Okay I have 2 trucks. A 1986 4runner with a 22r weber 32/36 conversion 29" tires, and a 1994 Pickup with a stock 22re (with some sort of torque cam) on 32" tires. Both 4.10 geared.
Now the weber was used and came off a jeep, the long block condition is unknown but was sitting since 2006 in a field. I daily the 4runner and struggle to get up to speed, the thing is dog˟˟˟˟ slow, like I get passed by ˟˟˟˟boxes left, right, and center. When I get into the pickup its like stepping into a sports car, it's peppy and I can even do some nice burnouts in it.
Now my question is would the 4runner be slow slow because it is worn out, or is the EFI really that much better then an aftermarket carb. Everyone online praises the weber for being faster then the stock carb, but there is never any comparison between that and the RE. I can't even spin the tiny tires on the 4runner. Flooring it takes a good 30 seconds to get up to 80 km/h. Is it worth rebuilding the block and keeping the carb, or should I swap in a 2L diesel out of an old hilux, the motor is just on a stand in my shed. I've heard they're pretty slow, but the fuel mileage and torque is tempting me.

 

To try to judge the carb without some data is not much help.
what cfm is the carb?
Is the cable allowing full travel and fully opening both barrels?
Do you have an air/fuel meter to see if it is running rich or lean at WOT?
if that all checks out, what is the general health of the engine? Compression test?
Are you getting the spark advance you should be getting?
Put a vac gauge on the engine and see what it reads at idle and while driving at WOT. If it doesn’t approach zero, carb is restricted or catalytic converter could be plugged.
Just the basic tune-up and hotrodder stuff.

 

Yeah what Melrose said about AFR at WOT is key to getting performance out of the Weber. You can have it dialed in at idle, if jets aren't right you might be running lean at speed, burning through valves and struggling with power.

 

I have a Weber 38 on my '87 22R 4WD running 33's and love it. I had a 32/36 and it ran pretty good but not quite like the 38. Been running it for many many years. It obviously won't set any speed records but it's way better than it was with the stock carb. I have no issues in around town traffic but on the interstate running above 70 is difficult. The secret with a Weber is jetting and proper tuning. It's not a bolt on and go carb. I found out the hard way. Lots of time spent tuning and jetting in the beginning to get it running well. As "Melrose" said, could very well be other issues besides the Weber.

 

the weber 32/36 in my jeep doesn’t like much fuel pressure. i have a regulator on the line to limit fuel pressure to 2 or 3 psi. i don’t know what the mechanical pump on the 22r creates for pressure, but if it is 6 psi or higher, that could be a problem.

 

Like the others have stated the weber must be setup correctly to perform.
Fuel pressure no more than 3 psi. 2.5 is ideal. If your running the stock pump than its getting too much fuel pressure. stock pumps put out 6-8 psi. Recommend a holley fuel pressure regulator. Don't cheap out.
Verify proper operation of the vacuum advance and make sure you have the vacuum line hooked up to the correct spot on the weber. LCE sells a new vacuum pot if your is worn out.
If the weber came off of a jeep its likely jetted wrong.
What adapter are you using to mount it to the intake manifold? the adapter plate that come with it is junk and know to create vacuum leaks. LCE sells a good adapter and so does transdapt.
Whats your base timing set at?

 

I have a holley FPR set at 3PSI. Also have the transdapt spacer. Running at 8*TDC with a ported vacuum line. I have a vacuum gauge, at idle it is around 21, WOT it will go to like 1-2. Regular acceleration is around 10-15 which on the gauge says bad fuel economy.

 

what super said is key here. jetting. no way a weber from a jeep has the right jets. what jeep motor? i hope not a 258 or 232, not even close in power band of a 22r. call someone like lce or redline and get a jet kit. i did the weber 32/36 setup on my 20r and it was amazing. set the pressure right (like mentioned above i had about 2.5) and let her eat.

 

I tried messaging LCE but aparently they don’t have jets for a DGAV. I guess they’re different from a DGEV(?) What jets are you running?

While I'm far from being a Weber expert I would find it odd that the DGAV (Water Choke) would have different jets than the DGEV (Electric Choke). Call or email Redline Weber. They were extremely helpful when I had a warranty issue with my 32/36 and even advised me on tuning my replacement 38.

i bought mine directly from redline i believe, and they claim that theyre already jetting and set up for the 22r platforms so rejetting wasnt required. sorry i dont have more info on that. but it ran awesome once i got it set up and for the fuel pressure dialed in.

 

I too bought mine from Redline (both of them) but they were not jetted correctly. Follow Redline's setup instructions EXACTLY then get your jetting correct and you'll be happy.

 

Also what do people think about the n/a 2L diesels?
