After several confrontations on the street and on the track, Williams decided to tear apart the daily driven EVO III and begin a complete rebuild. First to be addressed was the upper headwork. The newly upgraded parts consisted of a full Jun Auto mechanic lineup. Using a set of Jun camshafts with 10.8 degree intake/exhaust lift and 272 degree intake/exhaust duration mated to Jun adjustable sprockets for fine tuning. Jun titanium retainers, double valve springs and custom head porting was done by Williams' mechanic, Bolton, in search of added midrange and top end horsepower. Supplying the added horsepower is a custom built GReddy 20G turbo mated to a GReddy Tubular manifold. Keeping the ambient air temperature always ice cold is a Blitz intercooler with custom 3-in piping. Spent gases are exited out the rear of the car by a custom 3-in HKS exhaust and down pipe. With high horsepower, fuel delivery becomes a critical factor. Custom 660cc injectors are regulated by a CB Power fuel pressure regulator. The reliable and race proven HKS VPC is added as a 290LPH fuel pump insures a sufficient fuel supply at all times. The bottom end has been punched out using .20mm over JE pistons increasing total displacement to 2022cc. Additional items include an HKS head gasket, Blitz C3 stainless steel air filter, and a Racing Gear aluminum radiator.
Producing a significant amount of horsepower usually means problems for the transmission after a dozen or so launches. Bolton and Reese of Tony's Toys were up to the task of rebuilding the factory transmission to handle the new found power. Included in the rebuild was a completely new dog box of short ratio gears with a final drive ratio of 5.358:1. Aiding in the transfer of horsepower to the tarmac is a "turbo clutch" single plate system by RPS mated to a JUN flywheel. Keeping oil temperatures to a minimum is accomplished with an HKS racing oil cooler system sitting up front.
Suspension tweaking was deemed minor on the Evolution 3 due to its already excellent setup when received from Japan. Using an Ohlins coilover setup on all four corners shop mechanic, Reese, dialed in the suspension settings along with a local shop, Superior Auto, who did the alignment. Aiding in the braking department, Williams opted to use a Ralliart master cylinder, Ralliart steel brake lines and custom brakes to bring the 3150-lb beast to a screeching halt. Keeping in check with traction, 17x7.5 Gold ADVAN RC rims wrapped in Yokohama Parada Spec II on the front and rear of the car propel the Evolution to low 11 seconds e.t.s with trap speeds in excess of 127 mph. With a history of circuit racing done with the Evolution III before being shipped to the Caymans, chassis prepping and safety modifications were carefully executed by the experts of Garage SPL of Japan. Garage SPL is renowned for specializing in high performance components for the SW20 otherwise known as the MR2 in Japan. A Safety 21 six-point roll cage was carefully welded in the confines of the interior for added rigidity and safety. Dark grey Recaro SWII suede buckets now reside in place of the factory seats while door panels and floor carpet has also received a custom upholstery job. Keeping a watchful eye of all engine vitals include a plethora of gauges ranging from an HKS oil temp meter, oil pressure, EGT, water temp and boost pressure gauge. A Blitz ID meter keeps boost pressure at consistent levels while a Pivot A/F meter assures Williams the car is running properly at all times. It's no surprise but you won't find any audio system in this baby. "Gungho" was built to kick ass and take names.
"Our competitors said us locals lacked the tools and skills to build an engine properly. Well we proved them wrong and they should take notice that the car was built entirely on an island as our 'competition' said it could not be done. We proved them wrong and have proven that home built is the best way to go," states Williams. So what does he have in store for his 11-second monster? "Well we have only had problems with the VPC so far which sometimes has a mind of its own. We hope to further fine tune the car and hopefully dip into the 10s soon but as far as now when all systems are GO we run low 11.00 passes all day. The car is a real blast to drive and is a real head turner with the graphics. In truth the HKS wastegate is so loud it scares everyone within a 1000-foot radius." Business has been brisk for Tony's Toys as they have become the main distributors of JDM vehicles in the Cayman area. Shipping multiple super cars from Japan monthly has been a real boost for the business. "When you sell JDM cars and parts during the week and then race the same type of car you sell and win on the weekend it makes for a beautiful combination." If import history is to be documented on the Cayman Islands, Williams and his Evolution III are considered the pioneers that started it all. After two years of completion and 20,000 dollars invested into the Evolution III, it's a proven fact that this car is still the one to beat on the island. As of now, Gungho's best quarter mile times at Drag Wars have been recorded at 11.34 e.t. with driver and extra passenger on board. How sick is that? Gungho is a regular at the Cayman Hot Rod Associations Drag meets and Sunday fun runs on a consistent basis, terrorizing the V8 class. Racking up awards and disgracing the domestic class, Williams currently holds the record for fastest 4WD, fastest 4 cylinders, and fastest street legal full bodied car in Grand Cayman. Next time you plan on vacationing in the Cayman Islands screw the beaches, Mai Tai's and scenic views; make sure and check out Gungho.
