hi, i was wondering if a 00 gsr master cylinder and brake booster will bolt right on a 99 civic ex without any modifications?

You need to replace the flare nut on the line that goes into the side of the MC with a 12mm one. You may also need to bend the line that goes into the front of the MC to get it to line up right. Or, you can convert the MC lines to stainless w/ AN fittings.

 

i'd rather get the stainless steel lines. where can i get some from do u know?

I made my own out of Earl's -3 stainless braided brake line and hose ends. I used a 12mm to AN adapter for the side of the MC, and a 10mm adapter for the front. I have ABS, so I did this for the lines from the MC to the ABS modulator, which also used the same 10mm adapters as the MC. If you don't have ABS, then your MC lines will probably run to your proportioning valve, which should also use the same 10mm brake adapters.

I used these parts from anplumbing.com:

592032 Steel Brake Adapter 2 per pkg. 9.27
600103 Speed-Seal Straight Hose End. STEEL zinc plated (Use Speed-Flex Hose) 6.04
604503 Speed-Seal Adj.Low profile 45 Steel hose End (Use Speed-Flex Hose) 18.68
608903 Speed-Seal Non-Adj. Low profile 90 Deg Steel hose End (Use Speed-Flex Hose) 15.99
612103 Speed-Seal Adj. Tube 120 Deg Steel hose End (Use Speed-Flex Hose) 17.81
989443 A.N. Reducer(o-ring seal) 7.24
600003 Speed-Flex Hose, -3 for brake systems (Teflon Liner) 2.97
9919BFE Metric thread male to AN adapter male. 6.90
600103 Speed-Seal Straight Hose End. STEEL zinc plated (Use Speed-Flex Hose) 5.25
610003 10 ft -3 Speed-Flex Hose, -3 for brake systems (Teflon Liner) 27.95

The hose ends listed above are for reference, you should take a look at your setup to determine which ones you want to use. A full listing of Speed Seal hose ends can be found here: http://www.anplumbing.com/shop/index...eed-Seal-Steel

Depending on the angle of the front port on your MC, you may be able to use a 90 degree hose end there, whereas I used a 120 because mine pointed diagonally toward the driver side. If you don't have ABS, then you can use straight hose ends for the proportioning valve ports. Just take a look at your MC and see how you want the lines routed to your proportioning valve to decide which hose ends to use. If you can find a steel 12mm x 1.0 to -3AN brake adapter, I would use that for the side port of the MC. When I did this install, I couldn't find the right adapter, so I had to improvise with a 12mm to -4AN adapter, and a -4 to -3AN reducer. The 12mm to -4AN adapter is the blue piece in the pic below, followed by the steel -4 to -3AN reducer, and the -3AN hose end and line. The -4 to -3AN reducer listed above(989443) was out of stock when I ordered, so I ended up getting a steel reducer(the one above is aluminum) from another vendor. I had some extra hose left over, so I ended up ordering some more -3 hose ends and 10mm adapters to convert my clutch line as well, although B&R Fittings now makes a complete stainless clutch line that runs from the clutch MC to the slave and will save you the hassle of assembling your own. I had some extra fittings and -3 line so I just made my own.

 

I dont know about the booster but a 98spec Integra MC will bolt right up. Mine bolted up perfectly, no bending, no changing fittings

Inspyral is running one of the older MCs

 

Yes, the 98-01 integra Booster + master cylinder will bolt right up to your Civic with NO mod needed. The line might need to be forced A BIT but NOTHING major at all. IT will fit perfectly.

 

thanks yll

 

Yes, it is a 100% direct bolt on in the 99ex. I've done this upgrade myself. You may have to slightly bend the lines because the gsr booster protrudes a bit more than your stock booster.
