Is it a good choice? do they suite for 997.2?

 

I run boost up to 1.8 bar

I dont think those are the right thing for a 997. From my understanding the forge ones are the best for 997. But im no expert

 

Leaky stock ones look like this;







I replaced mine with Forge as mentioned above, they seem to be the best design of the aftermarket options. It's probably a good idea to lubricate them every now and then though.

 

Here you go...in stock and ready to ship

These are NOT for a 997.2 these are for the 997.1. The DFI engine went back to BOVs as the 996 used. The GT1 engine uses BRVs as are listed in this thread...you need to see the link I posted in this thread. Regardless of whose BOV you decide to purchase, this is what you'll need.

 

How do you know if there is a problem or leak with the oem brv on a 997.1tt? I.e what symptoms?

 

Or these.

There weren't any symptoms on mine. Pulled the two cap head bolts and looked. It was probably minor... But once I knew there was a hole in it I couldn't put it back in.

 

is it a diy job with jacks?

 

Rix, are you still happy with the Forge units can't seem to find the BorgWarner 179424 EFR Compressor Recirculation Valve (CRV) Kit B1/B2 instock anywhere.

 

That's what she said.
