Andrewtler Posted January 13, 2011 Share Posted January 13, 2011 I have been looking at a siemans Deka 850cc top feed injector upgrade on eBay. It comes with fuel rail etc. And it says it suits a rb25det neo engine. I am wondering will this suit my series 2 r33 gtst engine? And will it work with the plazmaman front facing plenum which I have already ordered? Cheers Andrew Link to comment https://www.sau.com.au/forums/topic/350202-injector-compatibility/ Share on other sites More sharing options...

Just having a stab at the plenum - the deciders on whether your plenum will match up I think are the throttle body diameter and also the size, orientation of the plenum. I don't know what this plenum looks like but I do know you will need to make sure the throttle body matches up...

It's a 95 gtst with a series 2 engine which has the ignitor built into the coilpacks but I don't think series 2 is the same as neo. I'm pretty sure the neo is from r34s. Also i got a 76mm plenum to suit Link to comment https://www.sau.com.au/forums/topic/350202-injector-compatibility/#findComment-5623302 Share on other sites More sharing options...
Andrewtler Posted January 13, 2011 Author Share Posted January 13, 2011 Has anyone experienced Bosch 750cc injectors inan r33 gtst? Did it idle rough? Was it ok with a aftermarket fuel pressure regulator?

Shouldn't be an issue as long as you have the fuel pressure reg. The rating of injectors refers to the maximum fuel they can flow. 750cc injectors should flow enough fuel for most setups.

I've heard plenums generally will require a bit of work to get them to fit, especially from eBay. I can't really comment much more as I haven't fitted a plenum myself. Good to see you've got the matching plenum outlet. Link to comment https://www.sau.com.au/forums/topic/350202-injector-compatibility/#findComment-5623588 Share on other sites More sharing options...
