KAAZ sent over their prototype LSD product, which uses a completely new type of clutch face material to reach high lock with very little noise, and extended life compared to the metallic type.

any KAAZ LSD housing can be retrofit with the new clutch packs to convert existing units.

pricing and release TBA

I am annoyed at a respected Japanese craftsman in the chassis reinforcement space for declining to work on this brace for me as a product. Ignore the clashes and hole details -- this was a mockup to propose work and communicate the packaging requirements.

Brace material would have been Ti or Al sheet, welded at the centerline to create a large cross section with low unit weight. This mockup uses a 10mm hollow section, likely .080" thick sheet, which creates rounded box sections. The crux of all forward brace products is that they don't improve the engine bay's torsional rigidity at all, and there is no direct connection available between opposite corners of existing structure. The hood is in very close proximity to the strut brace, perhaps 1.5-2" above the engine cover.

The original OE brace is very lightweight and was likely added as tension support to handle increased aero load on the very forward leading edge of that aero package. The lateral brace is there to prevent it buckling given the bends are there specifically for packaging reasons.

He gave this response:

>The radiator core support is made of resin; I feel that simply bolting a custom-fabricated rigidity panel to the two existing bolts there would not yield the expected results. That is precisely why [we have] not commercialized a bolt-on part of this type.

>I sincerely apologize, but we cannot manufacture parts where ensuring performance is difficult.

>Thank you for consulting us on this matter.

I think this is a bit silly, as my structures experience would say -- provided the underlying structure is sufficiently stiff, and bearing load is not an issue -- there is no functional difference of material of that structure.

Would like to hear from some structural engineers in industry what their thoughts are on reinforcing secondary structure.

testing surface finish options for printed model, given metal assemblies will be expensive

pistons were made by QUAIFE, and possibly the conrods too, which means I may be able to request the same parts under private label manufacture. NISMO prototype cams were made custom and will be sent to JWT for profile extraction, again to offer as a product.

​

MIDORI SEIBI also mentions a header design of theirs, which I'm seeing if they could make another of as a product.

​

ideally I can eventually release most of the NISMO COMPETITION lineup minus the crankshaft and heads.

it also has the protoype NISMO pistons, and prototype cams. I may bring the parts locally for inspection and reproduction at JWT's request.

​

really quite surprising to see this, it must be a monster of an engine.

There are tons of green rocks and some have fibers. Montana

I previously worked in composite structures, but this is regarding the OEM Nissan Z33 2002-2008 engine strut tower brace, which is metallic. It has a hollow inner core filled with polyurethane, presumably to dampen any high frequency vibrations between the strut towers.

It has a very particular M-shaped deformation to it. My assumption is that it preferentially deforms in the same manner under load, which would be better controlled by introducing a pre-bent deflection like this. It would simply deflect further into this shape predictably, rather than having odd buckling dynamics had it been a simple straight brace, which are not easily predicted and could have secondary effects. Note that hood clearance w.r.t this brace is very tight.

Looking for input from chassis dynamics or structural engineers who might clarify the M-shape functionality.

I can generally provide a 5% discount to those ordering through me, including unlisted products like the flywheel and clutch packages. DM for discount code.

we're still planning on the DE-HR conversion kit, but that's quite a big project and we're slowly making progress.

Selling off stock for MCR hood import and sway bars as mentioned. Prices are shipped to door.

$1400 for the S-tune exhaust, $1550 for the titanium Fujitsubo.

I'm working with a few small shops in Japan to offer fully rebuilt, as-new Brembo F50 (B) caliper kits for the R32 and R33. It is more than overkill for either platform (and my Z33) and will attempt to pry your face from your skull when used with TW200 competition tires, where it takes 2.5-3 car lengths to stop from 75mph.

This kit is specifically to fit factory 17" wheels.

These calipers have been fully disassembled, stripped, given new pistons and seals, polished, machined, and then re-coated in Gunkote high temp paint. These are genuine OE Brembo kits, not remanufactured copies.

This is the same caliper as the Brembo GT upgrade kit, MSRP $3950. A larger 355mm rotor setup is available for 18" wheels, shown in the second slide.

Kit includes new hard brake lines.

Rotors are optionally included, and use the V36 330mm rear rotors off a 370Z or G37 so may be swapped as desired. Pads exclusive to Brembo Racing, including dual use drive to track pads, are also offered for $350.

Sumitomo rear caliper kit is also offered separately.

The listing is active here on my site.

Shifting some standing inventory as I need to prepare for the sway bar shipment after we test lap times.

I have one remaining Vibra-Technics engine mount set until the next batch order, and will issue a $30 discount code to anyone who wants it from the subreddit. It can be ordered here on the site.

I also have a long discontinued Fujitsubo Legalis R Ti exhaust, and a NISMO S-tune exhaust on hand.
