Re: LS7 swap.
I understand what CC is saying, but I have one thought to interject into his assertion. Aftermarket equipment that is developed by third parties for a multitude of audiences, in my opinion, is completely different from transferring components from what is essentially the same vehicle. No I am not an expert on the XLR, but I have some very good knowledge of late model vehicle components and their respective interactions. In the case of the sound system the different IO operations bridge several different systems, steering wheel controls, HUD etc. If the target peice was not engineered with this consideration in mind then one could expect to have some serious issues to overcome. In the case of the XLR / Corvette they are essentially the same vehicle. Moving one component from one to another should not present that type of issue. I understand that it would be a little more complex than a bolt on operation, but I truly believe it doable with relatively little pain and lots of money.
If you really like building a car on your own, why not buy a used XLR-V, strip it clean [engine, transmission, electronics, et al] and start from scratch. Then you will know for sure what you have and how it works. Might be more fun.
So, did you put an LS motor in the XLR or not? I own a 2005 XLR and would like to get more hp with an LS rather than a Northstar. I talked with a Cadillac dealer and they will not take this task on. I live in Virginia Beach and am seriously thinking of going to Fantomworks and talking with them about this project. If too costly, then, I will sell the XLR and search for a CTS-V Coupe to satisfy my hp need.
The four-plus years this thread has languished silently might be a pretty good answer to your question.
The fact that a GM dealership won't Frankenstein an XLR is hardly surprising.
Several single-digit posters have generated all motion and no movement regarding this (interesting) topic. They get an XLR, become giddy, join the forums, verbally ejaculate, become rhetorically flaccid, then dissapear.
Anyone can talk; Executing a challenging LS engine swap takes a little more effort than typing.
I've seen one example of an XLR that was gutted and turned into a dragster, (it was subsequently destroyed) but nobody has yet to post details and pics of an LS engine swap. For the time being, an LS-equipped XLR is like Nessie, Bigfoot, or UFOs. I can accept their possibility, but not their existence without definitive proof. At least there are grainy pictures of the former, while none of the latter. . .
I'd love to see it be accomplished, but when it's all said and done, a modified XLR-V is the most practical, cost-effective method to keep the car luxurious and fast, while retaining full functionality of the integrated systems that make an XLR so cool.
Knock yourself out. Expend resources to boost our ailing economy. If you can make it happen, you will become an XLR legend. The world watches . . . And waits. Will you be a single-digit poster, or Multi-digit boaster?! Time will tell. Good luck!
On a someone-finally-pulled-it-off note, another owner has successfully modified the infotainment system to today's standards. Major kudos, mad props, and all that congratulatory stuff.
Since my last post, I have exhausted my research on this topic and this is what I found out: 1. Yes, an LS- motor can replace a Northstar in an XLR; 2. Since the LS ECM will not talk to the other controlling modules in the car you will lose the following: a. Cruise Control; b. Traction control; Body roll control module won't talk to the LS ECM so if Magnetic Ride equipped, there may be an issue. So, the trade off for more power from an LS motor, takes away all the 'creature' features that make the XLR a nice car to drive. My friend obtained this information from a GM Engineer and a Detroit Speed Engineer. Their advice as yours was if I wanted a Cadillac product and more HP, I should think about moving to a CTS-V and they recommended a Coupe. So, after owning a 2005 XLR (Xenon Blue with Champagne Interior) from 2007 to 2015 and 25,352 miles on it at time of trade-in, I graduated to a 2013 Thunder Gray CTS-V Coupe with 3,289 miles. It is quieter on the Interstate and the ride is not as stiff as the run flats on the XLR. Thanks again for your time and advice. I hope everyone that wants to do this type of swap will have the good fortune to find out the things I did. Since the original posting is so old, not many will want to read it.
