has anyone dropped a 4.3 into there b- series and had any problem. I'm buying the ultimatecustoms.ca motor mount kit with tranny and suspention cross members. and have a cherry donar with all parts nessesary. any help with brakes, power steering/streering column, dirveshaft measurements (keeping mazda rearend), radiator swaps would be greatly appreciated!

 

haven't heard of that swap yet, but just my input, i would change out the complete drivetrain including the rearend. only because the stock rearend in our trucks is geared rather low. and with that added power i am sure that you want more of the top end. i know this will be a costly venture, especially to get the driveshaft custom made to keep all the geometry correct and keep the axle positioned in the same location it is currently (this is a important factor having the truck dropped, bagged or the like)

 

HEY, JUST A NEWBIE HERE, BUT FROM WHAT I CAN UNDERSTAND, MAKESURE YOU DO A LOT OF HOMEWORK BEFORE STARTING A PROJECT LIKE THAT. MY 2.2 IS ON THE WAY OUT (BURNING OIL) AND I HAD ACTUALLY CONSIDERD DOING THE SAME THING. THE ONLY THING STOPPING ME FROM DOING IT IS THE FACT THAT I DON'T THINK I'LL HAVE THE TRUCK LONG ENOUGH TO ACTUALLY WARRANT A PROJECT LIKE THAT. ALL THE POWER TO YOU IF YOU DO IT THOUGH. SORRY I'M NOT MUCH HELP.

 

i'm doing the same thing but using a turbo on the 4.3 i was told long as you have an overdrive tranny you would be fine. 700r4 or standard tranny i'm going with a 6 speed tranny

 

if you need a radiator you can use a 1974 chevy nova radiator you can get 2 or 3 core. it has the same deminsions but you will have to build mounts to hold it in place. what are the hose locations on the radiator in the s 10. the nova has drivers top passenger bottom.

I put a 4.3v6 fuel injected out of a 92 chevy 2500 into my 86 mazda b2000. i got everything done i just need to know how to get the fuel an dist. to work without the wiring harness out of the chevy. any advice would be greatly apperacited. thanks to all that help in advance.

 

An MSD igntion box would be your savior as far as the distributor goes. I would manually wire up the fuel pump with a relay to reduce the chances of frying an alternator and/or battery and put it on a switch! I don't know how you would get the injectors to go without purchasing some sort of expensive aftermarket computer though...Consider carburetor. Just my 2 cents!!!
