Bringing on the Action ;)

Okay Boys & Girls,

This is the story.

A mate of mine has a couple of CT 12 turbo's, off a Toyota Soarer I believe, lying about and the plan is to turbocharge his and my minis. Now mine is a standard A+ high compression motor (flat top pistons) which according to my calculations, with a standard 295 head bolted on will have around 8.95:1 CR. The idea is for a low boost, low cost solution. First plan of attack is to fix the 295 with a home made manifold and turbo with really low boost to see what the car goes like. If we like what we see, we will work on making things a bit prettier I do understand the static CR is a bit on the high side. However, from my understanding, the CT 12 will take a while to spool up so i doubt I'll ever achieve max boost if I limit my revs to 6000 RPM.

Thoughts people? I'm by no means a turbo expert, not an expert at anything really I'm happy to listen to your suggestions and see where we go with this plan.

Cheers

Iv had a little search but cant really find much information on the ct12. If was off a soarer it would be the 1991-1996 which is the 1JZ-GTE (2.5 L I6). These are a ct12a twin turbo.

CT12A Turbocharger Specifications (1JZ)

Manufacturer : Toyota (Hitachi)
Type CT-12A (Part Number : 17201-46010 (Front), 17208-46010 (Rear))

Turbine size (Outlet diameter) 42mm
Turbine size (Inlet diameter) 51.6mm
Turbine Blade count 8
Turbine Material Ceramic
Turbine Housing Outlet (ID) 44.1mm
Turbine Housing Inlet (ID) 33mm
Turbine Shaft Diameter 8.5mm
Turbine housing A/R .45

Compressor size (Inlet diameter) 35mm
Compressor size (Outlet diameter) 54mm
Compressor Blade count 10
Compressor material Aluminium
Compressor Housing Inlet (ID) 37.9mm
Compressor Housing Outlet (ID) 30mm
Compressor housing A/R .30

Bearing ID 8.53mm
Bearing OD 13.55mm
Bearing Width 9mm
Bearing material Bronze
Bearing oiling holes (per bearing) 6

*Wastegate size (ID) 20mm
Actuator spring rate 10 psi


so comparing to a stock T2 which works well on 998-1275 it is slightly bigger but still smaller than a t25. But as the turbine is only a .45AR spool still should be fairly quick , but will give some awsome top end.

Compressor :
inducer 34mm
exducer 48mm

Turbine :
exducer 35.5mm (11 blade ceramic)
inducer 47.5mm ish

Id say give it a go if it pysically fits:)

Woohoo action!

Good that you and your mate can split a couple of turbz haha

Looking forward to the build thread

Yah! Action!
