haha good boy.. the rb20 is good but its just alot smart to go rb25 for more power, the rb20 doesnt have the torque to start spooling bigger turbs! pretty sure the old yellow onevia from jms was running 280rwkw+ with rb20! your most prob better gettin the rempa then save for 25 conversion, it also good because jeff is now remapping 25's yay!!
