Radiator overflow tank for Brat 2.2T

[Naked Buell]

Hey guys,

I have the 2.2T in the Brat, can I use any overflow tank that I can fit in there? I have the one tank on the engine, and I have the line off the radiator cap, to go to an overflow, like in the EA82.

Any thoughts and advice?

Thanks

My EJ20G-swapped EA82 uses the coolant expansion tank from a USDM WRX.  Works fine and isn't made of plastic

Now r u talking about the tank on the motor? I have the lame plastic one that came with the 2.2T stock. I am asking, if I have the one on the motor, do I need another one to catch from radiator cap to overflow?

Or do I just cap it? It is the stock Brat radiator metal.

Turbo legacy didn't have a cap on the radiator, the bleed came right off the expansion tank on the motor to the overflow tank.

 

I would put a higher-pressure cap on the radiator, and then run both hoses to the overflow, just in case.

Cool. I will tee off at the tank on the 2.2T motor and tie in to the radiator overflow line. If I have the stock Brat radiator cap what pressure should I get?

And what pressure cap on the tank on the motor? I figured I should have a new one too.

Do you have any pictures or perhaps a build thread? I have an EJ22T myself that is long overdue to be installed. I would like to see yours.
