94 vs 88 1.3

I came up with a 94 1.3 to replace my tired 88. I am going to run the My-Side set up that I have due to the simplicity of it.
But my questions are.

1. The head on the 94 has a place for a fuel pump but when I put the rod in the hole it does not move at least that I can tell. I am thinking I will have to run an electric fuel pump with this engine. Am I thinking right or will the mechanical fuel pump work with the EFI head? If not what is a good easily available electric pump for this application?

2. 88 engine = square tooth belt and timing pulleys with a 4 bolt v belt pulley, 94 = engine has rounded tooth belt and timing pulleys with a 5 bolt serpentine belt pulley. The timing belt on the 94 is a rounded tooth and when I swaped the crank pulley for the 4 bolt pulley the square tooth on the bottom pulley and the round tooth for the top pulley doesn't look like a very good set up. I guess I need to swap both pulleys from the 88 engine along with the correct belt? Is there anything I need to know about this before going ahead and doing it?

Kind of simple questions but my cheap ass manual does not cover stuff like this. I figure someone has been through this swap before.

which ever way you go you do nned to have both top and bottom timing belt pulley match, because the belts are different. As far as electric pump your looking at $35-$40 from the part stores, since your going back with the MySide you only need about 2lb of fuel pressure so go with the 2-6lb pump, and you will need to keep using the fuel pressure reg. that came with the MySide.

you are thinking correct... there probably isnt a lobe for a fuel pump rod on the efi cam... I am no help on which fuel pump to choose...

2. 88 engine = square tooth belt and timing pulleys with a 4 bolt v belt pulley, 94 = engine has rounded tooth belt and timing pulleys with a 5 bolt serpentine belt pulley. The timing belt on the 94 is a rounded tooth and when I swaped the crank pulley for the 4 bolt pulley the square tooth on the bottom pulley and the round tooth for the top pulley doesn't look like a very good set up. I guess I need to swap both pulleys from the 88 engine along with the correct belt? Is there anything I need to know about this before going ahead and doing it?

You do need to swap the cam gear also... Just follow the timing instructions in the manual and you should be ok!!!

Kind of simple questions but my cheap ass manual does not cover stuff like this. I figure someone has been through this swap before.
Good Luck

Thanks guys, I knew you all would be some help.
I would leave the serpentine set up on but I don't have the alternator or water pump pulley for the serp. Plus my v-belt has a 2 groove pulley for the future addition of power steering or on boarb air.

I would guess you could go to a salvage yard and get the serpentine pulleys off a 1.6 that would probaly work.

1.6L 8-v Trackers/Sidekicks have the same 5 bolt pulley pattern and serpentine set-up. At least the 2 of them I had did... You should be able to use the pulleys of one of those engines, so they shouldn't be that hard to find in the junk yard.

As mentioned.....
The EFI cam does not have a fuel pump lobe on it.....you can either swap cams or run an electric pump.
The trackick 5 bolt crank pulley will work on the samurai 5 bolt crank. You can get these in double row, so you still have something to run PS or OBA.
A trackick alternator will fit in the 1.3 bracket. A trackick water pump pulley will fit on a 1.3 water pump. I run a full serpentine system on my EFI 1.3 along with trackick PS.
You do need to keep the same type of timing belt pulleys on both ends....either square or round.....you could swap the cam pulley from one to the other, or swap the crank end.

I swapped the crank and cam pulleys to the run with the square tooth belt and the 4 bolt v-belt pulley. I have been driving it and it runs much better that my old engine for sure. Plus I don't have that oil smell that use to follow me everywhere.
Thanks for the info guys.
