The CT12 Turbo's have the ceramic turbine wheel which is very brittle and doesn't handle high stresses. The CT12 turbo is also restrictive and responds well to high flowing.
Like all toyota designed turbo's they are very well made and have good reliability as a stock unit. The week ceramic turbine is the only part which can give problems but it has been designed with response and only factory power levels in mind. Options below can be built as an exchange or the owners turbo's.

Fully overhauled including kit (new o-rings,
seal,bearings)
STEEL turbine wheel
Fully cleaned and dressed to appear "as new"

testing.
BASIC High Flow..............$2400
Exchange can be ordered or owners turbo built.(No outright purchase)
includes:-
Fully overhauled(as above)
47mm BILLETcompressor wheel .
Steel turbine wheel of a custom profile for better flow but not sacrificing spool
more efficient.
Stock adjustable Actuators
High Flow with ported Housings.............................$3450
Extreme Ported Manifolds.................. $1100
Exchange can be ordered or owners turbo built. (No outright purchase)
The highest restriction of the 1jzgte twin CT 12a turbo system (besides the intakes) is the tiny exhaust Housngs and exhaust Manifolds. The manifold ports are tiny and smaller than the average male finger size. Using special tools and experience, with many hours of labour, they are extensively ported, and along with the specially made highflow Turbine wheels and Large Billet Compressor wheels, they have poven results over 550rwhp with a oem stock look.
Includes:-
-Fully overhauled(as above)
-47mm BILLET compressor wheel .
-Steel turbine wheel of a custom profile and larger exducer.
-Ported turbine housing for much better flow and improved spool up- more efficient.
-Ported wastegate hole and unshrouded
side walls
-Heavy Duty Wastegate actuators set at a higher base pressure
-Ported wastegate hole and unshrouded.
- Ported compresor housing to raise the AR size
-Optional extra - Ported manifold for much better flow at higher revs.
Rated 300rwkw + with stock appearance using Big intakes and dumps.
High Flow with ported and CT20 CHRA.............................$4250
Manifolds.................. $1100
Exchange can be ordered or owners turbo built.(No outright purchase)
Above the previous level upgrade the CT12a center cores are replace with very heavy duty CT20 cores, compressor wheels and turbine wheels. These are built as a heavy duty high flow upgrade capable of exeeding the previous CT12a high flow HP. The CT20 cores are bullet proof if all the system is setup correctly and can out flow any CT12a product on the market. Still with the extensive porting as the previous high flow yet a lot tougher, flowing more and at the limit these can flow. Stock CT12a shaft is 8mm x 5.7mm. CT20 Shaft is 10mm x 6.5mm, meaning they are very durable. Reports of well over 550hp with supporting mods being very conservative.
Includes:-
-Fully overhauled (as above)
-Full CT20 chra that features and much stronger shaft and other heavy duty components, including 360 thust, special oil seal and drain.
-Supports huge loads and HP.
-48mm BILLET compressor wheel .
-Steel 48mm ct20 turbine wheel of a custom profile.
- 360 Degree thrust for handling extreme boost
Extreme.
-Anti Surge ports machined to Compressor housing
-Ported compressor housing to raise the AR size
-Ported turbine housing for much better flow
-Ported wastegate hole and unshrouded side walls.
-Also optional ectra-Ported manifolds for much better flow at higher revs.
Rated 340rwkw+ with stock appearance with Big intakes and Dump pipes.
