I am currently putting a T04 on my 32 and try and help you, your turbo probably dosent have a wastegate so you will need an external one, depending on the size of the turbo you may be able to modify the stock exhaust manifold to suit, a wastegate will cost about $650 for a new one and to get the manifold done will be about $400 ( im only guessing on this as i did mine myself on my labour is free).
You really need to have the turbo looked at to see if it is worth doing, the one i got was fairly small so it shouldnt be to laggy.
You will need a fuel pump, and your injectors will max out after about 220rwkw. The you need some sort of management either a power fc or microtech plug in which rpm does or one of the hundreds of other ECU's.
