Are you top swapped right now? You said a '06 GT but you are ordering a MPS (I assume Modular Pulley System, but I could be wrong)

If that's the case, you have all the main parts. I purchased a 27K L26 that looked like it was pulled from a showroom floor car. I have pics in a thread around here somewhere if you want to see 'em. But I have a a little under $3,000 in my build, and I had to buy the top swap and had the heads worked...I went with a N* also because it came with the top swap and I plan on upgrading eventually to a Gen V and intercooler. So there's more of a savings for you. You can do it with a new low mileage L26 for $2000 I'm sure.
