Just found this FYI.
"If you are continuing to identify the turbo of a 3SGTE 3RD Generation as a Toyota CT20 or CT20B then you are referring to an imaginary, non-existent turbo. This turbo exists only in the Internet. There is NO Official Toyota reference to this turbo in any Toyota Manual, CD Rom, or sales literature- that we have seen, that uses this designation to identify the turbo as installed on the 3SGTE 3rd Generation engines. There is a REAL Toyota CT20 turbo used on the 3TGTE, 4TGTE, and 22RTE engines in the 80’s but this will not bolt on the 3SGTE manifolds.
We have imported and sold many of ALL these engines types. We have ordered and sold many replacement turbos for the 3SGTE 3rd Generation. There is no casting designation identifying these turbos as CT20 or CT20 B. Many shops and individuals continue to sell and modify this turbo without knowing what they are handling. We have given this information to all inquiries for this particular turbo.
There have been many 3SGTE Celica and MR2 owners who have been misled into buying the real CT20 turbo from the older turbo engines. The seller is 100% correct in selling them as such with the casting # to prove so. Shops and individuals who pass the CT20 as upgrade for the 3SGTE- do not know any better. The buyer must be made aware that if they want the real 3SGTE 3RD Generation Turbo- it is not the CT20 or 20B. NO, we have not sold any of the CT20 / 20B as upgrade or update for the 3SGTE engines, despite insistence from many to purchase a CT20 /20B based on misinformation from the internet. In some Toyota literature these 3SGTE 3rd Generation turbos are still referred to as the CT26.
There are actually 2 different 3SGTE 3RD Generation Turbos- #1 as installed in the 1994 - up Celica ST205 and MR2 SW20 vehicles the flange is similar to the CT26 but with a Twin Entry casting and Ceramic impellers; #2 as installed in the Caldina ST215 (and other ST2XX models) including the newest 2004 model Caldina ST246- the turbo center section housing is cast in one piece with the exhaust manifold, also with Ceramic impellers. Again there is no identifying models on this turbo.
Also- the racing “3SGTE” based Toyota racing engines are not 3SGTEs- they are known internally at Toyota as 503- as used in IMSA, Pikes Peak, HKS drag car, and Le Mans. No internal or external parts are interchangeable.
To prevent another controversy and correct widespread misinformation- the Caldina ST 215 (and other ST2XX models) 3SGTE should not and cannot be referred to as 3SGTE 4th Generation . The 4th Generation head supports the VVTi valve set-up and has direct ignition. The block is identical to the 3rd Generation. There is a REAL 4th Generation 3SGE but they were not available with turbo.
Hopefully this will clarify the Turbo identification and the engine designation problems of the 3rd Generation 3SGTE."
