Built In Bali: A Carbon-Clad, Twin-Turbo Cayman S

A full carbon-wide-bodied and twin-turbocharged Porsche Cayman sounds like something you’d see built in Southern California for the annual SEMA Show, but the one I’m about to show you is about as far removed from that scenario as you can get.

This composite-clad and boosted 2008 Cayman S was brought to life on the small Indonesian island of Bali.


When I first saw the car back in 2018, it was at well-known Balinese tuner UKworks Performance undergoing its twin-turbo conversion. At that time, the Cayman’s owner Ferry G. had already fitted an FRP wide-body kit and it was painted in a not-so-subtle shade of yellow. I can vividly remember being blown away by the fact that something this wild was being built on the island. Click here for a short clip of it rolling out the dyno booth.


This was the biggest project that Suyra at UKworks had ever taken on, and he took his time planning out the engine upgrade. While it obviously needed to work from a performance standpoint, reliability in Bali’s tropical climate was equally important, hence why only quality parts have been used throughout. The engine remains internally stock, but the addition of twin Precision 4831B turbochargers have really woken the already powerful 3.4-litre flat-6 boxer up. The setup uses Fabspeed equal-length long-tube headers, Turbosmart wastegates and blow-off valves, and a custom UKworks water-to air-intercooler system.


Fuel comes via FIC 750cc injectors, spark via Beru 911 Turbo coils, and the whole package is tuned through an ECUmaster engine management system, revealing a modest 500hp. To aid cooling there are Mishimoto oil coolers and a UKworks quad fan setup.


At the same time the engine was being modified the suspension and brakes went under the knife too. In this area you’ll now find BC Racing BR Series coilovers, Brembo AMG SLS Black Series 6-pot calipers and Runstop 405mm rotors up front, a Brembo 4-pot caliper and 380mm rotor setup out back, plus a GT3 RS master cylinder. The wheels are a set of custom 3-piece, single-lug BC Forged LE72s in 20×9.5-inch and 20×12.5-inch fitments front and rear respectively.


The pièce de résistance, of course, is the custom carbon fiber bodywork, which Ferry said was inspired by Pagani, Zonda and Koenigsegg. For this aspect of the project he enlisted Zoom Bodyworks & Carbonworks to reproduce all the exterior panels in carbon, a huge undertaking and one that require a massive amount of skill given the exposed-weave finish.


Naturally, the carbon kit is wider than factory, but it was done so in a way to stay true to the Cayman’s original lines. The front hood and rear trunk air scoop were inspired by designs that Porsche adopted on the GT3 RS.


The interior didn’t escape customization either, and like the exterior the execution is to a very high level. Lederpro custom-trimmed a pair of Bride Low Max seats along with the door panels and dashboard, and the center console was remade in carbon fiber. The cabin also features an AiM digital dash, Defi meters in a custom carbon A-pillar pod, and a high-end audio system featuring Audison amplification, and speakers from SB Acoustics and Helix.


There are so many details in this build and I’d hoped to photograph more of them during our shoot, but the weather wasn’t on our side. In fact, we ended up being caught right in the middle of one of the biggest storms I’ve ever encountered. But negotiating the flooded streets of Bali wasn’t a problem for Ferry – his Cayman was built to be used.


Right from the get-go Ferry wanted to create something truly unique, and I think it’s safe to say he achieved that. What you see here is 100% built in Bali, and for that I feel an amazing sense of pride.

That looks a lot of fun


Amazing car and pics, bravo!! This Bali sky is unbelievable!


That storm was an awesome backdrop. Car looks incredible, and 500hp is hardly modest in an actual street car, especially driven in that weather.


I bet this is a lot of fun, though the choice of an auto seems odd given Bali isn’t large. All that said, it’s a peculiar mix of parts, from top tier to bottom rate. Always various considerations in that realm which I get, but odd regardless


Surprised that BC racing coilovers were used in this build from what I understood they are a budget coilover. I recently priced them against KW's & even ST & they were significantly cheaper. Ended up ordering a set as I couldn't justify the additional $ for even the ST's let alone the KW's.
I love the build especially the bold interior.


perhaps they got a deal, or the shop is a dealer, given it also has BC wheels, and all the stuff comes out of Taiwan, so relatively close


Absolute machine, this thing must move differently. Its looks are like a artform and its perfromance is spectacular, love this build, amazing.


Each to their own, as this build must be a bore to drive if you have even a few weeks of having driven similar cars, but THAT BODYWORK. Wow. Much factory look, such knowhow!

Zoom Bodyworks & Carbonworks should be crowned.


As I'm reading this and I see the 500hp part I googled "LS swapped Cayman" and found a video of a Ford Coyote swap into one of these making 424hp and 364tq. (I'm assuming this swap is rated at the crank). The engine costs $14,000

Anyway, the article says the car cost $100,000 total to do the first time around and should cost ~$30,000 less the second time they do it. Which means in reality it's being done for about $40,000-$50,000 before mark up. Not sure if they are including the cost of the car, but what is a Cayman these days?

What I start to wonder is what this guy spent to do this car with twin turbos by comparison. Spare me the comments about LS swaps and blah blah blah. Just wondering if anyone knows what this work on the Porsche side goes for these days. I'd be shocked if it was cheaper.


Any V8 in Indonesia is a rarity unfortunately, importing Coyote or LS probably will cost the same if not more compared to this twin turbo set up due to our exorbitant tax.


Thanks for clarifying Kianonn. That makes sense. Appreciate the insight sir.


If you're looking for Power to $ Ratio, obviously there would be a budget friendly option to make as much or more power. But this isn't what this build is all about. This is a passion project and nothing quite sounds like a flat-6 engine. Put Twin-Turbo it makes all the right noises.

I don't talk costs because it's out of the question, I like to focus on overall build and appreciating the effort any car owners goes through to make their dream come true.


edit: it is whp and wtq just for clarification.


Yummy! Never seen so much carbon goodies on a Cayman before!

Rick, exactly how much weight the car managed to shave?


I'm not exactly sure, I'd say it's probably close to original weight more or less. If you count the turbos, additional cooling system, interior goodies and sound system. Which is still rather impressive!

someone buy my GRMN iQ please


The cut in the rear bumper is too big, i think if there is more "body" (or some grills maybe) it would be nicer. But man the overall body work is amazing.


Light in the engine bay like that. Many many yes please <3


All that money and none of it spent on teaching the driver how to use his left foot.


It's not even a PDK.
