What problems are they having with that engine? And where did you find a weight for it? Just wondering. This next summer I am going to be looking into getting a new truck, and the Colorado is on my list, although I'll probably go full-size.
Well, its an iron block according to the brochure, where as the LS1 is aluminum......I should've said I wouldn't doubt the engine.....cause I don't know for sure....
and problems, well, piston knock already, and electrical gremlins are what I've talked to a couple salesguys about. One person ordered one, and en route from another dealer it just shut off.....its in their service bay right now trying to get fixed, but they can't find out whats wrong with it. I'm sure there are going to be more problems, there always are the first few years of production.
Lost foam casting
The foundations of Colorado's engines are deep skirt, CAST ALUMINUM engine blocks. They are produced with a lost foam process that allows more precise dimensional control, while reducing necessary finish machining in oil galleries, coolant passages and other internal passages. The deep-skirt design places block material below the crankshaft centerline to enhance rigidity of the block, while the lightweight aluminum offers better control of oil temperature, eliminating the need for an auxiliary oil cooler. The lighter-weight engine block enhances fuel economy, too, by reducing the overall mass of the vehicle.
The Vortec 3500 and 2800 employ a lighter weight all-aluminum cylinder block and a deep skirt design for structural rigidity. Finite element analysis (FEA) was used to optimally balance and reduce block weight and enhance rigidity for smoother, quieter engine operation.
clearly, these new engines are way better then the vortec 2200, these are bigger, lighter, stronger, and flow more air in and out. They have higher compression ratio, better ignition, and they have vvt (variable valve timing) something that our 2.2 engines will never see. Yes, I know I drive one, but not for long.
well make it happen move the rad forward get a smaller ac condensor get some damn good small fans pound away at the fire wall hope the motor mounts will match up in a close area of where it will sit and find a wiring diagram and go to town with the first s-10 5 cylinder.
