I currenctly have GT-SS on my RB26 with a os giken flywheel. Response is unbelivable. Lag doesn't exist for me.
I'm interesting in going rb30 because I want more torque. However, I don't want to go higher than 550whp because my tranny won't take it, clutch will wears too easily etc.
With that said, I went throught the 6 pages of rb30 dyno and I think I saw like 3 Twin turbo built.
Have you heard of any rb30 with twin -5, GT-SS, HKS 3510 ? what was the income?
Much appreciated!
