RS SOHC and WRX Intake manifold differences

Odyknuck · 01-30-2009, 08:57 AM

What are the differences between the top feed Intake manifolds in regards to Injector spacing, diameters etc. Specifically will the After Market WRX fuel rails fit the RS Manifold using WRX Injectors

+1 for info on this - interested to see if other rails can be modifed to work with the sohc phase 2 intake manifold

Ok, Can some one with a WRX measure the Center to center distance of the Injectors.

Looks like approximately 5 inches from center of back injector on pass side to center of front injector on same side. I'm guessing it would be the same for the driver side

the injectors on the WRX TGVs measure 4.449" apart. That's 113mm.

ody - what measurements did you get for the stock RS setup?

Brydon · 02-03-2009, 01:04 AM

They are the same size center to center. The manifolds bolt up the same The ports are located at the same spot and the injectors sit in the center. There will be no difference. however the rest of the manifold and sensors are very different.

Thanks for posting a more exact number. It was hard enough getting a decent ruler under there, lol
