quick gt2871r turbo fin observations - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

bl3ujay07 · 08-29-2009, 01:28 PM

Ok, i plan on buy a gt2871r from some guy and asked him to send me some pics. First, i thought it was the 28rs disco potato but he said it was a 2871r. Plus, i checked the number and it shows up as a 2871r on the garrett site (unless someone can double check just in case im looking at the wrong place).

Question is, it looks like one or two of the fins are chipped a little (picture attached). It looks like little nicks, but is it still good/worth it for $600, maybe TRY and low ball him $550 or $575? (Not gonna say location bc someone else might pick it up

).

Got my flame suit on for those who would like to flame me today!!!

KoukiMonsta · 08-29-2009, 04:39 PM

thought the 2871r had a flange mount for the intake pipe......

lazysk8er2 · 08-29-2009, 04:49 PM

^ they have different ones.

personally i would check the shaft play. cant really tell if any seals are blown thats a risk you have to take. but think about it you could just be losing 600 bucks or luck out and get ass good deal.

obviously its been beat on and raced even if they say no. as for the chips that wont really matter. the seals and the bearings is what you should be worried about.

bl3ujay07 · 08-29-2009, 05:32 PM

like koukimonsta, i thought the gt2871r came with the flange mount so i assumed it was the disco potato one. I check the number on the turbo and it said the 2871r. hm...im debating either try this one or just find a s14 or s15 t28 but i want 300+ hp without worrying about maxing out the turbo.

Sileighty_85 · 08-29-2009, 06:14 PM

they also make the 2871R in that style

GSXRJJordan · 08-29-2009, 06:30 PM

Correct, you can get different intake styles in the 2871R.

Yes, it looks like the blades are chipped. If that's the case, it's going to create an IMMENSE amount of heat around those chips, and the turbo will destroy itself over the course of a few thousand miles - it could just be the pic though. I've had people say that's just paint or something, I don't know if I buy it. Have the owner take some new pics.

For $600, there's almost certainly something wrong with it. Shaft play?

bl3ujay07 · 08-29-2009, 06:37 PM

^^^Sileighty_85, any difference between the two or is it just preferences on the flange part?

If you want the OEM intake pipe to work, you need the flange type. Most people like the 3" because their MAF or intake pipe is 3" anyway.

I think it looks much more gangster

but some (especially in other car communities) are interested in OEM fitment/look.

*fliprayzin240sx* · 08-29-2009, 06:41 PM

Its all just preference...some folks have S14/S15 setups and the that will bolt on to everything you have.

bl3ujay07 · 08-29-2009, 06:44 PM

GSXRJJoradan, he did say that they are chips on the fins and said that he "bought it like that". If you say it will destroy itself then its a no go for me. He also said there is no shaft play, but i have yet to drive there and check it out for myself.

JacksonBrown · 08-29-2009, 06:48 PM

Here's a couple of pics of my 2871 .64 -- unassembled as I just got the exhaust housing back from JetHot and the rest of it back from having a new center cartridge put in. My 2 cents: never buy a turbo w/ any chips on the exhaust wheels unless you're planning on having the whole center cartridge replaced. Chips = big time inefficiency. You can have the whole cartridge replaced for ~$400 so if you can scoop up that turbo for ~$500 then you've got yourself a decent deal. If you pay more than that, you may as well buy a new one...

Another good reference

Def · 08-29-2009, 08:25 PM

That's not bad. Those chips won't really affect much at all. Maybe 1% max on compressor efficiency, which you would never be able to measure/see while it's on the car.

I'd rock it for $600 and never think twice about it.

bl3ujay07 · 08-30-2009, 04:26 AM

so will IT or will it NOT effect it that much. You sure 1% effiency?

anton1o · 08-30-2009, 05:38 AM

Ive seen turbo's with alot more damage to fins still rock it for a very long time, Turbo was probarbly ran without a pod filter, You wont notice a thing, its not like you will get a massive amount of air turbulance with that minimal affect to the fins.

Id pay $550.

where did you get a new cartridge replace for ~$400?

Seriously? No I'm not sure, NO ONE could possibly sure on that with some poorly lit picture.

