2+2 Replacement Brake Vacuum Booster

[toopy]

I need to check properly after the cars winter layup, but it's highly likely i will need a new booster.

It would appear buying brand new is not an option, everything i can find is remanufactured stock only!
The early boosters are 7" so Im assuming i require a 10" jobbie, and more than likely a 280z example from the US?
Most are core return affairs, but I have seen a Centric 10" for a 280z on ebay that is buy outright.

So who as bought what from where and do they seem to be of acceptable quality?

Hi, Considering the cost of a replacement servo when all said and done, I opted to buy this setup instead.

I haven't yet finished installation, so cannot yet comment upon performance.

If you decide to go with this option, then you will need to contact the supplier and ask for stud pattern to match a 260z as it's different from a 240z

What about a hilux servo ? I'm sure I have seen/read about using one as it's the same size and the OG master cylinder bolts straight up

I've known this system used on a race car (Brian Morris).

Are you going to leave it without a servo or use remote servos?

I will be interested top hear how you go on.

Rob, I'm hoping brake performance is good enough without servo, so my plan at least for now is to go without servo.

The system is 80% installed but I have needed to change my priority to chasing an electrical fault, so I guess it will be another two weeks at least before I get to test the system properly ....... but of course i will let you know how it goes.

Thanks, always good to have options, but that's not really my cup of T

I'm not sure about Hilux but I believe some people have retrofitted a Silvia servo and master cylinder assembly, but then that does have a different bolt pattern so will mean some drilling of the bulkhead.

I have read that also, but IIRC you also need the Toyota 1" MC which looks god awful in my opinion, besides i already have a nice new 7/8th MC.
Also it's not a straight direct fit and may require a little fettling where it goes through the bulk head aperture, I seem to remember the one i read about was for a 280z swap and I don't know yet if the bolt pattern is actually the same as the 240/260 anyway?!

Rockauto do buy outright from the states £120 + tax/shipping

I bought an early 280zx one from Rockauto, which should be a direct replacement, part number 16088062, with shipping and tax, came to approx £190
