Yup... make sure to get the right timing belt. BT is 101 tooth while SVT is 111 tooth. Just get original Toyota timing belt, unless you're using aftermarket cams. Oil seals better change all three.
Here's what I paid about 4 weeks back in Ipoh:
AE111 Timing Belt (ori Toyota)= RM130
AE111 Koyo timing bearing set= RM115
Oil seals x3 = RM60
Total= RM305
Also, its better to change the timing tensioner which costs another RM150.
