I have a garrett tb2210 I got in a trade.

It's in great shape but I'm not sure what this sucker can do. I know that this model came of a 90 to 94 300z, so that's about all I can come up with. Think that makes it aT25.

It has a .48 cold side and a .63 hot side. Yes I know it's a lil' guy but I can give it a good home somewhere if I find the map to show me how far I can push it.

Anyone have a compressor map?

 

Its just a t25 with a small compressor housing

Unless it's going on a small non vtec d series you'd be better off selling it. I have 6 of them, 4 upgraded. They're only useful in pairs as twins

 

That's because Nissan never publicized their maps outside of Honeywell's facilities. Garrett made certain specific turbos for some OEM and Aftermarket companies (like HKS) in which their maps weren't ever made public.

Mitsubishi Heavy Industries, on the other hand decided to because they made their turbochargers entirely through their own OEM division. Which is why you can find most of their stuff online now.. but even then, not everything.

Those turbos originally came as part of the RB20DET R31 and R32 GTS-T models as well as the VG30 300ZX. They did not have any A/R Markings on their hotsides typically and were a T25. The one you have is more than likely the one that uses a slightly smaller compressor inducer but larger exhaust housing than the RB25DET model.


These TB2210s were the largest of the RB/VG series turbos from that year. (There was the TB2206, TB2207, [AUTO TRANS] and the TB2209, and TB2210 [MANUAL TRANS] for the 300zx. The measurements of the turbine housing from what I remember were in 9cm and 10cm housings. (If you have a photo to show otherwise, i'd like to see it please, because what you're describing by way of housings are T3 and not T2 which is what they actually were.).

The TB2210s were about 304cfm (28.9lbs/min) at over 2PR and did about 210whp MAXIMUM. maximum efficient boost pressure was about 1.2bar (about 17.4psi of boost pressure), and that was with a low-flowing cylinder head.

The ABSOLUTE CLOSEST you're going to get to that turbo by the way of compressor map is the GT2252, as it is the closest thing to the measurements of the TB22 using a .67 A/R in the T25 flanging, and compressor/turbine wheel measurements. I happen to still have those measurements from about 13 years ago..

This is about as good as it gets.. When you use something like that on a honda, you get VERY mediocre results, but it depends upon what you're using it on. A snowmobile , awesome!! a Car, not worth the effort to integrate them.

You could possibly run that at about 14psi to make about 170whp in total, but don't expect much.

Good luck.

 

I know this much. What I don't know is how far I can push it. Cars aren't the only things I like to turbo. I might like to use it on something else like a bike or other small engine.

I need a flow map so I can see what it will fit for power and pressure maximums

 

Exactly. I figured you'd have at least a few of those lying around.

 

I just told you what they were. They have been bold and highlighted for you. You are not going to find a NISSAN Specific Compressor or turbine map.

 

Shodan do you have email I can send it to? I'm in mobile phone and can't use a computer for awhile. Fire station rules say no computer access for this kind of stuff.

I don't know much about the technical details of turbos. I just build and weld based off what a company saysfits. This is something I'm just looking to play with since its "free"

 

But in this case, the power level of those turbos is VERY mediocre for most engine applications. It was "free" because the person who gave it to you couldn't use it either, because they didn't have the flanging and other materials needed to use it. or the internals on it are bad and not worth the cost to repair/rebuild.

As I've always said.. "Just because its free, doesn't mean its "free"

 

You have email with 4 pictures.

 

Received. For future reference, since computer access is limited, if you have a smartphone and a Photobucket account, you can directly upload photos from your phone and add them to your account and post them here with the [IMG] [/IMG] on each side of the link.

Ok.. onto it. Well, it seems as though I'm not completely wrong, but not altogether right. I'm only going further because of the fact that I have to make some presumptions as part of the premise.

It looks like this turbo is somewhat of a hybrid if this is indeed a TB2210. The best thing to do is to take it apart and measure the wheels themselves to determine what it is using a caliper to determine if its the TB2210. There are diagrams on the FAQs on how to do that.

But let's assume for a minute that it is a TB2210 from a 300ZX. IF it indeed is a TB2210, then They took the TB2210 and substituted the 4bolt turbine housing with a .64 A/R (that's what it says on the housing) from an S15 SR20DET (or a post-1996 S14) that is also a Nissan 4-bolt. The housings from the Silvias did allow their markings to be shown, unlike the OEM 300ZX and still fit the same turbine wheel.

In addition, Nissan didn't have a .48A/R compressor cover in their line, (at least from my database records from Nissan and Garrett combined), if they did, It kinda doesn't matter because we're still assuming that this is a TB2210 turbocharger which came with an unmarked housing and the compressor housing of these sizes do NOTHING for power on these compressor wheels. It could be a .49A/R from a CA18DET, but again, not the most important to know.

If it isn't a TB2210, then it could be a FULL post 1996 S15 turbo with a swapped compressor cover that was machined out, because they did share themselves with the VG 300ZX and Gloria, although these never had markings on their housings. This is what makes me think its NOT a TRUE TB2210 from the VG and more like a TB series from the Silvia.

