super informative! great job

What an over-engineered nightmare

Thanks for the explanation, the music in the beginning was loud and distracting though, you don't need music in your video when you're talking. You don't need music at all really even if you're not talking, just replace it with the sound of your car lol

Thanks man, now my TPS is working perfectly !

Rewatching this video again. So grateful for it. Helps me understand the system.

this was an incredible video. thank you for putting it together!

Love the video!! But my god did it addd to my anxiety since I just got an fd. That's also having a boost isur above 4500 😢

Have you tried reinforcing repairs like those with the melted in metal strips?

21:24 does the actuator move with IGNITON on an off or engine on/off? If its ignition -> how does it operate if the engine isnt creating pressure/vacuum to move the diaphragm? 🤷‍♂ Or is it rest of pressure/vakuum in the chambers?

I just bought an FD with stock twins and once it reach 8psi engine cut

This is a perfect example of what makes youtube and the rx7 community special. Thank you so much for this valuable info! I will definetly be referencing this video a lot while diagnosing my turbo issue! Thank you sir!

Good Stuff!!!!!

Thank you for this! I downloaded this for more review

Oh that UIM looks familiar… are you selling that right now on FB or the forums?

Hey bro. Thanks for the helpful explanations. I’m hoping this video will help me figure my issue. I’m having symptoms similar to LIMP mode. But I don’t have any error codes except air pump relay. I have stock ecu with emissions delete. I can rev to around 5k before it falls flat. If I hold throttle in flat spot, it cuts and on cuts and on continuous. Like limp Ive triple checked solenoids, vacs and electrical. Omp etc.

can we substitute some of these solenoids to modern 3-port MAC solenoids? especially for the exhaust control valve, instead of having 2 solenoids for vacuum and pressure, have a 3 port solenoid plumbed similar to a 2-port external wastegate

God I need to buy an fd. Always been a dream car of mine

How can i check my wastegate actuators by teeing into them? What numbers should i expect to see? Also, where can i tee into to find the absolute raw pressure of the primary turbo, i.e before it gets to any sort of piping where there could be leaks, etc?

Can’t believe I made the Final Cut😂

Was great meeting ya! Awesome cars! Lets drive again soon

Had to be stuck 5000 miles away 😂

Im having a similar problem to the other guy here in the comments. I have a series 8 FD and my problem is as follows. Rev in nuetral: Cant get to +4psi Boost pattern 7-0-0 KOKO Test: CCV rod moves in like normal 6+ times KOKO Test: TCA doesnt necesarily stay in on the Key-on position. Kinda pulses in if you get what I mean. But it reverts back to its normal position though. Is the rod supposed to stay in on the key on position or is it just supposed to pulse? I can get a video up of it if you'd like. It moves in when revving in nuetral though. Check valves are all upgraded to the Viton ones that Dale Clark mentioned. Pressure tank holds pressure Vacuum tank holds vacuum (hissing sound on both) All lines good. All couplers good No signs of smoke on smoke test. All solenoids have been tested and function like they should. (I managed to get the "black box" apart and put in new check valves and test the solenoids lol) CRV and ABV both pop open when tested under a vacuum guage. No hoses are collapsing as i took off the turbo inlet hose temporarily to test for that. My only suspect is the Wastegate and Precontrol Actuators as i havent looked at these yet. The TCA would be the other suspect as something seems off about it as i mentioned earlier. Unless my explanation of it seems normal to you, in that case, i can rule it out. What do you suggest? Would the wastegate and Precontrol actuators cause these issues?

Great footage, Jacob!!! Helluva lineup this year

LMAOO I drove by this saturday morning in my is350 I thought my car too clapped to be near you all so i just drove by and recorded I never seen a single fd rx7 before that day

Fantastic! Big thanks for putting this together. It demystifies the turbo system. The movie version of Dale's book.

This is the best RX-7 vacuum/pressure control system info on TH-cam Universe. Hat off to you Sir!

Thinking of upgrading my oil coolers What size would do for a 13b thats semi pp/street port?

Aww thanks for the tag!

Thank you for coming! Nice line up of Rx7’s 🔥🔥🔥

It looks like it was a great turnout 🔥

Awesome footage! Sad a had a family thing come up the day of (woulda rolled up in the daily anyways). Here’s to the next one 👊

just cool cars there! 🤙🏼

Nice! Funny, most of us had visible exhaust smoke 😂 #earthfriendly

That yellow one though 😍

TE Tuesday and happy Pi day, 3.14

What’s the torque specs on those wheels

two of my dream cars sitting in one spot.

Meanwhile I’m STILL trying to find an oil cooler for my GSL-SE 😢

Thats my dream headache car 😅

Somehow my brain tells me rotaries were compacted.. but damn this engine bay is jammed packed.

Lol, my soul was crying too 🤣. Great compression though

dude your car looks so clean

What a spot 😍

Lovely FD and location 👍

It's really cool you got a space (and skills) to do all this and most importantly with your friends and hangout. I haven't hit any FD group here in the bay to do this.

Nice vids going! Super clean cars. What’s the rear diffuser you guys both have? Just the 99 spec OEM one?

I think matte dark gray wheels would fit it more, but its just my opinion bro, its good i love it ;)

Lookin sooo good ! Love the way they look on the car 🚗

They look good. It always feels like cosmetic items are secondary to mechanical when it comes to FD budgets :), but I have been toying with the TEs on my Montego as well, maybe in a bronze or charcoal color. Are you running the same size all around or are they staggered (I heard you mention the fitment on the rears)? Looked like Potenzas on there....am interested in your take on the tire over your previous configuration. Look forward to see it with the height adjustment.

You posted my red STI and me looking at your whip! Dope vid!
