Think ive figured out how to fit the motor in the front under the engine by mounting the steering rack ahead of the front axle insted of the original position behind. have tried to mount it as low as possible but after looking more closely i think the motor may just collide with some of the pieces bracing the upper parts near the engine. I beleive it should only do it when the suspension is fully compressed, so a little bit of re-sterngthening/braced will be needed of the upper lift arms in the area described.
