Skuz­zle read­ies 450bhp mk1 ‘daily driver’

Total MX-5 - - NEWS -

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.
