Hey i have a 2002 blazer Ls 2 Door and i would like to know what is the best
Exhaust?
Air Intake or Super Charger or both?
Chips?
Anything Else

Thanks Man Appreciate it

 

Since nobody else answered, I'll give my .02. If you're going to do anything besides an intake, exhaust, and tune, just swap in a 350. It'll be cheaper. I just bought the dynomax exhaust from Summit, with the $75 rebate, makes it $62 shippped. Not too loud, but I def. noticed a lot more power. For the $$, I don't think you can get a better exhaust. Have to order it today to get the rebate though. As far as intake, the Spectre is def. the cheapest. I doubt that it REALLY makes that much difference which brand. Just get some cold air to the engine. Supercharger? No way. Too expensive. WAY too expensive. Haven't done anything with a tune yet, but I was thinking about getting a pcm4less tune. From what I've read, it really makes a difference, and is the best power/$ mod you can do. Good luck!

 

Exhaust, gears and tune. Beyond that everything is too expensive because the 4.3 isn't that popular to mod, everyone likes small blocks. For a tune, BlackBear Performance does awesome PCM tunes.

 

us 2 dr guys don't have it that easy

 

Cherry bomb muffler from Meijer $20, and $60 at a muffler shop.

 

What size gears?

 

Stick with the basics ... kind of do it in stages so stage 1 for instance would be the obvious upgrades such as headers, intake and exhaust stage 2 would be cam, head work, etc etc that is how I would do it I prefer imo the N/A 4.3 they are just awesome motors I am not sure how many miles are on mine but I am sure 250k + and it is still running very strong odometer still reads 176,050 lol
