yeah, ceramic turbo is it’s downfall. for real.
Otherwise, I dunno man…once the turbo issue is resolved it’s pretty bulletproof with none of the RA issues man.
I’m not gonna debate the two. SR’s are proven time and again for being awesome motors…truly…I just really like RB’s for more than HP. Sound, feel and high revs. mmmm…yummy. I should be siitin pretty good once the new NON ceramic unit gets here with my 440’s or 550’s. 
Easy 275 WHP. Enough for me.
(What do i know they, you get PAID to work on that shit all day. lolz)
