I am going ahead with the build regardless of what some people say. What I am looking for is useful criticism like "add a brace there" or "I would do it like this" sort of thing.
Gabytech all you have told me is not to do the swap and how much knowledge I lack. The reason I started this thread was to figure out how to clear the subframe. I clearly couldn't cut it in half like you said and you were right all stability was lost. So without the subframe there was no need for the firewall. The struts would no longer be used after I got the new front end. I know the cage will not pass tech I am going to have the cage re-welded at all the points to ensure I have good welds for piece of mind.
RECARO Presents "Devil's Playground." We head to Lewisville, Texas to meet with the Evolution Dynamics team who drove the infamous Mitsubishi Evo during this year's Pikes Peak International Hill Climb and had one of the most horrific crashes that became a YouTube sensation after both drivers survived and walked away unscathed. Driver Jeremy Foley, co-pilot Yuri Kouznetsov, and Car Builder Kevin Dubois recap the hill climb and explain why it's so important to have the right safety equipment.

Eventhough its a promotional Recaro safety video, they also walked unharmed thanks to the well fabricated roll cage and chassis, a text book example why you don't amateur diy fab safety features in a race car....
If i were to do something like that the framework would have been done differently, using 1" and 2" round tubing (or all 2"), something like this:You must be logged in to view this image or video.
(Credit for model goes to original maker, i only modified it)
Please note that although the framework gives structure strength to handle extra weight/power, car's original body is still there and provides rigidity to entire structure. Basically what being done here is an 8-point roll cage being built, but instead of connecting to the car right before firewall, it connects to new front axle. Also cross-braces underneath provide rigidity to cope with high torque of new motor. Round tubing is chosen because it is stronger than square since square already has nice places for a kink/bend to start: the corners.
(Disclaimer: i am not a professional engineer/roll cage fabricator and am not liable for any damages or injuries that may arise from using of this design. Please contact a professional for professional advice.)
