Ok i have been having a lot of problems with turbos latly.first turbo was good for about 6 months.got car tunned with the turbo and was going fine till about 3 months later.the nut on the shaft on cold side came off and caused all blades to break in the housing.why dident exhaust side break?so i ordered another turbo same one so i dont have tune again and about 3 miles the blades broke again on cold side.thought it was my fault cause i dident put a cover on cold side inlet.so bought 3rd turbo put screen cover over inlet and 1 day later blades are broken again.all 3 turbos broke on the inlet side of turbo nothing wrong with exhaust side.anybody know whats going on cause i have no idea.any help is greatly appreciated.

Ok that info "helps" alot. What brand? Model? Sounds like a ebay turbo

EmminoDaGreat

are you getting oil to the turbo?

turboaccord77

yes it is a ebay turbo by godspeed company.its a t3/t4 63 trim ar70.i searched around for info on this turbo people thought they were ok as long as you use a oil restrictor.the turbo is getting oil.just not understanding how the blades break with a cover on it.2nd turbo has 2 miles on it and 3rd turbo about 10 miles.

Ever think your getting a knock off? You get what you pay for. Try buying a turbo at a shop n see if you still have the same problem. Or just get a turbo from jdm from japan my friend got one for 500 the brand name was jdm he saw it in a honda tunning magazine installed to a b20

JDM is not a brand, JDM stands for Japanese Domestic Market...

And OP, I would agree though that you get what you pay for. I've seen quite a few threads where shitty turbos break off fins (or worse.) There is a thread in the S2000 section looking at an eBay turbo kit.

You are far better off purchasing a brand name turbo (Garrett, Turbonetics, etc) as opposed to the ones you are buying.

the cost of three of those turbos has to have added up to more than a Garrett or Turbonetics

so everybody thinks its just the turbo,even though between the two last turbos there is only 13 miles on them.also nobody know what can cause the blades to break in such a short time?just shitty turbo?thanx for help guys

I'm not sure if you're being sarcastic or what, but from the sounds of it there isn't really a whole lot else that could be the problem. If you're buying shitty turbos and all of them are failing at the same part I would think that tells you there is an inherent weakness at that part.

turboaccord77

hey bro not being sarcastic at all,just trying get to bottom of this situation.just want to be sure its the turbo and that i do not need to look anywhere else for problems.with that being said going to look for a garrett or percission turbo.thanx again for the help

Well it's a well known fact that eBay turbos are often out of balance, etc. But for you to break 3 turbos in the exact same way is puzzling. Maybe if they were all out of the same batch of turbos, but I seriously doubt that considering the time difference between the first and second one. There's a good amount of variables here that could be affecting this. I'm not gonna jump on the "durrrrrrrr eBay sux get on my level n0000b" bandwagon because that's not going to help anything. Check your feed/return lines and make sure they're good. You also didn't specify what generation accord you had. Do you still have your front motor mount?

jdmcertified909

Im sorry did you read my screen name? I know what it is. The brand is jdm im looking at the magazine right now. Jdm sport turbo with the jdm logo on it. And by the way the magazine is called project honda

AztecEGhatch

What type of manifold are you running? Me thinks you have a log style manifold that gets pretty hot and and causes the metal to expand or bend.. Why does it happen on the cold side? maybe the makers of the turbo felt since its called the cold side it doesnt get hot enough to need as high quality material as the hot side

Apparently brand is JDM Sport:

http://www.jdmsport.com/about.htm

So we're both incorrect assuming that's them. And your screen-name means nothing to me, the number of 12 year olds that have picked up the term 'jdm' is ridiculous. I would most certainly wager 30% of the users in Appearance/Cosmetic believe it just means 'awesome'.

Nice generalization , his Accord generation is listed right under his username as a 1993 Accord.

Let's take a look at that thread I referenced to earlier.

jdmcertified909

Lol funny. Im 21 went to wyotech. And im sorry that you didnt get what i meant. Yes it is jdmsports. I know where it came from. Like i wrote my friend bought it from a shop in gardena ca. After seeing it online on jdmsports. Im the one who told him about it when i seen it in project honda magazine

turboaccord77

its a custom made equal length tube mani.so not a cheap mani.lol.have no clue why it keeps breaking on cold side.hot side still good.

turboaccord77

all oil lines are fine and could not use front motor mount.i did buy poly mounts that are in the car.

turboaccord77

Guess i'm gonna look into a garrett or percission turbo now.also pull motor check everything out,do a little more building and hope for the best.lol.thanxs to all you guys that helped.anything else that comes to mind post up for me.thanxs again guys

Problem solved. Whether it was too much heat, low quality internals, or being out of balance, the problem is that you are using poor quality turbos. There is a reason why turbos are so expensive. A good house costs a lot of money like a good turbo, but you can still get a house for 1/8th the price using cardboard instead of drywall and particle board for the frame.. looks like a house (turbo) and does all the stuff a house does (turbo functions) but doesnt last.. (you go through 3 turbos in like 12 miles)

AztecEGhatch

I guess my point was more that the cold side is breaking because of the heat around the turbo but the exhaust side could be fine because the exhaust side is stronger than the cold side

keep in mind you can get a used garrett/precision etc. and rebuild it for a lot less $ than a new one

turboaccord77

lmao,i got what you saying.the first turbo did last for 7 months.12 miles between last 2.gotta find a good turbo.
