It isn't designed to be a recirculation valve.
The Greddy can be, though I highly recommend this valve:

I have one on my Miata and it rocks.

I live in Stockton actually. I used to live in Fremont though. Rick is the only place that I have heard of that sounded reputable and knowledgable about rotaries; the fact that he is putting the same kit on his own car only sealed the deal. I would be more than happy to have you come by.
Thanks MM for the feedback. I'm new to this performance car thing, and I'm trying to learn as much as I possibly can from these forums and trying to not sound too much like a fool. The description of that BOV sounds like it is specifically designed for certain applications; will it work in my case?

Can you do us a favour and post your dyno chart in your first post of this thread when you get it? That way people don't have to read through 42 + pages to find it ![Wink](https://www.rx8club.com/images/smilies/wink.gif)
Awesome job dude.

Can't remember if this question has been asked anywhere but after the engine is pretty well hot, and you’re going full boost did any of you take a measurement of the diameter of the plastic intake runners?
I've heard of some MP3 guys' Intake runners actually expanding and contracting as they got on and off the throttle, they're running much higher boost of course. I'm just wondering if its a issue at 5 or 6 psi?

The boost gauge is definitely a must, the first time you try to diagnose a problem with the system without one you'll regret it if you don't get one. At a minimum just buy a cheap one like an Autometer. If you don't think it matches don't install it...you can temporarily install it when you need it and then take it out. They may not be as accurate as some of the others, but for the purposes of diagnosing problems you mostly will just be looking for differences in behavior from the norm.

What about the boost gauge in the Mazda North American Operations car. I would like this gauge with the kit. Jon, do you think this would work?

Okay guys, been away from the computer for a little while, so I'm going to try to cover all the questions you want answered that I missed over the last day or so. Here we go....
Hehe.. I appreciate the thoughts guys, but I don't want to break any forum rules.. though I may take you up on this when I decide to get a Street Port on the engine in about 6 months ![Wink](https://www.rx8club.com/images/smilies/wink.gif)
![Frown](https://www.rx8club.com/images/smilies/frown.gif)
All the meandering adds character I say!
Anyway, back on topic. I've decided that I am going to purchase this kit. Although originally I had thought of waiting for a kit that produces more power, the amount the Greddy is putting down seems perfect as the 8 is my daily driver.
So, philo, just to bother you more, any tips/hints for me putting this on?
Rick's Rotary Performance in Pleasanton will be doing the install. Funny thing is, I just called them today about it and they will be installing the kit on their own car this week! He and I mentioned this same thread...what a great site this is.
I will be purchasing :
Greddy turbo kit
HKS SSQ BOV (rerouted to intake)
As for the boost gauge...excuse my ignorance, but it isn't a necessity is it? With the low boost and the fixed maps, I would imagine that monitoring the boost shouldn't be a problem.
(Oh yes...I am the person who JUST bought your CZ philo...it'll be FS now
)
Hehe.. For the little tricks, read the thread. I covered everything that had to be 'modified', such as the support braces for the intercooler. Just do a quick read through again of the actual install posts and you'll see what I am talking about.
As for the BOV, I highly suggest the GReddy Type-S. I don't have any issues with the BOV venting to atmosphere and it you do end up having MAF issues, it can be easily modified into a recirculating with an outlet adapter.
Personally, I only like the Defi gauges, in particular, the one I got. The Defi BF series gauges. You can get them in White and Amber (mine is white and is a PERFECT match for the stock gauge cluster).
That works too. But I just love the "pshhhssss" sound a VTA B.O.V gives. I recommend the Type-S, it's perfect for this application and is good for up to 18psi without destroying the diaphram inside.
Thanks. I sure will edit the first post with Dyno Results and Time Slips when I get down to the drag strip.
That's an issue that Jim (my mechanic) and I discussed. I'm running about 6.5-7.0psi, I shouldn't have a prolem with it exploding from too much pressure. However, once someone releases an aluminum one, I'm getting it. Not only is it stronger, but I can polish the hell out of it and it'll look HOT too ![Smilie](https://www.rx8club.com/images/smilies/smile.gif)
Exactly what he said. But you should get a quality gauge, can make the difference between blowing your engine, and knowing when it's about to go so you can shut down.
Also, I can't make it to the drag strip today. I've been commited to other plans by default. Those of you that are married or in a serious relationship know what that means :o

Come on people...$1 for Philodox!

However, my gauge reads between 45kPa to a peak of 52kPa or 6.5psi to a peak of 7.5psi. The average pressure I see is 48kPa or 7.0psi. I am not having any issues with detonation or the like. I believe each kit will vary a little bit from what GReddy says.
I am going to get a boost controller to stabilize the amount of boost use. I hope that answers your questions. Let me know if you need any other information.

Hey, if I’m ever in NJ I’ll personally give you my $1. Or, buy you an ice cream or something…LOL

Can’t wait for more vid’s, dyno, and time slips. You should start a new thread for these since this one is getting crazy long.

1kg/cm2=98.1kPa
1kPa = 0.145psi
However, my gauge reads between 45kPa to a peak of 52kPa or 6.5psi to a peak of 7.5psi. The average pressure I see is 48kPa or 7.0psi. I am not having any issues with detonation or the like. I believe each kit will vary a little bit from what GReddy says.

Correct, the wastegate actuator is connected by tubing to the intake manifold so it can get pressure to open the wastegate from that.

What I am worried about is the average amount of boost, which currently I am quite happy with. I hope that answers your question.
On another note,was the track closed today?? or are you going later or leaving it for another day?? I had read you might go today.......Im in Queens NY and its cloudy and they said something about snow but nothing so far..........how is it where you live?

The e-manage doesn't control boost at all, it just monitors intake vaccume/pressure so it so it can properly supply/take away fuel when needed. A boost gauge is connected directly to the intake manifold. Sometimes the air is a bit turbulant in there and can at times wreak havoc on the gauge since it measures vacuume and pressure. There really isn't any other way to measure the vacuume/boost pressure off the intake manifold that I know of other than a gauge. Does that explain it a bit better for you?

Jon be carfull with the shoe thing. I never paid attention to my ex-wife buying shoes. Then when she moved out it took two trips with a Blazer full up to get them out. When asked she ADMITED to there being $35,000 worth of them.
It's the boots that really drive it up at $300 to$700 a pair.
