Do a write up I'm doing this soonPlanning on using a booster from a 95/96 on my 92. Do I need to use the master cylinder from the same year as the booster or can I use the master cylinder that is in there now?
They're all 1" master cylinders. It's easier to do the whole unit with master cylinder/proportioning valve though.
You'll need master cylinder as well, regardless of what dual diaphragm brake booster you use. The 95-01 XJ master cylinder is much different than the 90-94. Ports are metric bubble, so you'll need new lines. I got premade ones with the metric bubble fittings and flared them for the standard fittings. Worth every bit of hassle.

i would recomend going to a junkyard and pulling the lines and prop valve off of the required donor vechile, as well as the spacer plate under the booster. simplfies the whole install greatly. just be cafe, on the rear port of the propvalve there is a dummy cap used on abs models, this cap needs to be removed and replaced with a non abs model one to allow for the second front line to connect to the valve.
I swapped my 94 abs to 96 non-abs, but the doner was abs. not relizing the valve i had to return to said jy and fetch the missing cap.
simplied teh install greatly, since the lines out off the valve are sae not metric
not booster or master, i wouldn't trust a jy unit. just simply the lines and valve and bracekt. nothing can go wrong with those parts. saved me a huge head ache making by not having to make the metric lines, for which i don't have the tool to do so. i have sae.
As I said above, you have no choice but to change the master cylinder. I have personally done this swap and am 100% certain of it. Use rockauto.com to pull up pictures of the master cylinder and power brake booster from both years and it will be obvious that the are not the same.
