Can I run the TBI off a 89 Track/Kick on a 86/88 Samurai?  I was going to swap for the 1.6 but after tearing it donw I noticed that the block was cracked between the 2 and 3 cylinders.  So after weighing my options I will probably stick with the 1.3.  The difference in displacement between the 1.3 and the 1.6 doesn't sound like much, but it is really a 25% increase.  Would the ECM be able to meter the correct amount of fuel for the 1.3?  I've got the Hawk billet torquer cam, Calmini tri-y pipes, and hi comp pistons.  I think, but could be wrong, that my 1.3 mill could use more fuel but I don't want to drown it.  Also what are the pros/cons/compatibility issues with running a 1.6 head on a 1.3 block, or visa-versa?  Any info would be great.  Thanks.

I think the ECM will cope witht he smaller engine
just fine, besides EFI is a cleaner runner than a
carb, and it don't stall out on hills

As far as a 1.6 head on a 1.3, they are the same
bolt holes and all, the only problem I had was the
1.6 head has no fuel pump location for a carb, but
I don't think you are going to need that, ohh and
the distributor for the 1.3 in the 1.6 head, has a tip
on the end of the 1.3 dizzy that won't let it seat all
the way, so I just cut it off, but you won't need the
1.3 dizzy either, you will need to use the 1.6 dizzy
to trigger the EFI system, keep the 1.6 and the 1.3
distributor drive housings on their respective heads,
I could never see what the problem was, but they
don't seem to interchange right.

Good luck

Does the 1.3 head not have smaller combustion chambers? In which case your compression ratio will be quite drastically reduced. i also believe that the ports are bigger on the 1.6 manifold though you could open up up the ports on the head to match. I read somewhere, ages ago, that the 1.6 with the 1.3 EFI runs rich so there is a possibility that it won't fuel correctly, it shpuld be OK during normal running if you have the O2 sensor to correct fuelling. Full throttle and acceleration could be out but you might be able to correct for that using the resistor trick, you might need to try a few values to get the right one though. Is the 1.3 EFI? if not you will need an EFI fuel pump, a Vehicle Speed sensor and probably a few other bits too.

If he is running a racing cam I would think that it would bring it back to stock on the fuel issue.

Thank you, gentlemen, for the advice.

The 1.3 and 1.6 8 valve heads have the same size combustion volume but the 1.6 runs bigger valves. The 1.6 16v head has a smaller combustion volume.

I hate to state the obvious.......

     If you are going to go throught all the work why not just get another block and do it once and for all. The cross breed 1.3/1.6 is not going to be a good trail/4X4 motor (IMHO).
     The larger valves, runners and ports on the smaller displacement means you will need to rev it to get any kind of power. The TBI is alot of work for minimal gain on the 1.3. Hit the wreckers and find a bare block (Hawk had a deal on them a while ago), build the 1.6 and then convert to the TBI.
     I think that you will be very dissappointed with 1/2 measures on this combo.

I run this setup, but it is on a stock 1.3 head, with a stock cam.  It really works good.  You will need a electric fuel pump, an inline ford model works well, and the complete engine harness and computer, intake, distributer,  from the 1.6.  The cool thing is that at a later time if you find a good 1.6 8 valve everything swaps over and bolts up really nice. (duh!)  '89 is the best model year kick to use because of a lack of a vehicle speed sensor in the speedo.

Off road this thing is awsome.  Just remember to kill the ignition WHEN you roll it over, because it can keep on running.  The power (or lack there of) is smooth and predictable, and she always starts right up.

It is definately a swap worth doing, I have seen directions for wireing on the web, it seems like there is only 7-10 wires that have to be tapped into to get it to run.
