Well there are many 601 versions ...
Including a D23 turbo, all this versions have diff pumps in it.
Of all this pumps the pump in 601D23 turbo is the best cause has 6mil elements able to 70 to 80cc with pump maxed out.
But this is not a big diff, compared to a 7.5mil pump.
I have tuned 2 601's and belive me they hold a 7.5 pump a lot better than most 606. Power improves to double and tq rises a lot. Even with stock turbo. Just need boost increase.
PM if u need or want a biguer pump.
