L28 Block Girdle's

[luvemfast]

Hi guys.

I'm not on here often, mainly into the older Datsun Z's. But thought that some guys here might be interested.

These used to be sold by Neil Cartlidge a decade ago.

With Neil's permission, I have re-modelled these to be made available for sale.

I gauging interest for Block braces / Girdle's to suit an L6.

They are custom made, laser cut from high tensile steel. Very nice bits of gear.

Think of it as cheap insurance for your engine.

For all of those people complaining about leaking rear mains............ Thats due to crank flex.

This also makes the entire block more rigid, increasing durability and performance. Neil swore they moved the harmonic vibration up the rev range.

Street or race spec engines can benefit by the correct fitment of one of these.

The girdles are fastened via many different methods depending on other accessories.

They bolt through the mains using either longer ARP studs or Unbrako socket head cap screws (M10x90mm from memeory). Both methods require spacers approx 10.0-10.5mm (dependant on individual requirements) between the mains and the girdle. Hardened washers must be used for both methods under fasteners.

If using stock sump, you should use the small pilot holes in the girdle as a drill guide to drill and tap M8 into the block webbing. This should be done during a trial fitment of the mains caps, so that everything is in the correct positions. When the girdle is removed, drill the guide holes out to a clearance size and counterbore to suit an Unbrako countersunk screw.

If using an Arizona Z Car aluminium sump, use Unbrako socket head cap screws to fasten through original sump holes.

Threebond can be used between the layers to seal them.

I think that pretty much covers it.

Will they work with a front sump arrangement as Zeds are rear configuration?

Hmmmm, that is a very good point. One that I didn't think about as I only have rear sump blocks......... Are they any different? or is it the pickups that change?

Soooo......

It will fit. But if the pick up is in a different location, it will be missing the 3 holes needed.

Is the dipstick hole in the same place too?

If someone can supply me the dimensions, I can add them to the CAD file.

Thanks anyway for looking guys.

Looks like I won't get any made up due to lack of interest.
