anybody think about doing this? i'm seriously considering it! both my rx7 and Z run on premium, so i've decided to ditch the 2jz build i've got going and find me a 83 ld28 and make my own biodiesel. for under a $1/gallon you can't beat that. but, yeah, the point of this thread...will the p90a turbo manifold swap to whatever head may be on the diesel motor? i know absolutely nothing of the ld except for the knowledge of the crank when i was considering the l31et build. i did a search but very very very few results were found concerning biodiesel. anybody and everybody will be of help, thanks again guys.
