Depending on the price, check out what an engine swap might cost ya. Several guys over at the college automotive program are into rock crawling rigs, or off road and beat them pretty hard...they tell me the 3.4 engine is cheaply available.. all of them seemed to have done the swap....
The 3.0 was the same engine as the Camry's I gather....
I've got an 88 with the 2200 RE, 540 K on that one.. am in the process of replacing the head, figuring it will be cheaper and better than just getting my head refinished.
The one I have picked up is suppose to have 30 PSI higher compression than the factory one had.
Some of the GM V6s were also a common conversion back in the day..., they seem to be available cheap enough, with conversions to bolt up to the Toyota manual trans.
