Hyundai Elantra Forum The Hyundai Elantra Forum. Later models (96-up) of this 4-door share their Beta engines and chassis with the Hyundai Tiburon. Earlier Mistubishi-based Hyundai Elantras (92-95) are perfect candidates for the popular 4g63t motor swap, which turns the Hyundai Elantra into a real sleeper. These characteristics make the Hyundai Elantra a great car for those who want sports car performance with family car flexibility.

Good news for Beta2 Owners (2001 Elantra and 2003 I4 Tibby)

BV1 Can you get the diameter measurements of the inner and outter belt surfaces of the AOS pulley? (or get circumference and I can do the math).

The differece is, the AOS pulley does not have the Harmonic Dampner built into it like the stock units and RPW unit does.

Interesting that the Betas would use two different weight pulleys....

I'm guessing that this means that the Beta uses the pulleys not to dampen any significant harmonic distruptions but for emissions and noise/vibration/harshness issues.
