im an eclipse worshipper, there is no GSX spyder...
spyders are not rare?? maybe just around your area. anyhoo, they have 8g turbos...try getting an aftermarket 16g. will help some of the lag.
gsx were the rare ones, but again, no convertible gsx made. unless he has a gst spyder, then you are working with a SOHC. the GST had the DOHC...
