here's mine.
89 vert.
peeled off the rubberized sound deadening material and went at it with a 8lbs sledge and ball peen hammer.
I plan on recovering it with a thin film of somesort or simply re-shooting it with paint before I put the engine back in permanently.

I didn't need to modify the driver's side firewall at all but pushed in the passenger side a lot both behind the head and below it as well to create plenty of clearance for long tube headers. I used Otis B35 mounts in the furthest back of the two mounting holes. I ended up removing the insulation from the cowl cover and I covered the modified firewall area with stick on shiny aluminum faced heat shield that is thinner than the factory sound deadening. I have a good amount of clearance with this setup but I'm not running A/C or a turbo.Never argue with stupid people, they will drag you down to their level and beat you with experience. -Mark TwainComment

Running e30.de mounts in P3, I only needed the most minor of mods with the B35. The engine dropped in with just the bulkhead insulation removed, and then I gave it a small hit near the starter where it barely touched. Then I pushed the bulkhead back with a bar about 3mm for clearance at the back of the head.
I an running the Getrag 240 box though, which might make a difference for gearbox clearance - the 240 is tiny.
If you happen to bash the firewall on a RHD car just remember that there's a long brake linkage to think about back there too!Comment
