DuffyMahoney Posted November 7, 2024 Author Share Posted November 7, 2024 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. 2 Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted November 23, 2024 Author Share Posted November 23, 2024 (edited) 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.

DuffyMahoney Posted November 29, 2024 Author Share Posted November 29, 2024 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. 2 Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted December 4, 2024 Author Share Posted December 4, 2024 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! 2 Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted February 3, 2025 Author Share Posted February 3, 2025 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. 2 Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted March 18, 2025 Author Share Posted March 18, 2025 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. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted April 8, 2025 Author Share Posted April 8, 2025 I love it when a plan comes together! Fully operational below dcoe throttle body actuator for DBW ITB. Mostly hidden! Quote Link to comment Share on other sites More sharing options...

Derek Posted April 15, 2025 Share Posted April 15, 2025 Man that is so cool. Not as cool as a DOHC though. 😀 I'm for sure going to do this mod at some point especially after seeing how responsive it is. Great job! Quote Link to comment Share on other sites More sharing options...

DuffyMahoney Posted April 18, 2025 Author Share Posted April 18, 2025 Here is something fun/ silly I have been thinking of and finally made. It’s a remote oil pressure distribution block made to look like the stock 240z brake prop valve. I previously had a steel T In the block, that broke off and then when I was using an easy out I cracked my stock block bung. I said never again! 3D metal printing is neat stuff. I had it tumbled to look even more cast. I run stock gauges and my ecu needs its own signal. This location allows stock wiring to also work.

A to Z Posted April 23, 2025 Share Posted April 23, 2025 very nice. You don't happen to make a vacuum line distribution block do you? I have 3 items needing vacuum supply, and they don't like T's in the line. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted May 1, 2025 Author Share Posted May 1, 2025 I got my Datsun Z Car Series Oil Sending Unit Relocation / Remote Block done! I have only one for sale now, but more are on order. I am pretty proud of this design. Three outlet remote oil sending unit block. Metal 3D printed out of aluminum to look stock and mimics the 240z, 260z and 280z brake proportioning block design. Block has 3 outlets, all are 1/8 NPT. Comes with a custom length -3AN hose and one 1/8 NPT -3AN fitting and either a 1/8 BSPT or 1/8 NPT for the engine block side of the hose. Stock sending unit on a 240z is BSPT, this will require a NPT sending unit like this. [https://zcardepot.com/products/oil-pressure-gauge-sender-240z-260z-280z-70-77?variant=32184292737137](https://zcardepot.com/products/oil-pressure-gauge-sender-240z-260z-280z-70-77?variant=32184292737137) No sending units come with this order. Pictures of sending units are just for reference.

DuffyMahoney Posted October 8, 2025 Author Share Posted October 8, 2025 Working on PCV again, I am going to try for the exhaust. My basic plan is, valve cover to stock pcv valve, to a catch can, then block to the catch can, catch can to the exhaust. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted December 1, 2025 Author Share Posted December 1, 2025 A fun z video I just was sent. It has my R35 coil bracket on it and has over a 1/4 million views! How cool is that. Quote Link to comment Share on other sites More sharing options...
cgsheen Posted December 10, 2025 Share Posted December 10, 2025 I bought the same parts to do DBW months ago - my AEM Infinity ECU supports it as does the RusEFI ECU that I'm also playing with. Got harnesses built, just haven't installed the hardware - so that video is going to be very helpful. Quote Link to comment Share on other sites More sharing options...

MONZTER Posted Saturday at 07:18 PM Share Posted Saturday at 07:18 PM Looks nice, Im guessing 260hp at 6500 to 7000k Do you plan on dyno testing it? Seems like it will be a super fun street car. Realy clean but not so over the top that you cant drive it everyday and enjoy it. Looking forward to more. 1 Quote Link to comment Share on other sites More sharing options...
