Discussion and technical advice the SW20 MR2. 3S-GTE, 3S-GE, 3S-FE etc
Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
After having the car for just under a year i have only now seen that my rev 3 has a CT26 turbo and not a CT20B ( see pic )
The car was sold as having a stage 2 turbo with cut back exhaust blades and 360 deg thrust bearings and i have a invoice from www.crturbos.co.uk for £ 550 but no description .
The car was on the rollers in Feb and made 290 BHP at 0.9 bar ( see pic )
I thought that the CT26 did not flow as well and ran out of puff hi up the rev range and that the C20B was better but on my graph this does not seem so as power is right up untill 6600 rpm ?
I take it that this hybrid CT26 can flow more air and this is the reason for the hi ish BHP on stock 0.9 bar boost .
Thoughts on this would be great
Regards
Alan

a hybrid is that, a hybrid, it has been made to flow more than stock
even more so than a CT20 apparently, is the CT26 not the larger of the 2?? albeit doesn't flow as well. Hybrid is a completely different animal so I've read.
Ah ok this would Explain it as i thought he would have used a CT20B that would have been on the car .
So the CT26 is a larger unit than the CT20B but does not flow as well in std form then ?

Just found this that would Explain it . It would also confirm that i have a hybrid turbo
The CT26 is the turbo to build a hybrid from not a CT20B. It has a larger turbine wheel and the shaft is bigger, the CT20b shafts snap.

Yarp them's is ceramic. can't rebuild them without snapping the shaft and replacing it with a steel one. Its the balancing the busts the shaft.
So you really have to use the CT26 if you go hybrid .

No you don't.. if you swap the shaft for a metal one you can hybrid it. but the CT26 is just a better base.

Got the CT20b steel shafts in stock for any rebuilds needed.
