Welcome Safeer. We're a rotary car site, but we like all types of cars. Despite some of the trash talk.

Most here would encourage you to stay with a rotary. The 1UZ or 3UZ will destroy the balance of the car. The chassis was designed to have the engine behind the front wheels for weight distribution. Almost all other engines are too long and will push the chassis into a nose heavy balance unless you cut the firewall and do an engine setback. This has it's own share of drawbacks. Doing this depends on how much compromise of comfort and utility you're willing to tolerate and how good you are at custom fabrication.

Some don't really care about the balance though and are just looking for straight line acceleration. In which case the engine swap makes more sense. Depends on what you're looking for from your car.

Either way post up some pictures when you get underway with your project. We simpletons like pictures. :)
