Porsche LS3 Wiring

Wiring the Porsche LS3, perhaps the most daunting of tasks was not to be taken lightly.

LS3 Wiring Harness

Wiring the engine with the GM performance universal wiring harness was very painless and simple, with each connector properly labeled.

However getting the GM electronics to talk to the Porsche electronics was a task in itself. To bring life to the factory Porsche LS3 gauges and other chassis powered units and devices, we had to strip down the factory Porsche engine harness and adapt the original sensors to the LS. This process ensured that vital information could be communicated to the car itself as well as the important task of starting the Porsche LS3 with the starter signal and alternator power. Although there are still warning messages as expected, we were able to get full function of the factory gauges, tachometer, water temp. and oil pressure.

Porsche LS3 Cooling System

There are many items to consider in a Porsche LS3 swap, and the next item to consider is the cooling system. With the fuel system sorted out utilizing a nice set of Holley fuel rails and custom lines, we could begin adapting the Porsche LS3 cooling system. Although the routing of the Porsche LS3 cooling system can seem a bit “complex” it is fairly simple and utilizes most of the stock hard pipes.

We opted for the Renegade Hybrids electric coolant pump and front adapter plate to optimize space constraints. The rear-most hard pipes were replaced with flexible hose supplied with the kit to adapt to the stock remaining Porsche system.

SEMA 2015 – Our Top Picks

Team Haute AG recently got back from a week of sightseeing and networking at SEMA 2015 in Las Vegas. For those who have never been to SEMA or are unsure of what the show is about, Its basically your local car show multiplied by 500 times, and millions of dollars worth of car porn shoved in your face faster than you can say Olé!

The 2015 SEMA Show drew in over 60,000 domestic and international buyers and exhibitors. The show is segmented into 12 sections that include categories such as performance parts, tires, rims, racing parts, suspension, brakes, as well as a new products showcase displaying innovative and new products in the industry. Not only that, but the show also provides attendees and exhibitors with demonstrations, seminars, and networking events.

In fact the show was so big after going every day for the entire week, we still did not see it in it’s entirety! There was many notable builds at the show from heavy hitters such as Liberty Walk, RWB, Rocket Bunny, Accuair, Vorsteiner, DUB, OS Giken, and so many more. The magnitude of it is almost daunting. Just when you think you’ve seen enough, you round the next corner or enter the next convention hall, and the same overwhelming experience starts all over again. The team here at Haute AG took it upon themselves to allow the sensory overload to take place, so we could bring you the vehicles that we chose as the highlights. We hope you enjoy, and feel free to disagree or agree in the discussion section of this blog. Without further ado, Haute AG’s Top Picks!



This showstopper was built by Bulletproof Automotive in conjunction with Varis. Featuring a full Varis widebody, with custom split windshield and custom rear buttress to give it a speedster look. A truly amazing build.

This Superstreet magazine cover car is no joke, and is one of the best examples of a Supra that we have seen. The owner spared no expense from the custom V-mount radiator with custom ducting, to the BBS motorsport wheels and the Precision 6667 turbo, this car boasts upgrades that most people dream about.

Amazing clean build by Jon Sibal and RWB.

We saw a few examples of these at the show, and it really seemed to be a love or hate thing for most people. On our side, we loved them. Aggressive, American styling cues up front, blended into a clean, curvy, bumper-less tail end made for an awesome looking car. Let us know what you think; Love, or hate?

BMW E46 M3  

This car immediately caught our attention. This was the first E46 to feature the new Rocket Bunny kit. The car also features air bag suspension from Airlift, as well as a blown LS engine. Very cool build.

This is one of the cars during the show that attracted so much attention, but nobody really knew what it was or where it was from. Unique styling, aggressive lines, and a name that very few people recognized really set this car apart. We immediately knew what it was, as one of our own happen to own a slightly modified G35 coupe, and have priced out the kit previously. But, to see it complete was simply awesome.

As if this car needs much of an introduction or an explanation as to why it made it on our Top Picks list. To see this car in person, it was pure automotive perfection. It was difficult to get a clear picture, as a crowd was always present around this work of art.

Another widebody stunner was this awesome Porsche 911. These guys went all out in making the biggest booty 911 we saw at the show. The body lines were perfectly blended, and pictures don’t do justice as to how much width they added on to this beast.


Porsche Targa - 1



To our Aussie friends and followers, this may not seem so interesting. But for the rest of us from North America, this was a pretty cool car to see make it to the show. A company based out of Texas imports and makes these fully street legal for our market. From the airbags, to DOT approved glass, bumpers, and restraint systems, these guys really appreciate these vehicles and what it takes to make them street legal for enthusiasts. Worth a cool $75,000 USD to you, or not?

We had to share this, simply for the craftsmanship that went into this paint job. The depth and detail was just phenomenal. We looked over the entire vehicle, and were hard pressed to find a single flaw. We can appreciate the man hours something of this caliber takes.

The RWB display at the Forgeline wheels booth brought tons of attention from the crowd as well as media. All the latest RWB cars were on display, ranging from Porsche 930’s, 964’s and 993’s. Truly an impressive display!





This car was probably one of the most famous builds from SEMA 2015. In fact it won the Need For Speed award for best build, and will be featured in their upcoming video game. This car has gone through several iterations since the owner purchased it in 2007. The current iteration boasts a mix of rat rod and motorsport styling and engineering. This car was originally a BMW E38 sedan, and was custom built on a tube chassis with Group 5 motorsport widebody and Porsche 935 motorsport wheels. The car features racing technology, from the chassis to the engine to the suspension, and brakes. Truly a one of a kind build!

There was so many wide body Nissan R35’s at SEMA this year, it was hard to keep track! This was one of the few that stood out. The combination of metallic purple paint, mixed with the Liberty Walk kit, and air bagged suspension and aggressive offset deep dish wheels made this car really pop!

Another perfectly executed Liberty Walk and Airrex collaboration on this stunning Ferrari 458. This car looked great from all angles, especially aired out. Not only that, but the owner is Canadian!

It was extremely difficult to get pictures of this car, as it constantly drew crowds of people. This GTR have air bag suspension, and an Aero Monster widebody kit, and came straight from Japan. But the real head turner was the out of this world hand engraved metallic paint!

Really like the Rocket Bunny kit on the E36, really compliments the body lines well.

This Datsun was so clean it looked like it rolled off the showroom floor. But the main show piece of this car is the engine, featuring the legendary OS Giken built TC24-B1Z twin cam cross flow cylinder head. This built L28 produces an amazing 370 n/a horsepower!


Datsun 240Z Datsub 240Z - Engine



This R8 was just so clean, built by Boden Autohaus, Accuair, and Prior Design.
