I'm looking for a later model SW20 'slim' brake booster to replace the original 'fat' one in my 1990 SW20 turbo.

I have big brake upgrades installed front and rear, and I've already bought a new 1 inch master cylinder, so now I just need a suitable brake booster to complete the upgrade.

I'm located in Sydney and I'm hoping to find one of these in Australia instead of having to buy one from overseas.

Has anyone got something suitable?

I think I've got one from my 98 half cut...

Yay! If you do have one, would you mind posting a few photos? I would mainly like to see the part numbers on the top, and the shape of the booster.

Sorry Rob, I was wrong. I must have sold it with my old engine, gearbox and other bits and pieces :(

No worries, thanks anyway Rick.

I found a suitable booster on eBay, but it's in Hong Kong, so I'll wait a few days in case someone else in Aus has one.

Surely you can find one in Australia somewhere...

I don't know whether you know it or not but there were several different 'slimline' shape boosters used.
Maybe best to look for one fitted after 11/93 - they are more powerful than the ones fitted after '92  when the larger brakes first came in.
 
Also with later boosters they put the check valve on the intake manifold and not on the booster itself, so you'll also need a 10 mm check valve.

Thanks for the info. 
I did notice lots of different part numbers on various slimline boosters. 
I was told that the most important thing is for the booster to be the slimline shape, but I should look for the latest one I can find.

Thanks for that. I heard something about the check valve but I didn't know any specifics. 
 
EDIT: I saw some part number diagrams of the brake booster and vacuum lines for the early and later model SW20s, and I could see that the check valve only exists in the later model diagram as you described. It looked like it would be located on the firewall, not so much 'on' the intake manifold, but either way it should be easy to confirm so I'll have a look tonight and confirm if there is no check valve in the engine bay of my car.

Will you definitely be able to find out on the weekend? If so, I'll wait and see what you find. Thanks :-)
