Is this turbo worth using??? (56k might take a bit)

[crackler]

A freind of mine gave me a t25 and a smic out of a 95 talon for free.

It has 2" inlet and oulet on the compressor.

my question is, is this thing worth using?

I am new to turbo's, I have been looking around DSM sites trying to find info on this turbo. It was originally on a 2.0 liter that made about 210 claimed hp, I assume bhp. I still havent found what psi the internal waste gate is set at.

I think it has a t25/t28 flange. And a ported inlet from the exhaust side (where the flange bolts to the mani)

This is a garret unit, at least that is what the metal tag on it says.on exhaust wheel it has .49 n55 439 h2 (exducer 1.590 inducer 1.830)on the compresor side it has .48 m10 1 (exducer 2.055 inducer 1.525)

I assume the first set of numbers are the a/r or trim? I dont know what the diffrence is any way, but I have no idea what the rest of the numbers are.

I was planning on using both the turbo and the smic, fuel pump, injectors, fuel controller,(possible safcII), bov, dump pipe, boost and other misc gauges and possible a mbc, and all of the other associated parts (water lines, oil lines etc etc)

Sould I use this thing or should I just wait save up and get a bigger turbo?

I would like to be in the 230 - 250 whp range. I don't really want to run more than 10psi, I was planning on running around 5-7. Is that a resonable expectation with this set up? I do alot of autoXing and some HPDE's so I want something with quick spool up.

Please give me you opnion, I know enough to know I dont know.

Surry for the long post.

Thanks.

you will start losing hp on the top end. Go with a t28 or better

Thanks, would it be worth using at all? I dont spend a whole lot of time at redline, except for autoXing.

Any one else have an opinion or experience with this or simillar setup?

coming from DSM's to nico, i can tell you that the t25 is absolute crap...+1 for the freebie, but it runs out of flow on a 2nd gen DSM...most guys upgrade to the 14b off of a 1st gen, and even that unit is pretty small, i cant remember exactly, but i remember people maxing the 14b out at ~275ish hp. but that was at like 15 psi, so not healthy for that turbo. the t25 flows much less than that. without going to look anything up i would say at 5-7 psi i would expect 170-190 to the wheels. but you are right, it should spool up almost instantaneously. sorry for the vague answers, but i havent been on any dsm boards in almost a year

RUN! Stick that turbo on Ebay and get it gone really quickly!

[crackler]

superdrifto:That is kind of the idea I was getting from looking at the DSM stuff. I couldnt find anything about t25, everything was about the 16b? and some other turbo, so I assumed every one junked the t25 for those other turbo's.

My buddy that gave it to me is going with an evo(?) turbo.KATwo40I will check with my buddy and see if he would be pissed if I sold the turbo he gave me, if not off to ebay we go.

How much would be a reasonable price for the turbo and the smic???

thanks

[KATwo40]

Prolly couple hundred bucks or so on Ebay for the SMIC and turbo.

[crackler]

thnks

[superDorifto]

yeah, everyone ditches the t25 because it can barely support the stock boost level (12psi). DSM guys go with either the 14b, off of a 1st gen eclipse, or the evo III 16g (off of the earlier evos), which is a much better fit for the engine's VE. i was going to build my ka-t with a 14b, but thats a different story.

[Mustangs_Suck]

I don't get all the T25 hate. It's a cheap *** turbo for decent power.

I'm boosting at a whopping 7psi on an old and tired out turbo AND motor and put 200rwhp and 205rwtq on the dyno. For a light, manual, RWD car it's plenty of fun.

As for the DSM T25 I don't know how it would fit correctly, so you'll have to wait for that answer.

I use the T25 off of the SR motor which is completely different looking, but in essence the same turbo.

[KATwo40]

DSM and SR T25's aren't the same.

[Mustangs_Suck]

DSM and SR T25's aren't the same.

they are in aspects of boost levels, power and how old they are pretty much.

The size/shape of them are drastically different though.

The SR T25 is a fine cheap turbo for the KA. The DSM T25 - if you could get it to fit/work would be fine as well, but i don't know if it's possible, and i'm sure it'd be easier to just sell it and buy a SR one.

[Chezedik]

No they aren't, the trims are way different. The DSM runs out of steam hard on a KA, but people have done it. The SR with the .86 A/R is a much better bet.

Dont quote me but arent the DSM T25s water cooled as well??? I know the Stock 14bs off 1st gens are because I ripped apart a 1G motor and had coolant all over me when I removed the turbo

[hannibal]

^ It looks like it from the pics, but dont forget SR T25/T28s are watercooled as well...

Now thats some new info for me... you learn something everday

[FerretsCanDrift]

Yes they are also watercooled. You can use the side mount since you got it for free. The only thing is the inlet/outlets are set up to have the IC mounted on the passenger side. They really arent too bad for the numbers you're looking to put out. My 1G runs high 12's with the stock side mount and its just about maxed out. Do yourself a favor if you decide to use that turbo. Get a downpipe made to the turbine housing instead of using a dsm O2 housing from the turbo to the downpipe since its a huge bottleneck

[S13 240SX]

I was gonna use that same turbo! But then I went and got rid of it, and got a 14B turbo to use for on my sohc ka, but i'm most prostive using that turbo or a 14b, with some head work and it'll flow just fine, and your re-gain the HP at top-end, by just upgradeing the the cams. At least I think anyways cams would re-gain the hp loose at the top end... Someone correct me if i'm wrong on that.
