Distributor ??

[TopStreet240]

hey guys, the turbo kit is on a running, the car fired up for the first time in three months and did pretty well. The only problem is the car would get really choppy when she reved past about 2000 rpm I was wondering if anyone might know what this probem could be and im also wondering if there is any ground wire that comes off the distributor to the block or chassie. a pic of someones ka224e distributor would be really helpful, thanks much guys.
