I have a 1987 4 runner that was efi, due to electrical problems I put on a 32/36 Weber until I could get a good wiring harness. Now after much tuning my truck runs great and is very dependable. I have now acquired one complete, and one 75% complete efi system. My question, is the efi as dependable as the carb? I know that with a spare coil, distributor, and fuel pump I can probably fix whatever breaks on the trail. But not so sure about fixing something on the efi on the trail.
I know that a properly running efi will outperform a carb any day. So what would you do, swap back to the efi, or leave the carb that runs great except up hills?

 

I say keep the carbbed one! My old 86 Carbbed with 32 inch tires and stock gears and me ( a teenager) driving it, got 19 MPG city. Not bad IMO Also you don't have to deal with the engine computer and excessive electronic crap that comes on EFI. I guess im old school like that. Not to mention you already have it carbureted, dont fix it unless its broke

 

It all really depends on what you do with your truck. Both EFI and Carb are very reliable, it is just important to understand them. Unless you are frequently stalling out due to steep angles I would keep the carb.

 

in my experience, i've had my carbed engine running at very steep angles, with no loss of power or any sputtering..
the only time's i've had issues were when my distributors would get wet after a water crossing and the truck would sputter and run like hell.
so far i've seen no extra benefits to having EFI on such a small and simple engine, except for the marginal increase in MPG and power.

However, i have seen some various other issues with the EFI.
Most notably the o2 sensors, EGR valves, and many other components going bad and costing an arm and a leg.

 

thanks for the replies

 

I've been burned by both, so go with what you know and keep what's working.
