These 370Z's with appropriately sized turbos have very negligible lag and that large displacement gets that turbo spooling up quick. You really need to go for a ride in one.

Also, I'm not trying to push you into the stillen setup with my A2A kit but had to chime in on the statement that you dont have a shop that could install it. If thats the case then dont buy ANY turbo kit either since they are way more complicated to install. 80% of the guys buying the upgrade are doing it in their garages. So if you dont have faith in a shop that does that for a living then i wouldn't take my car to them for anything at all.
