Having it set up by a professional will give you better value for money than any other part/mod

With mfi I would only trust the following company's from mine and friends experience
Oddkidd creations
Jamsport
Norris Motorsport. Nms
Motorsport developments. Msd

I wouldn't bother listening to half the stuff on here to be honest, every mfi car is different due to it being such a old system, some hit the limit way before 200bhp and I've had one running 231bhp at 23psi boost with

Turbo systems unlimited boost chip
Stage 3 hybrid/ Collins actuator
Piper 285t2 cam
Burton double valve springs
Bailey breather
Radtec front mount
Modded metering unit (nms are good for this)

Otherwise all standard with ap 4 paddle set up

If you want a cam just fit a decent cam and choose your own valve springs as the ones in the off the shelf kits are all crap

So if you want a cam I would fit
Newman phase 4 cam
Newman solid lifters
Newman double valve springs

And do it once, don't for get you will need the following, breather system upgrade, clutch upgrade, new ignition components and full service after running cam in

It's not just a matter of wacking a cam in and going for 200+bhp


I would save my money and just get it set upto it's best as at 180/190bhp you won't need a clutch or breather upgrade and won't need all the stuff to change cam

But saying that, a "genuine" 200bhp rs is great fun to drive
