looking good, really good.
i just recentl learned why i is best to keep the intake nice and straight, and explains why Mad Mike gained some HP on his most recent engine modification and another 500-1000 rpms.
i have seen somewhere before that aluminium centre plates wouldnt hold up to higher rpms as the bearings work themselves loose and on an engine such as yours with all the time and effort into building this bad boy the last thing you want is a bearing wrecking everything.
i take it you cant show us the eshaft? is it something you have designed and made? 3 piece?
did you think to try the engine cooling like mazda did or was that too complex?
looking forward to the progress, the build and the start up
thanks for sharing too

Awesome - Going to be following this one very closely 
Love the new firewall. Engine is a work of art! I hope you have a high quality video camera to capture the sound when she runs

This is just all out crazy! I was completely blown away with your S3 article, but this is going to be on a whole other level! Good luck with it and I am anxious to see this thing come together. Best of luck.
Random, but are you manufacturing your front splitters with '93-'95 fronts for the masses?

Thanks Grant! I didn't photo the eshaft, was always in a hurry. It's a custom 4-piece unit, so trick. I am releasing a video that has a bunch of footage showing most of the internal parts. Stay tuned on it :-)
I was going to do center cooling, but the center bearing feed tube made it too complex. Had to skip it. The external method is rather nice still, so not too big a deal
