My 1988 Mazda B2600 truck is great in every way except fuel millage 12-14 miles per imp. gallon and at times hard to start, I believe it is a carb. problem. I want to keep my truck, but want to replace my carb. Any comment would be appreciated.
Dude It is thee that are sadly mistaken, From 1987-88 all B2600 4WD trucks came with 2.6L mitsubishi engines I own one all original except for a brand new Mikuni Solex electronic carburetor which I can't get 2 idle when warm. Whats up with that? Bogs down on normal takeoff, but accelerates great when stomped. Got rid of the jet valves did a 3angle grind and dumped 2 of the 3 catalytic converters. Also eliminated the balance shafts and replaced timing chain.
This is true, 87-88 B2600's were Mitsu's... I don't really care for the design of the engine either, but it seems to run fair.
Anyone out there ever try to turbo charge one? I am considering doing this to mine. I haul two quads with mine, and with all the camping gear it's fairly gutless. I took all of the smog stuff off of it, installed a red line carb, and got rid of the balance shafts. Maybe it's the 33's that make it gutless, but I need the big tires to get out on the dunes. I have a good turbo off a Z car that I would like to try.
Hey, I have had absolutely no problems with my 87 b2600 until now... at 99k my truck stared to make a grinding noise when the engine hit higher rev's. I think that it is a timing chain problem and with a few of you making comments on th timing chain I believe I may be right. any comments would greatly be appreciated. so here is to the ONLY import I will ever own. go Mazda!
I have a 93 Mazda b2600i. I have never has any problems with it until now. It stuttered almost like it was running out of gas. I tested for spark, compression, looked at the electronic control and tested the injectors. Everything checked out. I adjusted the distributor all the way over and it started, but it doesn't have any power. I think the timing chain slipped. Can anyone tell me (without buying the expensive book) whether I can adjust the chain with the tensioner or will I have to change out the entire chain? Any comments would be welcomed. I love this truck and I want to keep it, but It has 163,000 miles on it.
1989 Mazda 2600 fuel injected. I want to throw mudders on my truck, but I don't know what size I can put on without changing the original setup. I'm thinking about throwing in a 4.0Litre B4000 engine V6, but will this pose any problems with engine mounts and space requirements. This truck overall has been very reliable, starts up in -40C (guessing 0Ferenheit) weather, 4cyl is gutless true, but a 4L V6 has 209 HP original, imagine a bored out, K&N, exhaust, chip setup will put it over 300HP for sure. Then maybe I will need a new transmission and axles. Another question is when lifting a truck like a Mazda, should I go with a Dana 40 front axle or leave it the way it is? I would love to hear your input on this as I would love to just jack it up, throw mudders on it and just go bogging. Thanks.
What kind of mileage have you guys been gettin on your trucks?? Thanks.
The 87-88 Mazda 2600's were junk. I had one, and I was very unimpressed. 89 and newer are much better than their predessors. If anyone is looking to buy one, it is worth the time to get an 89 or newer!
I have a 92 B2600i with 125K. Recently I had a problem that happened one day without warning. It acted as if it were running really low on gas, had bad gas, or had a clogged fuel filter or bad pump and stalled out itself after running just fine for only 10 minutes. Then it got really rough and stalled. The next day, it would run fine again for 10 minutes, and then stall. After a bunch of research and troubleshooting, and a CPU refurb, it was the Ignition Pick-up off of the distributor. Crazy. Other than that, the truck is good, gets about 15-17mpg.
I am on my 2nd '93 B2600i 4x4. I thought I would never find another extended cab model, after I tried to climb a tree with my first one; totaled it.
The truck is great. Just wish I could get better mileage at interstate speeds, but I get over it when I go off-road.
Does anyone know the gearing in the tranny, t-case, and axles?
I never thought much of these Mazda B2000/2600 pickups, but the mining company where I worked in Bolivia used them, and I gained new respect for them.
The roads were atrocious, so these little pickups took a constant beating and kept on going, with minimal maintenance (the closest thing to a garage there is driving up on an embankment so somebody can crawl underneath it). They were our only contact with the outside world. They proved to be reliable and simple.
The only possible downside was that they were a little light to get much traction, and washboards would break the rear loose from the road. They were also really susceptible to the ubiquitous water-logged gasoline, so pulling the fuel filters and blowing out the water was a must or they would stall.
Power wasn't that great, but it was really good considering they were carbureted and running routinely at 10,000-15,000 feet above sea level.
Don't buy one, piece of crap!!!
I got my 1987 mazda B2600 with only 68500 on the odometer for 150.00 bucks with a frozen motor, but the body and interior is in perfect condition well after about one year and 5000.00 bucks just for engine parts including a balance shaft elimination kit I finley got dun rebuilding the engine. when I started the engine for the first tine the idle jumped way up to 3000 rpm right off the bat. I freaked out and shut it down. after a new change of under ware I adjusted the carburetor and then it ran fine after that. the jet valves are a joke so I got rid of them. now I'm having an issue with the engine temp sensor witch is a hard to find part. this truck might be a money pit, but I LOVE MY TRUCK.
I just picked up a 90 b2600i and it has a misfire on both 3,4 and I can't figure it out got spark, fuel, and compression help!!
I have a 91 B2600i. It runs great, but dies when shifting to 2nd or reverse, or stopping while the clutch is pressed down. What could cause such a problem?
Check the ignition. Had the EXACT same issue with mine. Gentleman, replace EVERYTHING fuel related. I bought it cheap and put in a rocker switch in place of the "ON" for the ignition. Problem went away. It's common on these. The ignition switch just gives out and there's only a tiny spot where the power will stay on (aside from when in the "START" position). Replace the whole switch or install a rocker switch to use in conjunction with the key, which is what I did. Check the black with yellow stripe wire (10 AWG). It should have power in "ON", but not "ACC". If not, that's the problem.
Hey guys, I have an 88 B2600. Was wondering if anyone knows of a motor that will bolt up to the transmission with little to no fabrication? Thanks.
Mine does the same exact thing!
If anybody could help with this problem, it would be greatly appreciated!!
Mine always died when warm. Later I found it was the water choke. When it built up pressure, it would leak into my intake... stupid. Didn't find out until I had already bought a Weber.
5000 is a lot to spend... I rebuilt mine for like 1000 with a parts truck. For 5 grand you could get something like this: http://www.racetep.com/starengine.htm
Same exact engine. They put it in all kinds of stuff, and for 5000 it could be a very fast truck.
Check out this site before you judge the truck; it's filled with potential without an engine swap.
It's a great truck. I take it everywhere and beat the hell out of it!
I have rebuilt it and done a bit of research. I'm gonna swap the axles with Toyota straight axles; A arms just don't cut it. Then I'm gonna beef up the engine so it doesn't bog down when I put 33s on it. http://www.racetep.com/starhead.html
That website helped me a lot. I suggest checking it out.
