I don't think so, ScottyBobcat had a lot of trouble fitting in a decent sized radiator and fans with his V8 conversion, the length of the 6cyl would be a killer.
for something different why not check out a FD42 ? comes in the atlas trucks. 4cyl, there is a turbo version, no idea on power. weight may still be an issue, not idea on height.
ive measured it... it should fit...just be very tight.. might need to put the radiator in the rear. give me another 12 months and ill tell you how hard it was to do haha
