Idk if I ever heard of anyone using rb25 pistons .
A rb24 can be built using a rb26 crank, rb25 rods and toyota 2.4 2azfe? Pistons I believe then it's gona be one hell of a shop charge to make that all work. Just buy a rb25 or 26, rb20 is a nice motor for under 400whp but to build+big power is cheaper to just get the bigger brother of the series.
