    Approximately what diameter should the hole in the block be?

    Regards,

    The factory hole is around 16 mm, but even 10 mm would be fine. Bush65 has posted a pic of the hole on a 4BD1T before.

    Mine wouldn't be any bigger than 12.5mm as that's the biggest plain shank drill that will fit in my chuck.
    The diameter of the drain on my turbo is probably only 10mm, and fed via a 1.6mm restrictor without any drainage issues, so I also agree that practically 10mm would be plenty big enough.

    Update

    Nugget made the first prototype last week, my job over the long weekend has been to fit it.

    Attached are some photos of the process.
    First photo is a grainy photo of all the kit to be installed.
    Four lengths of M10x1.25 HT Rod were cut.
    2 x 110mm
    1 x 195mm
    1 x 210mm

    Second photo is a picture of the old cartridge style filter once removed from the block.

    Third photo is the side of the block with old filter removed.

    Fourth is a picture of the filter profile before being drilled. Note it has cast in plug where the hole needs to be drilled.

    Fifth is a picture of the engine block internals once the sump was removed. Note the threaded hole was for one of the four bolts was not blanked and went all the way through the block. No idea why?

    Next photo is from the sump again, this time with the 10mm hole drilled through.

    A photo of the filter profile with hole drilled.

    A photo of the spacer with the filter profile gasket, showing where the holes are.

    Next photo is of the main filter housing installed with the bottom spacer.

    Last photo is of it all installed.

    All in all, not that difficult to install.
    There will be one change for future spacers - the top spacer has M8x1.25 bolts through to the engine block. The holes in the spacer I used were 12mm diameter, going forward they will be 10mm diameter.

    Will talk to Nugget tomorrow about timing of the first batch.
    I think the plan is to make them into a kit with M10x1.25 HT Rod, not sure about the M8x1.25 rod yet.
    Hopefully they will go for sale shortly on Nugget's new website!

    Will update later this week when everything is cleared up.

    Thanks again for the interest,
    Cameron

    Hi everyone.

    Firstly thanks to Cameron for the time and effort he has put into doing the ground work.

    With a couple of small mods it all looks good to go. I am happy to provide the full kit for $180.00 plus freight. The kit will include :-

    the 2 manifolds CC machined from Aluminium billet
    HT rods cut to length
    HT bolts, nuts, washers and spring washers

    The only requirement from my end is that a minimum of 5 sets is ordered and paid for before I start cutting. Delivery would be approx 1 week from receipt of the 5th payment being received.

    Kits will be available later as a single buy but the price would be $260.00 plus freight. I will include them on my website which should be up in a week or so..watch this space...

    If anyone has any questions, please send me a PM or you are more than welcome to call me on 0414 778 668.

    Cheers
    nugget

    Thanks Nugget, good work. Got mine from the post office today. Didn't expect them to be one piece items - bonus - must have missed something in the thread, I expected the multi-layer format.

    General point for all. Still getting familiar with the engine. Regarding the smaller single oil channel unit. The old unit has a pipe running off to the turbo. To me, once the new extension unit is installed and capped with the old unit this pipe will need lengthening - cut and lengthened with new pipe silver brazed for example. Or entirely replace with something longer. It also looks to me like it might be possible to tap and thread the new extension unit, missing the bolt holes in the process, and saves altering the turbo pipe. How are others approaching this?
