Help, I Need Parts!

[angusis2fast4u]

So i have foam coming out of the radiator which means headgasket is gone. I have been told that getting a new RB20 is cheaper than doing the head purely because of the whole machining process. So I thought I might buy another RB20 with box (I need a new box as well) and clean it up and put it in when I have the time. So I will need a few things...

RB20DET: Where do i source this from? Sure i can buy one of someone who has a "vgc" rb20 for sale but i'm working on a bit of a budget and would like to buy an engine which I feel confident in knowing that it will work.

Gearbox: I have contacted Nissan A1 Wrecking on this before and they seem to give you a reconditioned, not serviced, box for $850 which I don't think is too bad. Is this the right place to source the box?

With both of the main parts sorted now Will i need?:

Clutch: Could i reuse my current one? or because it's going onto a new block will i need a new one, if yes, Where do i source a cheap Exedy sports tuff clutch?

What else will I need for this? / What else should I do while i am replacing an engine?

('92 R32 GTS-T) and I am located Brisbane.

Any second hand engine or gearbox is going to be a gamble.

I would check what they mean by reconditioned gearbox, because that seems pretty cheap. However no one wants the 20 box so that could be why.

Of course you can reuse your current clutch. You just have to be happy to pull the box off to replace it later on. Most people replace the clutch while the box is off, depending on the condition of it.

Before you get carried away I would want to be 100 percent sure it's the head gasket and not something silly.

You can buy kits to check if the head gasket is blown. They work by detecting hydrocarbons in the coolant.

You wouldn't want to pull it all out of lying to find out the previous owner put some weird shit I the radiator to fix a leaky water pump......
