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

Do you have a neo engine? If you do, it should, providing they aren't lying to you.

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...

I don't think I have a neo engine. 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

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.

Yeah I don't think you have a Neo. Someone correct me if I'm wrong but I think the very last of the S2 33s came with the NEO and these would have been built in 1998.

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.

      Hahahahah, look, your not wrong 😂😂 and thank you brother 🙏🏼 jokes aside, I haven't driven the car in 6+ years and it's like I'm starting all over again, and furthermore the car is wayyyy more powerful and it's characteristics are night and day different now compared to what I remember. So I'm slowly easing myself back into the groove, the car is literally scaring me a bit tbh.....it feels like it has 200hp more than it does on paper and responds like a cammed Ls v8, and-some! 😅 every single bit of throttle pedal travel and input has instant response all the way to the floor, zero flat spots or labouring feelings, it's nuts. Im shooketh, go easy on me hahahaha or don't 🤙🏼😊

      If the house has ever been sold before too, they have photos from that etc.

      I used to do that, but then I got savvy. The benefits of having your phone photos geotagged outweigh the negatives. I just don't publish any photo straight off the phone/out of the gallery/off google photos, etc. If I'm going to use a photo, other than for SMSing to fam, I will always open it on the computer, copy it/otherwise edit it and save down without the original metadata, before using it. For example, posting photos of my engine bay into a thread on here, to show someone a plug or something - I will just screen-cap the section I want to use and paste that section direct from the clipboard into the post. No metadata goes along with.
