Hi,

Am I right in thinking that the wastegate is located on top of the engine, next to the cast induction pipe and connected to the inlet manifold via 2 flexi pipes and one solid?

Cheers,
Pad

Ooops! What the hell is that on the top then!?

So, back to my original thread - is it an internal wastegate or external?

Cheers,
Pad (a so called engineer as well :( )

Yes I concur Richard, it is in integral wastegate as standard on the inside of the exhaust housing before the downpipe.

Cheers,

As the wastgate is integral to the turbo, is it still a diaphragm mechanism that is commonly used on external wastegates?

Can I get to the pipework (pre wastgate) easily?

Sorry, been a bit of a muppet but its the first time I have started poking around in there...

Cheers,
Pad

the wastegate is a metal FLAP. with an arm which extends to the external side of the turbo hence the Actuator arm reaching to he front of the turbo, can be seen on most turbos.

Thanks - if you would indulge me and further my turbo learning... :)

Where does the pressure build from in order that the actuator opens the wastegate at a given pressure?

Thanks again,
Pad

Gtirpad i just did a search & found a pretty good article on turbo mechanics. Take a look.
Even better would be to go to a tuner & see if they`ve got any blown (or new) turbos lying around you can look at. Its quite simple once you`ve seen 1 off a car. I learnt about them by changing 1 myself on my old Lancia.
