@Racer bhai ...
I agree with you as EP82 is lighter then EP91 ... 
Actually I am talking about a big community on internet like us on PW ... (www.toyotagtturbo.com) its a discussion forum ... where people talk mostly about Starlets and nearly 90% of their discussion based on Starlets... every one there own a starlet ... on PW if you ask some one to advise you what should be better way to enhance performance then there are very few who can guide you about starlets ... but on that forum people are very expert as they are practically involved in starlets modifications ...
I just want to say if some one is totally focused on a high performance starlet project then he can consult with those people … I am member of the said forum for around one year and I learn a lot there …
I don’t exactly know why but mostly people there prefer Glanza over EP82 … you can find members there who use starlet as a daily driven car … and members who are seriously involved in drag racing …
I am not advertising any other forum but just sharing my experience …
