Hey guys, Ive done a bit of searching through different forums including this one and cant really find any info on these plenums. They appear to be good quality, have velocity stacks inside the chamber and are nowhere as cheap as greddy copies!

Just wondering if anyone has used one of these on their rb25, wat the quality is like, performance, etc. Currently deciding whether or not to buy a genuine greddy plenum or one of these as i can purchase with a 90mm throttle body for 1g. Thanks for any input you can provide!

this was covered on the greddy copy thread they are not as good as they look id go ahead with the greddy for that tiny bit extra i have a greddy copy and it is good but i suggest you not go for one of these

they dont look anywhere near as bad as the greddy style ones, ive been contemplating..

if u look at the rb20 ones u will see its the plenum with standard runners welded on, suppose u have to remember the postage is another $175 on top.

pretty sure those JUN copies are made in Thailand or Taiwan... cant remember...

Greenline sell the genuine Greddy ones for $885 so just go with that. Atleast its a proven Japanese brand and you will be supporting the company who has ACTUALLY come up with the design and done the research and development...

I concure....looks better than the greddy knock off.

But then again..they could show you a Jun one and give you one of theirs..... >_<

I had one of these jun copies installed on my rb20det. It looked to me like the standard runners had been welded on... it was a very good plenum and even used velocity stacks.

but for a couple of hundred or so extra, would be good to go a genuine greddy...

There's another jun copy thats a larger version.

I've seen the larger rb20det jun copy plenum. Its quality was actually pretty damn good. Velocity stacks inside, welding was clean; no noticable seat of the pants loss of down low but a hell of a lot more up top.

It wasn't a 'bolt on' and required a few mods to get it all working.

Also.. $700 is a bit rich. They can be had for $400ish.

yeah, look at JET200 (ignition DVD project car) it had a millenium motorsports custom plenum on it, replaced it with a GREDDY one and bang .... more power everywhere low, mid and top..... there is a lot more to plenums than just a pretty weld job....

I received my plenum (with 80mm throttle body) about a week ago, it definitely looks the part, and the workmanship is top-notch.

I'm fitting it to the car in two weeks time, so I will let you know how it goes.

    • Sounds good.  I don't 100% understand what your getting at here. When you say, "I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down" do you mean this - there is a panel with factory paint, without any prep work, they paint the entire panel with primer, then colour then clear?  If that's what you mean, sure it will "stick" for a year, 2 years, maybe 3 years? Who knows. But at some stage it will flake off and when it does it's going to come off in huge chunks and look horrific.  Of course read your technical data sheet for your paint, but generally speaking, you can apply primer to a scuffed/prepped clear coat. Generally speaking, I wouldn't do this. I would scuff/prep the clear and then lay colour then clear. Adding the primer to these steps just adds cost and time. It will stick to the clear coat provided it has been appropriately scuffed/prepped first.  When you say, "but the new paint is landing on the old clearcoat" I am imagining someone not masking up the car and just letting overspray go wherever it wants. Surely this isn't what you mean?  So I'll assume the following scenario - there is a small scratch. The person manages to somehow fill the scratch and now has a perfectly flat surface. They then spray colour and clear over this small masked off section of the car. Is this what you mean? If this is the case, yes the new paint will eventually flake off in X number of years time.  The easy solution is to scuff/prep all of the paint that hasn't been masked off in the repair area then lay the paint.  So you want to prep the surface, lay primer, then lay filler, then lay primer, then colour, then clear?  Life seems so much simpler if you prep, fill, primer, colour then clear.  There are very few reasons to go to bare metal. Chasing rust is a good example of why you'd go to bare metal.  A simple dent, there is no way in hell I'm going to bare metal for that repair. I've got enough on my plate without creating extra work for myself lol. 
    • Hi, Got the membership renewal email but haven't acted yet.  I need to change my address first. So if somebody can email me so I can change it that would be good.    
    • Bit of a similar question, apprently with epoxy primer you can just sand the panel to 240 grit then apply it and put body filler on top. So does that basically mean you almost never have to go to bare metal for simple dents?
    • Good to hear. Hopefully you're happy enough not to notice when driving and just enjoy yourself.
    • I mean, most of us just love cars. Doesnt necessarily have to be a skyline.
