egate size/brand?

[mopo824]

So I am in the market to put an egate on my truck, which is a 95 12v. I will be swapping out the II62 to a 66/74/14 over the s480. I want to put a gate between the manifold and the s366. Reason behind this is obviously the pressure but its also peace of mind for when i spray if i do. i am pushing around 60psi with no spray and the 62 right now i am guessing i will around the 80-100psi range if/when i do spray. the 100psi is a high mark which i will probably not reach but this is just in case. i have been looking at the tial gates and i am unsure on what size to get? i was recommended to get a 50mm but they dont offer one from what i can see. I saw that E.D. has some on their old site but not their new site that might be a choice. i plan on running it to the ground unless its not acceptable then i will just pipe it into the down pipe. it must be the kind that comes with a flange to mount to pipe like you would mount on a steed speed manifold. Not sure if it will make a difference in what gate i get but the 160 pump will be coming off for a 13mm to take its place. any help is appreciated let me know what you do from your experience.
