As WJ said, it is in the factory location, I buy a bung that is made to replace damaged ones and weld it in place.

 

the X over pipe: I bought a cross over from Morgan from an EJ 22 turbo and am going to marry the best of it to the jig I got from Witte for the EA82

Looks good but you might also want to have 3/4" or so of pipe to slide into the outlet of the turbing housing to clean up the wastegate turbulance. It wouldn't even need to be connected to the down pipe, it's just a sleave. Also, I would build up the weld on the outter side of the wastegate pipe so you can radious the inlet on the turbine side. Otherwise, when the poppet valve opens at maximum, you may be blocking the wastegate tube, thus defeating its purpose.

I just used an orage-slice of sheetmetal to flow the wastegate exhaust right into the downpipe and it works awesome. This setup does make it easy to install an external wastegate in the furture though. Your new pipe should spool much quicker than the stock. You should take it for a spin before installing mufflers, cats ect, you will be amazed! That's how mine is all the time!

correct you are

this small curved section (basically a cut out

of a 1/2" long piece of 2" exhaust pipe) is welded to the flange

to direct the waste gate flow. It is not shown in this older picture.

 

The complete pipe is also wrapped in header wrap.

This keeps temps up and exhaust

gas flow as high as possible.

 

I run only a hi flow cat as a muffler as I have emission

testing.

 

 

The current waste gate poppet valve opens as far as the waste gate diaphragm will open it

within the relief cast into the turbo's flange.
