Hey guys,
Im doing this upgrade (St185 twin entry system and ct-26) to my St165.
Reason for doing this, needed a new turbo, got a 185 turbo and exhaust housing, then got down pipe and manifold, rather then runing a gutted cat. Thought more long term for if i wanna go to a ct-27
Just curious as to if I was to only replace the manifold, turbo, downpipe ect, using adequate spacers etc to make it fit properly, would i need to upgrade the intercooler or not, just wanting to know if upgrading to the 205ic is neccesary, or could i just upgrade the exhaust, and still run the stock st165 Ic with no problems.
Basically wanting to know the benefits of running the 205 ic, and if I need to or not.
Thanks
Vinnie
