Re: Iron duke vs 2.2

With reasonable care either engine will last beyond 200,000 miles.

The 2.2 is smoother, quieter, and a bit more fun to drive ( revs past 4000 rpm , woot ) than the iron duke with a empy or lightly loaded truck.

With a heavy load the iron duke will out pull a 2.2 , not that it has more power or anything it just has a more torque in the low and midrange revs where you need it.

Not that either one is a real powerhouse.

Re: Iron duke vs 2.2

I own both and each has their pros and cons. I do believe that each will surely outlast 200,000 with proper maintenance. I have only owned my 2.5 for a few months so I can't really talk much on that engines behalf, other than parts being inexpensive and the engine bay is not as crowded as a 2.2. I have had my 2.2 for 3 years and am very pleased with the little engine. I have done countless head jobs at work(thanks to cast aluminum on cast iron) and have found the engine a fairly simple design to work on. I am very happy with fuel economy, more so with the 2.2, although the 2.5 does well also. I have also found the 2.2 with obdII to be much easier to diagnose problems with as apposed to the 2.5. Both will take care of you, if you take care of them.

2.5l is not hard to troubleshoot either, if ya know how to diagnose one....

Member Willie got 1.3 Million miles on his duke before a rebuild with no major issues before......

I'll admit that I don't have the most experience or knowledge with obd1 vehicles. So far I have had to do a lot more with my DVOM then I ever have with any obdII vehicle.

Yeah, does require some meter usage, but they can be easy to work on....

Re: Iron duke vs 2.2

I beat the snot out of my 2.2. Got almost a whole season of racin with it turning 7 grand going into the turns... and that was with 200,000 miles on the little guy. The key is keeping the alum head cool. Going to try the duke this season.

Re: Iron duke vs 2.2

Funny thing, I live in Skaneateles. I have 6 Dimes, and maybe would build one for the hell of it. Where do you guys race? Weedsport? Brewerton? Dundee? Rolling Wheels?
I used to race enduro, but haven't had much time. I may be taking some time off and will possibly get a chance to race again.
Most of the time, I've been drag racing.
Sorry, didn't mean to jack.

s10masterman... It was not my intention to jack either, sorry.

Mad Max, What a small world we live in. I'm just over in Lafayette. We race in Cortland at Skyline Raceway. We're always looking for new guys to join. I'll send you a PM.
