Any if at all?

its upside down, and the bolt patterns are different. i think the throttle plates are bigger too on the fd

I knew they were upside down. The butterflies look a little larger, not by much to me. I cant tell about the bolt pattern. Almost like its more square.



Thanks for the info man

The FD's are 50 X 50 & 45

what about the TPS output?

the 20b TB is where its at https://www.nopistons.com/forums/pub...IR#>/boink.gif

How big are the butterflies?

It's not a gay plunger style TPS like the FCs.. Theres a resistor that bolts on to the main throttle shaft on the backside, and as the throttle opens, it turns the inside of the TPS..



And Mike it's not upside down compared to the N/A FCs.. https://www.nopistons.com/forums/pub...DIR#>/wink.png

FC is 45mm x 3.

FD is 45mm + 50mm x 2.

FD does not have any fittings for prior to throttle plates.

electrically they (s5, cosmo and fd) are the same. physically the cosmo and fd are not plunger style
