car.
it put down 203.7whp on the small turbo at 14psi. im guessing from the butt dyno that it was at least 275whp on the t3/t4...at least thats what it felt like lol
crank that boost up and have some real fun with it man. these motors can handle plenty of abuse
