RB20 Plenumn's?

[Nismo_Boy]

I'm after an aftermarket plenumn for my Rb20det. I've had a search and came up with nothing. Seems like either a custom made one, or a "cut n` shut" style job on my stock iteam.

Does any one know of any bolt on ones (like the GReddy ones for rb25)?

Cheers, Josh.

Rips make a custom front facing plenum for whatever engine you have. Keeps all factory sensors unlike the Sub Zero, or Greddy plenum.

His email is [email protected] and his name is Rob. The pic shows the Rb20det version. You get it in a kit form, in the colour of your choice for $1500NZ (Roughly $1350 AUD) Comes with modified throttle body, throttle cable, water pipe kit, all fittings for brake booster, map sensor, boost guage etc....

Great buy in my mind.....thats why im getting one

Josh, i'll PM you the email address of a workshop who has an awesome rb20 plenum that weld onto your stock bottom runners. Excellent design and only costs $600 or so. Definately my choice once i get the $$.

sorry to bump this thread, but i'm trying to get hold of an aftermarket plenum and being from the uk its basicly imposible to get one off the shelf :wack:

can you get Greddy plenums for the RB20DET??

If not anyone running one of these RIPS ones?

Thanx, superclarkey

greddy rb20 and the 25 are the same im 99% sure

The RB20 plenum has offset runners for 5 & 6 to clear the master cylinder in R32's.

So i don't see how a RB25 plenum would fit, as it doesnt have any offset runners.

[superclarkey]

Well the engine is not in the standard car, its in a 180sx so i hope it should fit

Just need ti find one

I want to live in oz, you are RB20DET gods

[thizzle]

lemme find this aritcle i got...its a 32 gtst with rb20 with exact same plenum i have on my rb25...

edit::blah its 25 i stand corrected :Oops:

[superclarkey]

Thanx for looking anyways mate

See the offset runners on the RB20.

Preety dodge for Nissan to do that on a production car i reckon.

[superclarkey]

I don't know what to do now, your saying if i make a RB26 one fit that it would not be good for the engine.

So what do i do, buy a RB26DETT? as i'm going to be needing alot of bits from that engine so i may as well just buy one?

GTR plenums don't work on the RB20DET.

The factory plenum gives not only more low down torque, but better top end as well.

Nissan got that part correct.

There was an articles in Zoom magazine a number of months back, where they couldnt figure out why the RB20 went like a dog, as it turns out they removed the modified RB26 plenum put on the the factory RB20 plenum and power and torque went up everywhere in the rpm band.

I could scan the article if you want.

But yeah, get a whole RB26DETT if you want to go down that route.

greddy rb20 and the 25 are the same im 99% sure

Good thing you werent 100% sure as they dont fit:(

Greddy only make manifolds for the RB25 adn RB26, neither of which fit the RB20. Workshop X in NZ also do nice looking plenums....whether any work better then the std one i dont know

[superclarkey]

this is the thing guys, i don't want to spend all this money on a RB20DET if for the same kind of money it would cost to tune a RB20DET i could get a whole RB26DETT and basicly run the thing near standard

I'm still looking into it, and if you do have the time to scan that, that would be good

[superclarkey]

One of my mates has a plenum made somewere in oz, i think it was sub zero or something?
