All FC Throttle bodies are the same are they not? I am gonna go grab one off the series 5 NA and see if it's the same as my GTX one....it should be right?

The N/A and Turbo TB's are different.

How so?

there are some differences due to the tb being filpped over on t2 vs na.



the coolant flows through the tb on the t2, on the na it does not. the double throttle is actuated by the secondary throttle on the t2, on the na it is not. the na has the idle air bleed screw on the top, this isnt present on the t2 as it would be on the bottom (unusable).



there are probably some other things i havent noticed, i've only looked at the t2 tb briefly but those are the differences i remember noticing.

also the castings for s4 and s5 are slightly different, although very close

Peng? rebuttle?....hehe

rebuttle? I don't think j9 was disagreeing with me https://www.nopistons.com/forums/pub...IR#>/smile.png



I havent seen enough tb's to know the differences between s4/s5, but if j9 says they vary, I believe it.
