How much and how hard would it be to rebuild a t25. I just picked one up for 50 bucks but it has way too much shaft play... So, how much and how hard is it to rebuild a t25?

please, dont suggest another turbo...i already know that...lol

Seriously another turbo this is why, a turbo that has extreme shaft play specially the in and out type and up and down (for that matter any extreme play at all) is toast, most likely if you were to take it apart you would probably find signs that the previous owner did many hot shut downs and the CHRA is coked up and the carbon deposits have chewed away at the turbine side of the shaft rendereing it a useless paper weight, reason being is becasue you would have to replace the shaft which is one piece with the turbine wheel and is very expensive even if the turbo were FREE second you would have to buy a new compressor wheel which cost money to but not as much as the turbine?shaft/wheel which is one unit.......FYI Key here to anyone reading this is to rebuild your turbo at the very first sign of any kind of play.

T25g rebuild kits can be had for $75 balancing the shaft about $30 so it cost about ~$105 to rebuild a turbo that has very very minimal play that wasn;t abused but one with tons of play a rebuild would probably run around $700 dollars or so depending on if new or used better condition parts are used.

excellent write. Thank you.

There's also the option of taking it to a turbo shop and have the guts replaced with upgraded parts. I believe Turbonetics does a pretty good job at beefing up stock t25s. But then again, for that price, you might as well get a bigger/more efficient turbo.

it's probably better to find a journal bearing turbo for cheap, that rebuild is chump change,

Im sure the thread starter's T25 is a journal bearing type

Its only chump change to fix if its a good used condition T25 like I talked about above very very minimal shaft play, as far as I know they do not offer a rebuild kit for ball bearing turbos.

Turbo Performance in Van Nuys, Ca rebuild my junk T25 for $300

Dutchmalmiss · 04-11-2007, 02:29 PM

^^ nice, stock specs??

gotta240 · 04-11-2007, 05:19 PM

yeah, is it at least a better turbo for 300, or still original?

Nikeboy355 · 04-11-2007, 07:30 PM

Turbo Performance does a great job...

And that turbo will run just like a brand new one... If you want to get more performance, he can machine the housing to fit a larger wheel...

Really nice guy also...

Suk02Si · 04-13-2007, 03:16 PM

Just all stock components. He had a couple T25 laying around and assembled one good one. He even had it done for me in 1 hour b/c it was a fri.

I've rebuilt my t25 it is easy. Get the e-bay kit and a pair of tweezers, a t-15 sized star fitting, and a strong ass vice.

unbolt and pull off the turbine housing, then clamp the weird shaped thing on the end of the turbine into the vice.

remove the compressor housing, then your down to both wheels and the center cartridge

you must remove the nut holding the compressor wheel, remember it is reverse threaded!

anyways, break it apart, use the t15 star fitting to remove the thrust bearing and pull out the shaft and bearings, etc..

rebuild.

Also to keep the compressor wheel "balanced" mark the blade with the shaft so you can realign it when you put the thing back together again.

ITS EASY!

sweet. Thanks!!! You didn't replace the shaft though? Is it necessary?

opponheimer · 04-14-2007, 09:19 AM

Not really, the bearings are what need replaced.. unless the shaft is scarred/bent/etc... . When you hear the term "shaft play" its because the bearings are worn. But dont take my word for it, you really have to open it up and find out. Open it up!
