Default Power Problem

My 87 gl carb non-turbo has no power between 1/3 and 3/4 throttle. The power kicks in pretty good at 3/4 throttle, but the hesitation in the normal driving range is no fun. I've just done the normal tune up plus remanufactured heads, new head gaskets, intake manifold gaskets, and a remanufactured carb. Also just put a different lower end in from a wrecked sub. Mine burned oil and had a big chunk out of the intake valve on cylinder 1.

Weber 23/26 DGEV. I just got my 87 GL back together tonight, and it runs pretty decent. I can set the cruise and run hills without any loss of speed.. I spent a fair amount of money letting mechanics try to tune the car with the OE Hitachi carb on it. After a great deal of frustration, I finally tossed it and went with the Weber. The carb wasn't cheap, but the improvement is unbelieveable.. I would highly recommend it. It starts better, idles better. Runs low end much better.. I usually leave the car in 4th now to go around turns in town, as you can easily lug the motor down to 500 rpm. Then you can bring it up to redline quite smoothly.. Good stuff..

So What does a weber run for these cars? I've sure heard that alot of people on this site really like them. I 'm trying to make sure its not the distributer before I spend any more big bucks on it. I put it on a timing light last night and when reving the motor it wasn't a very smooth advance, in fact it almost ran better when the vacume line was off. Weird.

i am not sure what i paid for mine, but it was in the neighborhood of $400. I bought a complete kit from www.piercemanifolds.com but I would recommend just buying the carb and making the rest, as that is what I had to do. Their carb adapter and throttle hardware did not work on my motor. The kit did fit my EA82, but would not clear the P/S pump or A/C compressor. The bad thing about where I mounted the carb is that the spare doesn't fit under the hood anymore. But some day that space will be for a TMIC anyway...

I don't know too much about the distrib.. Mine seems to work okay. I can see vacuum retard and mechanical advance, so that is good enough for me. New plug wires, cap, rotor, and properly gapped plugs helped. I am also thinking of adding a hotter ignition coil to the mix.

Since the carb isa pain in the a.. to put in, how difficult would it be to put in fuel injection from the same year?

If you have two cars side by side, I wouldn't think it would be too hard. Having a good wiring schematic by your side would help too. Just move each and every harness and component, and you're done..

The carb shouldn't be a pain though.. I just got a kit with the wrong adapter. There has to be one out there somewhere that would fit EA82 motors. If you could find a complete kit somewhere, it wouldn't be bad.

I also removed all of the EGR equipment from my engine. I kept the carbon canister and canister purge so that the fuel tank would have a place to vent on hot days. I blocked off all of the EGR passages in the head, at the exhaust ports, and in the intake manifold. I also cut the catalytic converter in half and chipped out all of the catalyst. The car had been running rich for a long time, and about 60% of the catalyst had fused into a solid mass. Removing that also made an improvement in how the car ran. A clogged catalyst could be helping your car to run poorly. If it has been running rich, and there is a lot of soot in the tailpipe, your catalyst could be melted. It's worth checking out. Although I don't know how you would check it without cutting it in half the way the pipes are bent.. Worth a look for the sake of troubleshooting...

Quite honestly... if you want to swap in EFI from the other car... just use your good block and tranny in the EFI car rather than swap the whole wiring harness... MUCH easier!

If you want simplicity do the weber, its really not THAT Hard if you get a DFEV as they are "backwards" so they will fit on a GL without having to reverse them to clear the power steering.

I have 2 or 3 DFEV's not what I need for my brat (no power steering so the DGEV will fit) I would be willing to trade one of them (after its rebuilt though) and maybe some cash for a DGEV... depends on the condition of each carb (if both older, but rebuilt maybe like $20 from me to you) if yours isnt rebuilt then closer to straight across or if its missing afew parts then a couple of bucks to me..

PM me if interested
