Anybody taken the 160Bhp MX5 Sport tech to 200Bhp?

[daveknott5]

I've heard that 200Bhp is relatively easy to achieve by changing to a four throttle body, uprating the camshafts and the addition of a remap. Companies like Raceline and Minister Power can do it - has anybody actually done it, how much did it cost you and were the results worth it?

[hornetrider]

Nope but just gonna watch this

Am I right in saying the NC MZR engine is the same as a Ford Duratec but with VVT.

[daveknott5]

yes it's a Ford Duratec unit I believe and is also used in the Caterham Roadsport, R300 etc

[MX-5 Lazza]

I'm sure I heard somewhere that the Ford Duratec was actually based on the Mazda engine!

The makes more sense of the Cosworth supercharger as I always connect Cosworth primarily to Ford engines.

Some info for those interested - price might put you off!


Thank you for your enquiry.

Whilst we have great deal of experience and success tuning the Duratec 2lt engine, and circa 200 bhp , is a conversion we make, along with the throttle bodies you mention we normally fit updated camshafts as well.

Also, on our Duratec conversions we use an after-market ECU with a bespoke fuel and ignition map.

Therefore the conversion can be made but will include the above and be priced accordingly, from £3000.00 + Vat Subject to the condition of the base engine etc.

We trust this assists you.

That doesn't seem bad.

And Lazza, you're right, the MZR engine is actually what a Duratec is based on, rather than the other way around.

That's about the same price as getting similar power from FI isn't it?

[hornetrider]

BBR S/C is 5k + VAT for 245bhp.

That's more than just an SC though isn't it? I thought that was a full car refresh...
MP62 from Moss would be around that + fitting.

It's not the Mk1/2 we're talking about though, Mk3+ is a completely different kettle of fish and if you want an NA tuned engine it's always relatively expensive to get decent reliable power.

[hornetrider]

No not for the Mk3 Lazza - that's for the S/C and all the gubbins.

That's what my post was looking towards - £3k for 200bhp from the NC engine kept N/A versus £3k(ish) for 190bhp from a NB engine gone FI. Tuning the NC engine seems pretty good value imo!

Ah right, I thought you meant the Mk1 kit

Except 190bhp is a 50bhp increase over 140bhp compared to 200bhp being a 40bhp increase over 160bhp. Percentage wise it's less value in terms of bhp% increase

[Pondered Scrotum]

Less value maybe than the NB FI example I gave but still good I reckon when you take into consideration the cost and (documented although recently reduced) risk of the supercharger kits for the NC as well the normally much higher cost of N/A bang-for-your-buck...
