Ah yes.. mind is working again. Comments on cooling system flushing procedure and what to recharge with? Prestone 50/50? Water wetter? And I have a 160 degree tstat new. I think the one in there is a 195 summer. Now that I'm in the south do I want to do the 160?? It seems to make sense.
im going to take out the radiator and try to have dipped stripped whatever they do and hope they can save the top externals. I've seen them come back and they strip the numbers off. I'd like to keep them but maybe not possible. At this point is it advisable to replace any sensors?
carlos advised a 5 degree timing advance because of my headers and free flow exhaust. Comments?
This diagram seems to spell it all out for access easily to the fuel rail, injectors etc. I don't have to unbolt anything up top(?) Just unbolt down below where it ties into the intake manifold. Nothing above is affected. (?)
First off, I'm not a shill for mazdatrix, they just have a website that I think is clear. Feel free to buy from whomever you prefer to support with your rotary monies.
For SE injectors, I've never had a problem with the stockers, so long as they're flowed. If you send to WitchHunter Performance - Injector Cleaning & Flow Testing Services, they'll sort them out on the cheap. If you don't end up with a pair that flows similarly (which is a HUGE deal on the SE with just two injectors) he'll match them with others and deliver a nice pair. Add fuel rail o-rings and engine block grommets, and you're good to go there. Consider pulling the air bleeds out of your intake runners too - they sit under your injector pintle and are a little diffuser basket, the size of a thimble. If they're broken, they're $50 to replace. Hopefully yours are fine, but you'd hate to go to reassemble and fine one broken with a week to ship....
Injector o-rings and grommets - mandatory. Air bleeds optional, depending on what you find. Fuel Injection Parts
Whether you service your pulsation damper, defeat the one on the rail and service only the fuel pump - that's really up to you. Personally I have no problem with either approach. A replaced damper will outlive Robert and Ray. Pulsation Dampers
Fuel lines are the ones you want to get un-lined - just pressure-rated rubber is fine. Fuel line with a blue plastic liner will absolutely not work on the flared steel lines we have. 3/8 supply, 5/16 return. And the silicone vacuum lines are super cheap - you can buy a fistful and replace the rats' nest 2" at a time. Super easy. Silicone Vacuum Hose
You shouldn't need any intake gaskets if you're careful to tap the manifolds as they come off. Remember to try to slide them to the side and tap them with a rubber mallet. If you lift straight up, they might stick to both mating parts and tear. Slide them across the face of the gasket, and it'll stick to one manifold or another. It's not my clearest advice ever, but I hope you get the picture. They should be easy to reuse. The intake manifolds and plenum really are super easy.
The final part we didn't talk about is the fuel pump under the car. It has a pulsation damper back there, as well as a fuel filter AND an inlet screen that's a little cone, like if you cut the tip off an icee cone thing to let the juice drip out. It's worth a look and to replace the fuel hose, but if you want to limit your scope and just focus on the technical stuff under the hood, then come back to the fuel pump some other weekend, I could see that.
I've never had OMP lines break. They seem to fail when you monkey with them. If you leave the lower manifold on the block and don't mess with them, they'll be fine. Besides, they get expensive.
Just like that!! Outstanding. For the most part answered all the "Crit"ical questions. I'm on it! I don't like my car sitting so I'm on to the next step which is ordering parts. Thank you.
Cindy has Crit and Tommy on her FB. Crit I didn't know you are a ME. Now it makes sense. Tommy? That is one bitchin model A you have on your FB. When everyone talked about it at the cabin I figured it was a project.. I hope to see it in person someday. I've never had a ride in one.
Paul, if you get the part numbers for the hoses, injector seals, gaskets, etc, you can likely order them through your local dealer and save a few bucks. I did the entire fuel system on my car about a year ago and got almost everything through the dealer, their prices were competitive and I didn't have to worry about cheap Chinese or non-OEM stuff going on my car.
On the fuel hose, if you get it from the parts sure, make sure you get the hose rated for fuel injected cars. There are different types and some do not have the high pressure rating for FI systems. Back when I did it, it was cheaper to get it online: 247 NEW BARRICADE FUEL INJECTION HOSE 3/8'' 15FT ROLLS MADE USA | eBay
You can use the parts store vacuum line, no need to get that stuff from the dealer. If you want to get fancy, you could get silicone line. Most hoses are 4mm I believe. I get mine from here: Silicone Boost/Vacuum Hose
I think the 50-50 coolant mix would be just fine. I use the cheap Walmart branded coolant personally.
For your 5th/6th ports, you're probably better off leaving them alone if they are working properly. You can put a zip tie on the base of the actuator rods, then take the car for a spin. If the zip ties have moved after your drive, you have verified that the ports are opening. You have to take off the lower intake manifold to remove the sleeves. I don't think you'd have to remove the lower manifold for anything else though.

