ct20b rebuild?

[MR2SIK]

Just out of interest, can a ct20b be rebuilt with better internals for more power the same way a ct26 routinely does?

Also, what would I expect to pay to get a ct20b rebuilt/refreshed to factory specs?


Cheers.

Ceramic CT20b rebuilt with a ST205 WRC steel wheel is about $800, i cant remember the exact figure. Thats with oversized bearings, new seals etc. Can find the receipt if your keen.

Was done by Alltech.

[MR2SIK]

Yeah, that would be great thanks,

so is that allow it to be more efficent/make more power, or just be more reliable in handling higher boost levels for longer?

Nah that was just back to standard. The steel wheel will allow more boost before shattering, but the ceramic ones do hold up pretty well. The oversized bearings were cos of wear and tear, standard size had too much play or something.

Ok, found the receipt.

Got oversized bearings because the standard ones were worn, and the compressor wheels came in contact with the housings.

It got: ST205 steel turbine wheel, bearings, piston rings, o-rings and got balanced. Total cost was $873.56

Cheers for that.

So does anyone know if the ct20b can be improved upon the same way the ct26 hybrids do? or is it a case of a ct26 being upgraded from factory and becoming a 'ct20b'

If you want more power, get a GT3071R

If my 180SX doesnt sell, ill put the T56 masterpower turbo onto my MR2 hahaha.

[MR2SIK]

yeah that was the plan lol, now moneys a bit tight, and want to go do things with my life so put the car up for sale, it decides to throw a hissy fit and i gotta fix a few things before I feel comfertable selling it to anyone I'd make a shit car salesman lol

[levinguy]

pm phothog on here, he knows all about turbos and can sort you out for a rebuild

I had to read your project page about 3 times to keep track of what turbo you're running lol.

out of interest, what are you doing with your ct20b now?

Haha yeah, i kept on changing my mind , ended up biting the bullet and putting the T3/T4 on. CT20b is in the garage, but im not planning on selling it sorry . Got plans for it eventually

So far there is no ct20b "upgrades" that I know of to make it better, because the CT20b actually has a smaller compressor housing than a CT26 AFAIK, there's not much room for you to put a better compressor wheel.

[Phothog]

The CT20b cant be upgraded as easy as the CT26,
because of the Bore where the compressor wheel runs.

the T04E Upgrade on the CT26 is fine because the compressor wheel bore is sligtly smaller than the CT26...

but the bore on the CT20B's is smaller than the T04E or even the GT2871 compressor wheels...

there is a way round it. but its a bit dodgy.

ct20b and ct26 have the same comp cover,and as chris says you can do upgrades
