If that’s a side effect of fitting what’s best available then great…but struggling what’s the easiest option

Would the infamous sw5 be better low down or is that another 997 variant?
In all fairness, if you ask a question like this, you are always going to get a range of answers, on here thankfully, a less wide range of answers than you would have seen on FB or somewhere similar, but still a range.

There have been some excellent suggestions on here, although my original choice was Calver's tweeked 997 cam, the Evo1 & the SW5 are both really decent options too, they are mild-ish cams that pull from next to nothing & will work very well in your engine. TBH, the difference between them is probably close to imperceptible apart from on a dyno. You have been lucky that Oz an engine builder of great renown, has shared his experience on the subject. As he has probably built more engine than the rest of us put together his is probably a really, really good suggestion.

Another alternative is to find someone with a low mileage 1100 & get a standard cam out of that. There must be thousands of unloved & unwanted 1100 / 998 Cooper camshafts about, I am sure I have at least 1. Personally, this is NOT a route I'd go down, but it is an option for a good standard cam that hasn't been mentioned.

Personally, I reckon that there is a danger of overthinking this! They are all decent cams, they will all do what you want them to do & the differences we are talking about are probably very small indeed.
