Do a search mate lots of threads arguing over if they are good or bad! lol

My 2 pence worth...........
Great for torque and will take more BHP than a CVH bottom end, but needs at least a Stage 3 big valve head, high lift cam, and big turbo to make any power after 5500rpm.
Also IMO only.... it's too expensive to get the most out of it so may as well have gone zetec turbo, and doing this MFI is a waste of time.
