it was definately a boost spike mid-burnout, i think it hit around 20-22psi while its only been tuned for 12psi. so that would've done it for sure.
if i did a 3L bottom end it'd be a stock 3L.
id rather a forged/strengthened/balanced rb25 bottom end than a stock rb30. being a uni student i could only really afford to do either one and i'd rather the stronger rb25.
