Just bought an 02 Blazer LS, 4.3L V6 of course. I just want to see if you guys had any ideas about what I should maybe do to it? Just got an Optima battery, bosch plat +2 spark plugs, accel performance ignition coil, yellow plug wires, and did a pretty standard tune-up. Im not gonna drop/lift it at all, but I am gonna throw a body kit on eventually. What about tires/exhaust/air intake? Any ideas for the interior as well?

 

work on clearing up your exhaust stream, blazers have two cats and a large muffler. and obviously cold air intake and a throttle body spacer help with response. start there then after all that get a good tune to your pcm and you should be set.

 

Late model Blazers like your's and mine have a small pre-cat heater to help the cat get hot, but it's not actually a catalytic converter. They do have a water-heater-size factory muffler, though.

 

well start with a cold air intake, then maybe a thrush muffler, custom tune
maybe the marine intake, theres a write up on here somewhere
if i can find it ill post it

 

thank God the ealier ones don't have it (just another expense i'd have). as for the "water-heater-size factory muffler", it just stands up to more off-road abuse!
i just found that out this weekend, after i found chunks of mud 'n grass jammed in everywhere under (& back) there. my trailer hitch looked like a damn Chia Pet.
anybody know how we're supposed to flush out our frames. i liked the 1st gen's with their open frames, much easier to scoop out the mud.
