I am designing a DBW actuator for this DOHC now!

Its now my least favorite looking DOHC, but it's pretty darn cool technology.

Used ITBS seem to be very rare. HKS, I would stay away from the full chinese DCOE ones. KMS takes the chinese bodies and retrofits them with better butterflies and such. https://en.kms.vankronenburg.nl/products/throttle-bodies/bodies/throttlebody-twin Then there are Jenvy EFI Hardware (probably the best designed out) Throttle blades open the opposite way, tapered bore, better throttle blade angles Borla OER(I would stay away from these) ETC.... A common issue with ITB is when the engine is hot on a hot day, they tend to stick slightly open and having them return to idle doesn't work. I believe the bodies expand and cause pinching, but who knows.

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.

Pictures of sending units are just for reference. Link: https://www.m2racing.com/shop/p/datsun-z-car-series-oil-sending-unit-relocation-remote-block

Idle increase while hot is the same issue most of us ITB guys are dealing with, I hope a heat shield fixes it.

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.

I don't have DOHC type funds:)

I love it when a plan comes together! Fully operational below dcoe throttle body actuator for DBW ITB. Mostly hidden!

Gonna have to use the internet for that one then.

Yep, I bought a few.

I was told the subaru shims are identical, i bought from the local dealer.

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.

I was inspired by the FET as well! It gave almost the perfect injector angle. I am not a turbo guy, but very nicely done.

Larry is a good guy and I consider him a friend. He is very talented, we talk a lot about intake design. The up and away aspect looks a lot like my design as well. Super cool stuff!
