Its a 8 valve push rod head, LOL.
As to the comment that starlet's can make that power, the renault 5 engine is carbed, has 8 less valves and also has a rubbish designed inlet and exhaust manifold. If we were to change the exhaust manifold to a tubular item we would gain an extra 20bhp and then think if we changed the management to electronic fuel injection and have a better inlet mani. We could then up the boost even more and easily be knocking on 280bhp and all this on a standard bottom end apart from some ARP conrod bolts.
BUT, with everything it costs money and there is a budget
Also, it is not easy to get 240bhp out of a starlet or everyone would be doing it. All the guys I know with starlets push around 180bhp with uprated turbo's, fmic, exhaust, induction and remaps. The only way it would be easy to get 240bhp from a starlet, is if you dropped in the 1500cc bottom end and then your talking
Sorry for that essay and thanks for the comments (& debate)
