i know someone had to have thought of this idea before. but im wondering how well the stock S4 turbocharger would work on the Chevy 4.3. Basically i have two spare chargers laying around collecting dust, and i have a 4.3 motor. Curious if i could combine them.

My question would each half of the 4.3 produce enough exhaust gas to drive the turbos? This would be a twin setup, so each turbo would only produce maybe 5lbs. Thoughts?

 

The 4.3 could spool those turbos, certainly, and make some HP with them.

Overall the TII turbos are crap for efficiency, and not well sized for the application though. If you want to put a turbo on it, headache will likely be saved by spending the money up front for a good single, or a pair of better sized, more efficient twins.

 

You would be better off using Ford Tbird/SVO turbos or Buick GN turbos. I think you would choke the 4.3 with those tiny things. The inlets to the stock T2 compressor wheels are schmiggly.

 

a guy locally out here put an s5 turbo on his old style sentra se-r. that thing was WICKED fast!!! i dont know that it EVER got beat before he sold it. he would consistently beat dyno-slip proven faster cars with each race. . . just kept on moving up the ladder. hehe, funny thing was that it was pink!!!. . . well, it USED to be red.

 

i remember those videos
he smoke a late model cobra r with it....

i think he actually blew it up while racing the cobra....wierd ****

 

he didnt blow it up. . . i thought he did as well. it was a spark plug that broke off at the ground electrode. it did a little damage, but nothing a little massaging didnt fix/help. the car was sold to a guy in clarksville, tn. he has yet to get it running well. . .

 

You will be suprised at what can be had from a 4.3.

I know it is not a turbo setup but it is forced induction.
