14b Is Dieing

[MATCHBX]

As long as you use the same wheels I don't see that being a problem. Unless the wheels are damaged. If they aren't, then it would be "almost new" when it was rebuilt.

The turbine and compressor wheel are balanced as a unit. You would have to mark them. Even then I would look into having a turbo shop balance it. 170,000 RPM is as high as the compressor map goes for the 14B. If 2 oz's can make your car shake horridly at around 900 RPM (on the tires) imagine what being little off balance at 188 times that speed would do. :stick:

I understand that Ryan. But what I was getting at was that if it is a 14b in GOOD condition, this obviously means it has minimal shaft play, does not use oil, spins freely and has had no foreign objects go thru it. With that being said, why would the original wheels of the good one be missing any weight? If so, it's not that GOOD of a 14b. I agree that it should be balanced but if it was good from the get go, a refreshening of the seals and bushings is not going to throw it out of balance.

BTW, what is the cost of balancing those wheels? Just out of curiousity.

well thanx everyone, i guess this seems like its a lil too much of a job for me, ill just run it till it dies, but thanx for the responces

So basically, if you find one that is used and in decent condition. You could rebuild it for about $200-250, price including rebuild kit (provided you could do the work yourself), and you'd have a nearly new one. Would that be acurate? Was I right in saying the rebuild kits run about $100? That's just what I thought I had seen on a site somewhere before. Do you guys have any links to sites that sell rebuild kits? I used to have one but I have no idea where it went.
If you get one that is in decent shape, why would you rebuild it? If he were to rebuild one he should get his rebuilt and save the $150 on another. I may have another lower return line laying around if anyone needs one.

Because if you buy a used one that is supposedly in decent shape, you have no idea if there may be a problem with any of the seals (orings and such) until you bolt it on and try it. I have never found one that I've pulled apart that the orings weren't completely hardened from age and heat. Plus you also have the added satisfaction that you know what it looks like inside. Plus you have the reassurance that it will last for quite a while.

I mean, would you buy a low milage engine and just stuff it in your car without at least dropping the oilpan to see if it's ok? If you open it up, you might as well refresh the seals while you're in there. I think any engine rebuilder or car mechanic will back me up on this one. If it's used, make sure it's good enough to last for a while before you bolt it to your car.

thanx again for all the replies, but i think imma just drive the car easy like i always do, and once it kicks the bucket, ill prolly just be throwing in a pte 50trim. thanx

I agree with you to some extent. Why would you buy another if you are planning on rebuilding it though? Why not use the one he has?

If I were buying a used engine, the first thing I would do is get a warranty from a junkyard or something. Yeah, I would drop the pan but I wouldn't rebuild it (pull the pistons, replace the rings, do a valve job, etc.) as long as it is out of the car. Why wouldn't I just rebuild the one I have instead of spending money on something I dont need. See my point now? You would just have another lying around. If your plans are to rebuild something and you have one needing a rebuild, why buy another? IMO just a waste of money.

I would stick with the turbo you have. Check it for shaft play and get a used one if nessecary. Dont assume the turbo is burning the oil though. Check the return line gaskets and see if they are leaking. Just a simple look under the car.

[MATCHBX]

I understand your points. I didn't mean that you rebuild the engine, I just said to refresh the gaskets (seals). It's much easier to do it when it's out.

And the reason why I say rebuild the used turbo (seals, not new wheels and such) is because if the old turbo that is burning oil is so bad that it's gonna take extra parts (more than just a seal kit) to rebuild it, then it would be easier to start with a unit that is in good shape where you would only have to put in minimal items (only seals).

I guess this comes down to symantics. Maybe I should've said that you should "reseal it" rather than saying "rebuild it."
