Greddy Intake Manifold vs Knock off intake manifold

[asiandude15]

I was curious if anyone has ever compared a knockoff Greddy Intake Manifold compared to an Authentic Greddy? Someone told me they are exactly the same except for the Greddy Sticker. The same material and all as far as I've read on the internet, cast aluminum.... Do they perform the same? I would rather spend like 200 rather than 500 on an authentic if they are the same other than the sticker.

i know on the oil pan the casting was a big difference i had to break a piece off. it looked like it could have broken in the pan. on the intake man just get the cheap one and get it ported

[sr20det drift]

yea i would also like to know the difference on them

[burnsauto]

its just not as clean a casting. and i've HEARD a RUMOR about boost seeping through the pours of the casting...but i dunno if it was ever proved.

the quality control sucks so some people have no problems and some people have those issues you stated

[codyace]

Casting wise, they are most definetly not the same. Threaded holes for Throttle body and other areas also were questionable at best. I'd be leery of pieces breaking off under boost (little casting pieces...it looks like 'stucco' inside).....

Bottom line is that it may work, but the Quality Control is not there...

Real Trojan condoms or knock off Trojan condoms?

Hmmmmm?

Wonder which everyone would use?

i need to remember that next time anyone wants to buy a knockoff "performance" part.:loco:

[asiandude15]

People always start to hate and make jokes when a thread like this comes up. It is nothing to do with buying a knockoff performance parts, its like buying a TV. You shop around for the best deal. The tv's pretty much look the same for the most part (i.e the sizes of the screen, depending what size you want to get), just they have different features and some perform better than others. So you run by Sony and an Emerson with the exact same specs down to a "T". But the Sony is priced at like 2x the Emerson. Which do you choose? I have heard Sony products in the past have a had a reputation for repairs like their laptops, I have friends that work at electronics stores. Alot of people tell me they have used emerson for years with no problems. I'm just simply trying to find out the best bang for my buck. That is all.

[Z33dori]

my friend ran knock off Greddy and it works fine for him.....

this car goes through hell and we havn't had a problem with it......


i've never heard of anyone else having a problem with the knock greddy manifold.....


so fucking buy it

Neither. Heh heh

[slider2828]

Here are the problems I have heard. The cast for the intake studs don't line up so might nee to file. The flange needs sometimes to be checked for flatness, that is where the boost seep happens. Usually the problems are with the flange but I don't think anyone has cracked one open and check out the inards yet.

[wayneside]

i have one from topspeed pro 1 performance and it works fine...

The difference is, if your TV goes bad, it won't take the DVD player, VCR and Tivo with it because it coughed chunks of metal into the other pieces.

[eek]

There are other differences besides brand and size for tvs. Using tvs as an example is a poor choice. JFYI Sony uses Samsung panels for all of their LCD TVs. Even their top of the line XBR Bravia series use Samsung panels but they use a different PROCESSOR which is the one of the major differences between all the brands out ther besides the panel. There are a ton of things that come in to play when choosing a TV. Most LCD panels are made by Sharp. And I'd take a Samsung LCD panel over a Sharp panel anyday of the week.

Anyhow, you get what you payfor. Spend 200 bux on a fake, and have it cause problems down the road, or spend a lil extra and get a authentic part that has been proven time and time again. Something that goes on/in your motor I personally would not skimp. Why risk causing damage to your motor that cost anywhere from $2000-3500 from trying to save a lil cash. Not to mention the time you need to waste if a problem does occur.

This is always a hard subject to discuss. the condom and TV examples don't really address this question in my opinion. when comparing name brand stuff to "no name" brand stuff, especially when it comes to performance parts, you really need to have experience with inspecting build quality and know what needs to be there to have a quality part and determine whether is should or shouldn't be used.

For example: I purchased a set of CS pulleys for my SR for $70 bucks. The single reason I did not buy GReddy pulleys is because I had the opportunity to inspect a set. The GReddy pulleys are nice but there is virtually no difference ,other than maybe the anodized finish quality; and only time will tell who's is better with that, than the CS set. I spend all day creating machined parts and issuing them to be built; so when inspecting machine finishes, alloy hardnesses, manufacturing processes, and other aspects involved in creating a quality part its obvious to me where corners where cut. Those are things to consider when comparing a "known name" part to a "no name" part.

