Having had some cold start issues, I decided to replace my glow plugs. Then I thought I would check my prechambers to make sure they are still good.

Then I thought, while I'm in there, I'll add a few upgrades to my 606.

I don't want extreme amounts of power, just doing a few mild upgrades.

I've already installed the upgraded manual pump with 7.5mm Diesel Meken elements and it's made a big difference. But with all that extra fuel, it now needs some more air.

Enter my new T3 G3077R turbo, Benzforce T3 cast manifold (ceramic coated), Turbosmart Compgate 40 High Pressure waste gate & Turbosmart external boost controller. This should give enough extra air needed to run within safe parameters.

Along with the extra boost, I am also installing stiffer valve springs. It's not really a necessity as I won't be boosting that much, but it can't hurt right?

F-Tune upgraded springs from Benzeforce.

And a few gaskets, valve stem seals etc.

And for those wondering, yes I'll be doing the rear cyclinder block cooling mod at the same time.

I will post some pics when we start the project.

Did the cold starting improve with new glowplugs?
We have not started yet. We start the project next week. No major issues with the cold start, just the plug light only comes on after one minute and then stays on for at least another minute. And there is a little miss fire for probably 15-20 seconds, then all is good. Resistance on no.3 plug was higher than the rest, and I suspect this is the issue.

New turbo. Proudly South African built G3077R from Turbo Direct S.A.. Built it their factory at Denel in Kempton Park.

Ceramic ball bearing, AR63.

Bespoke hybrid combination turbocharger. Forms part of a combination of the GTX30R turbine wheel with 8mm ball bearing cartridge and a modified and upgraded Forged, billet compressor wheel derived from the G-series turbochargers from Garrett.
The compressor housing is also a bespoke unit from a combination of the GTX and G30 housing designs and includes a ported shroud design.
This turbo is a TRUE 600-700HP output. (Not that I will be pushing anywhere near that, so this turbo will be lasting a very very long time) :)

It looks very cool Leonardo, keen to know how you arrived at the selection.
Would a turbo (good for 600-700 HP) not be very large to push the amount of air, thus resulting in a lot of inertia and turbo lag on a smallish engine like a 606?
Keep us posted on the project!

I won't be using all those horses. It should spool up quick enough, but I will only know once it's installed. Guys overseas are putting much bigger turbos on, and they do lag a bit.
