**RawBrokerage ISIS RB25 Manifold Review** - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

leesredgt · 02-14-2009, 09:27 PM

I had been looking for a decent quality and cheap Greddy style manifold for a while and was getting ready to buy an EBay when Ricky at RawBrokerage saw that I needed one. All I can say now is im very glad that I did not go with the manifold off EBay.

When I opened the box and pulled out the manifold I noticed the unusually smooth casting for a knock off manifold. There are some ruff places but nothing that wont be covered up buy the fuel rail or other parts. The main area is very smooth and top notch.

Top of Manifold:

Underneath Manifold:

Long shot of the intake:

Close up of the casting quality:

The flange that mounts to the engine was in the same condition as the rest and so were the intake ports, smooth as the rest of the Intake.
Intake ports:

When it came time to install the parts needed on the underside the parts went on easy. The water tube was a little tuff to install but I eventually got it with a little persuasion. The nipples and and hardware are provided with this manifold as well.

So the next part was to install the Manifold to the block. The manifold was very easily installed and took only a couple of taps to push all the way onto the studs. Once mounted the manifold sat flush and was easily bolted up with the bolts and washers provided.

The manifold comes with the tubing and clamps and zip ties needed for the cooling as well.
Over all I was very pleased with this manifold, for the price you just cant beat it. You get a good quality casted part with the service and backing of RawBrokerage, the backing alone of RawBrokerage makes it more worthwhile buying this part instead of one off of EBay.

So on a scale from 1-5….
Casting-4.0
Ease of install-4.5
Hardware-5.0
Price-5.0

So in closeing,if your looking for a cheap, good quality, non EBay manifold, look no further because RawBrokerage has got the part you need.

I have one as well, however from a different company, same thing.

I agree with everything you have said. I went over some of the ports with a fine file to get rid of some of the small burrs just to be safe. But 20 minutes of filing is no big deal to me at all. I used my own nipples so I had to re-tap some of the holes to be a little deeper. I honestly think that the price for these vs. what you get is very good. I have seen some of the ebay ones just looking like absolute garbage...mine looks WAY better than those.

I have a question for you man. Mine came like yours without the big waterhose neck not put into the manifold...what did you do when you put yours in? I'm guessing some kind of sealant and just pounded it in?

leesredgt · 02-14-2009, 11:31 PM

Well im kinda wondering if i should have put some kind of sealant around mine.I just took it and kinda twisted it while pushing in on it and it went in pretty easy.Like i said i didnt put not sealant on it so will see.Im not totally for sure what kind of sealant i would need to be honest.

Cool review, no driving impressions? I've never driven a stock RB25, but I've driven one with a Greddy IM/cams/GT3071, and loved the powerband.

leesredgt · 02-15-2009, 12:03 AM

Thanks! To be honest with you,i haven't got the engine back in the car yet lol.Im putting the engine into a convertible.

Ive got a build thread in Chat if you wanna check it out.

Yeah just saw that and was like "oh, those pics look familiar" lol.

Good stuff!

Fairly noticeable throttle response increase, but however I don't see a noticeable gain in power at all. I mainly did mine so I could use less specific strut bars, less intercooler piping and overall cleaner look. Money well spent for me.

ANVIL · 02-16-2009, 10:40 AM

i have one of these waiting to go on also, looks really good. i also had to file some of the ports but it actually wasnt a big deal. im wondering if anyone has one and can compare it side to side with a greddy unit. mine looks really good and i dont think you would be able to tell it from a greddy. only thing is theres no install instructions and i have to search forums for install just to be sure. wouldnt be a big deal, just sucks for me because my laptop at home is being serviced and i dont know when im getting it back.

i wish i would be able to tell you if just the manifold how the power changed from the stocker but im also doing my injector and turbo upgrade at the same time followed by a retune.
