87 tc hydroboost or vacuum?

[Jdrudy]

Hey just bought a 87 thunderbird turbo coupe. Pretty cool car so far but the teves electric booster is shot and they seems to be obsolete unless I want to get a used one and those systems don't seem super reliable in the first place. I want to convert to either vacuum or hydroboost. Hydroboost is more ideal but vacuum is like half the price. Engine is stock right now but I want to start slightly modding and eventually rebuild the engine and try and push 350hp. So what do you guys think go all out with hydroboost or is vacuum going to be good enough?
