5.3 performance mods?


Recommended Posts

I'm pretty sold on doing the upgrade whenever my transmission needs a rebuild. A couple shops offer a kit that essentially turns your 6L80 into a 6L90.

 

Considering the 6.2 uses the same 6L80 as our 5.3 I'm not as concerned about it handling a few power addons.

armaggeddon turbo systems is laying down 600 hp on all stock 5.3s forget how many thousand miles they ran but zero issues and they gtr boost launched that thing constantly....youtube them

Honestly I'd pay 6k and get a supercharger.

 

They only time it'd be worth that 10 grand is if u had a built engine and Trans and could use the up to 1500 hp that that kit is capable of.

 

Was just pointing out that these engines and Trans are stout and are holding over 600 all stock
