Can anyone point me to some sites or information reguarding uprading and rebuilding <92 Chevy 4.3 V6 TBI enigines.

Putting one in my Toyota this Winter/Spring along with 38's

 

Same engine as the one in the s10/sonoma. Maybe check out www.s10forum.com or pick up an s10 manual.

 

the 4.3 is junk

went through 2 motors in a year back in 1995.
upgraded to a vortex 4.3 out of a 95 jimmy no worries.

 

if you want to really shock someone with your ride... go with a b16a 4 cyl engine... easily turbochargable to 500+ hp in a very light package.
turbo civic

 

4.3 crap laddy drop a 2jz in it

 

www.astrosafari.com

Theres alot of info on there for performance 4.3 rebuilds and the 4.3L is far from junk!

But really why not just drop a 350 chev in her?

 

I do agree, the 4.3L is problematic, however if done proper it can be a star!!! Just like any engine I guess!!! But whynot go that extra mile and get something proven to be faithful and relaible? The 4.3 is not even a gas effiecent vehicle!! I had an 05' blazer and went through an engine and when we traded it in was begining to tick! I do admit I am hard on my vehicles!! lol..But with a Toyota your options are alot more open!!!

 

2jz, 1jz, rb20, rb26, vg30, and last but not least the sr20, ... can make more power then you could ever dream of...
gotta love oldschool yota and nissan.

 

Vortec.

 

the 3 series 3800 engine from GM would be my choice in a mid size vehical
