FLYNLOW

I have a t25 custom setup for my 95 del sol si. It was put in by my friend about 3-4 weeks ago. Everything is pretty much stock because I just bought the car about 1 1/2 month ago. I would like some advice on how to strengthen the internals and keep my engine running safe. I read about replacing pistons, camshaft, connecting rod, head gasket, head studs and etc but there's so much that I need to replace and I don't have a whole alot of money to spend so I need to spend it wisely. Is all this really necessary since I don't plan on running high boost? I just want a daily driven car running about 8 maybe 10 psi. Any help would be greatly appreciated.

PS If anyone has a similar setup, please email me.
