My friend and I ran into a TDO4 that another friend is selling (Just the slug itself). . My buddy and I want to decide which car can use this, his (has a 97 Nissan Sentra) or my teg. On my search it is said that it is designed only for SOHC not basically for our B series? Is it true? If it is then it means that his car is no use for this also. Is this turbo 2 small? I know that the 3000 GT came with this turbo (twin). Thanks.
