3S turbos & dump pipes

[Wildsupra]

Do the 165 185 & 205 all use the same CT26? I mean do they all use the same config CT26, i realise some of these motors came out with a CT20 and maybe other turbo's, but im only really asking bout the 26's.

Also would any custom dump pipe from a CT26 3S fit any of the 3S versions mentioned above or are the 3 versions different, thus meaning the same pipe couldnt be used on all 3?

Cheers

no the 165 and 185 use a ct26 but 185 is twin entryturbo, the st205 uses a ct20B.

[Jorrs]

also yes u can use dumpy of a 2nd gen 3sgte for a 1st gen, im just doing this at the moment.

[camrygt?]

the ct20 from 205 has an extra bolt hole or something on the dump flange but I have taken a ct20 dump pipe of a 205 and put it on a ct26 in a 185 with no problems there was an extra hole in the flange that wasn't used on the 185 so they are at least compatible that way.

Going the other way I presume there would be a bolt hole in the ct20 turbo but no hole in the flange for a ct26 built dump pipe

cheers guys.

Joors did you buy that pretty stainless one off oz celica??
Do you know if you can still get the replica's on ebay or wherever?

The shape of the flange where the stock "elbow" bolts to the turbo varies between a single entry turbo from a ST165 and a Twin-Entry turbo from an MR2. ( sorry, don't know M/Y of MR2. Cdn. spec though)

The twin entry turbo has a different shape/style wastegate valve, presumably to accomodate the twin entry and also I would suppose to reduce the chance of the housing cracking near the wastegate (common problem on ST 165 single entry type).
This different wastegate valve seems to be the reason the shape of the flange is different.

Also, the turbo is held at a different angle to the block on an ST165 and 185. (Ie., dump pipe would need to be a different length)

[Jorrs]

ummmmmmmm well i bought, fmic, piping, bov, wheels, dump pipe, so got the dumpy for 25 bucks.. i dont no of any others at moment though ? have u tried ebay ? i was just very lucky to grab it when i did, with rest of parts i wanted. if i see any other cheap ones going ill let u no though.

cool i'l check out Ebay,
Is OZ the brand??

Im not too fussed about quality at this stage, basically i just wanna get the car running, and need a dump pipe to do so, there aint no way im fitting the factory one

Isn't the CT20B just a myth thats made its way around the net? From what I understand its just a newer revision of the CT26, people have just assumed it a different model since it doesn't actualy have a model number on it as the previous versions did.
