I have a huge exhaust leak that just won't go away. and I've had it for some time and I've replace the gaskets
so I think it's safe to assume my t2 exhaust manifold is leaking... (has a crack) My buddy offered me his s5 manifold.what all would I have to do to swap them... I thought it was just one vacum hose differnce but I'm not sure... I need help badly.. any info would help... thanks.

 

To use that manifold, you need the S5 turbo as well, including oil and water lines.

 

What if I fabricated the s4 turbo to fit the manifold... what then? would everything work out?

 

No. You could find a S5 turbine housing and put it on the S4 turbo to save cash. That way you'd be able to use the S5 manifold, as it is completely different from a S4 one.

 

the flanges are differnt bolt patterns the the s5 is rectangular and the s4 is slanted on one side

 

Just look for an S5 turbo for sale. You can prolly get one for like $200.

 

i know a guy selling not sure if its sold or not yet Fox4Life is his name he wants like 200 for it

 

So if I get an s5 turbo... It'll be plug and play to my manifold and my waer and oil lines?

 

Would you guys all recommend me stay s4? WOuld that just be better?

 

ya the coolant and oil lines are the same

 

No, the S5 has a far superior wastegate, twice the size of the S4, and the S5 has no twin scroll stuff to remove. I did the swap and I would highly recommend it to anyone.
