92 GST Stealing 14B record build

Ya you definatly need to get a thread started with all this good history. You got a cool car that's for sure.

The thread that discusses some of this stuff is pretty stale, so I'll definitely do something new.

Thanks! Talk to you tomorrow after I get the size of the master.

7/8 on the Archer car...

That's a little bit bigger than what I got ahold of. I think that's a pretty standard size down from the factory 1". I was pretty shocked when I flipped mine over and saw 13/16"

Which one is 13/16? Stock or the one from the Mirage?

My stock one is 15/16...

Been talkin' with a friend about the manual brake stuff, here's what another dsmr friend of ours contributed:

Fwd: Chase Bays Brake Booster Eliminator - Universal Chase Bays - ChaseBays.com

7/8 !

...and check page 25 here, apparently the Honda application bolts right up to the 1g dsm:

Ya I ran across that other setup. $200 was outta my range so I really didn't read the info. I guess my first grab of masters was a score.

The one I pulled off my fwd was a 1" bore that looks like yours and the one on the archer car. The one I snatched off the mirage was a 13/16" bore. I wonder what dsms came with what masters. I'm gonna look at all the ones I have sitting around the yard to see what they have.

My 90 Talon is 15/16
Friends 90 Laser RST is 15/16

So, I'm gathering the 92.5 & up might have the 1''.....? IIRC, they went to larger front brakes right?

All things considered, $199 is pretty damn cheap for that setup, however, I think the plate for $75, & whatever master should still be less, and work just as well for slowing down at the strip.

 

[1qkfwd]

Maybe there is a year split or something. All the cars I have are 91 to early 92.

I mean the price they are asking for a new plate and new master is a good deal. Just more than I wanted to spend. I'm sure I could've saved money on a plate but I like the way it looks.

 

[Phil1320]

I'm there's gotta be something like that in effect here. A friend just bought a 92-93 body roller, I'll have him check that out and see what it has.

Ok, I did some more research. It appears that the 7/8 master cylinder is stock OE on the Non Turbo dsm, and, the GVR4. I'm gonna post a link below. Check it out. Under GVR4, it lists the master as '7/8.' And, that part number matches that of the 1.8 & 2.0 NT dsm and NA Galant.

Replacement Parts Catalog

If you look at the turbo models they do list two different masters:

- 3/89-6/90 build date

&

- 7/90-5/93 build date

However, there is no size listed for either application, but based on my 15/16 on my early cars and your 1'' on yours....I'd assume that's it.

My talon's build date is January 1990.

How bout the price though?WTF

Yeah for $75 it will be going on my list after I see how it performs when you actually drive it.

Can you check the size of the master on your car seeing it started out as a non turbo? It might be as simple as just getting the FF plate for you and you're done!

 

[1qkfwd]

Which is weird because my fwd is originally a GS model. So if that's right at some point in time a later year awd master was installed. Cause I pulled off a 1" bore master.

I'll look at my gvr4 to and see what it has as well as my other cars.

Sure enough. Mine is a 1991 Eclipse GS and it has the 7/8" brake master cylinder.

 

[1qkfwd]

Ok heres some numbers for you off the cars I have.
91 auto awd abs car 1"
92 auto awd non abs car 1"
91 5-spd awd abs 15/16"
92 5-spd awd 7/8" (now this is where my GS master made it to when I swapped everything over from one car to another. I also think I converted this car to non abs since my fwd has the 1" bore master. But it was 5-spd so doesnt explain why it had a 1" instead of a 15/16")

So looks like auto cars have 1/16" bigger masters for the 1G. So an Awd car with the booster delete could possibly grab a fwd non abs master and chances are it will be 7/8" and work just fine.

My GVR4 didnt have a master or booster since I was in the process of having the bay painted. Ill have to dig through my parts bin to see if there is another 7/8" master.

 

[goodhart]

I'll check my 93 Talon ES to see what it has. Anyone know what he 1.8 base models came with?

