hey i need some more help guys.

again with my SR20DET ADM 86 with t28bb...

brake problems this time...running SR turbo front brakes but feels really spongy and have to push hard to work well...

does anyone know if you can use the SR master cylender and/or booster? does anyone know a bolt on or alternate bigger/better brake master cylinder? or something that needs little mods to make the brake better?

any other suggestions welcome...

fuel problems in link below if anyone can help with that?

dude, look/search around the forum more.

Nissan brake masters bolt straight on.

Go get a BM38 off a Silvia or whatever.

are you using the later 4 piston brakes, or the earlier single piston?

the single piston needs no upgrade, if the brakes are spongy its air in the system or another problem.

If the 4 piston brakes are being used, then a master upgrade is a good idea.

r32 gtst brake master non -abs fits with almost no mods. Its a bigger cylinder and will makes the brakes feel stronger.

std 86 master should run s13 brakes fine, mine does, sounds like air in line

As said, you don't need to change the master for those brakes. You either need to bleed them yet again, or possibly they are installed so the bleed nipple is at the bottom, and they will never bleed properly. There you need to switch the calipers from left to right and vie versa, so the bleed nipple is up.

Also, using an R32 master with stock AE86 brakes works fine (though is somewhat pointless), I did it for a while.
