Moving the waste gate actuator pipe.

(1/3) > >>

Disco_Stu:
When doing this (I'm sure a lot of you have come across this before), you move the pipe from the turbo to the back of the plenum chamber where there is a a handy unused drilling and blanking bolt. The bolt is removed and replaced with a banjo or similar fitting. What size is the drilling and therefore the bolt?

Hopefully its 1/8 BSP like everything else banjo related on Discos but a bit of clarification would be handy.

For those who dont know about this, moving the wategate actuator pipe to the back of the plenum means that actuation takes place based on the pressure at the valves rather than further around the turbocharged loop, minimising loss through pipes, mico leaks etc, hence turbo comes in earlier and with less lag. A lot of people report really good performance increases after doing this mod.

Any help appreciated, Stu.

Does that not act in the same way as increasing the boost though, which apparently 300's don't like.... needs to be checked with a boost gauge to keep an eye on whats going on really.....

Disco_Stu:
Not as far as I know. From what I read its more like making everything happen more quickly rather than more forcefully. It doesn't open the wastegate further (Like the 200tdi mod you're thinking of) just sooner. I think :)

Any photo's of where you disconnect it ffrom and where you connect to? just for clarity   :?

Disco_Stu:
Have a look at this, I havent done it yet. I like to have all the info to hand before I embark on my next disaster :)
