GOAL: 

The goal of this project is to design and manufacture a L-Series EFI manifold that will deliver better performance and give the engine an updated and clean look.  The project will include a Manifold, Fuel Rail, and Throttle Cable Conversion.  The manifold will be designed to work with an aftermarket throttle body and the fuel rail designed to interchange between our manifold and the stock one.

 DESIGN:

An N42 intake manifold (early 280z, no EGR) will be used as a baseline for performance and packaging. The manifold and plenum shape will be used for baseline CFD data which will be compared to new design iterations. 

To get the project started and transfer the geometry into CAD the N42 intake was laser scanned.  This model will be used as a reference for packaging and provide measurements for the flange, injector bosses, and other details.   The outside surface will also be used to estimate the interior wetted surface and used for CFD.

This project is in the early stages with no definite timeline for completion at this date.  I will update this page as progress is made.  Please email me if you have interest in this project or have some ideas to add  I always like receiving input and feedback.
