sounds like you have 2lt-1.
unfortunately i don't know a lot on them.
one thing to watch is they run a different turbo and manifold to the 2lt-2. i think you bought the wrong one.
the turbo exhaust in port is round on the 2lt-1 and square on the 2lt-2. the 2lt-2 manifold won't fit 2lt-1 head as the stud spacing is different.

piston oil squirter's i have no idea on those. try the aussie or uk toyota surf forums.
