All R31 skylines came with the same engine as the VL series two which has the 3 holes in the block for oil return line etc which the VL series 1 didnt have. so no problems there.
Stock injectors will work, but will be holding you back, and again intercooler is not needed, but is recommended.
Also you will need to track down VLT ECU and the list goes on.
I suggest you head on over to www.ozperformance.net and do a search for "turbo conversion" as it is quite often discussed there.

this is what you will NEED
vl-t exhaust manifold
t03 (or better) turbo
water and oil feed and return lines (4 in total)
crossover pipe (or an intercooler)
inlet pipe (if your using an air-box)
the n/a inlet manifold/plenum outflows the vl-t one.
get the vl-t computer, and injectors.
to use the vl-t computer in the r31 wiring loom you need to rewire the fuel pump to the air-regulator. theres a detailed explaination in the forums at www.r31skylineclub.com under frequently asked questions.
run from 15 (stock) down to 10 degrees ignition timing (depends on your motor), 9psi is most really without a decent cooler.
id also be looking at a clutch upgrade
