All 150 and 180 Bhp models can be mapped to 200+. The limiting factor is KO3/KO3s turbocharger. We have run a few to 300 bhp with forged pistons, anything above needs rods. The cranks are very strong. The KO4 will fit into a Golf and TT, but not on the Ibiza as the engine mount is in the wrong place.
