Duramax v powerstroke

I have a 7.3 and I'm gonna keep it, just wondering if anyone knew about duramax, Thinking of buying an 2001 duramax has ppe hot 2 intake exhaust, 200k miles, said injectors were replaced at 150k, has zf6 manual tranny. That's the tranny I want. For 11k. Is it worth it? How long will the injectors last and how long will the engine last?
I'm to lazy to make a duramax forum account

Don't know why you'd want the manual tranny, the Allison is a great transmisson, better when built.

The engine is reliable, the injectors are not. The earlier Dmax's had the biggest amount of injector trouble and they are expensive to replace. Some last 100k miles, some last 40k miles.

Other than that, my experience is that they eat front end parts, have electrical issues galore, and rot pretty quick.

I would say not worth it either. '01 is the first year and alot of bugs. Fwiw, all GM vehicles have terrible electrical issues especially ones with alot of bells and whistles.

[QUOTE=bikeluver43;6668185]Don't know why you'd want the manual tranny, the Allison is a great transmisson, better when built./QUOTE]

I 100% disagree, I've seen 4R100 transmissions last longer than Allison transmissions. A 4R100 can handle about 100-120 hp over stock. I have yet to see a Allison trans hold up to 80-100 hp over stock. Just because Allison makes tanks transmissions doesn't mean they are tough!

Bloom7.3, I woudnlt drive a Duramax simply because I don't like the IFS. But sounds like you can pick that truck up pretty cheap. Plan on putting a clutch in it if... Unless it already got one.

I don't recall comparing the Allison to the 4R100, nor do I understand why people feel the need to jump on the Allison bashing bandwagon - yes I get it, its not the allison from an 18 wheeler/tank nor is it indestructable - and I never said it was.

BUT, it has great gear ratio's, its very easy to rebuild, once built (just like a 4R100) its nearly bulletproof but has 5 gears rather than 4 (6 on the later years) and the spacing on those gears are excellent. THAT was my point, it is a very nice automatic transmission - yes add some power over stock and it goes into limp mode, but my point was simply it's a better option than a 6 speed behind the Dmax.

Umm... I didn't say you compared it to the 4R100 but I did. That's my opinion... My opinion is also that if you plan on going above the stock power levels of the Duramax and you have an automatic trans... Be ready to sink $4-5k to make it built proof. I also would prefer the manual trans over an Allison... Anyday!

the allison 500 (the first one) has to be upgraded to handle 50hp or more over stock. the allison 1000 is the beast.