There you go.......and now you have a 7/8 to use if you choose to.

Here's my dilema though: not gonna use a bone yard master cylinder, that's askin for trouble if you ask me. So, I've searched around a little so far. Napa sells it for like $62, plus $33 core, plus a $6 shipping fee, plus tax. So, I'd keep my original. And, with the core that brings the total to about $108 after tax. Plus $75 for the frontline adapter plate, plus shipping. In the end, it's gonna be about $200, so about the same as the wilwood.......


Problem solved! The Chase Bays one may bolt right up, but it will need line modifications and maybe a two way proportioning valve. Stock stuff it is!

 

[1qkfwd]

Thats the nice thing about stock stuff. Better chances of stuff just bolting right up. Plus we have a lot of master choices between the Hyundai's, other model mitsus, and some plymouth stuff. Then if you want a master mounted reservoir or like stock that bolts to the firewall.

If you really wanna save money, just look at the Archer car. Just a steel plate with bolts welded to it. Maybe $20 worth of materials.

I am finally starting to get some small stuff that I ordered for the car. Plus I had a buddy modify my oil pickup. So tonight I get to pull the pan and play around with that and get the pan to pickup clearance where its suppose to be.

Then I really didnt want to but a bunch of locals are having a Dyno day right before I go to the track in Sacramento. So I may try to go and see what kind of power Im making and see what adjustments I can make with the cam gears.

 

[spooling 1g]

So i get the plate and a 7/8's master and i'm good for this swap?

 

[1qkfwd]

Any master you really want to run. Just remember within reason that the bigger the master the more effort its going to take to stop. I have pretty strong legs and probably could've gotten away with a 15/16" master. But I figure I would start with a 13/16" and see how that goes first.

The only other thing you will need to complete the install is a rod to connect to your pedal. I just cut down a long bolt and rounded the end that goes into the master.

Hmmmm.......ok, I'll try to get under the dash in the Archer car and see what they implemented there. Unfortunately, with the cage, it's super tight in there. There's no passenger seat, but there's still a heater core in there as this car ran some endurance races, rain or shine.

 

[SBstar]

Good job Justin, this is a neat modification. I'd love to do it myself, mainly for the weight, and secondly to get rid of the big ugly booster, but since I still drive to the track I'll probably have to add this to the "after trailer" mods list. Thanks for sharing!

You need to get a thread going already on this thing.

Thanks Shane. This really turned out nice. Better than I expected.

Figure I would try to get caught up on soem stuff thats already done to the car. I will fill in those pics as I get other things done to the car. You can see in the pics why the cars so light. Ill let the pics do the talking.

 

[1qkfwd]

Been kinda busy lately. Got a few more things done to the car. Finished up installing bushings in my front control arms. Now the front suspension has minimal movement. In the process now of redoing a few things. Gotta have the car ready in a week or so, that way I can hit the track in two weeks. I'll try to update as I go along. Lookin forward to testing put my new brake mod to.

 

[xxNocturnalxx]

I like the door panels, where did you get the material?

 

[1qkfwd]

I had a local guy make them.

 

[1qkfwd]

Ok so I decided that I wanted to redo the intake and ditch the 2.5" section that came off the turbo and do a full 3". Only problem with that was the way the intercooler piping was, it kinda made things tough. So last min change of the upper pipe and a new ram air intake. I really like the way it is turning out. I also had to move the FPR because it was not mounted to anything and was afraid that the 90 degree fitting holding it to the fuel rail was going to break. So now its mounted to the firewall.

 

[arprez]

liking the updates brother can't wait to see it run

 

[1SloEvo]

Looking good Justin. Hope the car runs well when the track day comes!

 

[1qkfwd]

Thanks guys. I'm so excited to get back to the track. I plan on trying out a bunch of different things with the 14b to find the perfect combo. It's gonna be a fun year.
