any one running this turbo setup what are the pros and cons

 

Pros: 20g makes decent power

Cons: old ass Turbo technology, longer spool time, expensive (hahn), there are better kits.


Go with zap, synapse, or bytes kit. Or better yet piece together your own.

 

yea don't go with the 20g, old tech, i am looking into doing a dirt replacement and zap is working on something like that

 

As already stated...

 

Its too tiny. Isn't it journal bearing and internally gated..

 

why waste money on an old-school journal bearing turbo 20g......if you can get a ball-bearing turbo?

 

Price? 20 g is old yea but still flows what 47lb of air ? But yea prolly better options.

 

It'll be expensive (hahn) and will be outperformed by nearly everything else available. The last guy who went through them to get their full setup had a nightmare of a time getting his car in running order. Weather it was his fault, Hahn's fault, or his car's fault...I don't know...either way my first sentence pretty much sums up their kit.

 

I rather get a gt2871r.

they're very cheap these days........

 

Chevycobaltss3 (james) ownz that car, now.

 

Yep I had to fix all 7384858483838384848 things wrong with it. Turbo wasn't one.. lol... Tune, mainly was. It wasn't a Hahn tune. It was tuned by someone else before I bought it. I won't mention names. But the s20g with a td06 shaft and ect has great flow. Yes its old news but you can pick 20gs up pretty cheap. If your not wanting more then 400-440 the 20g is fine as long you have supoorting mods and run e or Meth. I am ribbon.g the td06 25g wheels and it flows a bit more air... but all in all.





**** Hahn ****... It's b.s with all the Hahn **** I replaced due to the lack of love and care they put into there mods. I blew the innercooler up too many times and there charge pipes and intake suck as well. Exaust rattled so I go magnaflow. Downpipe is good . That's it.

End rant

 

Awesome guys thanks

 

Get the ZZP EFR Kit when it's released. Less than 2k for the bolt on kit.

 

if it ever comes out.....

 

I dont see less than 2k. All the r&d the turbo retails between 1400 and 1600 I could be wrong but just not getting my hopes up

 

luckily zzp themselves said that it will be less than 2k. if it isnt then they just lied to us all.

 

I bet they're getting a bulk deal on the Turbos...also when a product is finalized you can make it a lot cheaper using different methods. The most expensive stage is research and development. Once they develop a solid design and get their bulk in they can probably start mass producing.

 

Its amazing how some people don't see and understand that. R&D takes time and money.

 

There is so much mis-information here. I know this is an old thread but some things need to be cleared up. The 20g is suprisingly an incredible turbo for old journal bearing tech. The powerband is very nice and makes 420 on the stock fuel system with nothing more than 80lb injectors and E85. Now price is an issue cause the hahn kit is priced near zzp, meaning zzp is the better deal. When they are on sale for 4000 or used kits can be had for 2200 (what I paid). They are a steal of a deal. However if you come across a good deal on a 20g its well worth it. Also forums swing the way the wind blows so tomorrow it will be some other company that is the next forum fad. Anyway I have the hahn kit, never had to fix a thing on the kit other than getting a -12an fitting for my oil return and taping the oil pan. The hahn kit made 420hp and made 395 ft lb of torque from 4500 all the way to 7000 on stock fuel system. return style will hopefully get me another 20 or so hp but that is for later. I am just enjoying the car after having it sit for a few months during my engine build.

Hahn quality is far beyond anything given credit for. They did have manifolds crack but they were all replaced under warranty. I have the warrantied version and its heavy and thick aluminum walled. The tubes do route nicely under all sides of the motor and dont get in the way of anything. However, zzp kits require you to remove the piping to pull the valve cover, but people dont go bashing them for that. Their intercooler is way overbuilt for the 20g and doesnt even get warm when making full power. I saw only 20 degrees IAT change from vacuum to 27psi on the dyno with a small blower fan in front of the car. It has been said that the piping is too heavy. My turbo kit weighed in at 60 lbs, my supercharger shipped with all the parts was 100. I shaved 40 lbs off my car just with Hahns turbo kit.

Anyway, HAHN doesnt get on the boards anymore because of inter-business rivalry, but myself and a handful of other guys are running these kits with great results. I think mexiloco, 07lsj, jonathan923, and a few others who dont frequent the boards have all liked their kits. Its just not the latest greatest ball bearing turbo so its overlooked. I didnt overlook my kit when a guy on here let it go for 2200 with a rebuilt turbo.

Just saying keep an eye out for them, we drive budget cars, there are always good deals coming along and a 20g is not one to overlook.

I might add that this was an LSJ kit. The LNF kit is even cheaper with the same turbo.

 

Good information here, will look into their kit further.

 

What i dont get is everyone saying "old ass technology".......more people in this site have a journal bearing turbo than a ball bearing turbo. The bnr 2876 is a journal bearing. The 5557 that most have is journal bearing (not the dbb cersion). The bullseye turbos that zzp sells are journal bearing. Now the 20g does not have a billet wheel like the 5557 and other turbos do. Its spool time is slow. Sure. But a jb5557 doesnt spool till over 4k either.

Quit ******* it. Its just as good as anything else out there. And your transmission will likely thank you

 

Hey Chris... gimme my boost

 

Its coming....

 

Well said

 

Meh, for the money it's a waste of time. The BNR would be a better turbo if you don't wanna spend all that money.
