| Turbo Comparisson | ||
| In an attempt to answer the question “ what’s the difference?,” I have put together a chart (see below) of the diffeences between the models. Keeping in mind the differences between the T1,2,3 & 4 engines, some of the turbocharger components changed accordingly. With most things, bigger is better, as that is true with turbochargers when you are looking for maximum potential. If faster spool, and low-end power is desired, then the smaller turbo’s can actually offer an advantage. Chrysler’s Turbo motors were an evolution in design, including both one of the first sucessful Multi Port Fuel Injected Turbo setups and one of the most powerful 4 cylinder engines ever sold in the USA. |
