brake booster & master cylinder questions (swapping)

[pihlen]

Hi,

I´ve read that people put the Porsche 944 brake booster on E21 and as I understand it they fit with the original E21 master cyl inside? (but u need to threat it a bit more with a die)

I also wonder if the master cyl from the E12 fits right onto the E21 booster (and therefore, in that case, also fits the porsche 944 booster?) ?

I'm working on an engine swap and would like to save space with the porsche booster but would like the bigger diameter master cyl from the E12 and I´m wondering if this combination is relatively easy to bolt on to an E21?

Any experiences?
