Anyone know of a respectable Nissan 240 tuner shop in or near Philadelphia that can do work on the internals of the KA24DE?

 

I don't know of any specific tuner shop that only deals with Nissans... but I do have a friend that has had a shop build the internals of his engine, now I don't know what it cost him, but I do know that he's got 450hp. It's called DARE automotive I believe... and it's in the west chester area. I've heard they do great work on other cars as well, but I think the main thing of the game is to find somebody that you trust doing the work. So if i'm in your position I'd just keep my eyes open and if you find a place look around a bit, and ask about any projects they might have worked on.
