what would be the weight difference between the 2 engine choices? Will probably be running EP here but would like to have the option to run ITA to maximize track time. Not looking to be nationally competetive or anything, just looking to get on the track and do some racing as finances permit...

personally i have had a hell of a time working with cis-e compared to the motornic setup. If i had my choice it would be 'squirted but trying to build something that fits into our regional classes haha!
