the 1j would be a second car, not a replacement. so 6k mods to mine v 6k 1j
power/weight i would prob have the advantage.
it is true this prob will never get off the paper, but ive been doin heaps oof lookin around on this forum and other opel/vauxhall ones and there is pretty much no advice on what you need or need to do.
so even if this doesnt get anywhere could be helpful for others.
supercharger is new. just made for MR2's.
