Thanks for the map. Now I just need to read up on turbo tech a bit so I can understand it
I am just running stocko R32 GT-R turbos at the moment. I have to pull them off shortly to fix a head-to-turbo-manifold leak so I am installing some goodies at the same time. That got me thinking... and I figured given the propensity of the stocko turbos to let go, and the few horror stories of reversion, its probably reasonably cheap insurance to change them let alone the other advantages of steel wheeled bb turbos and 15 odd years of development.
However the rest of my car is very stock and I don't have the money to upgrade all the support systems at the moment. I want to try and find a turbo that gives good performance -- average power is what I care about -- on a stock car but also has some headroom for future modifications (cams, cam gears, injectors, etc). The GT-SS seems about right but the HKS price is too rich for me.
