350z want 2 modify engine 400+ hp

[apiafo]

Well officaly in the Nissan Family, i just purchased a stock 03 350z 6 speed, i purchaced this car because it has a hell of a look and the highest hp availible uncompressed, in a afordable package, now i want to compress this engine with 400hp or so, ive seen hundreds of setups on internet but i am looking for a kit that is complete, with a certain support from manufacturer, i know that i will need more than whats in a box but what???also a kit that is reliable and long lasting, is there anybody that has a turbo setup out there that can help me with the information i need. i would like a setup without opening the engine, is it possible, how about exhaust, is the stock OK, do i need a intercooler. my main use will be like 95% of everybody, ride around, go to work, and never let down a road race!. Is it something that you need a professional to do.

Thanks

Well its up to you, but if you turbo you should definately get an intercooler. And a free flowing exhaust for what your tying to do the stock exhaust is just going to be too restrictive. I understand that you want a type of support from the manufacturer but you should also be ready to not have any such support depending on what modifications you do to your car. I would say if your looking for somthing that is 100% complete or right around that, then call up stillen and tell them what you want and they will tell you exactly what you need to get that. You could also go to other companies but sometimes they are not helpful. Stillen has consistently been the most helpful company that I have ever delt with. There are going to be things that you have to have done by professionals, things such as tuning. I hope this answers at least some of your questions.
