Hey all,
Im writing from Sydney and I have done quite a bit of research over the last 12 months since the purchase of my 185 into the fundamentals of forced induction. I have read countless forums of people stating the same old thing (bigger turbo, FMIC, Custom EMS) and it just gets tired.
Dont get me wrong these are all ligitimate upgrades, but only depending on your goals.
Take the CT26 for example, love it or hate it, it is the beating heart of all but the newest shape gt-fours (alltracs) and yet people are so quick to rip it out or clip it, or put in a bigger trim compressor, or go through the above bracketed upgrades. This has always baffled me because I never see people posted that they run their cars at 16+ psi boost, which would be the only reason why you would need a bigger turbo.
Toyota did a brilliant job matching their ceramic turbine driven hairdryer to the rally bred, hard as nails 3S-GTE, because I personally have a turbo with atleast 50,000kms on it (just over 31000miles) and im getting 14psi strong right up to the redline.
Engine basics tell us that if your not increasing displacement with more cubes then you need to cram more air/fuel in under pressure. Hence, if your running a 2.0 litre 3S-GTE at 14psi boost with a CT26 it will make no difference than running a T04 turbo at 14psi boost.
My rather long winded point is that people believe that the CT26 will run out of air (actual volume of flowed compressed air) towards the redline at anymore than say 12psi boost, but I have found this to be un true.
Engines develop the most power from fuel when they are running to Stoichiometry. either side of about 14.7-1 air/fuel ratio you are losing power. So, the only way to increase power from a turbocharged motor is to increase displacement, or boost pressure, simple as that.
Upgrading your turbo is only really a feasible option if you intend to run 16+psi of boost on a balanced engine which would be revving beyond the stock redline. That is where, and only where a turbo with a higher flow rate would be required.
I write this to hopefully get many responses from people in this forum who have poured their blood sweat and tears into what i consider the best cars on the road, because I respect your knowledge and experience. Thans for reading!
