Greddy Copy Plenum ***pics***

[zertek]

Ok guys,

I have a Greddy front feed plenum copy that i purchased from ebay. Anyway ive had some time this week to finally start assembling it and ive been documenting it for a tutorial im making.

Anyway, the finish on this product is very average and i decided to check with you guys on one part about it that im very skeptical about...

You can see one of the water gallery holes on the greddy plenum is poorly cut and is dangerously close to the cylinder 6 intake feed. Total gap between the 2 feeds is about 2mm. I DO NOT want to be filling my cylinders with water, ive already experienced this once and it hurts!

Do you think when applying the silicone i can just give a bit extra to that part? Im a bit worried to attempt this as the risk is pretty big...

ADVISE PLEASE GUYS!?!?

if it was me i wouldnt use it

it looks rough inside obviously

the standard one would be better.

your a brave man tobe putting that on your car! try contacting the ebay seller send them pixs and ask for an exchange for a better one!! i really wouldnt put that on your car! your only asking for trouble! your trying to save $500 by buying a knock off greddy peice but will cost u a 3k motor in the long run! heres a saying in the automotive feild you should live by-"if u cut enough corners, you will just end up in a circle"

Let this be another lesson.

If its cheap, its cheap for a reason.

yea but the problem now is i was stupid enough to paint the plenum and cant really arrange a refund now when it cost me over $350. Im thinking now maybe i can get it custom welded to join to the standard intake manifold runners???

Anyone here capable of doing this?

[nick81xd]

what you could do is take it to a welder and get them to put some more metal to make it bigger distance between the two then get it refaced for sealing.

wouldnt cost much at all and you still would be cheaper then a over priced Greedy plenum from a store.

[zertek]

yea that would also work... cutting it further back on all 6 runners and welding the standard runners on would make for some very clean holes though as all the feed holes on the copy plenum are pretty ruff...

[zertek]

Just thinking about it i shouldnt have to pay for extra welding or modifying when i have just been sold shit! So i have contacted the seller on ebay.

"Dear seller,

The plenum i recieved is not in working order as one of the water galary feeds is cut very poorly only leaving it with a 2mm gap from the air intake feed... This doesnt allow me to fit a gasket and isnt really repairable with out some expense from a welder. I would like to organise an exchange for another one that is in working order.

Thank you,

Regards, Michael"

Im not good with being all legal or what ever but i hope he can arange something and sort this out.

Dude, you paid $350 for something correctly made, would cost $1000+

I dont see why your complaining.

You tried to skimp on the costs, and got done.

Its a "copy" so, the comment back will most likely be "it was a copy, doesnt have to be exact" or similar.

mate i know its a copy but having previous experience with a JUN copy front feed on my old RB20det i was extremely happy with it. the feeds were identicle to the stock feeds and the over all finish of the product was smooth and precise. Keeping in mind that this was ALSO a copy for around the same price.

Going by my previous great experience with a copy, and weighing up my options on price of coarse i selected another copy. this time being a greddy copy for an rb25det.

Dont try and treat me like a idiot.

[zertek]

also when they state " to fit RB25det" when IT DOESNT FIT means, if its a copy or not, they claim it fits

Im not treating you like an idiot.

Im simply telling you that if you expected something decent for $350, your kidding yourself, and now that you did get done... its time to just get over it.

Performance isnt cheap, its as simple as that. If you try and cut corners you'll end up paying for it in other ways.

Now you have to spend coin to get the thing to a useable if you want to use it, or you just eat the cost and learn from it

he has 16000+ post u need to respect his knowledge on these cars and 50$ welding id still be happy but this is why i dont like internet buying,i like to see what im buying with my own eyes

[dangerman4]

the question is

why didnt you inspect the manifold upon receiving it in the post?

the first thing you should have done is inspect it for transit damage, and or faulty manufacture.

then you could have sent it straight back.

im with nismoid on this one, you got screwed, but the only person to blame is yourself for not looking

properly to begin with.

get it welded up and then reshape it with a die grinder and move on.

when i got my tig welder aust post told me i was not allowed to open it i had to sign clearance first

then i got chokes for my webbers(private) and it was same

and just recently a roll cage from bond for my new project and wasnt allowed to unpack it there and then

and on closer inspection those ports are real ruff so id complain too i guess

[zertek]

Also at G1 last sunday i was speaking to a couple of drifters that had them installed and they were very happy with the results. I guess i got a dud.

Also yea i am an idiot for not dumby fitting it first. I really stuffed up there and ignored my own advise (always dumby fit).

oh well atleast now there is a warning to the many people on the forums, that i have read are curious about these plenums.

I personally wouldnt every buy another one unless i could inspect it with my own eyes.

Get the suspect ports fill welded and ground back shouldn't cost too much, I'd say it would still be usable once this is done. I wouldn't be asking for an exchange, I'd be asking for credit as it's not worth the $350+. $150 your way would be fair.

Can you still access the plenum advertisement in your eBay feedback? if so take careful note of how it's written, some ads on eBay can be deceiving to the actual description of the item.

yes i have accessed that and read over it. They cover pretty much everything except they dont state 'DET' after RB25. although i quoted them on that before purchace and they assured me its for RB25det.

The people i have spoken to with these installed all have good results... i was the unlucky one and recieved a dud

I will take your advise and question them about a credit. hopefuly something to help cover the costs of the welding.

sorry but you get what you pay for unfortunately,a lesson i learnt 13 years ago.
