Ok . i did a search and didn't find anything helpful. I am going to be installing a greddy turbo setup on my 88 crx this weekend. I am going to be using a walbro 255 intake fuel pump. I have read that if I use a 12:1 FMU that the 255 pump can't supply enough fuel for that ratio. Do you know if this is correct or not, or do you know which I should be using. The kit is the old Greddy kit with the black box, with the T3 turbo ..
Thanks in advance

255 intank is still way better than stock pump.
But, as many times said -> get an inline... as it can supply fuel at much higher pressures.

I know that the 255 in much better and that it would be even better to get a big inline, but my question is what ratio FMU should I get for a the T3 turbo that comes with the old greddy kit? Thanks

Most will say 12:1 ... I use 10:1 on my setup.. but on the other hand I have D14 engine which is somewhat smaller....
