Hey guys i recently turboed my aw11 mr2. The problem is the exhaust manifold sits very close to the old heat shielding thats on the firewall currently, and due to the heat of it it has made it brittle and it is gradually falling away. What options do i have as far as this goes? or what would be the best?

You could get the manifold and turbo housing HPC coated. Not cheap but very effective at keeping the heat in. Looks good too!

Well you did ask "what would be best", not "what would be cheapest". 
As above, a quick and easy solution is a metal heat shield. If you're really cheap you can go to the wreckers and look for something that might fit. A lot of cars have heat shields above the catalytic converter, so you might be able to adapt something like that.

at uni recently we got some large sheets of woven ceramic matting to use for some of our furnaces...
i can't remember what it was made from (but can find out) but it is meant to be good for 1200-1300C (compared to the exhaust wrap which melts around 600C).
we got mats that were about 1m wide and abotu 2m in length... and is very flexible...
i'll find out what it was..

the 'heat shield' thats currently there isnt a metal shield, its more insulation similiar to that thats on the bottom of most normal cars bonnets. Yeah that would be great if you could find out old corrolla. Im thinking most of the damage thats currently there on the heatshield happened when it was on the dyno, with hardly any airflow.

yeh i was thinking something similar for my turbo conversion, the turbo sits just above the starter motor which couldnt be too good for it, and theres notmuch room for shielding, which also means not much distance for the heat to travel to it haha.

just as a quick fix, i put some fire resistant fibre cloth inbetween the firewall and exhaust manifold.
