Mazda RX7 Spirit R build ep. 1 | fullBOOST

Over the past couple of years we’ve covered a few of the many high end Mazda rotary engines that Melbourne performance workshop, Promaz Automotive, pieces together for a variety of street and race applications. This time around we’re going to follow one of the more sought after Mazdas, the FD RX-7 Spirit R during a complete engine overhaul and power up.

Stay tuned for the next part of this build coverage.

[@danielbrealey2924]

Here we go! 🤙 A build really worth watching. NICE 👌

[@TURBOTRISTO]

Can’t wait love these cars

[@bondmcnugget]

What is the restriction? Don't do us bad like this 😭😭😭

[@LS8585]

Great content! Love it!

[@richiebarrow9169]

Really good viewing, no crap comments,simple informative content. Thanks guys

[@nismofreak33]

Could listen/watch Simon all day.

[@pokohuh]

insane to see what really on goes behind these amazing engines. Long live bridgeport

[@DG-oo3jt]

This bloke is an absolute legend.

[@berjohansen]

True

[@kc-nl8zc]

Wow what a eye opener! I've been a mechanic for over 20 years and this is alien technology man lol

[@ImEasyAs]

I think the restriction initially starts before the turbo in the exhaust flange. The exhaust ports have a 51mm diameter (= total exhaust area of 4,085.6mm squared over both ports). It seems the most common exhaust flange are T4 twin scroll, so the total area of exhaust area in the flange is just under 3,692mm squared. This immediately restricts the exhaust area, not taking into account any of Bernoulli's principles with regards to the manifold itself.

[@jrbuch]

Always loved these things. Great looking cars with a unique engine. A girl in my year at high school was always dropped off at school by her dad in a dark green one the SP model with the big spoiler - I thought she had the coolest dad ever.

[@RS-sv3bl]

Once you’ve experienced a Rotary, you never go back. Beautiful stuff. Want!

[@Gooie69]

When you run out of money you do.

[@pittassavvas7512]

Thanks again lads. Amazing how much goes on behind the scenes. Simon would make a great dentist. 😅

[@DTGTDetectingTheGoldenTriangle]

Good workshop promaz they even tuned my 1jz t66 swaped gs300 👌👌

[@MrDOHC1JZ]

Main restriction has to be exhaust for a rotary due to the sheer volume of air the move. And intake would be a close second. Hence who a “1.3L” rotary have such monster turbos

[@vxarea3822]

Such a good video, it feels really "personal" with Simon, the way he talks and stuff. loving it

[@Nangbot8]

agreed! they do a great job with their audio which really captures someone like Simon's temperament.

[@sparkyexe]

Never gets old. Great to see a pro do his thing and take us through a build. Thanks guys

[@mariosnikolaou5212]

Greek team ftw ! Χαιρετισμούς!

[@r1yamahamini]

I owned the most presitine, low K Spirit R.. serial# 1012 If you are the guy thar bought it from me (2014) reading this, well done... You got the bargan of the decade,.....

[@marcelloav]

It’s always good to see and hear a professional at work

[@MyFamilyGathering]

Thankyou very much FULL BOOST. I have loved the FDs when they came into the market years ago and always told myself...."One Day". But at that time being a F250 4x4 owner/daily drive, Like many, one has to educate themselves on Rotary (If your brought up on V8s). This episode, not only was it very educational for me, but inspirational to continue the Journey of Rotary education. PROMAZ AUTOMOTIVE incredible archive of knowledge was astounding. So thank you to them and thank you to you guys for sharing and help educating me.(some of us dinosaurs don't immediately comprehend all facets of a new hard drive technology)

[@moonrockslol9619]

I like it when you guys make these kinda videos

[@vin18m]

Love the nerdy stuff, always top quality content from you guys.

[@crookedFC]

Brilliant video - the transparency is testament to the build quality and workshop.

[@andrew8502]

Awesome episode. great editing. Super interesting. Simon knows his stuff ! Looking forward to ep.2

[@thecookeman]

well done digging up the old video! always great content. The workshop tours and expert knowledge is fantastic. looking forward to ep2 !

[@stephen865]

13:25 that brings back memories that was my cousins car that was a fun night, remember getting dropped off to school in that

[@dmp.performance8635]

Digging this series!

[@NSPOOL]

I like this series already

[@TURBOTRISTO]

I would love an obnoxiously loud N/A 13B bridgy nz style

[@sirsprinter]

Great production lads

[@charlesgalea69]

Thanks for the video today guys.

[@Nangbot8]

Thanks so much, this is the absolute best!

[@blueboygt-r9106]

That's was amazing at RX7 Dude😀

[@peterga3658]

whenever i see rotary builds ... bro amazing ...

