good ideas, will certainly look at having the manifold wrapped, and I thought about a heat jacket for the turbo exhaust housing.

On the cams, does 11mm lift put more wear on the engine? if not, and there are no downsides - 11mm is what I will go for.

As for higher cam duration, i dont mind losing 10 or 15% power under 4000ish rpm, looking for 4-5k faster spool , and a big gain 5k to 9k+. As long as the car idles 'ok' without cutting out, and the car drives smoothly like an NA 2.6 under 4k that suits me perfectly.

any ideas what duration I would need so it doesnt choke untill 9250rpm? 280/272 or 290/280? Am I right to go for stepped cams, or would 280/280 or 272/272 be a better choice?
