Guys,
Yes, conventional wisdom would be to reuse the original tunnel
with some modifications. But, being strictly an amatuer car
builder, I managed to bugger it up when I cut it out
I thought of fiber glassing a tunnel, but I do think the tunnel
does add to the Alfa structure (albeit very slightly), and I
want some steel between me and the 9000RPM I plan on doing
with the S2000 motor/tranny!!
I was actually pretty impressed with the heftyness of the stock
tunnel, there is some gusseting, and some relatively thick steel.
The tranny mount is very stout, and ties the two lower sills of
the car via a very thick metal plate.
You all inspired me, and last night I bent up a tunnel on the bender
here at my work, and will be making some mods to fit into the new
floors I made. Hopefully I will have some pics next week.
