6A13TT Intake plenum, aftermarket?
SO I've been looking around for the last 4 or 5 months and failed to find much after market stuff for our 8G vr4's (I'm sure a frustration almost everyone here has).
Specifically, a different air intake plenum, to make servicing spark plugs a 2 minute job instead of an hour job, replace lifters easily etc, more accessibility.
I've been looking into making my own, read up about the affect of the length of the runs, the basic shape and volume of the plenum itself to avoid that pressure wave phenomenon, and I've come up with a design like this.

This is only a rough as i took a tape measure to an installed engine, but it should be feasible and able to clear everything.
If I was to make this (I work for a manufacturing company) or something similar once i have all the dimensions, Would anyone else be keen?

Are you replacing the plenum chamber and the inlet manifold?
It looks like you are trying to do this, if so it is much, much, more work than just replacing the plenum on it's own.
I did quite a bit of research on the subject a good few months ago, and you have to really careful you get you non turbo and turbo info separated as the theory is completely different.
I looked into doing a mock up in plastic to do a test fit and possible final solution deepening on strength and heat resistance.
But space got the better of me and I lost interest as I now have other issues to sort out before I tackle anything new.
One of the issues is space, you would really need to remove the original air box and MAF to make it fit, so a MAP sensor conversion would be needed really just for space.
