No. Not really as it only the top half that has been change. Simply the volume.

The runners are exactly the same, only this is better as it can now get more flow due to the pure size and 80mm throttle body. And this was built by someone who knows the ins and outs.

Size doesn't mean better flow, by someone who knows do you mean someone with an engineering degree? Theres a lot of maths in designing runners and a plenum to suit.

id like to say to say its good to finally see someone put this to the tests and see actual results not "my auntys dogs cousins sister said that her friends sisters boyfreind tried this and it was crap or......it made 1 million kw on 2psi with this being the only upgrade" lol. will be following your results goodluck

lol :teehee: ^^

everyone seems to be against "test and trail" of these plenums

i say give it a go, i have one off these and im goin to post up pics

paul r33 you say "its such an integral part, it would be like using fake chinese injectors

do you really want to risk it ?" yet paul is goin to modify a ecu the main brains of any rb and noone is against him..

i say keep up yet the test of the plenum lets see results and if it brakes and blows the motor than we knwo not to use them ...

At this stage im going to have to say I think im out of testing at the moment as i cannot locate a flow bench for starters, plus with cams on the way and isl33ps' plenum looking so tempting for something that has been tested flow benched and is much closer even between cyls and flows a fair amount of air for the right price, I dont know if i can resist in not accepting that, so at this stage i have to say "its a nay" How bout you teazn did you end up testing it???

i have not tested it but i have finished it very strong very smooth f**k the test ill compair it to my last dyno run willi have a flow bench here but mine is on the car cbf taking it off where you located ? can get it done if you want

I have a Greddy Copy eBay special.

Checked out the inside and it all looks very simetrical, only rough bit was ONE of the ports (but anyone who is holding the manifold in their hands and doesnt port match it should be shot).

Exterior was rough (but the original greddy's arent too smooth either) but nothing some time and patience couldnt fix. If your buying this for bling factor your a bloody idiot (i purchased it as im sick of having unnecesary pipework everywhere in my already limited space... RB25DET in a S13)

Fitted.... No leaks... works fine....

You dont always "get what you pay for", you also ALOT of the time pay for the brand name.

Some one flow test these thing DOOOO ITTTT!!!!

I'm really keen to see the results, i'm planning to use one on my rb when i turbo it, mainly for the piping route.

If this is just a direct mould of the real greddy item with some rough edges, with a bit of cleaning up theres no reason why it shouldnt be just as good as the "real thing". If the greddy manifold has such a good rep without the velocity stacks, then i cant see a reason why a copy with a bit of time spent on it cant flow just as evenly.

There is no point flow testing it, each one of these manifolds i have seen are different in one way or another, clean it up and it will be fine, internals were all good.

I'm rehashing this thread.

HOW/WHERE on earth do you plumb the AAC valve into ?

Yes, I know it bolts to the bottom of the plenum, but the black hose, that normally runs to the I/C pipe just before the throttle body - where does that go? Is everyone making up custom ones? Or just putting a breather on it?

Anyone have any REAL pics of the full plenum install?

you need to hook up a line to the IC piping before the TB so as to allow measured air into the system.

The Copy inlets do need to use the R33 AAC, but it's not as easy as just bolting it in.

RE Customs has done A JUN copy plenum suited to an R33 GTS-T and it works, but I'm not sure of the ins and outs of it.

Maybe you need to call Ray....

    • Oh and my rear arms may need some attention too.    
    • Bushings are almost done. Check the date stamp 馃槀 these are likely the original bushings with 27 years and 243ks on them.     Was too dark to get a pic of the worst one.
    • Porous blocks are a known issue on something like a Porsche M96, it's not really something I've ever heard of on an RB26. It's possible what people thought was a "porous block" was really a cracked block that they just didn't spot the crack on.
    • This is a controversial subject really, the whole power vs fun thing I mean And this is the main reason I got back into a MX5 Of the last few notable daily cars I've owned whilst I have frequented SAU R33 GTS-t: fun, but because I'm a idiot I modified well past a reliable fun car and ended up hating it, although that was my fault because I tried to have a daily cruiser and race car all in one, the family called it the sometimes car, because sometimes it was working, sometimes it was broken, gladly sold it NB MX5: brilliant car, thrashed the Bejebus out of it, but, again, was stupid and deleted the air con, power steering and stripped the interior out, whilst still fun, and reliable, and super cheap on consumables, it was not a fun place to be going on long cruises, I did love it, but basically every family member hated going anywhere in it, sadly sold it 2015 WRX STI: soulless thing that looked like your average Kia sedan and had that horrible boxer engine with glass ringlands, the family did like it though, that thing was one of my stupidest purchases and I still regret it 2017 Toyota 86: 馃槳 if I didn't crash it, I would probably still have it, it was a fun little thing, even with that horrible boxer engine, the family did like it, the only reason I didn't get another 86, or, BRZ was the boxer engine, I should have learnt after owning the STI, but I'm a idiot VX SS: great cruiser, fits the whole family, and was fast as.....in a straight line, but a big fat thing, so no enjoyment throwing it around corners, the family was unimpressed with the whole boganness of if, but they did admit it was a comfy place to sit on long cruises As for the NC, I feel it is perfect for what I want, or need out of of a car, whether I'm cruising the Hwy, back roads, twisties or peak hour traffic, the Mrs doesn't mind driving it either, or cruising in it as well, although she does bump her head of the roof nearly every time she gets in, which is farking hilarious, and the kids love taking it for a thrash as well So basically, I've had constantly more fun, and way less headache and heartache, both on the track and on the street, in low powered cars,  go figure.....LOL One thing though, the Mrs has stated that the cams have made the exhaust sound much louder, which they have, but it doesn't bother me, in fact, I actually like it, but, to negate any future comments from the Minister for War and Finances I may look at some changes to the rear muffler set-up to drop the volume down a tad to appease her when we are out and about in it
    • You will need to extend the turbo inlet pipe somehow, which could/might be done with silicone/rubber pipe, but might need steelwork, depending on your intake. And you will need to change the pipework on the outlet in teh same way, but this is more likely to need steelwork.
