to make it short im sleeving a b18c1 but i dont know if i should go 84 or 85, i know 85 is max but how reliable is it even when its sleeved? i know reliablity falls on the tuner but as far mechanically reliable is 85 safe? i plan on runing high 20's psi to get around low 500s

 

id keep it low(82mm) for a boosted setup like that youre gonna need the extra meat between the cylinders...

 

I always start off with 84mm...if I hurt the motor, I then go 84.5mm....then 85mm.

I would go 84 That would be a very nice motor. As far as reliabilty i dont see any problem Go for it
