You may want to consider starting off with 5-7psi on a turbo that can be turned up (GT28 etc etc) so that the car can grow with your budget. You are going to have to do the fuel management in one shot anyway and that is expensive and time consuming enough! My advice is price out the fuel stuff and turbo stuff and dial it in at 5-7psi. If thats not enough then price out the 10-13 psi stage and some internals, or if you find yourself with extra cash and downtime go up to the fully built block at that point! good luck!

All this is very good advice. A stock LS engine won't generally take more than 7psi stock and thats not considering what kind of condition/age the engine is in. I generally support using Hondata for all your tuning needs. Its something you can adjust yourself, and a lot of tuners support it. On top of that its not too expensive. I have heard of people using Chrome and Uberdata for their tuning needs but I don't know the specification of those applications so I can't say if they will meet your needs or not. If your looking for just a little boost on a budget then I would stay away from kits necessarily. With a little creative thought and unique sourcing one can find the parts needed for a turbo setup quite easily. Check out the guys over at homemadeturbo.com They know their stuff and know where to get the turbos and parts that fit on a budget. For example, instead of purchasing a new GT28 or whatever you could source a stock turbo off an older volvo or DSM and use that efficiently until you have the money to crack open the block. Also stock turbos from the subaru WRXs are fairly easy to come by as everyone wants to upgrade to the STI turbo.
