I dont have acess to my motor right now, but i am trying to order couplers to go from my 2.5 inch intercooler piping to the stock throttle body and stock turbo outlet? What are the diameter of both, in inches please ( in other words i need to go from 2.5 to what for the throttle body, and 2.5 to what to the turbo? thanks

Here are the throttle body sizes...
S13 SR20DET - 60mm
S14/5 SR20DET - 50mm
S14/5 SR20DE - 60mm
KA24DE - 60mm

60mm is about 2.25"

You're misleading this guy in to buying the wrong coupling.

60mm = 2.37" which is the ID of the TB. When you buy coupling and intercooler pipes, you buy stuff based off of OD. Take a tape measure and go measure it.

well that's why I said that it is about 2.25". The Silicon couplings will stretch a li bit to fit the od of 2.37"...

very true, i think i will just have to wait to take the tape measure around the turbo outlet, cause i am not really certain about its size, but thanks guys, i was just trying to get ahead of schedule.

You still missed it. 2.37" isn't the od it's the id converted to inches. A 2.75" coupler fits ka and s13 sr throttle bodies.
