Speed Perf6rmanc3 SPEED PERF6RMANC3 is dedicated to pushing the Mazdaspeed 3/6 and Ford EcoBoost platforms to their full potential

SPEED PERF6RMANC3 was started by two Mazda master technicians who shared the same passion for pushing the Mazdaspeed 3/6 platform as far as they could. Our day to day experience of repairing the entire line of Mazda vehicles has given us exclusive insight into the inner workings of the MZR motor that no one else could ever learn on their own. We have built 20+ motors that are supporting MOST of th

e community’s highest HP cars. We strive to use only the best parts out there and when we find a part to have a weak link, we go back to the drawing board to redesign it to handle more HP and more abuse in order to push the limit even further. We work very closely with a select few machine shops that are owned by world renowned engine builders. This gives us the ability to both ensure the highest quality machining is met and to improve on every motor we do based on 75+ years of combined experience in the racing industry. We stand behind everything we do and nothing is more important to us than customer satisfaction.

This one’s got a hefty 6870 turbo setup alongside it too from TunePlus.

Arguably the best manifold.
By far the best looking one.

The JMF Billet Intake Manifolds aren’t just eye candy either, these manifolds have proven themselves on some of the nastiest builds out there while completely transforming the engine bay appearance.

Available for:

• Focus ST / RS
• Mazdaspeed 3/6

Options available for both:
• Port Injected
• Non-Port Injected setups

We currently have ONE Focus ST/RS Port Injected manifold in stock in the raw shiny billet finish ready to go 👀

Want to take it a step further?
We can also option it with our full Port Injection package featuring the Motiv Reflex+ controller for complete supplemental fueling control.

If you’re building a serious setup and want performance while making the bay look insane… this is it.

Tired of clenching your b***y every time you go WOT?
Scared of slipping timing once you start making real power?

That factory friction setup isn’t meant for big power… and when it slips, it’s game over.

Upgrade to a Keyed Crankshaft Kit and take that weak point out for good.

• EcoBoost 2.0L – $700
Built for guys pushing past stock limits that want peace of mind at WOT

• EcoBoost 2.3L – $790
Perfect for Focus RS / Mustang EcoBoost setups making serious power

• Mazdaspeed 3/6 – $875
Eliminates the common crank gear slip issue on high horsepower MZR builds

This isn’t a “maybe it’ll hold” mod… this is a fix the problem permanently mod.

Stop gambling your build.
