+1 on that. if you think about swapping transmission (manual) go 5speed.
i paid 750$ for a very nice rebuilt t5.
3spd didn't bother me in the slightest. what i needed was the overdrive gear. when you go from 3 to 4 your gear ratio on highest gear will not change. it will stay 1:1
so for that the onky difference is that you would have to switch more often between first and fourth but as soon as you're driving 60 you'll be still missing the next gear you'd usually want.
on top of the T5 you'll need a few parts like a new shifter, an adapter plate and you will have top get a different yoke and might to adapt your driveshaft.
It was hassle for me as I live in europe, but WELL worth it
the petrol you save with a t5 is immense if you drive highway a lot

1sweet65,
Please specify: are you talking about converting an automatic 3-speed to 4-speed??
Then you want an AOD trans from a later model. You won't notice much diff in MPGs unless you do some hiway driving though.
We were talking manual trans, then go straight to 5-speed. Just get a hurst shifter to keep that origional look. There's no MPG advantage from 3 to 4-speeed on a manual. The 4-speed just keeps the revs up while racing.
