I am doing a d16z6 build made for boost cuz I just don't have the income to swap in a b-series and boost it. I picked the sohc cuz of how cheap it was ( cost me $350) at the junkyard, and I can sink some money in the motor so it will hold boost without takin a crap on me, hopefully anyway. I had a few questions and figured someone can help me out on here.

1.) Will a t3/t4 hold 25 psi safely without putting a lot of stress on it in the long run?

2.) With all the engine management systems now available, which one is the best to go with now? Which will give me the best options if I change parts around later and what not?

3.) I have heard a lot about the Johnny racecar intercoolers, but is it a good investment compared to a greddy or spearco?

4.) My last question is where can I find an exhaust manifold that isn't some ebay crap, that actually has a decent reputation, cuz I can't seem to find a honda turbo exhaust manifold for the life of me.
