Are there any mods for a 05 trailblazer with the 5.3 Engine?
I would assume it is the same as the silverado/etc.... But you know what happens when you assume .. LOL

 

Nobody on here has a trailblazer? They are the same frame/chassis/engine setup as the SSR so anything that works on the 5.3 ssr should work on the trailblazer..
I'm just curious to get even more power out of this thing and I'm new to the community so any help would be appreciated.

 

Yeah anything mods that are out there for the 5.3 should apply to the TB's also. Start by getting a good tune go to nelsonperformance.com. He is highly recommended. BUt you can also get a hand held programmer.

 

when did the trialblazers get a 5.3? i thought they had an inline 6...

edit: ok i just found the EXT trailblazer. now i know

 

As long as they are not body specific (CAI, headers, catbacks, etc) any mods for the 5.3 trucks should work on your TB.
