A 700hp+ 6.0L LS engine owing around 6k USD powered this rather porky 4720lbs (2100kg) chassis to 2nd place in the GTT @optimabatteries Ultimate Street Car Invitational at @semashow. Build wise forged @MAHLEGroup pistons and @Lunatipower connecting rods are used along with @KingBearings engine bearings, ported LS3 head and aftermarket cams. The twin @BorgWarnerCorporate Airwerks S257 SX-E run around 13psi but there is room to go up to 20psi on occasion thanks in part to the use of an E50 flavoured ethanol fuel blend.
A @haltech Elite 2500 manages the engine with an I/O expander to increase sensor inputs for a well set up and nicely prioritised engine protection strategy. This Nissan is AWD with the use of a TR6060 mated to a transfer case from a Chevy Blazer which gave Stephen an easier job of using the likes of a Y62 Patrol rear diff with that rear end seeing 70% of the torque split.
The LS retains a wet sump, however, it has been modified and an Accusump is fitted for extra insurance and with essentially only @vikingperformance2574 Berserker coil-overs fitted there are plans to upgrade much of the suspension components in the future to remove excess compliance as well as a focus on weight reduction.

096: What’s It Like to Win a Round of the WRC?

Have you ever dreamt of climbing to the very top of your chosen motorsport and beating the world’s best? That’s exactly what Hayden Paddon, this week’s podcast guest, has done. As a past WRC round winner and current European Rally Champion, Hayden is a wealth of knowledge on all things rally, and spends some time in this episode talking through us through what life is like at the highest levels of the sport, what the future of rally might look like, and much more.

Born in a little town in the South Island of New Zealand, Hayden Paddon was introduced to the world of motorsport early thanks to his rally-driving father. Racing karts and rally events growing up, Hayden went from strength to strength before claiming the first of five national rally titles in 2008. Hayden then burst onto the world stage, becoming the PWRC world champion in 2011, and soon found his way into the big leagues with the factory Hyundai WRC team, claiming a hard-fought win in 2016’s Rally of Argentina.
For any driver outside of Europe to get a seat in a factory WRC team is impressive — let alone a round win. It sounds like a fairytale, but the reality is of course very different — it’s been far from all rainbows and unicorns, and Hayden opens up in this episode about just how hard the journey to the top is. And then staying there? Well that’s even harder still.
Hayden talks us through the various machinations, politics, and extreme levels of pressure at this elite level of motorsport — and this includes some really good advice around getting and, more importantly, keeping sponsors.
These days, when he’s not dominating the European Rally Championship, recently becoming the first non-European to win it, Hayden spends as much time back home in New Zealand as possible, developing his own take on the possible future of the sport in his Hyundai Kona EV rally weapon. Hayden breaks down the build, explaining how it all works and what advantages and disadvantages an electric vehicle has over the traditional ICE-powered rally car.
This episode provides a fantastic look inside the world of WRC, covering everything from the insane stress of leading a rally with a seven-time world champion only two seconds behind, to how a co-driver and driver relationship actually works, and much more.
*NOTE* At the time of recording, Hayden was yet to secure this year’s European Rally Championship.

097: Building a SEMA Standout With Cheap Tools & the Internet.

The Toyota 86/Subaru BRZ platform is extremely popular in the enthusiast market for plenty of reasons. It’s simple, it’s rear-wheel-drive, it handles, it’s cheap — and there are few platforms out there that have the kind of aftermarket support that the ZN6 has. This is all to say that building one of these cars to a level where it stands above the rest takes something a little special. Cam Cocalis, this week’s guest, knows this all too well, having built one of the most impressive 86s out there, and one that was good enough to find its way into the top 12 of last year’s SEMA Battle of the Builders competition.

Cam has built something pretty special. It’s one of the wildest ZN6s on the planet with a tube frame front and rear end, expansive cage, wild LS3 powerplant, custom cantilever suspension, and much more. The best part? Cam is only 22, and everything he’s done to this car — design, fabrication, paint, wiring, and more — were skills that he learnt himself using the power of the internet.
In this episode, we talk to Cam about how he became obsessed with the ZN6 platform in his teenage years (which wasn’t that long ago to be fair), culminating at 17 years old when he bought this very FRS as his first car. With Cam’s other main interest being art, he was able to transfer his creative side into the automotive world. We then jump into a full build breakdown on the Scion itself, in which Cam takes us through the whats, whys, and hows of the car. This machine went from your typical Rocket Bunny bagged-on-big-wheels 86 build to something worthy of SEMA glory, so there’s a lot to cover.
Cam also discusses wiring, design, and fabrication at length, covering his ethos behind many of the choices he made on the fabrication side, as well as a breakdown of all the tools he uses in his home garage — the total cost of which might shock you.
This episode shows you that you don’t have to be a professional in the industry or have the best gear in order to build top-level vehicles — you just need the right ideas, motivation, and a healthy internet connection. Let this conversation with Cam Cocalis provide the inspiration you need to get started.
