Well yesterday my piston went in my 92 Blaster. It pretty much took a big chunk out of the it and I am gonna get it bored out to .40 over. It was allready .20 over. Anyways, should I just stick with the Wiseco piston or is it worth it to get the Vitos super stock piston? I like the sounds of 5 more top end horse power. What is the life span of it compared to the Wiseco? If anyone is running one in thier blaster right now please give me some input. I really like the sounds of it. And will I have to run race gas or will I still be able to get away with 93 octane even with the higher compression? Please reply. Thanks

Go with the Vito's if you can afford it. My son installed one in his Blaster and is really happy with it. There is a substantial increase in Horse-Power. He runs "pump gas". He also installed a K&N Filter at the same time.

i have a 99 blaster and just recently put a vito's piston in it. I went from standard to .040 and to me it seemed like a pretty big difference. The powerband is alot stronger. Also my friend's blaster has DG pipe, 12 tooth front sprocket, rad valve, and i have a FMF pipe and the vito piston and i can smoke him. I hope i helped. And i run 91 octane and it is fine. it only raises it 5 psi
