I just got this 2001 Chevy Suburban and im looking to make it into a sleeper does anyone know what is the best bang for my buck in the performance department for this car.

 

Welcome to the forum.

Try Blackbear performance. Stay away from add-ons unless your talking superchargers.

 

Small increase and better throttle response: pcm tune, cat-back exhaust

Medium increase: camshaft swap, might need to tweak the transmission to handle the extra power.

Large increase: Bolt-on supercharger kit, but you'll have to beef up the transmission and rear end.

 

Where could i find the parts to do a camshaft swap and how much horsepower would i be looking at with a camshaft swap

Read up on the GM Engines themselves. The 5.3 accepts the 6.0 intake and maybe a few other parts. You can mix and match parts to get a fire breathing 5.3.

 

Speaking from more marine experience where reliability is king over HP... ever try to call a tow boat...?

I wouldn't mess with it... it's already 13 years old! if you want more power, buy a newer one or a sports car...

I've seen many, many cases where adding power to already long lived engines causes engine failure within 1-2 years...

It's your truck and your money, I just don't want you to bolt on more HP after $$$ and then lose an engine... that's no fun...

 

I forgot nitrous.

One other thing about adding more power even if you don't blow the engine as Sst suggests is that you will most likely find the next weak link in the rest of the power train like tranny, u-joints, differential, etc.

 

Did you guys read about what happens when people bolted on more power to the V6 mustangs that were already 300HP?

they were blowing drive shafts at 120 MPH.

the V8 mustang drive shaft was a different part # than the V6 one... I believe a strong one.

I agree, that if the engine doesn't give up... your transmission, drive shafts, u-joints, etc. might.

Also, with great power comes great responsibility.... as in bigger brakes.
