WTB: SW20 BRAKE BOOSTER

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

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

Surely you can find one in Australia somewhere...

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 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.

I might have 1 but wont know untill the weekend if so willing to send to Sydney 

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

As far as I know the 'fat' boosters were only on early model JDM models about 1990, and the check valve will be mounted on the booster body on those and I doubt if you could use it anyway with a later booster.
 
All the other boosters are 'slimline'
They all look the same except that the '90 model ADM cars had a 'slimline' booster with the check valve mounted on the booster body. They only used a 7/8 "M/C
 
Later boosters only have a hose neck connector on the booster body (see pic) and they all used a 15/16" M/C
With those, the check valve is mounted in the engine bay on the intake manifold.
I believe that probably was done to give more volume to the vacuum system.
 
You can buy a 10 mm check valve that you should be able to easily insert into your existing vacuum hose on the manifold.
My car is an NA I have done that myself. I also have a later model booster with a Supra 1'' M/C
BTW, horrible brakes without the check valve as you can imagine, and there have been posts on the forum about that.
 
A check valve like this should fit, although I used a Honda one that looks about the same.
