turbos has been around since the mid 70's and is every bit as old a design
as the k26. This isn't necessarily bad as there are some good combinations
of compressor and turbine available. Physical size isn't a good indication
either as I have some Mitsubishi turbos that are smaller, yet higher flowing
than the largest T3.

If you want the latest, look at the Garrett GT series. These are a couple
percent more efficient for a given flow and offer ball bearing center
sections. At the same time, if you weigh in price perhaps a few percent
efficiency isn't worth the additional cost... the trick is to make the most
of what you have with careful tuning and optimizing restrictions to flow
before bolting on the Gucci stuff. Airflow, not boost is what makes power.
Good engine management is crucial also.. ditch the CIS, it is evil.
