These little trucks seem to be wide open to modifying. Normally, you'd want a small turbo close the engine on a small displacement vehicle so you wouldn't have turbo lag. That presents packaging problems. A remote mount turbo system give you much more leeway as far as packaging, but at the cost of lag. But, who cares about lag when you're doing it to increase top speed instead of acceleration? Most remote mount turbo setups get rid of the muffler, so backpressure downstream of the turbine is eliminated. The turbo acts as the muffler.
