I would like to figure out rather the follow parts are interchangeable:

- can a power steering pump that came off a S5 N/A put on a S5 TII engine?
- are the sunroof assembly the same between S4 and S5? (replacing the pair of brackets that the panel bolts on to)
- will a S5 N/A tranny bolt onto a S5 TII engine? dose it require any mods?
- will S5 bumpers just bolt up to S4 chassis?

thanks.

 

Yes.

 

It will bolt on, but you will need to run the S5 N/A Flywheel, N/A clutch, N/A Clutch Slave Cylinder, and possibly a custom drive shaft to whatever you are running in the rear.

Don't expect it to last long unless you treat it really well.

 

Starter is different too.

 

sunroof assemblies are interchangeable.

 

Guess I'll get the only question left:

P/S pumps will be interchangeable.

 

thanks alot everyone

 

Right! Good catch. When I put a TII setup on my car the wiring was short, so I had to extend the starter wiring.
