Skuzzle readies 450bhp mk1 ‘daily driver’
Winchester-based Skuzzle Motorsport is in the throes of developing an extreme turbo installation for a mk1 that the customer is planning to use as his daily driver. The goal for the conversion is 450bhp and 9000rpm, the former comparatively easy to achieve, the latter perhaps slightly harder work…
The engine upgrade is extensive. It has a billet crank – complete with Skuzzle-logoed billet main caps – Carrillo rods, Supertech Performance pistons and slightly larger bores, 1mm oversized valves, Inconel exhausts valves that are hollow and sodium-filled, and a set of Kent Cams camshafts to a similar spec as rallycross cars from a few years ago. Davefab has been commissioned to produce custom inlet and exhaust manifolds to Skuzzle’s specification and, of course, there’s a turbocharger, a Borgwarner EFR6758 unit.
Ensuring that all these components work in harmony is an Ecumaster EMU Black ECU that enables the car to have a full canbus digidash: the car’s also fitted with a plethora of extra sensors to provide this sophisticated management system with as broad a spectrum of information as possible. As the engine is likely to have quite a thirst, the fuel lines have been uprated with bigger bore aluminium items, complete with a high-flow, motorsport-style inline filter.
For the moment the car is fitted with a six-speed manual gearbox and a Torsen diff, but that’s only while the engine is being run-in on low boost. Later it’ll get either a BMW ’box or a sequential setup from Elite Racing Transmissions.
Understandably the mk1 has been subject to a raft of other modifications. Wilwood brakes, for instance, with six-piston calipers on the front, four-pots on the rear. All-new subframes and arms. Meisterr suspension. And GC Fabrications has built a roll-cage, as well as sorting out the rust in the bodyshell and tubbing the rear wheelarches.
Total MX-5 is hoping to run a feature on the completed car once all the development work and testing has been done.
