SR throttlebody?

[Dattebayo]

Due to how strange the KA TB looks on my mani, I was wondering if a stock redtop SR20DET TB will work on the CA mani any easier. I am assuming that the KA and SR have the same size TB (maybe from memory). Is it more workable or should I stick with the KA?

not sure about the red top but the black top SR has either the same size or slightly smaller TB than the RWD CA.

argh. I was sure it was a 60mm tb... it makes sense given the qualities of the motor.

, yup, measured one up quickly the other week, the sr one was slightly smaller.

Thanks, dodged a bullet there!

And I appreciate your help...

Not quite.. The SR20s have a 60mm on the MANIFOLD side.. The IN side of the tb is the 65mm.... It's like saying " I've got a 5" exhaust" when I've got a 2" exhaust with a 5" tip
