Well I decided to pick a new header. I wanted the header to give my room on port 5-6 for my lower mounted actuator and also get out of the way of the throttle bodies a little more. I decided on the Kameari drag 45mm. Which I purchased through Binh Nguyen. The header design gives me plenty of clearance for my actuator and throttles! Pretty darn happy with it overall. Prior I had a now moth balled Fujitsubo header. Which had a terrible runner design for a lower actuator.

240z hidden drive by wire actuator for my ITB setup. This is design number 4. This plan utilizes a Efi hardware actuator. The goal is the same length arm to the bell crank and distances from shafts and the rod. So the rod passes through the firewall evenly and doesn’t walk from left to right. This will mount to the pedal plate and the steering box mounts. So behind the firewall Prior designs walked too much in the hole and I don’t want that.

I bought them as well!

A little update on my 3.1L! This motor was actually finished 3 years ago, but was tragically in a shop fire. Luckily the engine wasn’t too close to the flames and it was spared. It’s getting close to finished and then going into my 1971 240z! My 3.1L 10.2:1 compression ratio 88.5mm bore. N42 block. Sonic tested. LD crank by marine crankshaft.

Port work by Andrew Kazanis Dsi valves, titanium retainers. Isky springs. Bonk cam. I got it in NOS or near new condition prior to porting.

Mine is 88.5x88.5x.25x3.14159x 84.6x6 /1000 = 3122cc Thank you Andrew Kazanis for all the help and your magically porting work.

You can get a oil temp sensor, oil pressure is a must sensor for the ecu.

Sweet! Working on the actuator, I am now trying the efihardware one.

Could it be tie rod roll?

I love it when a plan comes together. This is custom titanium banjos, which will come off my balance bar and hold my heat shield on!

My friend Andrew just rebuilt this motor and has been working on this historic Z race car. Pretty epic

Well I got my prototypes in for my passive cooling on my Efi hardware throttles! These will be between the heat shield and the throttle bodies. Also it will be a nice and clean way to run the return fuel.

Custom grade 5 titanium studs of my design. I am so tired of installing the old studs and I hate the look of the allen ones. I designed intake, exhaust, my intake balance banjos, knock sensor stud, stack studs and my intake intake/ throttle studs! The flat spots work perfect with a box wrench. I also love the look of a rounded tip on a stud. I think they came out awesome, after testing I will be selling. I bought enough, that they should be fairly cost effective as well.

Bosch off a BMW. I ordered the studs already! They are nice and cheap.

Dual L6 knock sensors using the stock block m6 hot water pipe mounts. They are actually about perfectly placed! These are just ti prototype. I am designing my own and will be adding them to the things I make and sell.

So fast!

Well drive by linkage is fast and accurate. Pretty darn stoked. I might try a few more actuators. Since the one I picked is being discontinued (BMW S54 13627840537) This should make anyone doing ITBs life much easier. Cold starts, traction, AC, intelligent throttle curves. This is just hooking it straight to a 12v source. So it’s just on or off. Actually when wired to the ecu, closing will be faster. This is returning via springs. When hooked up to the ecu. It’s powered open and closed.
