I've got a 430hp LS3 installed in my 2012 JK and I love it! I'm running 37's on one ton axles and the factory V6 was not enough to move the thing down the road. I found myself not wanting to drive my Jeep anymore... Until I found Bruiser Conversions. Their LS3 conversion woke the Jeep up and turned it into a monster!!! I daily drive my Jeep now because I enjoy driving it so much. It sounds and feels amazing. The most fun part is red light racing little sports cars and seeing the look on their faces when you blow the doors off them in a lifted Jeep. The most amazing part of the conversion, however, is how it just works. All functions work as they did from the factory, there aren't any funny warning lights or messages on the dashboard. The A/C blows cold. The factory tap shift works. Noth...
To make it short and sweet, Jeff and his crew over at Bruiser Conversions hit a homerun with their LS conversion for the Jeep JK! I personally believe it is by far the best LS conversion on the market. When we here at PSC Motorsports decided to do a V8 swap in one of our new 2015 JK's, I knew I wanted a LS3. We have done the Hemi thing in the past and this time I had my heart set on a LS3. So when it came time to pull the trigger on the project we hooked up with Jeff Garland and Bruiser Conversions. He has come up with a very different approach to the JK / LS swap, and it is ingenuous. Fellow off road industry insiders had been telling me how well the Bruiser Conversion works and well, I am a believer! I freaking love this Jeep and it's all due to the flawless LS3 conversion. The crafts...
Savvy Off Road is know for their winning KOH Jeeps and lightweight armor. When we chose to install a LS3 in our 2014 JK Unlimited, there was only one choice. Bruiser Conversions! The LS3 conversion for the JKU is the best available kit. No double computer or harness to take up space and maintain. We have seen our fair share of double harness kits leave the owners very frustrated. The batteries would go dead on them frequently and not all of the features of the JK were available like OEM. The Bruiser Conversion on the other hand uses the OEM Jeep computer and transmission so everything functions like it is from the factory except you now have 430+ HP. We install the best of the best in everything we do. Bruiser Conversions is the only way to go!
No Jeep is the same and everybody likes to customize his or hers own. As so did I. I started with a used black stock Rubicon unlimited out of 2012. The reason for this was the new transmission that they introduced that year. After the first upgrades (bumpers, lift and tire's) it was time for the more serious upgrade, an engine swap. When you are pulling a wrangler over the mountains in Colorado with a stock 3.6L V6 engine, you get the feeling you are Fred Flintstone. The nice 2.8L CRD would be a nice help with that, but unfortunately you can only get those in Europe. What to do? We all love the big V8's. So the next trip would be to your local Jeep off-road shop and swap that stock engine for a nice 5.7 or 6.4 Hemi. Now just wait there for a moment. Let's browse the internet for a momen...
I have known Jeff for 7 years, so when it was time to build my 2014 JKU into the LEGEND2.0 with a LS3 480 HP hot cam he was my first call for engine swap advice. Being 10 hours apart, I planned to have the work done closer... but when Jeff said they could do an LS swap in a week, I had to put it to the test. Anyone that could swap that fast with confidence clearly has their ducks in a row. Sure enough, a week later I was headed down to pick her up! Jeff walked me through the numerous custom machined components proprietary to his conversions; some serious hardware! His engineering, his team, and their overall commitment to quality all came through. Doing burnouts as soon as I got back to Charlotte! Thanks Jeff!
