Default Unsure if I should keep 2560 or go to a 2871

In my search to replace my 2560 I keep finding 2860R and RS's as well as 2871's. I've been reading up on the bigger turbos and it keeps bugging me that I think I should go that route.

It would be on my stock vvt motor with 3" and no cat and a begi log manifold and SGDP.

I do highway 5 days a week and some rare in town driving. Most roads are quite open here.
I don't want lots of lag but do want a nice ceiling and like everyone and their dog says I hope to go to a built engine one day.

I'd love to eventually have a 300whp car. But maybe 280 is fine, thus the dilemma, will I be fine with a 2560 for the next long while?

Has anyone regretted say going from a 2560 to a 2871?

I guess I haven't made up my mind. Who can write poetry and describe the driving experience so well it's like I'm on a test drive? No steamy harlequin stuff "as he shifted into 3rd my loins became alive with excitement......."

Genuine - actually mine is doing what yours was some time ago, we talked about it on the thread where you mentioned your failing CHRA.

Chinese parts - as if, I only run genuine items, like an unknown IC and coilovers made under strict tolerances from the Land of Race........

No regrets here. Maybe it sounds stupid, but I actually prefer the spool characteristics of the 2871 to the 2560. It annoyed me that anytime I tried to accelerate the least little bit I'd be at 10psi and subsequently boving like a 17 year old kid in an srt4.

http://www.turbobygarrett.com/turbob...R_743347_4.htm

Here are the specs of a 2871 I was looking at:

Comp.
Ind Exd Trim A/R
53.1mm 71.0mm 56 0.60

Turbine
Wh Dia Trim A/R
53.9mm 76 0.64

I'm still learning my trim and inducer numbers and how they influence spool so I need help here. The -4 is one of the larger 2871's as far as I can tell. Looks like there are 8 part numnbers for 2871's !!

My option is replace the 2560 and sell it once I go over 12 psi with a built engine and at that time go bigger on the turbo. I may lose a bit of money on the future larger turbo swap but not much, but perhaps I'd be happier now as I'm staying in safe boost levels for the stock motor and I may not be utilizing what a 2871 was really intended for.

Although I don't have the genuine Garrett 2871 and have the chinacharger that BEGi sells. I do like the spool characterstics too of the 2871. It could be annoying short shifting at 4k rpm and be close to max boost. Spool comes hard after 5k rpm and I like it.

I didn't say cheap, but I definately wont be paying retail if I can help it. Cheapest new CHRA for a 2560 is $495, entire new turbo is $720 and at those prices you are close to a very lighly used 2860/71

I like tubular manifolds with the bigger turbos but for what you want a GT2860rs is a prime candidate too, speaking from experience. I've had a few different turbo cars with a few different turbos and the 2860rs with a tubular manifold is sweet.

Is this a common failure for the 2560? I'm trying to source one now...but for my HP goals a disco potatoe is sort of over-kill, although for track duty running lower outlet temps with lower boost could be beneficial

I was all ready to buy one (2860RS Ext. WG and BEGI tubular) with deposit in place but it didn't work out. The manifold could not be repaired by BEGI. I was getting pretty excited and now I feel bad for user pschmidt as he is stuck with a mani and DP combo that has no other use. He was great to deal with and over the last few weeks I have been salivating about a larger turbo and the accompanying tubular manifold. When I got the bad news from him about the unrepairable mani I was still stuck on the larger turbo's.

I'd say it's very very rare for a ball bearing Garrett to fail unless it's not getting oil and water but I've only been following turbo's for a year and a bit.

Mine still boosts but it boosts so slow you can hit a 3rd gear corner (on the streets) full throttle and by the time your halfway down the straight your at 12 psi......ha

No, it's not rare. It's COMMON. There have been a whole bunch of Garrett failiures here even from people posting in this thread. Look around at other car forums and ebay and you will find a shitton of blown garrett BB CHRAs. Garrett ball bearing turbos SUCK. Why the **** would you buy another one. Get a different brand.

I appreciate hearing from the other side of the Garrett fence. What do you like and why compared to Garrett?

BTW -Telling someone something sucks without providing some learning or further information is not very useful, but I'm sure you were just about to elaborate.
My issue is that used Garretts are out there for a decent price, but if I can find something with great value in another brand I would consider it.

Here.

Blown Garretts.


I bought a Borg Warner. Better because rebuilding doesn't cost $500. It costs $100.

^^^^ What Min said, people need to get off the Garrett high horse and see what other cars are running with great success. Precisions, Borgwarners both ring a bell...
