The only RS-T that I have driven is my own, which is a 4 psi setup using a Legacy turbo. Supposedly this turbo runs out a lot on top, and I can definetly feel it, I think. No one has ever been able to find boost maps for this turbo, so we are kind of blind in that aspect. How much more will a larger turbo (i.e. VF22, T3/T4) pull on the top end?Im seriously debating a larger turbo swap, with my eyes on the VF22 right now. Is the VF23 going to be more laggy with a better top end than the VF22? I would like to be able to run some boost through it, with an extended redline as well.
Any opinions much appreciated.
