Well, i swapped in a LD28 out of a maxima into a 240z of ours, had little to no traction through half of 3rd gear. was a blast, sold it to a customer before i had a chance to turbo it. I think the 4bt would need alot of stiffening to the frame, im already getting cracks in the body of my 72 from drifting and autocross... i never had problems with that when i had a 8 point roll cage in it tho.
