Well since we are looking for FI for our cars I think I may have found something that works. CAPA makes a turbocharger for the Holden VE alloytec 3.6L which is the same engine as our LLT. This is the first kit of any kind for the VE engine in Austraila. The set up looks the same from the pictures of our engine bay to theirs. I think the only problem would be the frame design, I'm not to smart about how much that would take to do. I asked my neighbor who built engines and drag cars (before joining the military); he thinks it is a very workable solution. As far as tuning goes I talked to Vince@Trifecta and he said that I could put it on and then datalog. These logs would provide the nessecary info for the car to be tweaked to run optimally. For the price which is AU I think it is a fair price. Current rate is 1 US dollar = 1.1431 Australian dollars. This is the link:

Opinions?
