BEEBANI Posted May 16, 2008 Report Share Posted May 16, 2008 It will not fit, but you can make it fit very easily. The original will not work for 4-wheel discs. Quote Link to comment
]2eDeYe Posted May 16, 2008 Report Share Posted May 16, 2008 Harbody one is designed for front disc/rear drum ;) Quote Link to comment
kiznook Posted May 16, 2008 Report Share Posted May 16, 2008 Hardbody MC will also work for front/rear disc. Quote Link to comment
project620 Posted May 16, 2008 Author Report Share Posted May 16, 2008 will it be hard to MAKE it fit??? or wat other kind of master cylinder can i use? a 240sx? Quote Link to comment
BEEBANI Posted May 16, 2008 Report Share Posted May 16, 2008 look at my build thread (in my siggy) about the 6th or 7th page shows how I mounted the 720 master/booster in my truck. Wasn't very hard at all. Quote Link to comment
]2eDeYe Posted May 16, 2008 Report Share Posted May 16, 2008 Hardbody MC will also work for front/rear disc. Really? I would like to know more :) Quote Link to comment
BEEBANI Posted May 16, 2008 Report Share Posted May 16, 2008 Steve, I'm running the '85 720 booster/m/c on my truck with front/rear discs and it works great! Quote Link to comment
project620 Posted May 17, 2008 Author Report Share Posted May 17, 2008 how about a master clylinder and booster from a hardbody?????? Quote Link to comment
]2eDeYe Posted May 17, 2008 Report Share Posted May 17, 2008 I believe the answer is 'Yes' with some work ;) Quote Link to comment
project620 Posted May 17, 2008 Author Report Share Posted May 17, 2008 or will the 240sx master cylinder and booter work better. cause i think they are the same thing. Quote Link to comment
]2eDeYe Posted May 17, 2008 Report Share Posted May 17, 2008 You could find out for sure by cross referencing the part number. Quote Link to comment
yello620 Posted May 17, 2008 Report Share Posted May 17, 2008 Bolt-on option to your factory booster. Use a 15/16" bore master from the 280zx. This car came factory with the four wheel discs. Jason Quote Link to comment
project620 Posted May 17, 2008 Author Report Share Posted May 17, 2008 i will look at the 280sx. but wat year? Quote Link to comment
SHADY280 Posted May 17, 2008 Report Share Posted May 17, 2008 79-83. there are 2 different styles, one went from 79-80.5 the other the rest, specify bore size. and its 280ZX! hahaha Quote Link to comment
kiznook Posted May 17, 2008 Report Share Posted May 17, 2008 We've got a guy here with a 4x4 hardbody that did a disc brake pathfinder LSD rear end. Stock MC works fine. Quote Link to comment
project620 Posted May 25, 2008 Author Report Share Posted May 25, 2008 will the 280zx booster also work fine??? Quote Link to comment
moparvwfreak Posted May 25, 2008 Report Share Posted May 25, 2008 yeah i was gonna say my pathfinder has 4 wheel disk. and its basically a pathfinder with 4drs and a welded on canopy. Quote Link to comment
datzenmike Posted May 25, 2008 Report Share Posted May 25, 2008 I've looked at this and there is no more room beside the stock booster on a 620. Anything larger diameter will hit the clutch master or the steering column just below. The 720 trucks solved this by extending the booster out on a pedestal away from the firewall. This worked on the 720 because they have the NAPS motors without an intake and carb on the drivers side to get in the way. The inner fender is also 'dinged in' for clearance. I looked at 280zx and S-11 boosters and they are too big a diameter to fit. Or fit easily. Quote Link to comment
project620 Posted May 26, 2008 Author Report Share Posted May 26, 2008 well i wont have to worry about the intake and carb being to on the driver side cause i will have a KA24E in it. Quote Link to comment
