Rising Sun - Hardcore Cayman

The Doc

Recommended Posts

From the land of the rising sun has emerged a 987 Cayman like no other.  It is often phrase head in Cayman circles "what if Porsche put the GT3 engine in a 987".  Well, now its been done, and this time in a package which appears so thoroughly executed.  


Allow me to introduce M’s Machine Work's Cayman GT3.

The car is the work of Takayuki Mizumoto, a Japanese motorsport engineer.  Mizumoto-san is the proprietor of M’s Machine Works, an outfit that designs, builds and manufactures bespoke components for the Super GT race series, a race series for road-going cars made famous for being incredibly fast.  This latest project car from Mizumoto-san however is not a race entry, it's a road legal track toy - for pleasure!!  



"what if Porsche put the GT3 engine in a 987"


Taking a closer look at the spec of this hooligan Cayman the obvious place to begin is the engine, which in fairness needs very little introduction.  The Mezger derived lump is from a 997 GT3 Cup car providing c. 450bhp.  OK, so it has been done before, we know Jurgen Alzen Motorsports entered a similar set-up in the GT4 series, but they were not road legal...and they didn't look this good!  The transplanted engine is kept alive using a Motec ECU and the engine is mated to a manual 6 speed transmission with a custom LSD.  One hopes with some form of adjustment to the final drive.  





Cosmetic surgery has been performed quite extensively making the resemblance from a base 987 quite distant.   The front end has been reconfigured with 997 GT3 facelift but with a few custom teaks and downforce enhancing upgrades including a carbon fibre splitter, oversized dive planes and a more aerodynamic flatter floor.  Mizumoto-san has increased the track by some noticeable margin on the car, the result is a car requiring some rather extreme wide arches.  The rear of the car is barely recognisable as a Cayman of any known species with hardly any bumper to speak of, a rear wing that quite honestly is super-massive and a rear diffuser spanning nearly the whole width of the car.  This an extreme make-over, but one which has genuine performance enhancements at the core of its design.

The interior of the car has not escaped the motorsport inspired treatment either, a race spec steering wheel, fully fitted roll cage, air jack, poly windows and a whole other heap of goodies adorning the stripped out cabin again point to this being a seriously specced racer.

Finishing touches include the lightweight Volk wheels, super sticky Advan tyres and plenty of vinyl die-cuts plastered across the car.  This is certainly an impressive machine and track times posted by Mizumoto-san are even more so.  With a 100kg weight saving over a GT4 and plenty more power you'd hope so though.  


There are rumours of a MkII car which will feature a GT2 engine instead of the naturally aspirated GT3 motor, we await news...
