ive built four of these manifolds now, three modified stock manifolds and one from scrach, we have figures back from one with stock manifold moded, and we gaind 2hp and about 22nm of torque. the car dynod at 242bhp and 220nm torque, on stock engine running stock fuel. its not rocket science but you do have to be carefull or you will lose power.

The problem is the output from the steering rack and the main steering column itself for us RHD boys. I believe ROCO performance over in Ireland have modded 2 stock s2000 manifolds to fit - but I dont know if anyone has power figures for them yet - but suspect a loss.



The runner lengths are from a known proven system used on F20 motors and also F20 heads run on K20 motors in british touring cars

thanks for the plug ian have to say that manifold off john is pure art. hope you didnt use it, its way too shiny.
