[@austinriggs5502]

Us rx7 guys run master cylinders and boosters from either a turbo 2 or an old 626 when doing 4 piston swaps or big brake stuff because they have a larger bore and are a direct swap.

[@3drifterboy]

Bigger brakes like the mustang brakes definitely require a larger master cylinder. Larger pistons in the caliper require more fluid to move the same distance. Otherwise they will always feel spongy.

[@mixxedboyybuilds8273]

Turbo 2 or 626 master is bigger & a direct swap.

[@paulezay3599]

Dude the mazda is going to be a straight ripper

[@chicagovasko]

💯

Oh ya let’s get this kid over 100 K before he goes back to Colorado. 😎

[@rsharney1111]

I appreciate your work ethic and detail. God rewards people like you.

[@parl9731]

This thing is soo clean! I'm hooked on the look of the wides all tucked under there so perfectly. Can't wait to see this thing rip again!

[@diyracing3049]

I ran into a very similar problem with the brakes. You need a master cylinder that moves more volume. I had to go with a strange large bore master,problem solved. There's a video on my channel explaining it also. Thanks for the good content.

[@206sea]

I love the flammable bottle as a hand rest! Good touch!

[@make-it-work4u]

It looks like condensation from the bov Hot air into cold aluminum will give some water until its warm. Thats my 2 cents

[@lilmike1780]

Soooo glad it’s your rides turn, always amazing work

[@kevinmack56]

Cant wait for the run back with Kyle

[@louisp6384]

Just appreciate the fact he takes Lucy with him on trips 🐕 keep up the good work!

[@dpgarage4501]

Awesome to see this getting so close! Idk about the gas pedal spacer though man, you should probably add some additional bracing.

[@ackilbits]

I'm digging all these uploads you been puting out bro 🤟

[@alltheboost5363]

My best guess is that it's from condensation coming from the intercooler. your bov is right there especially if that was the first time you got to up in boost hard. I know there's been times where my car has been shut off during the heat of the day and then fired up first thing in the morning... let it warm up for a minute or two and then rev'ed it up and it'll blow a Mist when the law valve opens.

[@tymills6170]

Manual brakes for sure! Glad to see it up and running, good on ya!

[@blaznmax8877]

You never realize how hard u mash the throttle pedal. Until it snaps .. put some side braces on it

[@jamesmcivor340]

Contents been great lately, looking forward to your (beautiful) rx7 making competitive passes

[@Kevin-zo6nz]

You have mustang brakes yes make the switch, the diameter of the shaft will be much bigger, huge difference in pedal feel and response

[@chicagovasko]

Definitely need brakes. 😁

[@Tiny6868]

Yes. Need the bigger master. The manual conversion by UPR is awesome

[@EdwardAlcala]

Where’s my dawg at?

[@Manvrick]

I'm excited to see this thing coming together. Manual brakes all the way.

[@nick.4.]

super excited for you bro! build is beautiful came along way!

[@johnnybodangus2529]

Looking and sounding great! Ditch the booster it's a race car!

[@BEYTEK]

Man im sooo buzzing for this!!

[@fast97z24]

I was today years old when I realized what the Tig in Metigulous meant. I'm kind of a dip sometimes.

Stoked for you. Can't wait to see it at the track. Been watching since you got the car

[@nocoasthero1204]

I’m betting Rob Dahm isn’t that hyped on this but I am!

[@imdabeast100]

I think he’d admire the craftsmanship at very least

[@kevintibbetts5249]

Very excited for you man, long time coming this

[@cornfedwrx]

Rx7 lookin mint 💯

[@stoker20]

Everything is coming together like a work or Art!! Let's Goooooo!

[@CraaaigV302]

Car sounds so sick tho good shit

[@mountainsgarage]

Buy a 1987 Dodge Ram Van Master Cylinder, about $35 new no core. Don’t forget driveshaft containment and transmission safety shields, you have done such a nice job!

[@mixxedboyybuilds8273]

Turbo 2 or 626 master is a common swap, bigger, & bolts right up

[@BassManBobBassCovers]

Holy crap that's a lot of fab work! Looks sick doe!

[@RiptRome]

Gratz bro it’s been a long road getting close.

[@twadam5218]

Re: the brakes - call and talk to Willwood. Not saying you need to buy there stuff, but they were very informative with piston surface area vs. master bore size and brake pedal pivot ratio.

[@MonkeyFabGarage]

I had a couple times When I got the cheap pads and the brakes just felt spongy. I had it happen on the Phoenix. I just changed the pads to a nice set of hawk pads. Much better

[@turbomonza1561]

Love finally seeing the car move around. I know it’s hard to stay motivated but man you do killer work maybe after I break my 8.50 cert I’ll have to trailer my car from Cali to you and get some love. Think if you had a buddy or shop partner around it be easier to stay focused and bumped love your craftsmanship and keep up the good work!!! And I hope I’m not alone I’m thinking when you get back home hang the go pro up on the wall and film what your doing with small clips of going over before and after in between what your working on. Definently need more content

[@ThePeoplesLlama]

Always clean

[@chucktaylor7643]

Sounds good, mr2 better watch out! Can't wait for that race

[@88_turbo_fox73]

Good job bud like your work

Ya Boi the quality of your work is impeccable 👌 can't wait to see you and Kyle rip up the track

Who you got? 😁

Dude your fab work is beautiful. I would hang pics of that engine bay all over my walls. That's my favorite kind of art

[@davejames2015]

Check booster for vaccume leaks, also make sure it's check valve is working

[@MegaSpool]

Do you have a dump valve? I have a similar setup with a VS 88/103. I’ve been leaving on 15. With my dump valve closing at 10psi I can get mine up to 15 in about 4 seconds without having to pull any extra timing to get it to build boost.

