Injector seals and O Rings?

[Got2BeBoosted]

hi, probably a stupid question but was just wondering where about's i can find R32 RB20det injector seals and O rings? anyone know good places to pick these up or order from??

Nissan. You just need a part # to take with u to make your visit easier.

[amnash]

would they be the same as the rb26?

[beacher1B0]

Not sure. Probably since rb26 injector fit in the rb20 rail and manifold.

hey Got2BeBoosted if u get a part number plz post it up

You should be able to email or call your local nissan dealership parts department and they should be able to look it up. or if somebody has that parts catalog program thing they can look it up.

thanks for the part number, i tried 240sx seals(read somewhere they worked) but they still leaked.
hopefully when my engines back together with these seals in place it will be dry as a bone

also, those numbers..are they for an individual seal/o-ring or is it a "seal kit" because there's 3 seals needed per injector..

[TheyKilledKenny]

Theres an insulator and o-ring that sit on the fuel rail side of the injector, and another insulator on the tail side of the injector.

16412F 16618-78A00 O-Ring
16603F 16635-78A00 Fuel rail side insulator
16603G 16636-V5000 Tail side insulator

I looked at gasket kits but there all in Japanese and I couldnt pasted the characters into a translator. Let us know how it goes.

[amnash]

wow sweet man, where you finding these numbers exactly? (if u mind sharing)
also you think the only thing that should be changed is the o-ring?..the others being named insulators i assume they don't actually seal anything? just for vibration?

[TheyKilledKenny]

I looked it up on Nissan FAST

I havent swapped out my injectors yet, Im planning on dropping some in deatschwerk's or maybe sard's when I upgrade my turbo, intercooler, and computer. I assume its just the one o-ring from what I have read on forums, they always say to replace the o-rings, never heard anything about the insulators.
