I know the mivec will allow the motor to breathe more air than due to variable valve action over a non mivec 4g63, but with aggressive cams wouldn't a mivec 4g63 flow more air with aftermarket cams over stock?
Or are the stock cams on a mivec 4g63 that good? If so, why would a company like Cosworth make Mivec cams if there are not significant increases in power?
The way I see it, the stock head is designed for the stock turbo. You add larger turbo that pushes more volume on a stock head which retains the same volume, then you will not realize the full performance potential of the new turbo. Of course this implication would apply to all parts associated to the movement of air from the intake to the exhaust.
I can see this agrument applying more to those who only do a cam upgrade.

from what ive read alot of bbk users have gone with 750-780 cc minimum. it wont hurt to go bigger, since most tuners can make 1000cc or larger very drivable, it just depends on what ur plans are for the future...on the topic of ur cams, another thing to think about is the # times u will have to tune ur car. im not sure if u do dyno tunes, mail in or email, but if you're paying to get the car tuned, thats an extra session u will have to pay for in the future (one for turbo setup and another once u get cams). If it were me I would do all power upgrades on my agenda and get it tuned all at once, and save $ i would have spent on an additional tune. spending money on tuning is absolutely necessary, but i try to optimize what i get from each tune..

Agreed.
I think once I get this turbo on and a few other smaller mods (O2, FMIC and LICP) that's pretty much it for me. I would like to have the install and dyno tuning all done in the same day.
PS - At what power level do I need to replace the stock clutch?

As has been mentioned several times, I would do the turbo first and then the cams. The turbo will net bigger gains initially, and the upgraded cams will be able to build on the newfound power.

so the S1's, are they a mild cam?
Also how are these cams? Are they also good if i am gonna do a FP red or the CBRD turbo's?
Cosworth M2 Cams w/valve Springs
There is a guy in Canada selling these so im deciding. Not sure if i wanna do cams cause no one here in my city i trust to install them... you americans are sooo lucky to have experienced ppl who know this car... I WISH!
