Boost is a drug ! you say 350/360 then at a later dater maybe 450 it never ending ffs
Their are some really good engine builders out there you have to decide how mad you wanna go standard rebuilt 3/4k I reckon
Me personally would use mark at M A D I have one of his engines and it's never let me down sound bloke with good advice!
But all tuners will tell you something different talk to them all go with the one you like the best and go with what they recommend
