Hi
I HAVE A 2.8 L MPI , prod. year 1987.
During the first production years (1982-85) of the 2.8 L V6 (3rd gen) they made them with a 2bbl carburetor system . Is is possible to change the MPI system into a carburetor system ?? Is it enough if u change the intake manifold and add a carb , or is the bottem of the engine/engine block different? I know that the electrical wiring will be completely different and the ECM will have to go . Is this transformation possible at all?

thx for any advice and information

 

i have no idea what all is involved in the swap, however the bottom end and the block are the same

hope that helps a lil

 

thx for the info

you guys are probably wondering why I'm thinking about swapping to a 2bbl.. Well because during 1,5 years of owning the 2.8 L MPI Camaro i have had about 3 serious breakdowns, caused by faulty sensors and bad electrical wiring. I am sick of constantly changing sensors and praying for the service engine light to go off. The carburetor system is much more reliable, a few vacuum lines here and there, no dumb *** computer, and similar performance (115 hp to the 135 MPI hp. ).
I need reliability not fuel injection and "performance" .

 

alot of the s10's had the 2.8 carb too

i think edelbrock makes a carb for this app aswell

 

you can convert the 3.4 to carbs as well. I am looking at that for a kit car I am thinking about building.

Edelbroch makes the intake, and combine that w/ Holley's 4bbl carb. that setup makes about 200hp on a 3.4L Not emissions friendly, but if you dont have to deal w/ that, then it doesnt matter.

 

ok, so i understand that its enough if i change the intake manifold and add a carb , right ?

 

aside from the wiring issues, yes.... that is all ther is to it. I dont know what functions your computer controls other than the engine, so you might be able to scrap it and custom wire in gauges to your dash, or delete the engine wiring and leave the rest.

 

dude, thanx a lot for the info ! I hate this MPI piece of ****, nothing but problems !

 

Good luck w/ the conversion. Let me know how it goes, because like I said, I am planning essentially the same thing in the near future.
