2.5" inlet?
From memory the box that i quickly knocked together for my engine:
is about 4L, and a 3" inlet.
I reckon there are gains to be had from going larger from what I have now.
the original GTiR back plates have a bit of a step in there to raise the volume a bit which we don't have. However that said 2.3L is decent.
If the distance from the trumpet/radius to the inside of the box is one diameter or more then that's a good guide, which in this case is 48mm. Also an air box size atleast bigger than engine diaplacement which in this case is 1.5x.

Shelldrake's 4agze/20v hybrid TA22 made 236rwkw on 19psi with a plenum that had about the same (if not less) volume as the GTIR intake. his plenum didn't have any radius into the throttles either, just a plain hole in a 3mm thick box. He is now going to one of these GTIR set ups to replace the existing one.
The 2.5" inlet is fine, since most people run 2 or 2.5" intercooler piping.
NA plenum volume is a different kettle of fish for sure. Bigger is better I say!
Yeah, pressurised plenums are a different kettle of fish to NA plenums.
But i would say that quite a few people would be running the GTIR stuff NA?
I guess it all depends on setups like turbo sizes, head work, cams and what u want the motor to do. I'm looking for response and torque so I think this would be fine for me.
I am going to have an update in the next day or two, also we have worked out a way to make this work with a blacktop

A pic of it installed on my car. it is a shitty photo but it does the job.
looks great, hows the clearence?
I will have the first 4 plates ready by the end of today. I will go back though my PM list in order to see who asked first for one.
I didn't expect to end up selling these when I started this thread, funny that. I do however want to keep things on topic so anyone has questions about sales send me a PM, for anything technical related or fitment post here.
As for the 2.5" vs 3" inlets, I upsized on my own intake and I did pick up a small power increase, it was very sublte and part of it could of been due to the larger size being better merged into the air box.

It comes pretty close to the clutch master, roughly a centimetre away maybe.
The stock bov location also gets close to the bonnet but most people will be cutting that off and filling it anyway.
I have a feeling that it might fowl when there is load on the motor but I cant test that at the moment cos my shit aint running.
did you have the heater flow control tap in there when you test fitted this one?
