After making some researches online, I decided go with Performance Works' Turbo Kit.

I talked to Nick on the phone and he was an extremely helpful guy. He knows what he is talking about. You can basically ask him anything you want to know.
He gave me an excellent deal (I am sure he will give you the same deal as well, just give them a call) and he said all the parts will be ready in less than 3 weeks and they can do the installation in two days and that is because they will be tuning the S-AFC for the new turbo. I can't wait to get everything installed and ready to go.
He said he will tune up my car when I go to their shop in Pennsy.
So far, I am really happy with the customer service. Pictures of their turbo kit installed on their Evo looks just great and shows the top notch quality.
If you guys are considering a turbo kit, I would say go with the Performance Works.
The Customer Service is great! Ask for Nick when you call the shop and he will answer your questions and help you on the phone all day long if he needs to.

I just wanted to share my thoughts about their service since they are new to the Evo forums.. and I will update you all once my turbo kit is installed...

Thanks!
