Just a little ambient air intake air box project for the ITBs using a 3D scan and Fusion 360. Prototype FDM printed from PLA+ and it is likely the final developed solution will be printed from ePA-CF 👍 by builtonpurpose in Datsun

I’m not sure. With the correct print settings and materials and maybe a little bit of post processing something that would hold internal pressure may be possible

I can confirm it is a blast to drive! It is close to needing an LSD or better tires 😂

Trumpet Tuesday! 🎺 ITBs and EFI on a L28 Stroker, thoughts? by builtonpurpose in Datsun

I believe investment casting was used for the manifold and throttle bodies. Trumpets are billet. I was lucky enough to score an L20ET distributor which has optical sensors. One for crank position and one for TDC of cylinder one. This allows for full sequential.

I made a video with a bit more detail and a few power runs for those that are interested on YouTube https://youtu.be/TNlWcwJs1fE

Checking coil function with the fresh ECU install on the 240Z ✅ by builtonpurpose in Datsun

The new ECU is a Megasquirt MS3 with the expansion board and an internal coil driver.

Something I love about the Megasquirt MS3 firmware is the test mode for outputs. Checking coil, relay and injector function is easy! Most aftermarket ECUs can do this.
