This is what the one from APC looks like.

The difference is that this looks like it is meant to be there and it is apparently identical to the GREDDY manifold but takes the standard injectors (not standard throttle body).

That APC one is looks no different to a Greddy Plenum!

I'd say it is a greddy plenum!

call them

http://www.apc-racing.com/

this one is cheaper (around $700) than the greddy (around $1100) and i am told that the greddy wont take the standard injectors because of where the fuel feed is where this one will.

All i want to know is if someone has used one of them, if they have had any problems and if they have had good results.

hi guys could you help me out i'm stuck over here in the uk freezing my arse off i've been following this thread with interest as we don't have anyone in the uk that does manifolds could someone post links up to the manufactures website cheers guys

yeah i run the plazmaman plenum on my rb25. It seems to work well, with very very quick throttle response and no lag.

I don't think i have quite that power that the other one on the dyno has..

But i've only got cooler', pod, and cat-back.

That looks exactly the same as the GREDDY as you said, can anyone confirm that it is THE SAME plenum without the name logo and the expensive price tag?

[R33NT]

I have seen it, it isnt a GREDDY and it is not that expensive but i want to know performance.

I was told by APC several customer cars ran this plenum. I guess they could be VL's but i was hoping for a couple SAU members.

Greddy

"APC COPY"

The APC one may be a copy of the greddy one but i can't see any diferences between the two of them.

there must be a slight difference if the greddy one doesnt allow you to use the std fuel rail, and the APC one does?

[Roy]

Are you sire you cant use a std fuel rail with the Greddy? I know of one that uses a std GTR rail, adn he is only using that so he can use the injectors, so if the GTR rail fits the std manifold and the Greddy, then i say the Greddy would have no problem with the std RB25DET fuel rail

Bont Blitz make an apaptor these days so the RB25 can run a complete RB26 inlet and throttle bodies...much better option in my eyes considering the price that the std GTR goes for

Yeah they do, but it costs about the same (1000+) as the greddy manifold

The GREDDY rb25 plenum still uses the standard fuel rail. Fitted on mine with no problems.

ahh, cool. Dunno where i got that from then.

These APC ones look pretty good for the price. If i wanted more than 300rwkw, then id consider to buy one

excellent I was getting worried for a bit then

[SKY 34]

heys I was told that Greddy only produce plenum for RB25 R33....do you think it'll fit into R34s?

[R31Nismoid]

Do a search, R34 Plenum issues has been covered a truck load

agreed

[sky30]

Do the APC or GREDDY plenums fit the R32 RB25 n/a head??

[PHaT MR30]

std injectors and rail fits these plenums

<{POST_SNAPBACK}>

Which is what i said back here about std rail and injectors... we ran a std RB25DET rail on a mates car with GReddy plenum and i am running top feed RB26 injectors on mine, it just depends on which injector seat you use (there is a step down in the plenum to suit each injector)
