I have a 2000 4wd Blazer. I want Nitrous Oxide. I just want to know if it's okay to use on a 4wd vehicle or not. What are your thoughts? If it's not a good idea, I am thinking of buying a 2004ish Xtreme to put a turbo and NOS in, and giving my 2000 Blazer to my younger brother.

 

You can use it on anything you want.

 

How about my lawn mower?

 

It's been done before... As well as turbo lawn mowers... Mower races are funny to watch, lol

 

I mean are the 4wd gears in the rear differential too sensitive to install nos?

 

They're the same gears as the 2wd version...

With the exception of the ZR2, which, if I remember right, gets a beefier rear end...

 

i ran a 100shot on my bone stock 2wd 2door blazer for a WHILE!..... if you have 4wd you should have an 8.5" 10-bolt which is stronger then a 7.5" 10-bolt. it should be fine.

 

Only the ZR2's got the 8.5" rear end, all other Blazers have the 7 5/8"
Both are 10 bolt.

 

You'll be fine. A 100 shot would only get you tow 290 fly wheel hp, which is not much. My buddies usually didnt break their stock 10 bolts in ther F-bodies until they got to about 400 rwhp. Although who knows you could break stuff, anytime you start adding hp there are eno gaurantees.

 

not to hijack your thread, but how do you plan on bumping the timing back and richening the mixture?
