What other 4.3 vehicles can I pick parts from when I'm in the junkyard that will work on my 94 4.3 W. I know the Astro vans are one, are there any others.

Also why is the CPI different from the 1st Gen and the 2nd Gen trucks? Whats different about them?

Thanks

 

You can find the occasional 4.3 in 1/2 ton trucks too. They came with a 4.3, 5.0, or 5.7... So if it looks like a bare bones base model, you might find a V6 in it.

Also, I have seen 4.3 in LADA 4x4 trucks, its not like they are going to be allover your junkyard, but I found it interesting to know that those old LADA 4x4 trucks have the same powertrain and computer as a blazer.

 

I'm not sure what all will actually work but this is a list of GM cars with a 4.3

• 1985-2005 Chevrolet Astro/GMC Safari
• 1991-1993 GMC Syclone/GMC Typhoon
• 1988-1995 Chevrolet Blazer/GMC Jimmy
• 2001-2002 Chevrolet Express/GMC Savana
• 1988-2003 Chevrolet S-10/GMC S-15
• 1994-2001 Oldsmobile Bravada
• 1985-2001 Chevrolet C/K

 

the only thing different about the cpi is the computer on gen 1it is obd 1 on gen 2 its obd2 on gen1 there is only 1 o2 sensor before tho cat on gen 2 there is an o2 sensor before and after the cat

 

The Savana/Express vans are probably the most common... Not sure if things are interchangeable though.

 

Sorry for my stupidty but what is a LADA truck?

Thanks for the list of vehicles, alot more then I thought.

Ok so are the CPI Fuel Injectors interchangeable, say I was to find a CPI in a newer Gen 2 would I be able to use it in my Gen 1? Are they designed the same? The only reason I'm asking is becuase they have 2 different part numbers, if you look them up on Summit. I dont want to pick one from the bone yard from a Gen 2 and not be able to use.

Thanks

 

This might give you some information about the LADA truck.

thanks, its a cool rugged little truck. but yeah I doubt I would ever see one, let alone in my bone yard.

any more info about the difference of the CPI's?

 

I just replaced the inner and outer fenders as well as the hood. New parts came off a 94 S10 Blazer, mine is an 88 S10 Blazer.

 

sorry everyone, What I ment was differece in the "Spider's", for some reason I was thinking CPI instead of Injector Spider.

Whats the difference in the spiders from Gen 1 to Gen 2? Could I use a Gen 2 spyder in my Gen 1?
