I think it's going to be easier to do a DIY turbocharger installation than a DIY supercharger installation. Less custom fabrication to do. You won't gain as much in the low-end as a SC but you'll have less parasitic loss. Superchargers actually eat up quite a lot of your power to actually spin themselves.

 

Lets see your explanations on the cost difference.

 

Not gonna give you one. Do it yourself if you want it.

 

Turbo would cost way more and take a lot of fabbing lol

 

realistically, how big of a turbo would you even be able to run on the 2.8? I think I read someplace that neither of the PES superchargers push more than like 8 or 10 psi (depending on the tune) because the 2.8 can't handle much more than that

 

Uhh, no it wouldn't. You don't even need a turbo-specific manifold unless you're looking for absolute maximum performance. You can mount it a bit further back easily. It'll have a bit more lag, but it'll be way cheaper and easier than a supercharger. You'd probably want a GT30 or so. It wouldn't be IDEAL but it would still be a good improvement.

Or you could go for twins like maybe GT22s but we're not looking for expensive, so...

 

I would think the turbo build would cost more to.

 

Which is why almost nobody does a custom supercharger setup, right? Oh wait...

 

Why couldn't the 2.8 handle any more boost than 8-10psi? I would think with the larger displacement it could.

 

Depends on how strong the internals/seals are and what the compression is, etc.. I don't know, but if they didn't make the engine with boost in mind then it might not take a lot without rebuilding it in a boost-friendly way.
