Just picked up this Turbonetics T3/TO4E 57 trim .63 a/r exhaust up for 150 bucks online. Spins freely and was used last winter. Only issue is 1 blade is bend slightly and one is chipped . Do you guys think it needs new wheel and balancing or can I get away with one season on it like it is? I realize that one gram can throw it off balance and destroy motor /turbo.Just wondering what you guys think. How much is it usually for someone to rebuild this? Pics below , Thanks for your time guys

 

Yes, they need to be precisely balanced, and that will definately throw it off.

 

1 is chipped but all the blades have leading edge damage. That wheel does not work.

 

Thanks guys , how much does rebuild usually run?

 

just get a new wheel. unless u want to rebuild the whole thing.
new wheel, balanced. done.

 

and be careful those shaft threads are usually reverse threaded!

 

Thanks eg6 , I plan on new wheel and balance. Where can I find the exact wheel I need ? Should I call Turbonectics ? Someone said these r same as a garret model.

 

hold on i know common sense might tell you scrape it but i fixed many worse blades on turbine engine. the question is can you fix it and drive with it YES you can. your going to lose performance no doubt. if you plan on buying a new wheel try clipping and blending that one, run it and if it doesnt work you got a new one anyways. if you want to give it a try ill give info on how to clip and blend.

 

Damn that looks like crap.

 

yea im interested 93 slv.
Is this from balancing? I hope so . Back side of comp wheel , just removed it sence it needs new one anyway.

 

he already knows its damaged. im not telling him its not and im not telling him that this will fix it. im telling him he can make it work (cant tell him how the turbo will flow) until hes ready to buy a new one.

 

Few More pics for u guys

This turbo is for project motor for my swap. Not on a car , got a Big 16g on my daily now guys

 

this is all TURBINE theory. ive never dont this to a turbo. gona hook you up with pics so give me a sec

 

tools:
tin snips, neutral (no left or right hand you dont want an angle on it)
metal sanding file, coarse and fine.
ruler, if you can find a lil metal 6 inch ruler that would be great but you need some kinda ruler

step 1: you want to cut as much of the damage area as possible WITHOUT taking to much out. like this


step 2: measure out from the center (along the top of the leading edge) to where you cut. then measure from the root (where the blade meets the wheel or bottom) to where you cut.


step 3: repeat the steps backward (measure then cut) to the blade 180 deg (the one right across from the damaged one).

step 4: you want to file (start coarse the then fine) the cut you just made down so that there is no high metal and so that the pitch of the blade matches the others as best possible.

as for the blades with the leading edge damage follow step 4

 

If you don't want to replace the wheel you can build the chips up with weld and reprofile it and balance. I've done it many times for rebuilds at work for oddball turbos with no readily available wheels.

 

Thanks man but sense its already sitting here and not on my car n needed im rebuild it seals and bearings and have it balanced . Are there upgraded wheels available or just garret one?

 

Just the Garrett ones. You've been PM'd..

 

kk got u back lemme get ur wheel

 

Can't see op's pics...wanted to see how bad this is.

 

Wow, I am never buying a turbo off of 93lsv turbo or sdubfid... Christ.

 

All I could here was dude saying in a last zohan voice, "I make the blades silky smooth." Snip snip

 

hahaha yea man ive done it quite a few time to turbine engine. of course there are alot of differences but the main theory is the same as far as the compressor.

here is a t701c i just finished clipping and blending. 5 axial 1 centerfugal compressor rotors

i wouldnt do this to my turbo. it would KILL the performance of the compressor. the question was could he make it work and the answer is yes.
