Fd Housings Ond Fc Engine ?
#1
hey there, i looked into some engine stuff here, and i saw that the fd inlet and outlet ports are significantly bigger than the ones from the fc, so, is it possible to like just swap them , for the sake of more performance. this would be for a NA.
sorry if this is a newbish Q, i am just curios i Guess
Thanks in advance

The inlets really aren't flowing much if anymore air than the fc housings. The FD lower intake has the air entering at a 45 degree angle while the FC is at 90 degrees. It makes it look much bigger though and if you were going to build a custom intake manifold, it might even be worth it. I chose against it, but I did use all of the FD internals and FD housings in my rebuild. The FD stationary gears are hardened and the bearings are multi windowed like the competition models. That and the FD rotors give a slight bump in compression compared to my S4 stuff.
This is all with regards to a turbo motor. As a NA, you wouldn't want to use the turbo rotors and will have to get an aftermarket intake manifold anyways.

Check the photo out. Ports are the same on the inside of the motor. The ports from the LIM to motor are different.
left plate is a S5 ported, middle plate is a stock FD, right plate is a stock S5. Not worth the hassle ( to me ) changing to FD plates. Motor mounts, LIM, fuel system, intercooler pipe.
