Yeah i have a turbo with the number tdo4hl on the compressor. It supposedly came off a 1g. I now from searching that 1g's have td04's but not tdo4hl's. What is the difference? This turbo seems to be from a 3000gt or something. Any ways if they put it on at in 1g era. Would it be better on my at than the 14b is. I am only aimming 4 250-275.
