When I look on ebay for a neon turbo I see most of the stuff says for a eclipse too could I buy a wrecked eclipse and change everything I need to turbo charge my car in my neon? Like turbo, manifold, injectors etc.

its the same motor as the eclipse but i think they're are some minor differences but not sure

Yes the 16g turbo used on the Eclipse will fit the Neon to. You may need a different manifold. But it willl work and quick spool.

Would the intercooler and everything fit it that I would need? I know the injectors would

it wont bolt right up, but you can make it work with a little modification. or you can look for the srt4 parts. they will work better because they literally bolt right up. plus the turbo will make as much power but spool significantly quicker. and whats more, the IC and everything else should be cake to install - and is much more efficient than an eclipse IC

OMFG the eclipse does not even come with a 16g that is an upgrade its a GT25 and NO the motors are not any thing alike you are thinking of the gs-rs eclipse with the 420a NOT THE 4G63 do not try 2 make work you would need a manifold with a mitsu flang
