easiest brake booster to modify

[Mr.SWISS]

$50 for booster and master off CList. Just need to find a 91 735i, same PN as the ix. Clevis is all you need after that to the tone of $6.

944 booster - $37 shipped off ebay. 10 minutes to modify and done

Wow a post every week about this it seems.You are doing an engine swap the booster is one of the easiest things to do.I used 944 and simply threaded the rod a little some more ,pretty much a no brainer and seems much easierer and cleaner then drilling new holes and getting a new res and mc.Not to mention paid $25 dollars and brakes are great.

But with the stock booster you just need to move it over not get a new res and mc, right?

Where did you find said item? All I see is new ones, and 1 for 58$ shipped which doesn't say if it's ATE or Girling.

Edit: I guess this is somehow confusing for some people but you can use your stock res and mc with the 944 booster, just make sure it's the ATE brand. The 944 came with 2 different boosters.

The only diff between the ATE and the Girling is the shaft size is 12 necked to 10 for threads on Girling and the ATE is 10 all the way. Just as a heads up.

But if you get the girling, it kinda defeats the "easiest to mod" factor lol

here's a 944 turbo ATE booster for $49.95 plus $14.95 shipping...although it has a "best offer" on it. Its the same one I have, just needs the rod threaded down further. I also used my stock master cylinder and reservoir. No clearance issues at all...and all 4 studs are bolted!!! Not 3 like the stock slide over method

IX Booster. Drops right in and you just shave a few fins.

Or the 7 series one which is the same as an IX. Thats what I used.

The 320I booster is EASY. Shorten the rod and retap!

Shorten, reduce the diameter of, and then rethread. Not hard, but not the easiest for most weekend wrenchers either.

are there any modifcations that go with using the stock booster besides drilling different holes and perhaps shaving a little off the IM?

Well I moved mine over 1/2" like the thread on e30 tech said and I ran into some problems, the brake pedal assembly gets in the way and I kinda hacked out a little slot so I can fit the nut on, and the securing pin wouldn't squeeze onto the brake pedal because of the misalignment, I simply bent the bracket on the brake pedal and all is well. I advise you to measure twice cut once, I had the worst time doing this and would have rather bought a new booster.
