1,3,4,2, is the firing order on cars with line 4 engine .
Well to correct your post there was not a b2200 in 1981.It is a b2000.The firing order should be 1,3,4,2.This information actually applies to several mazda engines like the 1,586cc,1,796cc,1,970cc, and 1,998cc and last 2,184(the true b2200) from late 86 going into 1987.Amazing they all share 1 thing and fire order.
1,3,4,2 Number one is at timing cover closest to the distributor.
The firing order on all 86-93 Mazda B2200s is 1-3-4-2 when facing the distributor from the driver side it turns clockwise. The terminal facing the front of the truck on the distributor cap is #1. Below are some related links that should help.
Taken from the Haynes Repair Manual for Mazda Pick-ups 1972-1993, the correct firing order(all engines) 1-3-4-2,,note cylinders are numbered (front to rear) 1-2-3-4. Chapter 2 part A.
For starters the 1986 year model was a b2000(however unless Mazda made a late version of the 86 as a b2200 maybe possible) Anyway any b2200 engine Mazda made for the bseries that was fuel injected is compatible.You will have to have the ecm and wiring harness for the ecm from the fuel injected engine in order for it work.The b2200 was fuel injected after 1988 I believe and it was not on all the 1988 models they switched in mid production to this.I will not swear this to be exact with details but,generally the 1986-1993 models are interchangeable for the most part with pretty much the whole truck.Just note by changing to fuel injection is not a cost advantage in the long run.If you just need a engine,compare the cost to upgrade,time versus just doing a good rebuild (I would) not to mention switching harnesses,ecm, etc.If the engine needs a tear down I would suggest that,cheaper,less bs,and wiring nite mares hooking up.Just my take on the overall picture!
