Other than the obvious configuration difference, what is it about an inline 6 that makes it different from a V-6? They're seem to work very well in the Z, why aren't they used in more cars?

Cost.
A V-6 has a shorter crank so it doesn't have to be as beefy. The engine compartment can be shorter. The hood can be lower. The intake runners are shorter and easier to tune. The list goes on.

there's also a production cost savings. a v-6 can share components with a v-8 from the same manufacturer. they can use the same pistons, rods, valves, other valvtrain components, bearings, distributor parts, on and on and on. the only difference is two cylinders. a lot of manufacturers can build a v-6 on the same assembly line as a v-8, or at least with a very similar setup. being able to share components cuts production costs and lowers retail prices. this is why mercedes-benz switched over to v-6's last year.

On that note though, a straight 6 can share parts with a 4 cylinder which is something nissan is more likely to manufacture than a v-8 (aside from the infinity one of course) but in terms of packaging a v-6 can be alot more compact overall, plus it's alot easier to use a v-6 in a front wheel drive car (can't think of any I-6 front wheel drive cars) and since every **** car manufacturer has pretty much switched to front drive on almost all their vehicles. It saves them money on having 1 basic powerplant for all vehicles. (kinda like the reason they make em all front wheel drive in the first place: Lower cost of manufacturing even though it has the side benefits of being safer in bad weather)

Ok speed Diffents between the two

Ok easy one for everyone besides easyer makes or the v6 and v8s. What is the power diffetns between the two inline 6 and v6 I would think the inline 6 is better but now as time gose on smaller motor are gettting stronger then some of the big ones

the better balanced motor should have more power potential. according to the Bosch Automotive Handbook, a portion of it reprinted in the Oct issue of Road & Track magazine anyway, there are only three perfectly balanced configurations: inline 6, flat 6, and 60-degree v-12. Datsun (along with Mercedes and Jaguar), Porsche, and Ferrari all got it right from the start!!!
