I started getting into Forced Induction when I decided to attempt restoration of a 1985 Nissan 300zx. However due to the issues in the body and frame of the car, it has become a junker.

My new goal is to finally invest my time into a 2003 350z I have. However, I pulled the turbos off of the 1985 300zx and a 1986 300zx parts car. From all the lurker research I've done, they'd do well on this in a twin turbo application. My biggest hurdle is that I already have equal length long tubes on the car and am trying to do what I can to save them.

 

Welcome! The trouble with equal length long tube headers is that they're often not readily usable unless you want a rear mount turbo, and if you have room in the engine compartment, it's better to put the turbos under the hood. I'd recommend selling the headers you have and buying a set of turbo specific manifolds.

 

I have noticed this and think I still have a decent set of shorties here somewhere. I noticed rear mounts seem to have a bad reputation. I also can't find pre made turbo manifolds for the 350z outside a turbo kit either.

 

Some turbo kit companies may sell the manifolds a la carte if you contact them directly.
