Borg Warner EFR6758

Just a few pics of it mounted and its positioning etc.







You will see in the next photo a small hose between the recirculation valve and pressure port. This is the best way to plumb it up on our TD42 as we dont have a throttle body like a petrol would.

And another one.

With this setup we are utilising a turbosmart EFR specific twin port wastegate actuator. We are for the moment keeping the standard injector pump on so have gone for a 22psi spring arrangement.





Clearance to inner guard.

The idea behind using the Turbosmart dual port actuator is we can have finer control over the actuator. We get this control from using a electronic boost controller, in this particular case a turbosmart Eboost street.

So with these 2 parts working in partnership with other we can have very accurate control of the actuator which equals boost control. See with the dual port actuator we can have pressure on either side of the diaphragm. This means we can hold it shut when exhaust manifold pressure is trying to open it. Also we can basically control exactly when we want the wastegate to open. With a normal type actuator the exhaust manifold pressure can start to overcome the spring before you have given it signal to do so.

The other great thing about the turbosmart actuator is you can put a number of different spring combinations in to suit your desired boost curve. This again gives you that finer control over a conventional style actuator.

Very interesting this is. Im keen to see how this goes. Been eyeing these off for a while. As for the ceramic coating. Is it just like a pressure pack can job? Or do you take it somewhere? Thanks.

Eyeing off which bit? Every turbo setup will benefit from electronic boost control.

Better to send it to the professionals. The manifold is also coated on the inside.

Induction time. So, as I always recommend, we are running 4" piping all the way to the turbo. And I mean all the way. We only step it down right at the turbo. We have used a Fatz Fabrication airbox on this setup. With some nice flash pipework



A few different angles.

Next up is the charged side of things. The intercooler we are using is of the water-to-air type. I have gone a little further with this though and the cooler is now integrated into a modified intake manifold.

First things first. Mount the support bracket.

Next up the manifold/intercooler unit installed.

Some pics of the mountings. Obviously in chopping the manifold up we lost some of the original mountings. Easy fix though with some blocks of ally. You will notice there is extras of most things just to be sure we dont need to add anything later on.
