Fitting an Audi RS3 engine into a Puma for less than a Duratec? Just an image to offer a clue that you may not know what you're talking about. Oh and by the way, its an in-line 5 cylinder. The block alone cost over £4K. Maybe you could post something of relevance sometime?200hp, you could fart more power than that.,, for that kind of install cost.
Might as well fit an Audi RS3 motor in it, with a tweak there’s a reliable 600hp.
