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...
When I first heard about V8 swaps into jeeps I was skeptical. I am not a fan of installing things on my jeep that require a lot more maintenance and extra steps to use. After talking with Jeff on the phone he invited me to come up to the shop and see what they do. I was immediately impressed at the welcoming attitude of everyone there as well as the open attitude to have me look around. I took a drive and realized just how well integrated these swaps are. You drive it just like when it was stock. No other buttons to push, no instructions to follow. I brought a 6 speed manual and left with an automatic that looked like it came from the factory on the interior. Tap shift, cruise control. It all works, just MUCH more powerful. That magna flow sound of a V8 and the torque when driving from ...
Being in the off-road industry myself, I am very picky about where my Jeep is worked on. Add to that the major work of an engine swap and you quickly realize that trust in the shop is EVERYTHING! Jeff and the crew are at the top of their game! The attention to detail is unmatched and the quality could not be any better. Simply put... they know what they are doing. Add to that the friendly service and you have a winning combination. Thanks again guys!
In the last 10 months Dixie 4 Wheel Drive has installed 6 Bruiser Conversions LS3 "Do It Yourself Kit" motor conversions. At first we didn't know much about Bruiser Conversions since we are from Utah and they're from Florida. I had heard a few good things about Bruisers, but usually East coast service is hard to keep in touch with. However, with Bruisers it was different. From a shop stand point, we were excited to hear that their motor conversion kit was one of the best JK V8's kits on the market. Since we had done several different Hemi and LS conversions before, we were anxious to install the "Do It Yourself Kit" into our 2015 SEMA build. Once the motor conversion showed up, we were super excited to open the crate up and see the install kit. The wiring harness and front accessory dr...
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...
