Well there you go, its running 8:1 compression and using NOS as well so it'll need to rely on big boost and NOS to pull 300kw atw out of the 1.5. Still, must be a lot of work to get that much out of the little donk as thats 200kw per litre. Suppose its something different, not my cuppa tea doing it with a 1.5 SOHC, but good luck to him nonetheless.
