Whos actually done a full bolt on 4.3 rcsb?anyone?know wonder how fast they would be capable of....:ugh2:
before yall start saying just swap for a v8...thats out of the question....the truck is my younger cousins 06' RCSB 4.3 (college truck)
im sure we can get a 14 maybe 13 sec truck out of it
I know my 97 was a dog until Nelson tuned it, then it came alive, for a 4.3 that is. They can be decently quick for what they are. Tell him he may want to look into the marine intake swap, pretty sure those are popular with the 4.3s 4.3L Vortec Marine Intake Conversion Helpfull Hints: - FullThrottleV6.com -- The V6 Tech Source
yup thats the first thing to do...TUNE
I had intake, shorties, high flo cats, flomaster, tune, and I went 16.7. I could hang with stock 5.3s
So add a 200 shot and there is ur 14's.lolQuote:

my cousin has a 4.3 in a 05 rcsb sierra, hes done a little work to it and it still sucks. if i were him id just do a sound systrem and wheels and lower it.
gears...they usually stick some turd 3.08s behind the 4.3
mods availabe for the 4.3 lol
exhaust
intake
headers
pulley
thermostat160
comp cam
stall
servo
4.10s
5 speed? so at least you can get a decent launch. my 4.3 is just embarassing 17.8 ftw
17.8?thats stock rite?
Yeah that was absolutely bone stock, 5speed 3.23's.
tell your idiot cousin to finish college, get a job, then do the right mods. Damn kids dont have the right priorities anymore.
hey why dont u just chill ^^ out damm....as long as hes paying for it who gives a shit right?didnt know there were "wrong" mods lmao
He'll find out it's a pointless endeavor all on his own. All else fails and he still wants the 4.3, marine intake and turbo.
Maybe fab up a rear mount turbo? Couldn't be too much different than one for a V8. Maybe just use a smaller turbo.
turbo be nice...i know them 4.3 syclones were fast,,light,but fast.
shit he mite end up getting a new vehicle who knows maybe ill end up with his truck for a project ;)...ill pull that 4.3 in a hearbeat lol
i'd hate to be the bearer of bad news, but you really need to let him know he'll be better off swapping for a V8 - much more power for the same or less monies.
i know you mentioned that was right out, but friends shouldn't let friends waste that much time & effort. that's my opinion anyway.
(ps - that's coming from somebody who was adamant about not swapping engines this time last year)
wait... stock 5.3 RCSBs are that slow? that makes me feel much better about my 15.8 now - thanks! :DQuote:
