EcoBoost 1.6 Kit

Z Cars Classics Re-Imagined

The 1.6 EcoBoost kit is a new addition to the product range. Sporting 1596cc and Borg Warner KP39 low inertia turbo, being a more modern engine, donor engines are freely available and you are more like to be able to secure a lower mileage engine.


A Lighter Conversion

Revving to 6500 in standard form, the 1.6 engine itself is circa 35 kilos lighter than the 2.0 giving the lighter conversion (on account of the lighter engine) circa 250 BHP per ton. A run of the mill stage 2 map would increase that to 325 and a bigger X-47R turbo and a charge-cooler setup with circa 340 BHP would take the power to weight past 450 BHP per ton. All from a 1.6 engine.

With the standard gearing, you can expect a top speed of circa 120 mph, on account of the drop to 13” wheels. As you might expect this also has the effect of shortening the gearing improving acceleration still further over the donor car amplified by the a circa weight saving of over 300 kilos.

We have moved away from the HSS or ERW seamed tube where we now manufacture our frames from the stronger seamless CDS tubular steel, ROPT510. The rollcage kit has a universal section namely; the roll hoop and mounting loop for cradle, the rollcage and door bars. Furthermore there is an option to have tie-in bars joining the side hoops to the top of our optional front subframe. This element is common to all our Mini kits.

Self Contained Engine Cradle

The rear section is now modular in the form of a self-contained engine-specific cradle for each kit which allows the all the critical elements in the rear of the car to be removed in one-go, such as; the engine, gearbox, rear; suspension and brakes.

There are a number of distinct advantages of having a removable cradle, which are covered under the ‘modular engine cradle’ overview.  The cradle for the 1.6 EcoBoost comes with engine mounts and a sway bar as additional brackets for mounting the ECU, and room for expansion if you were considering future upgrades such as a heat exchanger for a charge-cooling system, a rear mounted intercooler as mounting possibilities for a dry sump or an oil cooler.

The cradle can also have provision for the engine loom within the cradle so the engine loom can be disconnected easily and remain attached to the cradle as it is removed or fitted. The rear section of the roll hoop and frame can also have bracketry for a bulkhead to be fitted and to run a wiring loom.

Engine Overview

The EcoBoost 1.6 litre engine from the Fiesta ST Mk 7 is a new engine option for our modular kit. In standard form, the engine delivers 180 BHP (165 per ton) and torque figures 240 Nm, 177 ft-lb. Whilst initially a 1.6 might sound a little underwhelming, in standard turbo guise the impressive torque figures outgun the K20. The engine at 114 kilos is 35 kilos lighter and more compact than the 2.0 litre. The 1.6 is also circa 20 kilos lighter than the K20.

The engine is widely renowned by tuning companies as being able to exceed 300 BHP without the need for forged innards.  We are currently exploring being able to virginise the ECU to negate having to run a standalone aftermarket ECU.  The appeal of these new turbo engines and embracing the forced induction era – as F1 have done – enables you to get comfortable with a powerful shorter wheelbase setup and be able to pursue higher outputs throughout your ownership.

Furthermore with a decent ECU, switchable maps and tapping into traction and launch control are practical options allowing the driver to extract more from the package being able to approach the maximum.
