The bluebirds over here were 1800cc, so i guess SR18DET but im sure, like you say, they had a 2000cc. Its hard to find a good ZX Turbo engine cos there wasnt that many of them and it was such a long time ago, most of them are probably in the scrapyards. On the other hand, with it being less desirable than the GTi-r or 200SX engine, if you come across one, im sure it wouldnt cost much. Heh, never thought of using one of them