[@M3rVsT4H]

No point guessing about brakes.. Hydraulics is pretty much just maths. Find someone who knows how to calculate the optimal bore size for your setup and then go shopping for that.

[@eaar516]

I'm doing a similar build except its in a 88 toyota supra! Going single 88mm turbo as well. Your build looks Awsome nice work man!

[@okobojian1860]

Ditch the rx7 brakes. And get this thing so it will stop 🛑 might be handy if it goes real fast. 🤣

[@crazydog2580]

id switch just makes sense

[@bryduhbikeguy]

Little bit of Aerosmith leaked outta my brain with the wristbrace scene."Livin On The Edge"....Great job on the ride.Sounds mean and ready.

[@20b3rotordream]

Definitely go with a manual brake setup and with the added brake size you need a bigger bore master to compensate for more line composite. Just my 2 cents.

[@matthewhannon2509]

my guess, and thats all it is, is you still have some air in the lines or a small leak somewhere, I dont think the mustang brakes would make that much of a difference.

[@emmanuelmeris5841]

Nice work H. How about a third leg out to the inner wheel arch, to triangulate the gas pedal mount? Should take the wiggle out of the mount for no extra weight really.

[@joehall2092]

LUV THAT SOUND 💓 CAN'T WAIT TO SEE IT FLY ON THE ROAD OR TRACK 👣HURRY

[@cryptkeepervi]

Exhaust looks great like that

[@derekg2132]

My mustang makes a humming type noise only when I drove it though ended up being the rear end gears but sounded like yours but not at idle just driving. I thought you said florida for a month. Humming type noise can be many thing air escaping somewhere exhaust leak anything. Like I said mine was driving was rear end

[@bigcaputo09]

I can't wait to see you run down the track with this!! It's Super sick!! Get a bigger bore master cylinder for the brakes!!

[@rj_boostedz2897]

Please post a video on how you setup useing the bump as boost scramble if you can please thanks man

[@realmearthheaven6576]

Yea do the mustang brake stuff. I’m hype to see it rippin

[@route222FAQ]

Question, are you self taught welding or did you go to a welding school? Your welds are crazy good!!!

[@herbiederby3394]

I'll say mustang brake set up go for it...the work is amazing 💯 % and continues but all worth it at the end... be well 🤙🙏

[@Brother2Jis_27s4]

Depending on what you find is wrong with the brakes, realistically if you have all mustang stuff doesn't entirely mean you have to upgrade your master too. I've seen some oddball combos work and other ones that seem like they'd be ok, aren't. See what's up with your brake issue and if you dont care to spend a few bucks on that then do it. Only if its going to fix it 🤙

[@teunex]

Looks so much better with these rear rims!! with the hood it will be so sweet, maybe get some air on the front to lower it for shows ;P

[@keanudeeter-combs4018]

Add a support piece under petal bar. Don't want wiggle at 170mph when you have it pinned.

[@brocklowe118]

Fuck Yeah!!! Been waiting

[@QuickSiR]

Nice choo choo train you got there. 😋

[@josephbeebe6873]

Where do you get the purple a n fittings from?

[@Forever_Luke]

How much cash do you charge for your k series manifold you made for kyles red mr2

[@2raw781]

Sheeesh 🔥

[@CraaaigV302]

Yea I'd ditch the rx7 master ND go manual mustang it's prolly to small anyway because the stock brakes r super tiny on them cars like real small

[@jessehurdjr1037]

U doing it u have mad it brother

[@micheldiaz6912]

Good job...

[@potenitro8796]

Check out the chase bays manual conversion kit i have it and it works great everything bolts up with nice quality parts

[@nickyboi7964]

I hope it goes in the dyno soon with Dr Tune em all

[@dakotaharbert935]

Hell yeah!!

[@FangOfTruth]

Your in Florida. It could have been condensation that got cleared out.

[@coreyabraham3112]

Definitely get those things swap out bigger as always going to be better And definitely find some billet

[@RANDIMHAVOC2011]

Match it all up bro.

[@erickholm9563]

Definitely make the swap to mustang booster. The car is looking great!

That turbo is so quiet when spooling up. The G series garrets sound like a dam turbo jet engine 😂

[@chicagovasko]

Hayden is it true you mostly weld with your eyes shut if so all them welds made blind thats talent and smart.

[@thewraith6360]

Check the master cylinder bore size vs the SN95 master. More than likely the Rx7 stuff is too small of a bore.

[@lastmanstanding5117]

Nice!

I would definitely upgrade the master cylinder

[@paulgeorge4976]

U need to make sure to bed the front brakes in so drive it for 5 minutes let them cool down then do it again if the disc are solid it takes a good 10 minutes then cool down

[@zekialfreido]

I'll tell ya stock mustang front brakes are basically like having line lock

[@TeamDPerformance]

Strange master cylinder set up

[@BadHorsie2]

Put a brace from the floor to the gas pedal bracket.

[@tylerrobertst-rob1731]

Go on and go manual brakes, you'll end up doing it in the future anyway. Either get a mustang master or just go on with a willwood. I got like $220 in mine works great

[@biggrigg938]

remove the residual valves from the rx7 brake master in nz we run twin 4piston calipers with stock master no probs
