!!!!!!!!!!!!VERY IMPORTANT!!!!!!!!!!!!!!!!!!

 

I found out the hard way today that the check valve must be built in on the Legacy booster and it is not on the STi. Just go to Napa and purchase a check valve that will fit the hose going to the booster and you should be fine. I havent purchased the check valves yet but will be doing so tomorrow. I was doing a 3rd gear pull at 25psi when I found out about the check valve:)

Just ordered a 2005 STI master cylinder and brake booster for $62 on ebay. Any tips on the installation we should be aware of, such as adjustment of pedal travel or what needs to be removed for access? Thanks in advance.

 

My motor was out so it was easy to install for me:)

Are you going to run twin Stealths? I'm curious how much noise they make. I was going to do a single stealth in-tank and ID1000's if I decide to follow through on fuel mods.

 

I am running twin Aeromotive Stealths and they are not as loud as one Walbro:)

Just a FYI - I finally got the car running again. OMG what a difference the STi MBC/Booster made on my car. It is night and day. No more mushy brakes or parachute effect for me. Great $60 upgrade:)

Sorry, wasn't trying to be a jerk.....I was just trying to explain the problems I have felt with the brake pedal feel.

Same here. With Brembo calipers the stock cylinder works fine and no "squishyness" at all.

 

If you didnt notice it prior to the Brembo setup you won't notice it afterwards. It is more of a pedal feel. Coming from cars that had great pedal feel and no parachute effect when pressing the brakes is what makes the LGT brake pedal noticeable to me and others. Like I said previously, try driving a WRX, Scion xb, Toyota Corolla, VW Jetta, etc...the pedal feel is much better than what we have in the Legacy.

Awesome. I've been really interested in the stealth since it came out, but haven't heard much about them.

 

Don't forget to run 3/4" fuel lines

 

 

LOL, Already ran them:lol: I bet that makes you cringe:)

Yes, running twin stealths after the idea of running one in-tank 1500HP Fuel Labs pump fell through. I know it is overkill and I could of gotten away with twin Walbros. From the people that tested the stealth pump has told me, they are quieter than the walbro pumps. I will let you know in a few days how they are.

Did you have a chance to get the car on the road yet?

 

No, will be back on the road this week or else I am kicking someone in the junk:lol:

Aren't those the higher performance ones that need heating up for "optimal performance"? I used Hawk HPS on my last car, and they worked great.

 

 

I had the HPS pads and swaped them out for the HP+ pads. The problem most of us are talking about happens regardless of temp in the pads. Go drive a car like a Scion xb and then drive your LGT again. The pedal feel and amount of pressure in our cars suck. Our stock brakes are bigger than a standard WRX and on par with a STi but our MBC is smaller than the WRX.

silly question, but all inner and outer bleeders? If so, what kind of pads are you running?

 

 

 

I'm thinking the "MBC" you see is master brake cylinder. So all you should need is the booster and cylinder to make it work.

 

Correct, Hawk HP+

 

MBC = Master Braks Cylinder

Trust me, I bled my system about 5-6X

No, the Imprezza and Legacy rear hubs are different. You will need Spec B axles. I think I paid around $600 new for the pair.

The Brake booster is the same between the WRX and STi. The MBC is bigger on the STi.

Sorry, car is running but was waiting on the dual Aeromotive pumps. They finally came in late last week so we should have it on the road this week.

Front Brembo Calipers, Slotted rotors all the way around, SS Brake Lines, Motul Fluid, Hawk HP+ Pads all the way around, and now the MBC/Booster from the STi.

and pedal feel?

 

any updates to it

 

Like I said in the other thread, my car won't be back up and running until later this week. I will report back after my car is running with pedal feel.

Yup. Many WRX owners just swap in the STi MBC. If you want to play it safe just get both pieces from a STi off of ebay like I did.

Just to update this post, you need the booster from a wrx or STi and the MBC from a STi and it will bolt right in. The STi MBC will not bolt onto the Legacy booster.

Yeah, you need the 5MT NSS and the 6MT reverse switch.

I did the 6spd swap Saturday I used the 5spd neutral safety switch and the reverse switch but my reverse lights don't work anyone have any ideas

 

Are you sure you dont have the harnesses backwards? I had the NSS and Reverse switch backwards and the reverse lights were on when it was in neutral:lol: I didnt know until my wife was following and called me to ask if it was normal for my reverse lights to be on while driving.

What hammerdown said. I drove around for a few weeks witht he wrong NSS in and only got a CEL.

Yeah, I got one from car-parts.com for $100 shipped.

I have the opportunity to pick up an '07 Spec B drivetrain for a pretty good price... How bad will I miss the front diff that the '04-'05 STi has?

 

If you are not tracking your car, probably wont miss it that much.

You needed the driveshaft from a 4EAT wagon. I think that was explained in the first post. That is what I used and never had any problems with my 6MT conversion in my wagon.

 

I used the STI Shifter assmebly with a kartboy short shifter without any problems.
