question is what would be best forged 6.0 lq4 with boost or 402 with nitrous ? i any can help please let me know ?

 

nitrous will be cheaper, much cheaper. either way you go you will need lots of supporting mods, whats done to the truck now?

 

Nitrous in general, ya. Toss a 4" crankshaft into the math and the turbo setup will cost the same as stroker + nitrous.

I'll answer the above question with my favorite bumper sticker; "NOS is nice but I'd rather be blown."

 

turbo 408 with nitrous -- have the best of both worlds

It depends on what you want... There is no "best" here, just "best for your wants".

There's a comparo thread over in FI that might be a great place to start.

My personal preference is this:
n2o = a lot of fun, more expense in the long run (think of all the bottles), plus only there when the bottle is "conditioned"
turbo = a lot more fun, always there, a bigger front end expense and a lot more work -- most power comes from turbo, then blower, then N2O.

So the question is: what do you want from the combo? You'll get more meaningful replies if you post over in FI with that information, IMO.
