So what i learned is the front drive unit will not fit in the factory intended orientation. I should have done a better job measuring it all before committing to it. The firewall, antilock brake module steering shaft etc.. didnt allow in relation to where the wheels hubs/cv are. It was installed in reverse orientation in which i was ok with. But closer look of the mounting points I wasnt thrilled about, also it sits taller with its 60 degree or so angle it takes up a lot of usable space leaving me limited options for battery space.
So i now plan to use a small rear drive unit in the front of the car. It will also be installed in reverse orientation and I will do something to the oil pump as needed and or run external pump. But i dont wan this to turn into a debate about the bearings and running them in reverse..
Ok , I bought a lifting kart to help move, position and lift the rear drive unit. I measured and centered drive unit so that the shafts are close to equal length as possible. Here is what it looks like in the engine bay.
What I’m having trouble with is should I do tubular and the overall design . I searched and looked around what some people did in this forum and on youtube etc.. Examples the rear wheel drive CRX build thread, Tesla Bimmer ... I became aware of Send Cut Send and Fusion 360 Im trying to figure out how to use.
So I am thinking of doing something like the Tesla Bimmer. I’m using cardboard to shape things. Take photo to use as canvas in fusion 360 size it up and trace most of it and make appropriate edits.
There will be two of these plates "boxed up”. Also a “C” clamp like bracket to weld on the frame rail and then this will be welded on that. I’m thinking of 11 Gauge Chromoly. The frame rail i believe is 16 gauge. So I will need to be careful welding different gauge materials. This is just the start, i will then make a bracket for the side support. And other mount bracket that will bolt to the subframe points over the steering rack using same bolt spots. They look strong enough to support.
Another option is instead of that front plate bracket at the front, i can use a tubular design for the front mount. The Evo has a front center member/brace. It bolts and runs from under the subframe to the front chassis bottom support. Normally the transmission would have mounted there as a front roll support. This is not my car but another EVO to show as an example. What you all think ? Issue with this is , the bar would be slightly to the driver side and not directly under the motor mount. I dont know how well it would be to support if I used chromoly tubing and got a cheap mechanical harborfright tube bender to make a slight S bend . I would say around 3-4” of an S bend.
Think of the below transmission as the drive unit. Only that the motor mount on the drive unit will be to the left/passenger side of the brace bracket unless i made an S bend.
