I found an s300 for a good price but i just need to know what sort of downpipe i will need and if are s300 turbos are the same? Are there different housing sizes and will it fit on my exhaust manifold? I'm not sure if there are a whole bunch of s300 variants and i need to be careful which one or what size i get?

What questions do i need to ask the seller about the turbo?

Thanks guys.

 

It depends on where the turbo is from, if its for a truck application it may fit, but off of a John Deere it won't, if thats what you were thinking. They come in all different sizes as far as A/R and flanges go, even the center sections can be different, or at least have different size bearings in them. Look for a BD Super B turbo, others won't last as long with the smaller bearings, ask for a part number, then call or email HTT, Piers, or BD and see what they have to say about it.

 

Yep its got a john deer symbol on it so its no good i guess
