turbo rebuild, help
 

so my turbo is blown (makes bad noise, and quite a bit of shaft play) and i was just wondering what was the best rebuild kit for the ct26. any suggestions? i dont really need anything new except for bearings, thrust collar, thrust bearing, thrust spacer, o rings, seal plate, shaft nuts and piston rings (compressor and exhaust side) right?

thank you in advance

oh and what are the best types of metals that these parts are made of?

Unless you've got the right equipment and experience to balance the rotating assembly this isn't something you can do yourself. That shaft and the attached wheels has to be very precisely balanced or it's going to destroy itself and potentially take the engine with it when it does. You're far better off sending it to someplace like Drift Motion.

how much would that be?? approximatelty?

thanks for the info

How much it's going to cost will depend on just how bad things really are inside... it's not something you can just guess at by feeling the assembled unit. If it is rebuildable it shouldn't cost more than $200... varies a bit by area though.

if i have to buy a new turbo because i cant rebuild this one, would you suggest getting a new stock ct26 or upgrading it to something different?
i ask because i have heard that the ct26 is an amazing turbo and has a very similar boost mapto that of what some larger turbos have.

If you're going to go with an upgraded CT26, I'd suggest a 57 trim. It's about the best compromise of power vs. reliability.

is it more or less reliable than the ct26

Probably a little less than the stock CT26, but still a pretty safe bet if it's done by a competent shop.

The 54 and 57 trim both get excellent reviews... quick spooling and a lot more airflow. The increase in rotational mass in the 57 versus the 54 is said to be negligible and as such the 57 trim upgrade is what most shops and owners recommend.

allot of people in the supra community look to driftmotion.com for there rebuild or upgrade. I would tend to check locally first.

For an upgrade I'd go with someone I know has done a LOT of them... for a rebuild, shop locally (I'd talk to truck shops (industrial) about who they use, not local tuner shops).

ok sounds good. im kinda on a budget and my friend owns a shop close to where i live and he just came to check it out. he says its just barely beyond the point of a rebuild. so, in that case, what is a good place to shop for an oem supra ct26 turbo? Is ebay a good place or are all those ones for like $385.00 peices of junk?

such as this one:
http://cgi.ebay.com/ebaymotors/Supra...Q5fAccessories

The new ones for $385 or whatever out of China are indeed pieces of junk you would want to stay away. Your best bet would be the "For Sale" forum here or on other Supra boards.

BTW, being "kinda on a budget" and owning a MkIII Supra aren't really compatible.

Personally, I'd still ship the old one to DriftMotion (or another turbo shop) to see what they can do... unless it's got so much play that it's been eating the compressor housing you really don't know until you actually disassemble it... but if you've got more than a couple millimeters of axial play at the end of the spindle, it is a good bet that it's shot. This is a specialized field and while a mechanic gets a good idea from past experience they still may be mistaken.

I agree about cheap turbos... they usually don't last and if they grenade they really do a ton of damage. I don't trust used turbos either (more accurately I don't trust the judgment of the sellers)... half the time you finally receive it and it's completely worthless or only has another 20,000 miles of life left in it (still rebuilding one is cheaper than a new, good turbo).

my turbo is completely shot, i believe, it deffinately sounds like it is scraping the crap out of the housing. so can you guys look around for me and try to find a good turbo. i need something in the range of 500 or less... preferably less. thank you all so much for your constant help with all my problems.

oh and this is a great line and ive really come to understand it now
"BTW, being "kinda on a budget" and owning a MkIII Supra aren't really compatible."

Well that does suck. I'll keep en eye out for you. If I think of any other solutions I'll let you know... are you worried about keeping the same power level? A CT-26 off a MR-2 may be easier to come by but it's not going to breathe as well at higher RPM.

as everyone knows, performance in supras is key :).
thank you i think i have found a few. i found a guy in arizona who has one and sent me a bunch of pictures. the car it came out of was bone stock and owned by his mother, who passed away a year or so ago. he sent me like 25 pictures of the car. it was in prestine condition and the car only had 39k miles on it. so im pretty convinced it is in good condition. should a ct26 have a tiny bit of axial play or should there be absolutely no shaft play?

thank you again for your help.

Most turbo's will have a small amount of radial play, even new ones depending on the type of bearings they use. Axial play is another matter, and you really don't want any at all.

Knock the kiddie crap off guys... I don't have the patience for it.

so one more question about the turbo. when i was changing out the turbo i lost a bolt. it is the upper bolt that bolts the turbo stay (bracket, brace) thing to the exhaust housing. I need to know what size that bolt is because i lost it and i have it ghetto rigged to work.

thank you in advance
