i just prefer things to be perfect to reduce chances of mechanical failure, especially with this much power now.
ok after much thinking, i've decided to keep the existing engine & gearbox left untouched on the car and simply bolt the new turbo stuff into it. will be cheaper and faster.
but first i had to figure how to remove the rusted oil feed plug on the head that i previously left cos of fear the tiny allen key'll round off.
i stuck on an allen socket and gradually applied torque but experience tells me this plug's not gonna budge with such tiny weak allen head and will round up, so i tried it again with some mole grips on the side, same thing.
so now i tried my bolt extracter tool since it cuts into and grips onto the outside of the exposed plug and walla it releases

ok with that verified, that's the plan then
