Hyundai Performance Forums: "As well, as far as Accent swaps go, the Beta is a perfect candidate... it gives a significant power increase, even if you leave it N/A; it requires little custom work to make it fit; and even though the Beta has never been sold as a turbo motor (unlike the 4g63), the Beta is a tough motor, with a strong block, and can be turboed reliably.

If I were you, I would buy an x3 Accent, (so far, I think there have been many more x3 Beta swaps than there have been with the newer LC) and find a good quality Beta motor (they can be found on e-bay fairly regularly) and do that swap. The Beta can be swapped in with the Beta transmission OR it can be used with the Accent transmission too, if you prefer.

Many other Tiburon/Elantra piece fit the x3 Accent too... the front brakes are one example I can think of right now."
