Why can the GSX go faster then the GST? It's the same engine and less drivetrain. Do the trannies have a different ratio?

 

only some of the gsts are speed limited to 130 for safety because they come with H rated tires. if you fix that or its not limited it will be a tad quicker than the gsx because its like 150lbs lighter and loses less power to the drivetrain. a gsx wil go 140 stock and gst can go up to about 145

 

Ahh, all that new fangled speed limiting crap, who needs it.[:'(]

 

Ok so if i buy a gsx motor and drop it in my car and just upgrade it from that. Can some one tell me a place where I can buy a gsx motor?
