Brakes are something that you should spend the most money on. It's your only real defense in an accident outside of driving ability and reaction time.

I have that size and rock the zcar kit. Works amazing
-
Failed designs. The compression was neat, but the two blocks I tested have a sharp edge that tears the rubber/ silicone.
-
I am going to make -8 and -10 AN adapters, the design has gone from compression, o-rings and finally going to tapered seat, either chilled and pressed in or pressed in.

All ITB test fitment is done. Cable mount is perfect, everything is smooth and actuates as good as I hoped. Now time to bolt it down, cut the cable to length and finish some wiring. I lined up the MZR haltech tuner to help me with my tune. It should be interesting to see how good he can get it, especially with my balance bar design and throttle angle. Will the snow melt so I can drive it soon? Probably not.

So nice

I think everyone knows Derek's head is superior.

That was mostly a joke\

I got my cnc intake and some parts back from media tumbling, it looks almost cast. I am super happy with the finish. Only issue it now shows finger prints.

I finished the injector wiring. I cheated and used an RB harness and just redid a few of the lengths to be perfect.

I was actually knee deep in making this myself. I am glad I pulled back a few months ago. My goal was to mass produce them, go cheaper. Nissan didn't say they aren't going to sell them, a writer for a magazine did. I was told from a nismo engineer that it's not off the table. I guess they are blown away with the response.

Finally got the linkage sorted on my ITB. This is without an over head bar return spring (I will add tonight). The system is very smooth and returns strongly. Pretty stoked.
-
Machine marks, they are pretty heavy.

ITB update! I got the dog bones/ rods shortened, design and had the cable mount made plus the fuel rail mounts. It’s almost ready to bolt in! I might try some surface finishing on the cnc intake. I don’t love the look of it.

I told him to remove it, he said its marketing 101.

I would do the one six personally, that tiny godzilla is ugly as f.
-
I use modern injectors, so high impendence. Batch injection should be avoided.

I was told by Rebello that there wasn't a HP benefit they saw from wasted spark to fully sequential, I honestly did it just because it wasn't hard. Cost me like 90$ for the jeep sensor mod, plus some wiring. A turbo dizzy can't do fully sequential. But can provide the ecu with enough info for wasted spark. I don't exactly know how the onesix unit does fully sequential, but I know it can. So it must provide 2 signals? Cam signal will have more "slop" in it, crank is superior for that. You can also use a flywheel trigger, but that is more rare. If you google or search for the jeep cas sensor mod, you will find info, I think either milkfab or bossa makes it so you can buy it already done. https://milkfab-engineering.com/shop/ols/products/milkfab-lseries-camshaft-position-sensor

Coil on plug means you don't need a turbo dizzy. Turbo dizzy would be traditional spark plug. You can use a turbo dizzy and coil on plug, but there are easier/ cheaper ways to do that. Crank trigger will be better then a cam signal, having both means you can run fully sequential, because the ecu knows exactly what stroke you are on. You don't need fully sequential, I have it, and I don't know if it truly helps or not. Coil on plug and wasted spark means two coils are firing at once, which I don't know if all ecus can handle that? The one six unit is nice, drops in and gives the ecu a lot of info. The milkfab crank trigger would be cheaper/ easier in my mind. My coil bracket (M2 Racing-r35 coils, and protunerz- LS coils) are the two on the market I can think of. Lots of guys fab up coil brackets, audi coils, plasma coils, coil packs etc... I have a crank trigger and jeep cas, so fully sequential.

I think there are a few Datsun guys that just throw silly prices on stuff, and sometimes people pay them. Turbo dizzys are always for sale on Yahoo Japan.
-
I will keep making more stuff, it's been fun!

I launched my Datsun parts company, for anyone looking. https://www.m2racing.com/

The intake is about the same length as a harada (about 2mm shorter) the jenvy one is longer and so is the cannon. It's all a give and take. My next intake design will be longer, shorter throttle bodies, injectors mid runner.
-
Well I got my cnc intake! Honestly surface finish isn’t what I was hoping for. But will be nice with some effort. I think it’s almost too much bling. I might go satin glass bead on the intake. It has pretty heavy machine marks Balance bar bolted on exactly as I planned, with 6mm banjos. The injector angle looks spot on as well. Pretty happy with it overall. Next rods need to be shortened and I need to figure out a progressive throttle location on the overhead bar and a cable mount location. Then moving the ecu temp sensor.
