Garrett or Chinacharger?
 

Is the almost 1000 dollars worth the extras? Main thing I can see is ball bearing instead of thrust bearing.

I've been on my Garrett for about 75-hours and 15k miles and never had a problem. It still has stock-like shaft play and I bet I'm harder on it than you'll ever be.

You should look at the Borg Warner stuff too. The new EFR stuff is looking pretty good.

T25 housings possible?

Pretty sure people here have confirmed that the chinachargers make less power.

If it is a street car I see no reason why to not go with a chinacharger. For a track car I would not go with one.

ultimately depends on your budget and how you plan to use the car (street/track). Unless youre on a super tight budget i would say 'do it right the first time' and get garrett or similar. I feel like this is one of the components you should get geniune, but thats just me. You can pick up a lightly used garrett or nissan turbo for pretty cheap

So y'all think the chinacharger 2871 would be worth it. I'm already building a forged 1.6 with oversize valves?

From my experience and the research I did, I found that pretty much if you buy a ball bearing china charger, it will fail.
However, if you buy a "wet float" or journal bearing type, it will hold up.
I own a Garrett Journal bearing, so I guess I have the best of both worlds.

chinacharger you'll most likely be alright, just get one that others have used and tested so far. I'd look at either the speedyracer "2871" or godspeeds "2871". Godspeed has a lil bigger turbine housing im pretty sure, other than that they are pretty close

Almost every single Chinacharger I've seen significantly less torque under 5000rpm than a comparable Garrett. There are exceptions to this rule, but for the most part that is the rule.

If you are spending money on a good manifold, a standalone, a nice 3" exhaust, a good clutch, and all the other bits and pieces that make up a quality turbo setup, you'd be a fool to run a cheap, sub-par turbo IMO. You don't have to shell out $1k+ for a Garrett DBB, but you should at least run something like an SR20 T25 or another used Garrett in a size that fits your goals

Pay $550 and get a fucking borg warner airwerks turbo.

Something like this cute little thing

Buy blown SR20 T25 for like $100, buy new DBB CHRA for $500, have pretty much new 2560 for half price.

T3 60 = my recommendation
Push more than a T25, easily found, t3 flange, older garrett journal bearing and they came with carbon seals standard on some models instead of dynamic seals.



That S246 is interesting, wonder if there is a compressor map for it

I'm looking for a 2871, so I guess I'll be saving for a true garrett. I want all the torque I can get.

Cheap. $500.

That looks like the map for the 56mm actually

From what I can tell, a chincharger is a lot like using an older turbo.
The design and quality of the wheels have come far enough that their is a measurable difference in performance. That being said, you can still do very well with a chinacharger.

Get a journal bearing churbo and you have a very good chance that it will be reliable.
People burn up Garrett turbos too. Its hard to tell if all the burned up chinachargers failed because of inherent design or because the people using them didnt provide them with a proper oil feed/drain.

Given the money, I would have a superior turbo to a china one. Now that I have decent internals, I would go better. IMHO, a bb 2860 like Trey has, will spool better than my turbo which is smaller, and our boost thresholds, well they are about equal, and I have a smaller one. But.... My turbo has been good to me, and made enough power to blow the stock internals, and wasn't too bad on spool or TQ. A 400 dollar 2871 seems awesome, but when a better, smaller turbo makes more power than you... I don't want to hear it.

I wouldn't mind a turbonetics but I need a t25 exhaust flange. I already have my downpipe.

I have run both Garrett and China Chargers. I actually still have my old original .42/.48china charger that came from ss auto chrome. It made 184.4 WHP and 184.2 Tourque on my old civic at 12PSI. It saw tons of abuse and I never let it cool after beating on it. It never saw an oil restrictor and it still has almost zero shaft play. It's actually in better shape than the SR20 turbo I bought for my miata build.

I upgraded to a Garrett T3 .60/.63 57 Trim and it was useless. Great turbo but too much for a 1.6 on the street. IMO, proper sizing of a turbo is more important than the name on it. I would buy another china charger in a heart beat.
