I have a 1994 S-10 Blazer 4.3L V6.Auto Trans. I am only 15.My grandma just gave it to me, she bought it new. Its in very good condition. I want to turn it in to a mudder. I have been working since i was 13 so i have a little money to spend about $2000. I just want to know where i should start. I work on a lot of trucks at my local auto-shop so the technical part shouldn't be hard. I just really want to know the right stuff to buy wisely with my money. Much help appreciated  

P.S its 4x4  

I also live near two truck junkyards so an axle swap is possible  

i wish i had 2 grand when i was a 15.  

A solid front axle swap and lockers is were I would start. IFS is weak and if you try to play in the mud to much you will be replacing parts all the time. and lockers I cant stress enough how much they will help.
I would get the axle under it first.
Good luck and tread lightly  

Lucky guy!look aat 4 wheel parts whole salers.com you can input the blazers info into the window,and it will tell you what parts fit it.luck to ya! i think if i had one i would stick a locker in back,put a little lift and agressive tires on the stock rims,and go play! or bush whacker co. has fender flairs that on some models,cut out and allow up to 3 inches clearance,that away you could spend more on the rims and mudders.I hope you have great times with the gift.one more thing,
4 wheel drive hardware has a jeep,catalog,i know,but they have factory dana 44's with lockers.they are 4 link ready.look around and see if ya get any ideas for axle swaps.happy wheelin!  

idk about performance, but you need to watch you ignitoin, starter, and fuel systems, because i got off roading in my truck, same one as yours, and i had to replace mine, a couple of times.

also, get a heavy duty air cleaner, if dirt gets in your engine, you can be screwed, all you need to do is just get some bolt on performance, raise it up a little bit, and get mudders on you wheels and you should be good, what kinda of mud you going in?  

and uhh, what do you have on it now?  

aight to start put a MSD ignition coil and distributor cap, Bosch 4+ plugs and wires, a K&N filter or K&N cold air intake, and a Optima battery then do your exterior and driveline mods i'd go with a 3" body or as stated b4 bush whacker fender flares and then some 33's on stock wheels and a rear locker but make sure to do those engine mods first they will help with your gas mileage and power and i know being 15 u prolly need all the gas mileage u can get and believe me it will pay for itself good luck and if u need anymore help holla
