RE: New BBR Mazda MX-5 turbo kit

[Itsallicanafford]

Ah, that colour scheme reminds me of my old NA...



...the BBR kit will make the ND a total weapon...

Undoubtedly, it makes me very happy that among all manufacturers just sticking turbos onto their engines and calling it a day, Mazda still sticks to squeezing more out of a screaming NA lump.

I dont know why anyone would go for the Fiat 124 with its turbo engine when you can get the mazda with an NA lump

Whilst I admire all the tech in the skyactive engines, how did they only manage to get 160bhp out of the 2.0 lump?

VW/Vauxhall/Nissan etc were all getting similar power out of 2.0 16v engines back in the 1990's, and Renault, Honda have made engines with way more than 160bhp... (albeit while using more fuel if the Mazda figures are to be belived). Why didn't they aim for more power?

Fuel use aside, didn't Honda cite emissions regulations as a reason from dropping the old VTEC screamers? I would hazard a guess emissions play a part for Mazda also. Beyond that, perhaps they thought 160 was the perfect balance for such a car.

This or a GT86 with some Abbey SC and damper mods?

Emissions. Cant get 200+bhp fomr a 2.0 these days and easily keep within euro whatever. NA engine power has been dropping so everyone else has been switching to turbos

"A single-scroll turbo was also rejected; the 4-2-1 exhaust manifold of the MX-5 is very complex, to exploit exhaust scavenging technology, but a single-scroll turbo creates a lot of back pressure and lacks any potential for exhaust scavenging."

I don't see what relevance the std manifold has, when the conversion uses a totally new manifold anyway. I smell something.

The gt86 manages 200 from 2 litres with a combo of direct and port injection. Rumor has it the "torque dip " is entirely emissions related.

Emissions regs nonsense strangles the engines, if you put the stock Mazda manifold next to the aftermarket product BBR supply for the NA Super 200 coversion the differences are shocking. You don't need to be an engine builder to understand how the engine will breathe more freely with the aftermarket product.
