will an intake manifold from a 280zx turbo directly bolt onto a non-turboed 280zx and all the factory sensors and injectors fit? If so does it help any? I know the throttle body is a 60mm oppsed to the stok 50mm.

 

Do you have a turbo throttle body? How do you know they are 60mm? I never measured mine but from looking at it I thought it was the same size as the non-turbo. I've also never heard of any changes in the airflow for the turbo engines' intake manifold. I would say to just do a mild port job on the non-turbo manifold.

 

Every time I've seen a turbo TB on ebay it says 60mm, and thats over the period of two years, so I don't think everyone who has sold one has lied the same lie. so therefore I believe there is a small difference, but I,and ebay sellers, could still be wrong. Maybe the first person put that to sell better, and everyone else was too lazy to measure it and used his size, I don't know, it's America, anythings possible.

 

That 60mm isn't off of the Turbo motor. That's the 240SXx TB conversion. It's advertised as FOR the turbo, though it's just the same that you can do it to the NA. From what I understand the turbo and NA's both came with the same dia. TB. If the Turbo had come with a 60mm TB, than why would anyone want to "upgrade" to a TB thats the same diameter as the one they already have?
There are also 60mm aftermarket versions of the L28 TB like what MSA.

 

I went out and compared them and measured them. They are the same.

 

They factory throttle bodies are the same for the turbo and non-turbo.

The 60mm TB's are from the 240sx and are a common upgrade on these cars.

 

If I were you, I would just put the 60mm throttle body on the NA intake, if it fits directly to it.

 

i dont think it dose cause onebay there is one and it says u have to have a 1 inch spacer
