What Turbo is this? [Merged] Turbo ID Identification

[BoredOutaMyMind]

OK, from what i know , all 2gs have the T-TooSlow, but for somereason it doesnt seem like mine is all that bad. People talk about losing power at higher rpms, is this boost pressure or actual power, because my lil snail can hold 12 psi all the way to 6500 (havent pushed it past that, on purpose anywho )
Also im not sure if you can hear these spool up, i can definately hear mine, as can people next to me. Anways, i have heard that alternating fins means its a 16g, correct? Well i have pics of my turbo and i was wondering what you all think it is. The reason i ask is because ive found things on this "STOCK" car that shouldnt be there.... such as a hole in the steering wheel boot that was already there when i was about to install my boost gauge.... sneaky things like that. So maybe i got a deal and have a better turbo on eh? .
One more newb question before i go, how does a t25 16g differ from s16g and b16g's... as far as power etc. i havent posted on this site in a long time, but ive been reading up on the boards, hopefully i dont get flamed Thanks in advance.

that my friend is a T-25. im sure your car feels good but when you drive a dsm with even a 16g you will see why everyone upgrades.

 

[BoredOutaMyMind]

<sigh> well atleast its not as bad as people say it is... atleast it doesnt seem that way to me... ive been thinkin about doing the 14b upgrade when i have the time... or money

Oh, on a better note tho, is this a 16g? the best the t25's came in? or just one of the lesser ones... now im even doubting the t25 came in different sizes

yeah even with a 14b you will see a good increase in power.

that looks like a garret t25 or could be a t28. there is no such thing as a t25 16g...there are only t25, small 16g, big 16g, and evo 3 16g. It isnt power that drops off as much as boost. the power drop off is slight and is directly related to the boost dropping off. Flow for those turbos are as follows:
t25:250cfms boost falls to 9-12psi at 5.5k-6.2k rpms no matter what boost is set at.
tdo5 family
14b:stock 1g dsm turbo 405cfms, can build decent doost up to 20-22psi but wont hold past 18psi at redline
small 16g:505cfms, will hold 20-22psi top redline
big 16g: 550cfms will hold around22-25psi to redline
evo3 16g: 550cfms lighter and more efficent then a big, but similar.

the above specs are just rough sketches to give you a round about idea. they are by no means the standard or given results.

From the looks of the pic, that is a T-25. If you want to upgrade withoput having to spend so much money, go for a small 16g or 16g. These are very good turbos and is capable to see 12's or low 12's. Anything bigger will cost more money, I've just put in a T3/T4 similar to a greddy 18g, dam I miss my t-25. I can't afford to buy anything else, my car is so slow for now, boosting at 12psi and does not want to pull hard at all, comparing it to the T-25. Without any fuel system upgrade this big turbo is crap. I pull a 138hp at the wheel on the dino. My mistake to buy something too big for a 4 banger. Even with a 255 Walbro, the turbo still want more fuel upgrade, it still not wanting to pull hard even at 16psi, but pulls ok at 19psi after full cut.

it is by no means to big for a "four banger"...you just didnt do supporting mods, causing your car to pull timing therefore major loss in hp and torque.

Thanks, i had no idea 14b's had so much more flow than T25's, i knew they had more, but not just short of DOUBLE !... this turbo sucks, i need the 14b upgrade

if its not too big, let me know because I'm at the point where I'm broke and willing to trade for someone around my town for there t-25 or small 16g. Is this usual for t3/t4 to not give me good pull backs at 12psi, cause it ain't pulling hard at all. What psi does this turbo pull hard then? I think I like it better when my buddy's 16g pulls without much fuel system upgrade, he ran 12.9 with my greddy bigFMIC 190 fuel pump and bolt on pieces running 21psi.

 

[miteclgst]

I would agree that it is a T-25 and not a T-28. I believe that the T-28 has a ported compressor housing and inlet. This inlet seems to have the same wall thickness that the stock T-25 has. Since you are new to DSMs the turbo will seem fine, once you being to try and up the boost you will see that the turbo just craps out in the higher RPMs. You can set your boost controller at 20PSI if you want but no matter what once you get into the 5K range the thing will default back to 10-12psi like a skipping CD

We need more information. T3/T4 is turbine/compressour housing styles. That tells us nothing about the size of the inducer or exducer, nothing about how much it flows, we have no idea what the A/R is on the turbine housing...

