Sure, but I would weld them if you can. I have a fair amount of info under the "Engine Bay" section on my blog... direct link: Engine Bay | Broadfield's Blog (http://broadfield.wordpress.com/category/toby-broadfields-s13/engine-bay/)

thanks mate. your bay is amazing. If i glass them they still should hold ok shouldnt they?

I agree with the welding. We did a bay like this on an S15 and it turned out amazing. I'm sure the glass would be fine, but I can definitely vouch for the welding.

ok sweet. I jus got some glass then now to get motivated and start

The fiberglass wouldn't hold up as long as welding it. Make sure you really seal it well if you end up glassing it.

Everyone nailed it on the head. Welding is by far the best route. I'd be afraid of glass holding up to heat as well as a good ol' weld would.

It's not the heat I would worry about. It's the constant flexing of the metal and the way in which metal shrinks and expands with temperature vs fiberglass. Very poor way of doing the hole filling.
