How would a 603 with a VNT compare to a GM 6.3 in a Tahoe/Suburban sized vehicle?

I'm just daydreaming, I can't even afford a gasser Tahoe

The 3L stock puts out about as much horsepower as the 6.2L in the tahoe. For just driving, it would be ok. I don't know about the other complexities of installing the engine.

The 6.2L has an extra 50lb/ft of torque. For a driver, it wouldn't be much different than having a g@sser instead, just a bit slower.

For any kind of towing, stick with the 6.2 or find a 6.5t.

the horsepower might be about the same cause i think the 6.2 is about 180hp but the V8 is going to produce a lot more torque. I've been thinkin about a 617 in a 4 wheel drive S10.

The 6.5T has in general been a terrible engine. It's kinda the GM version of the 603 3.5 liter.

Thats not in the least bit true.

The 6.5 was designed from the start to be turbocharged and, although it's design is a little funky, its a good engine that can support around 300hp with marine components. It wouldn't be used in one of the most successful military vehicles (Hummer) if it wasn't good.

that is the exact same thing i tell people. i dont see H1s with a 12/24 valve cummins or a 7.3 powerstroke. The 6.5 got a bad rep in the early 90s when the injector pumps failed but GM replaced them with the newer version used on late model 95s and newer.

The civilian H1 is a troublesome beast, I've had one. The reason that the GM diesel was used is that it is a simple throw-away engine, the military drops in a new one when it wears out, had to be a diesel, ... military bidding system and all, ... often the lowest bid wins and once you're in, ... you're in.

6.2 was definately not 180 hp. It was 130 if I recall. The latest 6.5 turbo was 215

Gotta love how people with NO experience with a 6.5 think they are crap. I've got one with 250K, trouble free, though it does need injectors right now. If you believed all the BS dimwits post on every diesel forum you wouldn't buy anything. RT

Hmmm. Didn't know they made a stock turbo engine (go on, laugh at me)
Sounds like sticking with a GM engine would save alot of headaches

i have never had a problem with a 6.5 and i strongly prefer the V8 powerband over that of a 5.9 cummins. the best thing to do with i 6.5 is lower the compression ratio and throw in more boost...this is all excluding the fact that nothing beats a chevrolet in handling. trying to keep a straight axle dodge or ford on the road is not pleasant.
