Brand new Holley on ebay ideal for someone wanting to convert their V6 to carb. I need an Edelbrock instead. Canadian buyers, keep in mind you won't be stuck paying PST, GST and "brokerage fees" (already did that).

and the advantages/disadvantages to goin carborated would be? What all would be needed for the swap???

Advantages are huge, the stock intake totally sucks. Wont flow anything above 4.5 k. Thats why we sell better intakes for those that to stay with FI. But even going the carb route will let you put a better manifold on it.

does anyone have a carborated setup on a 2.8. What did it take? How much power gain/loss? Any threads on this conversion?

------------------

somebody had a Trueleo EFI 2.8 that made like 205WHP and a Carbed 2.8 that made like 210-215WHP, they both cost right on $2,000 to build

i think those were 3.4's though.

Carb? Bad move IMO.

Here is my old thread. https://www.fiero.nl/forum/Forum2/HTML/074542.html You'll see all my errors and experiments. I now have it running well.

My engine did not do as well as some other carbed engines. I should have put in new rings to bring up the compression. Also, when I ported, I did a full port which raised my power up between 4,000 and 5,800 rpm. However, I lost low end torque. But, the carb/Edelbrock parts are mostly an improvement. I found the 1" - 4 hold phenolic spacer improved torque on the engine.

If you put the carb on it will definitely breath better. Your gas mileage will be comparable. As I mentioned, I need to raise the compression on my engine to get the full benefit out of the carb. I am currently working on bringing the power band down and the torque up. Doing it again? I'd recommend putting the carb on before doing headwork.

I think orief did that thread and you got it backwards, the FI made more power!

The carb'd engine and the EFI engine made the SAME power at the flywheel. These were 3.4L engines.
The carb'd engine was hooked to an auto trans and put down 197 rwhp. The EFI engine put down 205 rwhp thru a getrag 5-spd manual. There is less driveline loss thru the manual trans, hence the 8 hp difference at the wheels.

Here is the thread comparing the two engines:
https://www.fiero.nl/forum/Archives/Archive-000001/HTML/20060206-2-066575.html

Each engine had the same long block. (same mods) The only difference was intake and fuel delivery. The point was each engine made the same power regardless of fuel delivery used. The carb'd engine cost about $1600 to build and the EFI version was about $2000.

I originally built the carb'd engine because at that time there was no readily available intake that could flow as well as the carb'd intake. Hence, the 3.4L was able to exceed 200hp normally aspirated, which no one was able to do with the EFI and the Fiero intake set-up. Later the Trueleo came out and changed that.

Originally the amout of power was the biggest advantage of going to a carb. That is no longer the case.
Now the only advantage's would be cost and personal preference.
If you have a slightly modded 2.8L, 3.1L, or 3.4L and want more power over the stock Fiero intake, The carb is cheap and easy to do. The Trueleo is more expensive to do. The power gained would be the same. Either way is highly recommended if you want to get the most out of your pushrod 60* V-6.

Here is what a carb'd 3.4L looks like:

Would I be able to transplant a 85 s-10 blazer carb. 2.8 v-6 into my fiero? Just the intake and carb. setup? A friend of mine says i can have it if I want it

------------------

Yes, a 60* S-10 intake would bolt up, but the that intake & carb was designed for torque. I doubt it would be an improvement over the stock Fiero EFI. I also doubt that a S-10 intake will have the potential for increased power with further mods. Finally, if I remeber correct, those carbs had computer control needle valves and I don't know if it would work. I used to have a 2.8 Blazer. I would not put that intake on my car.

You can use the intake manifold and distributor. You would get better results using a larger 2-bbl carb like the Holley 500cfm 2-bbl carb. The stock carb for the S-10's was only 300cfm's. Holley makes a 350 cfm and a 500cfm 2-bbl.
You don't want to use the engine because the heads on the S-10 are the small valve heads. The Fiero heads are the large valve heads. The S-10 block has a smaller cam designed for low end torque as well.
With the larger 2-bbl and a decent exhaust you would get a little more power than the stock 2.8L.

thank you!! I'm gonna go that route! I'm tired of the trouble codes, clogged injectors, ect ect....


Once i get this up and running properly, I'll drive it till i get some cash and better weather,then I plan on upgrading to the 3.4L with carb setup like the other threads have.
