I was wondering if someone could give me the lowdown on this thing. Does this manifold replace the plenum only? I have never seen a pic of any runners with it so I’m guessing thats what it does. For $500USD thats kind of weak.
No one has any info on this manifold…??
Currently ordering it!!’
Youll just have to wait!!
It replaces the plenum and runners. Engine response is much improved with this mod.
is that from personal knowledge? or reading it somewhere?
i havent ever used it, or heard of people using it, but i have read a few articles that say it doesnt really increase power, and the air ratios between intakes arent perfect…
but it is more high flowing. i think a port job on the stock plenum would do about the same as getting the greddy.
Shorter runners and larger plenum will help increase response. My buddy has one on his SR which I’ve driven. We have compartible upgrades on the motors.
It’s not a worthwhile mod if you don’t have the essentials to run higher boost and starting to max out on your current setup. This will mainly benefit the engine if it has breathing problems where the TB is causing a restriction from a set of big cams.
IMO, a custom sheetmetal mani with velocity stacks is a better route to go with. That’s if you have the resources to build one yourself, or pay big bucks to get one made.
ITB setup would be nice, but just too overkill!
I don’t know about improving response. I think it’s more of a mid to high end gain. I build intake manifolds over at Magnus in Woodbridge mostly for DSM and EVO VIII. They are a great mod for the buck. Usually dyno around 30 to 40HP for $600-700 depending on the setup it’s running with. It’s hard to buy that kind of power for that cheap. But something tells me the GReddy unit is not going to flow as nice as something a litle more custom.
I don’t have my Silvia yet…but soon. I’m deffinately gonna make one for myself. Here’s a link to some pics of the Magnus Manifolds…keep in mind we currently DO NOT make anything for SR20 so make sure if someone reads this thread don’t call assuming the pic is for a Silvia.
I’m not 100% familiar with the stock Sr20 intake mani, but I would doubt you’d see 30-40 hp with the Greddy unit. Take into account I’m only familiar with Honda mani’s and stock Honda mani’s are pretty good so you don’t experience much gain from an aftermarket one.
Best would be to search on zilvia.net or an equivalent site to see if anyone has dynoed one.
Ahh i say forget the GReddy. I’d rather build my own…a little easier on the wallet and a little more bling than the GReddy for sure. It would be nice to put one on after the other to see the difference in gains.
HAHAHA…
I was just surfing for info on manifolds and i found a link to this hunk of junk!! Check this thing out. They are selling it for over $1000USD and it’s built on a hacked up stock intake manifold. The realy sad part is I’m guessing someone has already bought this thing.
Actually it doesn’t really look like that bad of a piece. Kinda pricey though for half a stock IM
If you guys would pay more than 100bucks for a cobbled together piece like that, you need help.
Stay tuned, the good stuff is coming this spring. You will be notified when and where. SR20 and KA24de manifolds and more. Caker is right to laugh at that intake. Not just because it’s bad or ugly, but because its way too expensive.
Anyone with a basic origami class under their belt could get that going.

the larger plenum and shorter intakes are geared to higher CFM turbos and higher rpm. in particular ( and someone who builds headers SHOULD know this…) with vavles thier is a specific pulse length, this lenght or period changes as the rengine rpm increases and the valves are opening and closing faster… this puls will actualy change the direcetion of flow in the intake chanber momentarily with a pressure wave.the longer the intake manifold the longer the pulse it’s able to compensate for ( slower rpm longer pulse ), however the higher rpm’s ( shorter pulses ) get trapped in the long intake runner and tend to stall air … the short intake runner is ’ tunned’ to shorter intake pulses ( higher rpm ). So if you plan on incresing your RPM running your boost up high then yes a shorter intake manifold is worth it for power… just remember you will loos some low end power becuse of it… I would think the greddy unit is tested for tune at a specific RPM range. this would be the reason to get it or the replica off ebay that’s cast from an greddy… a custom made intake manifold is great but the person better have access to tunning charts on the engine or you won’t have a clue what your getting…
:lol:
You really love the sound of your own voice man…
you ask for an answer and then heckle the guy who gives it to you?
unbelivable…
locked up tight because your ungrateful.
