I have the Rev Hard stage 2 kit, and full interior and I run on Nitto drags 7psi so far =13.6 @ 103mph. Only additions to kit are listed below. So w/ full slicks and some weight redux, lower 13's are in reach, that is what I want @ 7psi full interior

Just gotta get my launch down, hoping my new struts will work for me!
Otherwise under 10psi internals pretty safe' if ya want beyond 10psi full internals to be safe!
Turbo's are awesome, and once ya make the investment it's just a matter of turning up boost and building motor to handle it!!!
Good luck!
Mark
