Just wanted to share this: turbo 1NZFE

Found this, a turbo 1NZFE. The car is a Thai Vios, a Southeast Asia market-only car. It has basically the same internals as the old Echo. Here's an excerpt:

Now we come to the juicy bits. The 1.5 16 valve DOHC VVT-i 1NZ-FE engine has been turbocharged with light boost pressure as the compression ratio of the engine is still quite high for a turbo-ed engine at 10.5:1. Normal for a bolt-on setup. The ECU has been upgraded to detect boost and adjust air-fuel appropriately.

This results in 143 horsepower at 6400rpm and 196Nm of torque at 4400rpm. The gearbox is a 5-speed close ratio gearbox for maximum acceleration. This takes the car from 0-100km/h in 8.1 seconds. The car does the 400meter sprint at 15.9 seconds.

I suppose if you can lower the compression to something like 9:1 you could boost it up higher and get even better performance out of it.