That's basically like me asking why my TD05 isn't pulling as hard as my friend's 20G.

(not that I have a turbo with a TD05 housing )

 

[GSX503]

I'm new to dsm and bought a t3/t4, it said to4 airesearch, inlet is 3" outlet is 2.5", internal wastgate, dsm bolt onto stock manifold, ported, this is pretty much all I know.

There are literally 100s of t3t4 configurations..there are ones rated at 150hp-1000hp

Where did u buy this from.?? My guesses are it might be a 50trim being a 3in inlet. But whos knows 138hp on the dyno thats just not right, even at 12psi.

Ill trade you my t25 ...

 

[GSX503]

I got this turbo from turbochargersystem.com, he said it supports 400+hp. Anyone think I need more fuel system upgrade to get it going. I have a 255pump and its still not pulling hard at all. The t-25 pulls alot stronger than this at 15psi.

 

[UMR98GSX]

you keep mentioning that you have an upgraded fuel pump... what about injectors? Are you still running the stockers?

Whoa come on I wouldnt call him a dumbass...

Just noob or uninformed is sufficient

 

[iboostdoyou]

Whoa come on I wouldnt call him a dumbass...

I think dumbass is about right ... it hurts when i see someone put a turbo like a t3/t4 on their car without doing any kind of work to see if it is right for their car, how to make it work, or even the specs on the turbo. I suggest you put much larger injectors in there than stock, tune the fuel pump, and use a safc... then and only then will you get to see half decent power numbers.

Well- yeah... your fuel pump is just going to make sure that you have plenty of fuel in your lines- not going through your injectors. You'll need bigger injectors- are you still running the POS 2g plastic BOV? How about your intercooler?

There are tons of things you should be upgrading before you even TOUCH the turbo.... especially going to something considerably bigger than stock....

 

[GSX503]

, dumbass.

See guys, Im not a dumbass, and its disturbing to hear people call me a dumbass when their the ones living with there parents owning such a dsm with higher insurance working at local production factory. Look, I am intitle to be getting my Mechanical Engineering degree this year so I guess whos the dumbass.

Look my mistake to go to a local shop to have a small 16g install, yet when I went to pick up my car the following week. The shop had put in the T3/T4 without giving me any notifications. See I only paid $350 install and refuse to paid the rest. Look, we Engineering students are too smart to get fool by shops and also got away with a more expensive turbo for $350 install. I got the receipts if you want to see, keeping reciepts just incase of a lawsuit and trust me, I won't have to pay the other remaining $700.

Dude, I already knew then, that I would need to spend more ok. Thats why I stated bigger turbo needs to spend alot more money VS small 16 and 16g.
Riding around burning so rich and smelling like raw gas is not fun at all when I'm a full time student was small amout of budget.

And yet my cars is paid off with through my Engineering scholarships and grant money, so don't call me a dumbass when you don't know me.

Look I'm just trying to help here. Its really not safe to driving, when running too rich and can't afford to buy more things for the car. Its just not the pump that will get the car not to run so rich: its the injectors, safc, fuel regulator and plus many more. These are $$$$$$$$$, pretty much need all of these right away.

 

[oldman]

Ill trade you my t25 ...

proted 16g here, better than his t25.

I got my EE degree 18 years ago, I live in my own house, I could have kids as old as you, you "dumbass" Relex kid, everyone is just trying to help you, in a very funny way. :laugh:

 

[GSX503]

Yeah I'm relaxing, I just don't like it when people call me dumbass when they don't know me.

I'll trade but you guys are too far away. Plus, I will only trade if they are willing to pull turbo in and out of my car and installing there trade and trade should have no shaft play. My turbo is only 3k old and never seen 19psi.
Turn down to 6 psi only. Too scare too blow my motor, the richness is already scarying me.
When running for a 100 mile distance or some period of time, it produce blue to white smoke from the tail pipe at idling. Cause are from running too rich, a/f at last green, similar to when my o2 sensor went down and didn't replace for a while, this will cause bad fuel trim. Thats what the dealer said when they inspect and replace the o2. I know its easy o2 sensor but I don't have the time play with it. Its better when the shop checks it and replace it while I'm in the waiting room studying.

GSX503,

Find a local DSM'er that knows what he is doing and see if he can help you out. Look at his car and try to understand how his various mods support his bigger turbo.
