Like many jeep owners I set out to build the ultimate go anywhere jeep to provide amazing family wheeling excursions. Initially built was a mild mod JKU, however the anemic 3.6L became the 'weak link' so I sough out an engine conversion. After determining the LS3 as the most optimum power plant, I then began to search for a builder/installer and chose a local SEMA Jeep Builder. As I explained to the selected builder, 'there are 2 ways to do things, the right way and the wrong' no in-between. Unfortunately for me that selected builder had very little integrity and built a very expensive paperweight. After those in the Jeep community found out what happened many stepped in to assist with my build. We began an extensive rebuild, and we chose the industry leader in LS3 Conversions, Bruiser ...
I want to thank the Bruiser Team for turning my 2004 Jeep TJ into a one of a kind LS3 swapped TJ. After a few phone conversations with Jeff going over what I wanted/needed it was an easy decision to send it out to Bruiser. I had originally planned to just do the LS3 swap, but after visiting the shop and hanging out with the guys for the day checking out all the jeeps under construction, my engine swap quickly turned into a complete redo. The Baja style roll cage/tire carrier turned out awesome! The guys at the shop were very helpful in steering me in the right direction on what additional changes I wanted to add to the build. I have had my jeep back for a week now and it drives so much better than it did before with a hell of a lot more horsepower. It’s definitely a head turner!...
I decided to go with the Bruiser Conversions LS3 conversion kit after the turbo on my 3.6 factory engine blew up. I am so glad that I did, the engineering is unbelievable, everything is "plug & play". The engine and every piece around the engine fits perfectly, plus no more turbo lag!!! My friend and I did the complete job of removing the old engine and installing the new LS3 motor in 3 8-hour days. With a turn of the key it started right up and purred like a kitten. After driving it for 400 miles, I changed the oil and then drove it down to Florida, 1500 miles in 24 hours with no problems. Everybody that sees the engine compartment says that it looks like it's from the factory. When I'm asked where I got it from of course I tell them Bruiser Conversions in Cleartwater, FL. I highly rec...
January 3, 2015 I had a LS3-430HP Corvette motor installed in my Jeep by Bruiser Conversions. Many have asked how I like it, how long did it take, what's it like, how was fit and finish, etc. Saturday January 3rd I drove from Naples to Clearwater. Met Jeff at Jeff's Jeep Yard/Bruiser Conversions where I was given a complete tour and filled with a ton of knowledge. Jeff will blow your mind with his passion and expertise! Left the Jeep in Bruiser's hands and returned to pick it up on Friday Jan. 9th. Yes, that is correct - One week for the conversion. And not just the conversion, they painted my rear wheel wells. Needless to say, I was like a kid in a candy store ready for the first drive! I'm pretty particular about cleanliness and was pleasantly surprised to see how clean the jeep was w...
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...
