Like someone else said already, the swap has been done many times.
The motor is pushed back considerably further back than the original rotary. Relocated battery to trunk, removed any uneccessary weight, ie, ac, emmisions, etc…
It also sits a little lower. Its gonna be even lighter once the aluminum heads go on. Might have to do some more weight distro one the turbo kit goes back on but right now it sits at 51-49.
Its all about the balance of the weight.
This will be my second swapped FC. First one wasn’t nearly as clean but the car still outhandled my S13 at the time. Stock for stock. I know its hard to believe. There’s a certain stigma about domestic motors. (Understandably) but really, the nose heavy issue has been sorted. Even pushing the motor back an inch makes a significant difference
