A-Trim or S-Trim????

[quick89gt]

Ok, here is the deal, everyone. I have $2,000 right now. I was wondering if I should save up and buy an S-trim to run 8# of boost on my combo listed below, or if I should just save some money, but an A-Trim, start @ 5#, and then pulley it up to 8#, or will this HARM the A-Trim???? What do you think I should do? I want to make around 400hp with the blower and my combo listed below.
