Hey there.
The compressor wheel of a TC05-12A-6cm2 has an inducer of approximately
40mm, the exducer is approximately 54mm.
The compressor wheel of a TC06-11A-8cm2 has an inducer of approximately
40m and an exducer of approximately 65mm.
The turbine housing of a TC05-12A-6cm2 has an exducer bore of about 49mm.
The turbine housing of a TC06-11a-8cm2 has an exducer bore of about 58mm.
On Australian Cordias(1.8 litre), those fitted with a TC06 make 110kw(147hp) @ 6000rpm. Â
Those fitted with a TC05 make 90kw(120hp) @ 5500 rpm.
I would be interested to know how the specs of your TC05-12A-8cm2 as fitted
to your 2.6 starions compare with the TC05-12A-6cm2 as fitted to our Cordias
and Starions.
