I was given a s4 turbo 2 upper and lower intake manifold today with throttle body, TPS, the works. I was wondering if I could put it on my s5 n/a with little to no modifications. I'm planning on putting a turbo on it (obviously) I have access to any other parts I need. Other than the upper and lower intake manifolds and a turbo manifold, what do I need? Should I buy T2 or n/a gaskets for the intake manifold?

 

Get the NA gasket, you will have to port the LIM to fit a 6 port engine, be very careful with it. The S4 TPS will not work with your ECU.

To just hook up the turbo to the car you will need the manifold and oil and water lines. Then you need support systems etc. New MAP sensor, FMIC, Fuel, etc etc.

 

Okay, use my s5 n/a TPS. Should I get an s4 MAP sensor or s5? Is there even a difference? I'm thinking about running 550cc injectors on it. Can I do so with the stock pump or time for a Walbro?

 

Definately a walbro and some 550CC injectors, you'll need to get a S5 TII ecu. The harness will work that is in there though. Make sure you have brand new filters etc.

youll need a fmic and bov too, this is the bare minimum. You will break drivetrain parts if you turn up the boost too much as well since you have na parts.

 

Damn, i was hoping to get around switching to T2 ECU. Oh well, it is plug and play with my n/a harness, that's good. I'm in the process of replacing filters and such. I'm running way lean right now and detonating. Got a new fuel filter and going to check the timing tonight.
