is it the banana shaped part on the left side of the right hand arch?
does this fire wall flex/crack usually start up under that rubber strip at the back of the engine bay?
Spot on blackers10 there is actually 3 parts that make up the evo strut to fire wall evo bracing
1 covers the top section of strut top and underneath the #2
2 is the bannana half horse shoe looking plate between 1 & 2.
3 runs from across the fire wall and under the #2 strengthening plate
Ive got a photo somewhere amongst 5gigs worth of Mitsu build up images I'll have to go through which is just the evo reinforcing plates(x3) completely removed from the chassis.
I'll try and find that pic and post it up as its easy to see exactly what parts Mitsu added on the evo, till then you should be able to work it out from the explanation above.
Where the fire wall and the frt apron meet its a very common problem on gsr's converted to evo engine transplants, weird as this is missed by gsr 4g63t converters :unsure:most buy a evo frt cut for the conversion and after they have stripped all the evo parts off it completely, forget or just cant be assed to remove the evo strut/firewall bracing before they throw out the evo frt cut chassis once they have stripped the evo goodness off them.
Welding in the evo supports also halves the amount of flex between the firewall and strut tops very noticeable when jacking up the car from the engine support jacking point (centered under engine)
After these have been welded on to a gsr it doesnt bend/flex as much on the frt strut towers to the firewall = evo goodness in a gsr.
