Hey, are there any differences between the S4 na block and S4 turbo block. Can you just switch out the manifolds and electronics. The car I am buying has an Na engine in it now but the manifold for the turbo is still on there just blocked off and the electronics are still in there. I think he swapped in an 88 na engine and just put the old turbo manifolds on, also some of the electronics are still around just not connected.

 

Turbos are 4 port, na's are 6 port.

 

am i missing something here?

 

maybe someone dropped in an old 4 port 13b na motor ?

 

sorry didnt fully explain I have yet to confirm the 6th ports but the engine is from a 88 gxl I think so I assume it has 6 ports. I guess its kinda hard to explain maybe ill take some picks once i get the car in. In the case that it does have 6 ports that pretty much solves my questions, totally forgot about that .

 

In order for the stock turbo manifold to clear the N/A intake manifold, you will either need to get a set of Tii manifolds, and port match the LIM to the N/A LIM gasket.



OR



Put a spacer on the stock turbo manifold.



OR



Just buy an FD manifold, drill out the bolt holes a bit. (aftermarket turbo/wastegate reqd)

 

stupid computer

 

So the Fd manifold would be easier to fit on, other than using a spacer on the T2 manifold

 

Wait, the guy u got it from swapped a n/a engine into a TII, and the manifolds and everything just bolted on? how the hell does that work, and where are the 5th and 6th ports exhausting to?

the aux ports are only on the intake...



so where do they take in air?
