ok i have a 90 civic si, and a donor 91 tegra da. i'm swapping the brakes over tomorrow. i have already grabbed the 4040 proportioning valvle off the da and put it on the civic. do i have to swap the brake booster and the master cylinder? i was going to just swap the master cylinder due to it's larger size but when i got to looking i saw it wouldn't fit. Honda BB Tegra BB I have a step by step on how to do the swap and what to remove REAR DISK BRAKE CONVERSION w/pics - Honda-Tech , i'm actually going to remove the gas tank on the integra since it has no title and i'm scrapping it. I will not be pulling the tank on the honda. Put some penetrating oil on my bolts tonight so it will be easier tomorrow. I have hear on here that i can use the master cylinder from a 88-91 4 door so i'm going to go look for one tomorrow. Someone said i can use the front suspension also, but i have coilovers on my ef shell, will i still be able to use them with the da front suspension? Also, they say i will have to use another tie rod? Any ideas. Thanks all.