Now for a manifold....since this is a cast part it means that someone has DESIGNED and issued a mold for creating the part. It also means that time has been invested for research and testing before someone deemed it financially feasible to produce and sell for a profit. This is what I believe GReddy would have done before the part hit the market. In the case of a knock off and or a possible exact copy, there are many things to consider. A casting is used to get you closer to what you actually want to produce. In the case of a manifold the designer knew that this part will have to be machined afterwards for a correct fit and probably accounted for that in his design (i.e. adding additional material to be removed). When a "copy" is created from a part like that, there is no way for that new person to have known what was there and why "X" amount was removed, because obviously he didn't do it. The next thing to consider is if this new knock off creator knows much about machining finishes and what surface quality will best suit a gasket. I could spend all day going through problems with copying cast parts but it should start to become obvious. Also don't forget that all this can be checked IF A. you know what to look for and B. you have something creditable to compare it to.

Buy it for cheap and spend the money to insure a quality part....

Buy it install it and cross your fingers....

Or buy a quality part for a reputable person and sleep easy...

its your car so you pick.

[corriganjoshua]

I agree just go with the greddy and sleep easy

"Knockoff = Knocked up"? ;)

[jhec23]

A lot of people will swear by genuine products because they are widely used and tested by a lot of people. If you buy and use knock offs and it breaks on you then everybody that you will ask for help will give you just one answer 'because it's a knock off and you have to expect for the worst'. If you are using expensive good brand and something goes wrong then definitely a lot of people will try to help you fix and figure out what went wrong because they know the product. Sometimes the extra money we pay for good brand will pay for itself in the long run.

[Z33dori]

you could also just buy the Intake manifold from PSM.......its like 200 bucks u gotta wait for it to be shippped over tho.

[idahotuner]

PSM?.....

i went Greddy that was my only option. i am not going to risk my whole build. over a cheeper part.

Ok well I am a big buyer of name brand parts. I just personally think alot of name brand parts are over priced and I always like to find alternatives, but I am also aware of quality. I just wanted to see what people thought and know about the manifold. I'm not trying to start an arguement or anything. I was just using the forum to find out information like it is supped to be used. I know people who have experiemented with "knock off parts" on their cars just too see how they perform. I met a guy who told me he once used a e bay turbo kit on his honda for like a year and boosted it to the max every day, he never had any problems except when he finally blew his engine when he turned up the boost. The same guy also used a full greddy kit on his other car and he said the two cars made about the same power except the 14-15percent gain the GSR motor made because of VTEC (he had the same compression pistons in both cars). He told me things are not always what they seem and he was very surprised. But then there is also those "E bay intercoolers" which I know a ton of people are using! I haven't heard of anyone having any problems with them. Thanks for the comments guys or girls. And thanks "s14unimog" for that well written explanation. I'm gonna buy the "knock off" and Ill see what happens, I know a guy who owns a greddy and he asked me to go voer so we can compare them, he is pretty curious as well. As far as knock off parts go, everyone who makes good products has to start somewhere, I don't think Greddy made a name for itself overnight. And I was aware of the sony screens. Also did you guys know alot of phones here in the US are just rebranded phones that other companies made like the AT&T tilt. The phoen in the UK and Asia is branded with the "O2 XDA" label... But neither of them make the phones I think, a company in Taiwan does, I'm pretty sure... I'm pretty sure there are car parts out there that are made exactly like name brand parts but just branded with some third party brand. For all we know, maybe this manfold is a Greddy reject because of the minor flaws. LOL Who knows, this thread has been fun

[eulalia]

all i want to add to this thread is that if anything goes wrong with the actual greddy one you have someone to call, and get help to fix the problem (not always the case, but for the most part)

i dont know, they might send you a new one or items to fix the problem

and on ebay, the seller does not have to really back up his product

great example of this is when stance coilovers had that problem with the ball joints, they helped everyone out with the problem, and got the problem resolved for the most part

i doubt this generally happens with items you buy on ebay

just my two cents

[driftage240]

ive had both....its really a hit or miss w/the fakes...ive played w/shit long enough that u get what u pay for..

[GabeS14]

he SAID HE BOUGHT THE REAL ONE>> SO this thread is done...
enough!:duh:

[whereda40at]

Someone told me they are exactly the same except for the Greddy Sticker. The same material and all as far as I've read on the internet, cast aluminum.... Do they perform the same? I would rather spend like 200 rather than 500 on an authentic if they are the same other than the sticker.

the sticker can be put on if you want to.

[steve shadows]

The last car we tuned has a ton of vaccum leaks due to improper fitment of injectors into the slots on the IM etc as well as leak because the flanges between the IACV and the manifold itself were warped from PRODUCTION.

This was not a Greddy Style IM though it was one of those surge tank style one.

If I were you I would get the greddy or a real JUN or JDM version of the surge tanks style.

Just note that your power band will be late with the JUN style surge tank/IM.

And guys thanks for all the help....

And yes with name brand products, you do get the support in case anything goes wrong... Good point...
