well there a couple 4 cylinders that is a good swap in ,one being the
tried and true ford 2.3 that thing has been modified and used in
everything from street cars to race cars and there are performance parts
avaible for them the best ones to get is either the ones from the
rangers or bronco II they are heavier built and have a better
compression (it has 9.5 to 1) and you can get 4 barrel intakes for them
or use a conversion from racer walsh in florida and use a efi injector
intake that once you unbolt the upper plenum it looks like a 4 barrel
intake ,
now a second choice is the 2.2 out of the S-10 it has plenty of torque
and they are inexpensive and you can get the computer setup pretty easy
too and if you do some upgrades you can get upto about 250 HP out of it
naturally aspirated since the stock hp is 180 and just the addition of
a supercharger you can get about 250 to 270
out of it in street trim ,hope this has helped you to know you have
other alternatives .
good luck
