So I went to order the 2 pot master cylinder adapter from ECI and was told that the ford 8.8 discs will not operate in manual that they require a power booster. Definitely sucks since I scrounged a 3.55 limited slip disc rear. I've seen threads of others who have done this swap and would like some input. I was told that due to the small pistons it requires higher pressure to move them. I asked about compensating thru the proportioning valve and couldn't get an answer. For those that have done the swap did you stay with manual brakes or add a booster. With an adjustable proportioning valve were you able to get the brakes to operate. Are pedal pressures higher. I'm not looking forward to scrounging for a drum rear. I won't add a power booster to the firewall and don't really want to add one under the floor. I've read plenty of forums from the HAMB to here and nothing really discusses trials and tribulations of have a manual 8.8 disc setup.
Thanks
