factory internals

what is the cheapest and SAFEST way of getting the most possible power out of a non turbo toota supra 93-98 i am new to toyoa engines and i am not sure what the factory internals will take before they decide to die

any ideas??

The NA motor is the 2JZGE. The turbo version is the 2JZGTE. Toyota stock internals will hold double the stock HP. I don't know of any NA buildups. If you are looking for cheap a bottle of nitrous is as good as it gets. Beyond that I would recommend an engine swap. The cost of turbocharging the NA motor vs swapping in a turbo motor makes working with it cost ineffective. If you don't want a turbocharged engine then you might consider swapping in a 1UZ FE or 3UZFE. These are the aluminum V8s in the Lexus line of cars.
