Injector Sizing - Gtr

[VSPECII33R]

I bought a set of ID2000's for my GTR, but seem to be having a bit of a drama with fitting them... The inner diameter (side that slots into manifold) seems too large at 13mm to actually fit. What size are they meant to be?

Am i missing some type of adaptor that reduces the 13mm injector body to something like an 11mm tip to slot into manifold, or have i been supplied the wrong injectors??

You need an adapter from 14mm on the injector Oring, to 10.5mm on the rail. There are a few suppliers around, but I know 'injectorsonline' can help you.

Sorry, i'm speaking about the opposite end of the injector that sits in the manifold. Fuel rail side is sorted with a 14mm rail.

[scotty nm35]

Oh, sorry. The plenum side should be 14mm I thought.

[VSPECII33R]

Anyone that confirm the above 100%?

My plenum looks as though it may have some type of sleeve in the opening, but upon closer inspection (plenum still on car) it appeared that they were a part of the original casting... Not so sure now??

As far as I'm aware, the injector sits hard up against that port, and is held their by the pressure of bolting down the rail.

The Id2ks don't go inside that port like a factory or jap brand injector.

Correct me if I'm wrong

[VSPECII33R]

The O-ring doesn't make contact with the manifold as the tip of the injector is too wide to even fit in a few mm, so i didn't think it was right. Pressure would just hold the plastic end cap down to that cast flat section, negating the need for an O-ring even, but would leak under pressure afaik??

Would love to hear from someone that has fitted a set of ID2000's to a standard plenum GTR!

Me too I havnt installed mine yet but plenty of ppl have hopefully someone knows

Just called CRD & they have told me they're meant to have an adaptor with them to suit RB26 application. Will be chasing up the seller for these as it was specified they were for my GTR.

Post a pic the adaptor when u get them mate

[VSPECII33R]

Will do champ.

How did u go with this ?

I would have thought many ppl would have installed these injectors and know the answer?
