In horsepower? Probably not as much as you would like.

In torque? Well... that's a different story. There's a reason I was considering doing this, but it would cost about twice as much as a top-of-the-line supercharger/turbocharger setup. Definitely not the best bang for your buck mod.

why would it cost that much more? granted, you'll have to disassemble pretty much the whole motor so you can get the cyls bored out, but you can order a set of pistons in nearly any size, deck height, dished, domed, ring variances, etc. your basic turbo/supercharger will run you around 5k for a kit.

I couldnt see the machine work and new pistons costing much more than that.

one thing to keep in mind tho is if you enlarge the pistons and bore the cyls, you will be changing the compression ratio, so you might want to get appropriate pistons to match.

the only thing that will cost the most is the time spent doing all of it.

but I could see the torque jumping a bit

Boring it to 4.0 wouldn't. Stroking it would. You would need a custom crank for that. And that starts to get really pricey, really fast.

so why not just bore it instead of stroke it? while it would be nice to have a "stroker", you could much more easily bore it out a little to get your 4.0L (or more depending on cyl wall tolerances) and get more torque and still be able to spin it up easier.

Dude you would be more than boreing out to get .4 Liters... you would be raping the cylinders and leaving tissues on the outsides to keep it all together.

Stroking is the only way to increase the size of the cylinders by 11%.

well, I dont know off hand what the bore is or the cyl wall thickness either. but if we need 25 additional ci..... without stroking......


it can be done.


bore to the max possible, run deep dished pistons with -25cc quad dishes and shorten the piston height down. you could get the needed ci. without stroking. but you wont be running nearly as high compression as stock.


but then again, why bother with stroking a v-6 for power. esp a DI one like this that would woop ass with a 100 shot o' juice

i havent heard much on DI with nitrous. but I would imagine that as long as the injectors and fuel pump can keep up. DI would be a perfect setup for nitrous. i'll have to do some looking on it....

Is it possible or doable to have a perfect sync with the injectors... N20 and Fuel

yes. its called direct port.

and thats what I was actually thinking of doing. only downside is it would require some dyno tuning running pig rich at first then leaning it back till everything is right.



now if you ran a fogger system in front of the maf, it would be the simplest setup. with a window switch.

call it a hunch I don't think the LLT can handle alot a pressure from a N2O system

The combined cooling effect of N20 AND Direct Injection could end up working in the engine's favor. But nobody's going to know till someone slaps a kit on these engines.

I hope they do... The challenger isn't a bad car, its just a bit too big for my tastes. And the competition is always a good thing.

And no, I'm not talking about weight - I'm speaking of dimensions. It is a large vehicle.

a fogger system is a type of nitrous that offers a more precise distribution of nitrous by having individual lines that go to each port in the intake manifold. Specially designed fogger nozzles atomize the fuel mixture very well so the fuel can be more easily burned.


I should have said a Dry system tho. a dry system is a nitrous system that feeds only nitrous through the intake manifold and not fuel. Fuel is added by the fuel injectors or secondary nozzles if equipped. it is also one of the cheapest setups to do.