I'll disagree with you there, Brett. For any other car, coolant doesn't matter to me. After years of blowing coolant seals, Mazda finally figured out a coolant that doesn't decompose silicone seals and specified it on the later RX-8s. I imagine (more research needed here) that it would be a good idea to the earlier cars as well. Mazda FL-22 is magic. As long as you can keep some in the car (looking at you, FB storage bins) you should have enough to top off with a leak and never have to get the old crud back in your cooling system again.
I'm not convinced it's required, but a few gallons of coolant is a small price to pay vs a forced, unplanned rebuild.
All of this info is important for me to make the right choices. I studied the manual late last night and came to the conclusion that I need to prioritize my moves. I can't afford to do all this at once. But, all of it has to be done. Im going to concentrate on the cooling system first. Besides, I know I can handle that much myself. As for fuel and vac hoses I'm not so sure I want to tackle that without a veteran in the room. But, I will be purchasing what I need shortly as I go along. I'm hoping to get my bud from Ohio here soon. He did, with a little help from me, all the minor restoration on it winter 14-15, now 9000 miles ago.
Looking for for a definitive answer though Crit alluded to one. Is it not a good idea to purchase New injectors? Better to remove send out for rebuild/flow?
On the coolant I think the Best is worth it. What's the proper way to flush this system?
I agree with Crit there. Fl-22 isn't *THAT* expensive and it's peace of mind. I've actually been using zerex Asian for a year now, but I don't feel good about it. My next flush before I move will be the Mazda stuff. I used to use plain Jane green, but then switched to FL-22 for a few years.. Then turbo swap happened and I cheaped out and used zerex Asian. Shame on me.
In more exciting news.. Once I get my 720's serviced and obtain a racing beat downpipe, my hybrid turbo can finally go in.

well I tend to agree with you. As frank Zappa once said" nothing but the best for my dog.. not speck of cereal". Coolant is the lifeblood next to oil.
Acesenugal !! I've seen your posts before but I don't know who you are yet. I'm Paul!! Owner of the "award winning" black 85 five letter!! (That's a rib shot to Robert and Ray). I simply have to run this into the ground. lol. Were you at DGRR this year?
I was not, I've been in Vermont for many years now. I wormed my way into the OGTA around late 07, early 08. My name is Collin :-)
Never been to deals gap, weirdly.
Edit: To elaborate a bit, I used to live in Georgia with the rest of these rotards, but moved to Vermont with my family. I haven't exactly been active in this thread since I left, but I pop in once in a while.
I've never owned a first gen, but respect them for what they are - the original RX-7. I've always been an FC man, the draw to them being a larger and more comfortable interior, more refined road manners and the extra horsepower out of the box. I'm sure I'll own a five letter some day, though!
Second edit: As I'm sure you've already found out, this gang is very easily the best the rotary community has to offer; it's members are some of the most knowledgeable and accepting while almost always willing to help a fellow rotary enthusiast in any way that they can.
Now that I've buttered everyone up like a piece of toast, I'll just go quietly be in the corner... Hehe

I've really wanted to add a beautiful stock black TII to my "collection " of one. There's one in Minneapolis CL right now that id love to look closer at but it's not in the economic cards. I drove a couple FC in the late 80's. I liked em!! Very different than my SE. Maybe someday.
Damn, you guys are sounding like a bunch of liberals.
Half way intelligent.
Except for that FC stuff. 2nd gen, really?

FRANK ZAPPA LYRICS
"Dirty Love"
[backing vocals Tina Turner & The Ikettes]
Give me
Your dirty love
Like you might surrender
To some dragon in your dreams
Give me
Your dirty love
Like a pink donation
To the dragon in your dreams
I don't need your sweet devotion
An' I don't want your cheap emotion
Whip me up some dragon lotion
For your dirty love
Your dirty love
Give me
Your dirty love
Like some tacky little pamphlet
In your daddy's bottom drawer
Give me
Your dirty love
I don't believe you never seen
His book before
I don't need no consolation
I don't want your reservation
I only got one destination
An' that's your dirty love
Your dirty love
Give me
Your dirty love
Just like your mama
Make her fuzzy poodle do
(Oh, Frenchie . . . )
Give me
Your dirty love
The way your mama
Make that nasty poodle chew
I'll ignore your cheap aroma
And your little-bo-peep diploma
I'll just put you in a coma
With some dirty love
Some dirty love
That dirty love
That dirty love
THE POODLE BITES!
(Come on, Frenchie)
THE POODLE CHEWS IT!
(Snap it!)
THE POODLE BITES!
(Come on, Frenchie)

Now your talking ray!! Mothers of invention!! Frank was THE man. Hard to believe that he never drank, smoked anything, took any drugs.. a true trail blazer in Rock and Roll
You know at the show.. it was my birthday Saturday. Cindy, my fiancé, wanted to surprise me with a "free compression " check. That's how the whole fooking thing got rolling.!! It seemed like a great idea. I saw the dude do two others around me. And YES I wanted to know if all the pampering at 119k paid off!! Robert I think asked me UP at the cabin.." why in the hell would you let anyone touch your rx7??!!" What he said!!!!!!...hell I don't know.. a moment of total liberalism I guess... it came with words FREE!! Just goes to show you.. you gotta earn it. The freebies will get ya every time. More on this glorious rollercoaster weekend later. Gotta get my banjo and jam a few...heh heh
