6.5 Diesel

The most under rated diesel engine. It's a redesigned (BY GM NOT DETROIT!!!) 6.2 GM engine. Factory rated at 180 HP, most people think it's a pile. The PMD tends to fail in the 94+ electronic fuel pumps. However with a few mods it can be made very reliable and even put out some decent power. Its trash talked but some people have made it put out well over 300 HP on built motors which isn't bad for a truck that can be picked up for under 5 grand. It gets decent milage too, and they are very nice trucks.

Dude that truck is sweet but the 6.5 Diesel is a pile.
*truck starts*
Hey, that doesn't sound half bad
*Truck peels out and takes off with a huge huge smoke cloud*
Dude, was that really a 6.5?!
HELL YEA! PWNED!

6.5 Turbo diesel

An engine that is the literal honeybadger of all diesel engines. It gives no shits on what fuel it runs on, what kind of oil is in it (if there is) or how much boost is being shoved into it. This engine is one of the most controversial and hated engine in the diesel community. Much like the 7.3 its so fucking slow that everything could beat it in a race. Like most Detroit Diesels, it runs shitty, but forever.

That must be a 6.5 Turbo diesel, it hasnt died yet!
