I’ve a road only Sunday Driver NC with just over 40k on the clock. I considered both Turbo’s and Superchargers before opting for the BBRGTi Super 200 conversion and their stainless exhaust upgrade (keeping the manifold cat option) last year. Bilsteins replaced with Tein Flex Z Coilovers, ARB’s upgraded with adjustablle links, bushes all poly and brakes upgraded to Wilwood with slotted/drilled rotors. It goes really well and stops incredibly well. Alleged power is now around 212 at flywheel, still getting 43+mpg on a long run. What’s not to like? My Hilux is a chipped diesel burner… that’s the home of turbos! My wife’s CLK Merc came with a Supercharger (Kompressor), far more appropriate for gasoline engines but noisy and expensive for an MX conversion. I’m really happy with the BBR conversion.
I’m having my NC done at BBR as we speak - Turbo Charge No 1 - plus new suspension. So cannot say at this stage how it all is but given the costs involved I’m expecting a vast improvement in performance.
I’m pretty sure you’ll get one.
My NC1 is turbo’d to beyond 300 horses and it’s obscenely off the scale of a performance improvement 
I ride a 2007 Fireblade, nowhere near enough mind and a 2L NC seems like it’s stuck in mud as a comparison. It’s the sensation of speed I suppose when your exposed as I rarely drive with the roof down.
The current issue (October 2024) of Soft Top Hardtop has an interesting article about BBR and their turbo and supercharger offerings.
I’ve just acquired an ND with the BBR Super 200 kit, having had a supercharged NA with similar power levels until a couple of years ago. In the meantime I’ve been driving exclusively electric cars.
My first thought was how gutless the S200 feels below 4k revs, compared to an EV which gives it everything from standstill. Once I readjusted and realised that it isn’t a 0-60 queen, but something that’s more focussed on high-rev power and responsiveness, I think 200ish bhp plenty for giggles on the roads I drive on, and a lot more fun than the 420bhp daily.