My point is it won't affect anything, and you'd never know those chips were there once you install it.

bl3ujay07 · 08-30-2009, 12:42 PM

Can i get more input from GSXRJJordan and Def??? One state its nothing and the other, it'll blow itself up with all the heat and turblance it causes. More factual info from both sides. would greatly appreciate it.

EDIT: HOPEFULLY better pics of turbine

KoukiMonsta · 08-30-2009, 01:17 PM

thanks for the info

*!Zar!* · 08-30-2009, 01:20 PM

Looks good to me.

Run it.

Sileighty_85 · 08-30-2009, 01:24 PM

Why dont you Email Garrett about it with the pics

They will give you a more definate answer seeing that thet are the ones that build them.

+1 now thats a good idea

GSXRJJordan · 08-30-2009, 02:49 PM

Chips don't look too bad... they will definitely make it less efficient, but I'd run it for $600 if there's no shaft play.

bl3ujay07 · 08-30-2009, 03:32 PM

Thanks, i am going to check it out on the weekend. Check for shaft play and see the chips in person. Will update.

*If i end up buying, will be seeing steve for my tune!!!

From my Garrett dealer, who, from my understanding is one of the largest in the U.S.

When I scooped my 2871 up from my friend, I pulled it apart and had it sent out to my dealer for inspection. He advised me that all of the blades on the exhaust side were chipped. Apparently, something went through my friend's motor and chipped all of the exhaust blades. My dealer stated that it could have been as little as half of a pencil eraser and given the size of the chips the turbo was probably 50% inefficient. My friend was running a cheap Chinese manifold at the time, so it's possible that a booger weld could have broken off and found its way into the exhaust side of the turbo, causing the chipping. Having discovered that the turbo wasn't in the pristine condition that my friend thought it was, I asked my dealer what should be done. He advised me that, at this point in the game, Garrett dealers are now supplied with complete cartridge replacements, rather than the various pieces that compose the cartridge. This keeps it simple for the dealer and end user and comes at the price of ~$400. The turnaround is 1-2 days tops.

Moral of this tale: be careful of the quality of manifold that you run. If it's low quality, it may have "booger welds" inside of the runners that can potentially break off and go through the exhaust side of the turbo, chipping the shit outta the wheel. ANY chip on the wheel affects efficiency -- it HAS to. By design, no turbo is 100% efficient to begin with and chipped blades only increase inefficiency. To what end/point do you deem that the condition of the blades is worthy of replacing the cartridge is your call. Just don't get it twisted and believe that chipped blades don't increase the turbo's already inefficient design.

ryan hagen · 08-30-2009, 09:33 PM

ok, thats the exhaust side, but he has chips on the intake, mine is worse than that and it lasted a whole summer of being beat on. they sell garret compressor wheels on ebay for arround $60. i plan on getting one at some point for mine

JacksonBrown · 08-31-2009, 09:41 AM

Lol. You can have that perspective and that's cool.

Chipped blades won't stop your turbo from working, so there's no logic to your statement.

Chipped blades on both the intake and exhaust wheel = increased inefficiency.

That's cool that they sell wheels on ebay, but the question to me was about getting the cartridge replaced, not whether or not procuring wheel elsewhere was an option. I'm sure your comment does add some useful info to this topic however, if a person was looking for a source wherein to procure just the wheel.

Ghost240 · 08-31-2009, 09:49 AM

Ummm those wheels on ebay arent as good as the garrett one's and will most likely disintegrate at speed. So I suggest actually going to a shop when it comes to rebuilds and not going by what people say in forums. ESPECIALLY when it comes to BB turbos.

I know 240 people are cheap and like a good deal, but remember you get what you pay for.

P.S- At those speeds its alot more than 1% inefficiency.

Nismo240z · 08-31-2009, 10:16 AM

that turbine looks fine man, they're very small I'd rock it

ryan hagen · 08-31-2009, 11:27 AM

UM they are suposed to be garrett wheels, so i dont know what you are talking about

s14unimog · 08-31-2009, 12:58 PM

My concern would be with rotational balance. These blades are turning incredibly fast, so an imbalance will have adverse affects on the bearing tolerances. Forget everything anyone's said on here and contact Garrett. Don't guess, get a correct answer.
