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...
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!...
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!
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'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...
