anyone know of any good after market websites for 4.3 liter? i have a 2000 silverado with a 4.3 and a 5 speed. im lookin for nething that will make it go faster, and shift better. i cant seem to find anything for it. im really wanting some long tube headers and a few other nethings, but anything would be appreciated. i have also thought about puttin a turbo on this motor after i rebuild it sometime down the road so if you know of any kits for a 2000 silverado with a 4.3 in it id love to know where. thanks guys

nelson tune or wait4me tune for starters

can they even tune a 4.3?

Find the turbo set up from the Cyclone, it was a V6.

Yes they can do a tune on a 4.3. Get some performance parts on it before you spend money on your tune, make it worth your while.

Just my :2cents:

what exactly is a nelson tune? do they make a chip for you or wut i cant quite figure it out, i have never heard of them either. and how much does this normally range and how much power does it add? i know nothing about nelson tune i need all the info i can get. thanks

Click the link to his thread and read up. If you want I will have the guy that just got his 4.3 tuned Wednesday get with you.

yea if u could have him get with me sometime email would most likely be the best way

If you're tryin to build up your 4.3, good luck. I had a 4.3 in my current truck and some bolt on mods (headers, exhaust, intake) and that thing was slloooooowwww. Dropped in a V8 and the difference was like night and day. Now I'm not telling you to go swap out the 6 for an 8, because it's a pain in the ass (but worth it). Just giving my :2cents: on the matter. Even if you turbo'd it, you still couldn't touch a built 5.3 or 4.8 for that matter (trust me, I've killed turbo'd S-10's)

They really don't make a whole lot of aftermarket parts for the 4.3 anyway.
