im looking to get a new turbo, i see tons for sale and wanted to know if i need a certain turbo or can i just toss any on there, plz no flames im new to turbos

 

Basically any turbo will work on any engine, but that doesn’t mean any turbo will work well. A turbo should be selected to provide the right airflow for the power you want at a boost level close to that turbos peak efficiency.
The biggest problem is mounting it. Anything other than the stock turbo will require a new exhaust manifold unless the flanges are similar enough that an adaptor plate can be made.
If you only want a mild upgrade, consider upgrading just the compressor wheel and housing. You can then flow more air at similar boost, meaning your not over-speeding the turbo, which will kill the stock bearings. You’ll need to port the wastegate, or better yet do this to a Series 5 turbo.
If you want to get serious though, you’ll need to replace the whole thing, manifold included.
