okay guys, the car finally had its upgraded tune after I added the knocksensors back to the harnness. I also changed the exhaust to the corvette npp exhaust. the xlr exhaust is very restrictive! The car put down 756 rwhp and 787 rwtq. This was with the stock fuel pump and a boostapump. I...

sure, I could help anyone who wants to do the swap. I have the tune worked out for the e67 ecm. This solves a lot of headaches:thumbsup

Interesting thread. I jut put c6 z51 bars front and back. Definately helps with handling. I'm torturing my rear tires with the turbo ls3 right now. I think I can get a 10" wide wheel on the back and move up to some wider rubber.

Basically the C6 corvette is the donor for everything! Harness rewire is about 10hrs of work My entire swap took about 40 hrs of work for a professional mechanic, including building the harness. The xlr is a great car, but the 320 hp the northstar puts out is approxiamately is about 260 rwhp...

The tuner is well known in michigan. He goes by "roadrebel" on the corvette forum. The difficult part of the swap is the electronic parts. The e67 ecm is the same as the corvette ZR1. He had to remove the northstar copmponents and load in the zr1 segments. The car now runs and drives like...

Well, I got a call from the tuner. It took a while to get the zr1 ecm to talk to the Xlr trans computer. It's all good now. Initial dyno results at 11 psi put down 600 rwhp and 650 rwtq. This is through the extremely restrictive stock muffler. Not bad if you consider the stock northstar...

yeah, sure it happened.

I just completed the motor part of the swap. I did how ever upgrade the brakes to c6 z51 rotors and upgraded the suspenion with 6 z51 sway bars front and rear. I want to see how the car drives after I get my new rims. I believe I can get a 10" wide rim on the back. I sort of like the way...

It's funny all of a sudden the people who are concerned about buying on the internet have'nt called me? I will talk to anyone about my motor who is serious! This is a great deal for someone who needs a used motor with no issues. FYI a new alternator lists for over $800. I have started a...

The actual swap took about 40 hrs to complete. removing northstar making a custom engine harness installing ttix c6 corvette turbo kit/ls3 install The planning started last fall after i removed my forged 416" ls3 to have it freshened up. I actually took a while to find the appropriate xlr to...

The installation is complete. All of the electronics are working. The car is getting a final tune this week and dyno! Sent from my iPhone using Tapatalk

Thanks, I bought this car because I have a spare engine for my Corvette. It's been very interesting to Convert the car to an LS3 motor. I'm slowly collecting some unobtainable parts! Sent from my iPhone using Tapatalk

here ya go. Its an awesome sleeper. Not a cheap conversion; but its awesome.:cool:

Hi guys, I am an new owner of a 2009 raven black car. I have some other sports cars; but i like that you don't see many xlr's around town. The northstar was a little tame for me; so it is now a twin turbo ls3 xlr with 750 rwhp.:D:D
