So this is my situation, i bought a MSP and it was leaking oil so i brought it to a shop and they said the turbo was blown so i bought the GT28 (this is it) and then when replacing the turbo the shop found that the turbo manifold was cracked so i replaced it with (this) then i finally get the car back and it is still leaking oil bring it back they find out cylinder 1 has low compression and is spitting out oil, so they are fixing that right now. My question is will the GT28 be okay with the stock internals or should i look into spending even more money and buying forged pistons and rods and having the shop do that eventually as well or if there is any other cheaper way to strengthen the engine?