Ok. so what does this all mean? In the end, NOT MUCH.... Whether its a TB2210 from a VG or a Silvia, or a swapped compressor cover from an S15, "A good home" is back into their respective cars. Like the Subaru WRX 2002-2004 WRX turbos, they were best left to them and no one else. Their upgrades were typically just an STI VF39 anyway, and really couldn't be used on anything else to get any power.

So, for hybridracers, this means the following:

1) Your BEST case scenario is hopefully that it is a true TB2210, as it was good ONLY to what I stated before, about 160whp or so. A lot of Honda engines can do that already NA, so it may be the case that the VTEC cylinder head actually outlfows the turbocharger's capability!!! .. which is a waste of time and effort on your part.

2) Forget rebuilding it.. These used a full Garrett steel cartridge that was only available on NEW units. Taking this apart and "rebuilding it" is out of the question. Its better to get a new one than to try and fix that, if there's anything wrong with it.

3) Maximum boost pressure is 1.2-1.3bar for ANY OF THESE MODELS (17.4-18.8psi) AND THAT'S IT. After that, you're simply blowing hot air, and since they only can flow No more than 304cfm (29lbs/min) for the largest compressor wheel of the TB2210, You've got NA cars that can do that without any turbocharging at all. Even if you run "10psi, just for fun", it won't be fun at all. You'll just have a turbo to say you'll have one, it really won't do anything for most any B-series, and at BEST a small little D-series that just wants more than 130whp. Because that's all its going to do.

To find a weld flange for that turbo will be IMPOSSIBLE, as its no longer produced by Garrett, and you'd have to find one from an OEM VG/RB20/25/DET downpipe, and then utilize it in something that fits. Even the Jim Wolf Technology upgrades for that were VERY expensive to a point that they... just aren't used anymore except for VG/RB20/25/DET people. And even that would be as a replacement IF its in good order.



In essence, you got this for free for the same reason why most people get a "free turbo"..... Because the person that gave it to you can't use it either, otherwise, it would have value and would have been sold to you.

Your best bet is to sell it as a replacement for Nissan VG, SR20DET, or RB20/25DET that wants a stock turbo for nostalgia or restoration, or use it on a snowmobile, pocket bike, grass-racing lawnmower, moped, or custom go-kart (my personal choice )

*Sigh*.. I've gone as far as one would be willing to go... so, if there are those that know more than what I've given, they're welcome to it..

Good luck to you.

 

Tag on center section says TB2210. It's how I figured out what it was at all.

Wont be used on car at all, I'm thinking more about using it on my motorcycle engined dune buggy.

So if it's capable of flowing 300, according to garrett, it should be okay to produce the 170-200 hp. At what pressure I dunno.

As far as flange, I immediately noticed the 4 bolt side. I will cut my own via plasma or have someone laser cut one.

The hot side is actually marked .63 it's even stamped on the throat internally.

I certainly thank you for the help. You've given me much more info than I've been able to find. I think I'll run it and see what she does. If I don't like it, I'll just let it sit in the garage and mount a known good t28 in it instead as it looks like the same manifold flange.

At least this way I have something to do. Its no sweat off my back. As long as it boosts a small engine it's not useless

Thanks again

 

I've listed what the turbo can do... Twice. Please re-read. it was right next to the 304CFM flow rate and I listed at what boost pressure it would do it in... In Red.

Those photos look like a .64, and make sense for that cartridge. No such thing as a .63 for a TB2210, unless it was a misstamp.

But I'm glad it was figured out. Good luck with using it.

 

it would be a fun midrange turbo ( 2-5k)

zero top end.

zero.

 

Shodan thank you for the help. It's been greatly appreciated.

I'll post results as I build. Will have to gather up some parts. Would rather go past the turbo than melt some cylinders down.

Like I said it should make enough power on a sub liter bike so for everyone else telling me it's a waste of time I have nothing to lose using it. Plenty of small engines to play with in my world.

 

There isn't a nissan map because it's a garrett turbo... I can tell you this, past 12-14psi they are hairdryers. They pump nothing but hot air and the gains stop.

The 2552map is over zealous, the t25 isnt that efficient

Manual z32s had .63 turbine housings while the autos had .48 turbine housings.

The turbine wheel is the limiting factor, and define sub liter bike. This turbo is too small for even a 600, try a 250 and you're close. Bikes have insane volumetric efficiency (over 100% ) I could run a t3/t04e 50 trim and outspool a 2 liter motor and literally vanish before you ever change gears

The only thing you can do to help the turbine side ia clip the wheel 10-20 degrees, or go to a larger wheel and machine the housing but the cost involved makes the attempt moot

I have 2 that have t3 60 trim compressor wheels in stock housings with a clipped stock turbine wheel, and then two have gt28 turbine wheels and gt2860 compressor wheels in modified rb25 compressor housings (jwt sport 600s)

This turbo wont do what you think it will.... youd be better of selling it on eBay

Trust me on this, me and TheShodan are turbo whisperers
