Had my NC3 for almost a year now, love it overall and can’t stop thinking about the BBR stage1 turbo conversion.
Having exhausted searches in forums etc, I wish I had the top 3 ‘gotchas’ from those with real-life experience of these conversions.
Maybe underbonnet temps now become excessive, support is substandard (subjectively of course!), a new std clutch lasts very little, insurance companies take the mickey – whatever the issues happen to be.
My first road bike was a Kawasaki 750turbo, so ain’t a turbo virgin. Also have a ZH2, so still into forced induction - but at this age I value reliability and peace of mind above all
Hopefully this will talk me out of spending the car’s current worth on an 11-year old car 
I cant help much but i have just bought a Honda S2000 as i really fancied an NC but just wanted something with a little more sparkle.
This isnt an advert for the Honda but just to say i looked and looked at the tuning packages but just could not justify the cost of the forced induction ones.
The super 200 package looked interesting and not terrible value really for the gains on offer but what i did read about the company in general kind of made the decision for me.
Not sure you will get the answers you want online really as there is what seems a 70/30 split on happy/unhappy customers.
As for the clutch it would be madness not to upgrade it but thats another expense to add on.
I did think that there was a little less to worry about on a Turbo conversion done properly but that may be wishful thinking.
I did read insurance could be an issue, never looked into prices personally.
A rather nice looking red Turbo converted car appeared online about 3 months ago for close to £10k, i was interested but the car i was selling took longer than expected or i may have taken a punt on it.
Had a typeR FN2 and the lack of midrange was hard to swallow.
Not keen on changing the cams, all sorts of issues can arise in the process, let alone the cam profile could easily shorten the drivetrain life. Oh and the bearing mating surfaces will never match with the original cams that wore together from the factory. Oh, you also take from below to add above. I really don’t want to compromise any of the very-low down pull, I find it suits this car very much for leisurely rides.
‘uprated clutches’ can be a can of worms in my experience, I’d love to stick with std if possible.
After-sales support is indeed extremely important, but on a public forum people might be reluctant to be frank (sadly)
I know what you mean about the midrange, I did find the engine a little underwhelming the first time I took it to the redline to be honest but overall Im happy with the car.
Surely somebody on this forum must have had a stage1 BBR turbo NC…