[@davidm5867]

Simply awesome

[@yoginandbissoondial7989]

Great video!

[@needmoreboost6369]

Still yet to own a rotary, worked on a couple big turbo streeters that blow my mind! I use a die grinder it’s similar lol

[@user-yz9sy6ng8x]

good stuff

[@yoginandbissoondial7989]

At about 7:55 there is a sign for a company: Saint-Gobain. This company is located in Worcester, Massachusetts, USA. I live not too far but it’s interesting to see the reach of that company around the world based in my home state.

[@fullboost]

Saint-Gobain is over 350 years old. 👍

[@boborosektim]

Simon is my favorite engineer 🇧🇬

[@michaelallen2501]

The restriction on the street is probably the turbocharger itself. Specifically the exhaust housing.

[@spring6meow]

EFR9180 is the answer 🥰

[@ben8629]

That was awesome thanks guys

[@Twigger01]

Wow amazing stuff I bought a RX8 with coolant seal failure I stripped it and rebuild in my garage at home. I did extended ports and smoothing of the intake to do what you guys do would be a dream of mine 👍

[@pp4173]

Did you notice a difference

[@Twigger01]

No, as when I got the car the engine was non running so I didn’t know how it drove beforehand

[@pp4173]

@@Twigger01 I hear from alot of rotor mechanics that it doesn't make a difference

[@Twigger01]

Like I said I wouldn’t know sorry but I did lots of other mods on mine other than the ports my guess is that you would only get 6-7 bhp just ports alone but the engine will be much more responsive

[@pp4173]

@@Twigger01 ok the reason I was asking is because I have my engine apart and it's the only chance I have to port it now but wanted to know if it was worth doing

[@MartinMcMartin]

Good old bendy torque wrench💪💪

[@granthawtree4669]

Sounds like some Barra ghost cams

[@MrJermbob]

Biggest restriction on a street car would be the exhaust 9x out of 10.

[@dandewar8403]

I thought he was talking about intake only??

[@MrJermbob]

He just says lets see if they can work out what the restriction will be on most street cars. Sure hes been fingering the intake port while saying it but if you dyno cars alot. Stick a boost gauge in the down pipe o2 sensor location. You will be amazed what pressure you will see.

[@Skyrexx7]

Ask Simon for me, is it safe to run 1.6 bar boost on 99 octane pump fuel with wmi?

[@sidbobby3233]

So bridge Porting helps with low end talk (allow my spelling)?? 👍👊✌ frm from the UK

[@Slayeranon]

brap brap

[@Scott-ho1sm]

Restriction would be the exhaust?

[@rockbiterhd]

Now that man is the dorito god

[@PUNCHARD800ftlb]

ugh the smell of that gasket goo tho

[@cemturyan2653]

I'm so excited to see the next video. What's the restriction in the engine from factory? Intake runners?

[@Bird-nx5ef]

Port size

[@gav240z]

Throttle bodies?

[@MrJermbob]

Throttle restricts the engine from revving to 100,000rpm.

[@lancecooper4646]

.....the exhaust system that a street car has to run ??

[@joeracer302]

Can compensate a lot for poor intake flow by turning up the boost. If it is N/A it’s a different story, but with a turbo the boosted air will get pushed through restrictive intake, just need open exhaust. Of course, optimizing intake and everything will give more HP, but a lot of cars make good power with stock intake.

[@KalLanPIDT]

What does this special sequence of studding do? codelock for more hp? xD haha! Any decent mechanic will know how to tighten it properly.

[@junit7590]

Braps for days

[@hendrahendra]

The turbo is the restriction.

RE ALL DAY

[@Hulk12397]

Can I please have the car? I don’t have much, but I love that car lol

[@Cetrifuga1945]

Siete riusciti nella vostra ottusità ma con me no io ve lo metto

[@fgdgrddsew2]

i remember when these were like 40k America ruining everything as usual

[@kavaka0068]

Mazda RX-7 is the best body car for future. 1. RE AMEMIYA RX-7 FD3S 2. 2005 Veilside RX-7 Fortune 🤣

[@ErnestoEliasMartinezIV]

I want sale Mazda rx7 touring 93 almost like new 64.000 jdn engine 185 hp not 155hp $40.000 usd

[@clarissafarmer3547]

Shame doing all this work to an engine just to have it leak oil and water for the entire time of it’s very short life

[@Stopthegreed]

That would be a shit engine builder if its leaking oil and water from a fresh rebuild. I've owned several FDs and FCs and never had issue with any of them. The FD I've got now I've had for 8 years now and give the thing death. Doesn't miss a beat.
