Lol!!! Pug is sold all over the world and is famous in hot harsh desert Iran as the locals there luxury dream cars. Even if the Pug doesn't last long, it is still using a globally recognised engine & gearbox.

As for TS:
Preve/Suprima Turbo, the engine design is taken by modifying old MMC 4G92 engine. When MMC merged with Chrysler and wanted to heal its ruined reputation, they took back almost everything from P1. That was when the S4 Campo engine was made after 4G15 is banned from Wajunk. Its turbocharger is obsolete wastegate type turbo that most brands no longer use them due to lag and prone to carbon buildup. Preve/Suprima turbo could only start spinning from 2000rpm or higher, depends on gas pressure. On certain sudden deceleration and needs to accelerate again, the gas pressure might need much higher RPM to spin turbine.

FC wise, refinement and proper turbo go to Pug's Prince THP engine. Want to go for car with turbo, make sure it is Variable Geometry Turbocharger or Twin-scroll Turbocharger that could operate from lower RPM as in Pug THP at 1400rpm with no more lag. Check with Pug owners especially newer batch on maintenance. The earlier Pugs, there have been incompatible issue with our hot & humid climate. The new ones, if they are willing to check our weather and come up with proper parts that could withstand our heat, they should be ok. Can't help you on this as my tech buddies have left Pug technical few years ago.
