LSX376 B15 W/TWINS 2002 silverado 4X4
I BOUGHT THIS never run NEW MOTOR FROM A GUY GETTING A DEVORCE...FOR LESS THAN 1/2 PRICE.
So what turbos should I run 2-VS78/75? - 2002 Silverado 4X4 with 4l80e
looking to run 25-30#s of boost
65% street and some drag racing
I don't have any power goals, just going to accept what I get out of the motor with up to 30#s.
will run 15# most of the time and up to 30# at the track.
just a fun fast truck.

Do you come from imports by chance? 30lbs is a toooooon of boost in an LS. Hell, most trucks can't hook with 10-12lbs
either way, can't help you with the turbo size, just wanted to pop in and say you're gonna need a helluva fuel system, trans and rear ending to hold that thing at 30lbs, if you get there. Be ready to drop 10-15k on running and suspension gear to couple that power to the road

Yes 30#s is a lot of boost
a lot of the LS magazines have run this motor up that high but not with twins. ( that I can find )
I have almost all the supporting chassis & Fuel stuff needed . still adding a few as I learn.
