The only check valve is on the vacuum line to the VFAD, which you remove to plumb the BOV.

Here's what I did , 1st I heard that if I put a Check valve between the jet fuel mettering hose and the air filter , that it will smooth out hesitation between shifts and just in general.
And 2. I was told to soften my BOV- RS because I was still hearing the whoosh and like a flutter ( from still too much air not being released) So I soften the bov just enough until I could not hear the flutter..
Well, I don't really know which one did but it sure as hell help alot.. Thanks, Hey Jeff put your 2-cents in.. And I have a complex question for you when I get A chance to really sit down and write that out.. Right now I'am going to have alittle fun with my car.. good nite...

Sorry must have explained wrong. What I meant to say was (as per above statement) That after I was told to install one, because it would help smooth out shifts, and you said it was probably just the BOV I adjusted.
I wanted to see if that was true in my case, so I removed it and then reinstalled to see the results on my car and it does make a difference..
So I was looking for some reason for the change and asked you if you thought that when the car was under boost if the check valve was preventing any leakage and maybe that was the reason it was helping...

Jeff, the Greddy install manual 3.5 Airinnx installation, (7) says to connect the jet air fuel mixing sir hose to the fitting on the airinx. I installed the check valve between the two...
and it does make a difference on my car..
So as I said previously, do you think by doing this will prevent any leakage under boost to escape through the airinx(greddy air filter) and that's why it seems to help my car...

Well my question to you turbo fellas is, What are you going to do when your rotory(known in the past to not mix well with turbos) goes out on you? And we all know slapping that greddy on there instantly voided your warranty. You gonna haul it back to your house, pull off the turbo, then call the dealer and be like: "I don't know what happened mang..." lol For real man i want to do this upgrade because its cheeeap, but damn im scared for my rotory, given its history with turbos. Im guessing that you guys havent hit 50k Miles(turbo attached) on the car. Which was the point in which the RX-7 became a grenade with no pin. If i see you guys make it past 50-60k with the turbo installed, i might think about it. Until then im going to sit back and wait for yours to detonate. All pessimism aside, because i really like you guys installs.

The issue isn't the combination of rotary motors and turbos. It was engine management.
Many owners increased the boost on the FDs without addressing the speed density EFI system.
Add to that the peripheral port exhaust (and the resultant apex seal issues when dealing with detonation) and you have a recipe for trouble.
There are quite a few Turbo II FCs out there that are approaching 200k miles on the original engine.
I'm getting close to 30k miles now, over 10k of those with the turbo. I'll hit 50k about this time next year or sooner - if I do the cross-country trips I have planned in the RX-8 instead of the Miata.
I guess we'll see.
Until then, enjoy being slow!

Would it be possible for someone who did install to draw out simple schematics of all hoses pipes used by this kit ? I am going to be installing it next week, but i never really had chance to work on RX-8 yet, only on RX-7's. I had all bits of kit in hand today, read manual but its missing simple outline of all pipes/hoses and directions of air/fluids as i am used from RX-7 factory shop manuals.
Its just few hoses, should not take too long to draw out for someone who understands how it works.
thanks

So you are saying that every FD owner who blew an engine didnt take care of it? hmmm. Also, you didnt address what i said about the warranty...oh yea what warranty. :D I suppose its a price you pay, but figuring in that the overall cost of the car's sticker price does include even the basic warranty(i believe), then that means your turbo install probably just doubled or tripled being that you had 20k more miles left on it. That is just one perspective on it. Did anyone purchase the extended warranty and then put a turbo on? Now that would be hilarious...
P.S. mommy, the turbo guy called my 8 slow wahhhhh!
hehe

I dont know much about the FD but my friend owns a 93 with many mods. He takes damn good care of it, taking it to only the best rotary experts in his region, and he still agrees that getting rid of it is a wise idea.

Putting a check valve on the air bleed hose will do nothing as far as I know.
You and several others who have installed your Greddy kits have done small modifications here and there and are having issues or are solving issues that I can't comment on because I cannot see what you have done.

Swapping out Airnx filter
I don't want to use the Airnx air filter from the kit. However, the kit requires that you connect "the Jet Fuel Mizing sir hose to the fitting on the Airnx using provided hose fitting and -9 hose." How can you bypass this? Will this affect the perfermance or throw off a check engine light? Shesh...

Greddy hoses
First pic shows the 3 hoses on the stock intake tube and the vfad hose that connects behind the throttle body.
The 3 hoses (oil filler pipe hose, jet air fuel mixing hose, oil metering hose) will be reconnected. The vfad hose needs to be removed and replaced by the greddy pressure sensor hose.
The 2nd picture shows where to connect them.
(Note.. You will have to add an attachment and extra hose for the jet air fuel mixing hose to reach the intake. It's all included with the kit.)
EDIT: I BELIEVE THE YELLOW LINE HOSE IS THE JET AIR FUEL MIXING AND THE WHITE IS THE METERING OIL HOSE. THE PICTURE ABOVE HAS BEEN UPDATED TO REFLECT THIS.
I'm not certain, but it shouldn't matter, both are getting air from the airnix intake.

Turbo actuator hose
Connect a hose from the nipple on the gold turbo actuator to one of the two nipples on the lower left intake manifold. I connected my boost gauge to the other nipple.

Oil line
Connect the oil supply line to the T-fitting and the other end to the turbo.
Then connect the oil return line from the turbo to the oil pan drain. (Pic shows my greddy oil pan which has extra hole and is not included in the kit.)
