I would have to disagree about getting a vr6 to 210bhp being more expensive than getting a 16v to a similar power, i would estimate that to get my old vr to that figure i'd have needed cams-£400, remap-£250 and maybe a second hand shrick manifold-£1000.
Now if i was to spend £3000 it could be running 260-280 after being charged.
To get a valver anywhere past 200bhp it would need to be turbo'd/charged and that would be alot more than the equivillant money spent on a vr.
What I said was:
So true...a 190+ BHP ABF will cost significantly more than a 190+ BHP AAA or ABV....and have less torque.
A point to note:
Getting a VR6 to 210+ BHP from 190+ BHP is very expensive.
Getting a 16v to 210ish BHP from 190+ BHP is less so, assuming you have gone the 'normal' route to 190BHP.
So getting your VR6 to 190ish is cheaper than getting a 16v to the same figure.
But, assuming you already have the cams changed in order to get your 16v to make 190+ BHP (which you will, along with headwork, if you want proper, genuine figures not dyno bullsh!t) then getting the next 20ish from the 16v is cheaper than getting 20ish BHP from a VR6 sitting at 190 BHP.
16v from 190ish BHP to 210 = ITBs and suitable ECU (MS is cheap and will do...Bike TBs can be used...so from £500 to £1500.
VR6 from 190ish BHP to 210 = Cams, headwork, Schrick manifold (doesn't add much power, but lots of torque)? Re-worked TB and a re-map. £2500-£3000.
Assuming you stay NA on them both.
Of course you can Supercharge/turbocharge...but that gets expensive if you do it properly...not just dodge it.

Nonesense.
I'm at 196ish with an unconventional cam set-up.
I can vreak 200 with 268/258 but it won't pass the MOT emissions test....so I don't run it.
I even run a Cat.
So, 200 BHP before ITBs, on a standard compression bottom end...215-220 on ITBs when mapped correctly.
Go for high compression pistons and you are up around 230 BHP and add a steel crank and 8000+ rev limit and you are up over 240 BHP.
All NA...
It'll be more expensive than going FI for sure...but it can be done.
Several 16vs over on Club GTI are running 230+ BHP reliably...
