I have a 93 s10 blazer and a complete syty 4.3 that needs redone. Do you guys think I should do, buy a 5.3 vortex and make it a LS1 or redo the 4.3 turbo. Right now the blazer has a CPI 4.3, auto and its 2wd.

What do you want to do, more importantly how is your bank account? If money isn't a issue.....swap the LS in. Not to say building a turbo 4.3 is exactly cheap. I'd start with a new front bumper cover. When you get started put up a thread in the projects section.

LS it and sell the sy stuff to pay for the swap. :2cents:

I can't imagine a bum syty motor selling for enough to buy a Ls motor .

Realistically , your budget should clear the path to this answer . Have you sat down and figured out what types of goals you want for the truck in regards to speed desired ? Are you able to do a complete swap and re-wire yourself ? Potentially with standard setbacks , you could be down for a month .

Hopefully this isn't your daily driver ? At a minimum you will spend lots of money , create lots of headaches , and be without an s10 to drive for weeks .

Why? You're better off with the 5.3 stuff. The LS1 heads have larger combustion chambers which will give lower compression and the intake doesn't flow well enough to bother with it. A nice set of heads, a cam, and a good tune would probably do you wonders.

What would be a good setup for my syty engine to get me in the 12's
