K03 rebuild

[BryMFL]

Looking to buy a new K03 and rebuild the one I have. Anyone know any DIY's on the rebuild and how difficult it may be. Anyone have experience with www.turbosandparts.com ? They got a new K03 for $300. Is this a normal price. Also after doing the rebuild is there anything else I need to do to the turbo? And how much oil will I loose taking off the turbo?

[HIERLEVELZ]

Why buy a new one and rebuild the other. Just buy a K04 and call it a day.

why rebuild a k03?

[b6a4]

buy a ko4 im sure you can find a really cheap ko3 replacement on here. post in the wanted her and on the vortex. you should be fine on the oil as long as you dont turn the engine over and plug the ends of the lines.

[BryMFL]

Cause a K04 is $900 alone, plus being a typical man I would have to buy all the supporting mods with it and that adds up to be a little more than the price of a rebuild and new turbo.

[manhertm]

Well buy a rebuilt K04 and use the money saved to get some injectors.

Just Paid 600ea For K03.k04 You Will Need Alot Extra Not Just Injectors Running A Couple G's,most People Just Dont Get It They Think You Can Just Buy A K04 And Put It In,not The Case

[HIERLEVELZ]

A k04 can be run w/o any supporting mods as long as the car is running stock boost/programming. Its a K04 not a GT28.

Why bother putting one on if your going to run stock boost.

Because the OP may not have the funds to "upgrade" so rather than waste money on another K03 he can put a K04 in and still be able to upgrade at a later date.

[manhertm]

Ok Ok, to the OP, are you chipped already? Do you have any mods? Do you plan on modding your car for performance at all? If so I would look into a K04. If your pretty gonna stay stock or stage 1/1+ chip then go with the K03.

[BryMFL]

I have no mods YET. Right now I'm just looking to stop the turbo from leaking oil. I would like a K04 but have a lot of other things to pay for right now. In the future I will just buy the entire 2/2+ upgrade in a package. For now it will be the K03

The center section rotating assembly is the same, but the turbine and compressor housings are different. The turbine and compressor housings can be swapped out to convert the center section/rotating assembly.

Another place for a rebuild kit is gpopshop.com, they also sell new k03, rebuilt k03 to k04 spec, or will rebuild your k03 to k04 spec. Just some more options for you.

[BryMFL]

So I decided to rebuild my K03. I ordered the rebuild kit from gpop shop and they were very helpful. I hope to rebuild this this weekend and hopefully do a DIY on it

Sorry to bring this thread up, but wanted to ask BryMFL how hard the turbo rebuild was? Im highly mechnical but wanted to get your take on what it required to do the K03 rebuild?

I have a leaky K03 now where it seems like im loosing coolant and a little oil, and was thinking of just rebuilding it instead of buying a new K03.

[Drives_to_fast]

did you ever find out how hard it is?

It is very unlikely coolant is leaking from the turbo. The center section casting would have to be cracked if coolant where leaking from the turbo. Cracked center sections are practically unheard of.

Rebuilding a turbo won't fix the leak if the center section is actually cracked. A new CHRA would be required.

Borg Warner K04-015 CHRAs are less then $300 brand new FYI.

Not entirely, sold the cars years ago. The coolant leak wasnt due to the turbo, it was due to the rear coolant flange. So we fixed that and took care of the coolant leak/loss issue.

Oil was still being lost but car was sold before we investigated it further.

However I will say this, My father has a 1991 350SDL Mercedes, and that turbo was leaking oil (its an oil cooled turbo only, no coolant lines going to it). I removed it and we entirely took that turbo apart and rebuilt it at home with nothing but hand tools. Rebuild kit was only $75 for that turbo. That is basically a T03 turbo so basically the same thing. Comes with new journal bearings, seals, snap rings, bolts, orings, etc. Took me 30mins to dismantle the turbo, then only took about 60mins to put it back together. We got it back in the car and its running great, no oil leaking into the intake manifold side anymore.

So all in all once you have the turbo off on any of these cars, its fairly easy to rebuild. So long as its a journal bearning based one, if its a ball bearing one, you wont be able to do it at home without some real speciality tools.
