The Cosmo is at the Dealer with my friend having the Defi goodies setup on the "mechanical" end...Additional adapters and parts are needed to install the boost, oil and water sensors.
Unfortunately, The Mazda Dealer has to close at around 6 now which means it's almost impossible for me to meet my friend after work for any extended period of time like before...Luckily...My friend is going to continue to help me with the project and hook me up with a well known shop in the nearby city of Amagasaki for all my hardcore tuning needs!
I believe I'm going to checkout the shop with him during our next meeting this Friday!
Last Meeting: May 20th
Next Meeting: June 6th
Mod Status:
* Checkout the shop (together) in Amagasaki that my friend recommends for my hardcore performance and tuning needs!
* Check progress on Defi sensor setup
* Discuss the final approach for the custom Defi glovebox & RE Amemiya steering column pod setup
* Order OKUYAMA cooling plate & front strut bar from the shop in Amagasaki
* Defi goodies have arrived and are waiting to be installed!
-- Defi's new "Racer Gauge" for Boost (not the best name imo but it comes in size 52 which I need for the pod as 60 may be too large)
-- Defi-Link Display
-- Defi-Link Control Unit II
* New idea...Would the Defi Link Display look good and be functional as a custom display in the place of the ashtray?
* New hood insulation kit...Go custom???
* Price range check on re-painting the side view mirrors...Don't forget to ask for an update this time!
* Check the condition of the factory body/aero kit and make sure it's securely fastened to the body in all areas!
* New Cosmo sign and Eunos logos so that I have new ones in case I need to replace or refresh the current ones...Don't forget to ask for an update this time!
* Autoexe grounding/earthing kit arrived...installed yet???
* Once StageII is complete...Detail interior and condition leather!!!
* Possible custom name plate mod in the works (Stage III?)...More on this later...
I miss my ride...I'll be looking forward to seeing Pay2Play on Friday!

Yeah...I've been lucky...Big Thanks to my friend at the local Mazda Dealer for being so helpful!
Doesn't hurt that he is a major Cosmo fan as well!
Good to hear that the Cosmo is going strong 
Mine was off the road for a couple of days. I thought a fuse had gone, but it turns out the head light bulb holders had melted. Easily replaced and fixed by my mechanic. Might be worth checking out on yours.
No idea yet why it was like that. Seemed to happen over a long period of time.
Last weekend I also went to a Rotary dyno day (hosted by the local Rotary guys). The Cosmo pulled 190kw and was 3rd least powefull on the day with an RX2 13Bt pulling 395kw being 1st.
Have you taken it on any long cruises yet?
Anyway keep up the good work

Hmm...I've never heard about the head light bulb holders being a problem but I'll mention it to my friend and we'll see if I'm going to face the same problem...
I'm glad to know you've hit the dyno...I'd like to do the same someday...Seems 190kw would be about what a healthy stock setup would make at the wheels (especially being a early-mid 90's car)...What boost levels are you running?
As for long cruises...I did drive it to the 7's/8's meeting at Central Circuit which is deep in the Hyogo countryside and despite the rain...It was a blast in the Cosmo!
My Alpine navi unit got me there without any problems and the rain seemed to keep the 20B cooler than normal...I was cruising effortlessly at about 2800-2900 rpm in the fast lane.
Even on country roads...The Cosmo was a smooth and controlled ride...I had a good time through the twisties...Even in the rain.
I can't wait to get the Cosmo back from the latest round of upgrades and head out on a trip...Just me, the Cos and the 20B.
Keep in touch!

Rain or Shine...Another UPDATE!
Current
Pay2Play has had all the Defi goodies setup including all the sensors at the Mazda Dealer...For that past 2 weeks...It has been at the Pro Audio guy's shop having the custom glovebox setup including a new plan to incorporate the Defi "Defi-Link Display" where the ashtray resides...which should complement the custom Navi/Air Con Center Consul setup nicely (thumb).
Last Meeting: June 6th
Next Meeting: June 13th
Mod Status:
* Check progress on custom Defi/Glovebox setup
* Check progress on custom Ashtray/Center Consul/Defi setup
* Checkout the shop (together) in Amagasaki that my friend recommends for my hardcore performance and tuning needs!...No time last time...Maybe this time?
* Color match RE Amemiya steering column pod with the custom Ashtray/Center Consul/Defi setup
* Order OKUYAMA cooling plate & front strut bar from the shop in Amagasaki
* New hood insulation kit...Go custom???
* Re-paint side view mirrors...The question is when is the best time?
* Factory body/aero kit condition checked...It's in good condition but it's also difficult to figure out how to adjust or tighten it..?
* New Cosmo sign and Eunos logos so that I have new ones in case I need to replace or refresh the current ones...Don't forget to ask for an update this time!
* Autoexe grounding/earthing kit arrived...Installed with the "Factory" look in mind...In others words...CLEAN
* Once StageII is complete...Detail interior and condition leather!!!
* Possible custom name plate mod in the works (Stage III?)...More on this later...
* Once the RE Amemiya steering column pod w/ Defi Boost gauge is installed...Check boost levels and consider ordering a Joe P. Pro-Z TT MBC for a tried & true solution to maintaining proper boost levels
The Pro-Z TT MBC features a second outlet port specifically for Twin Turbo applications.
* Check condition of Turbo hose lines...If they need replacing...Decide to go with stock rubber, silicon or 100% Viton!
I really miss my ride...Luckily, I'm going to check on the latest progress after work tomorrow..Stay Tuned!!!

mechanical boost controller? surely with all the money you're spending on the ride, you could shell out for a nice ebc with the ability to switch maps. That way you could have a low boost for economy, high boost for thrashing the pants off anyone silly enough to line you up in a red light GB - all at the touch of a button.
Check out the Turbosmart e-boost 2 boost controller. 4 "boost groups" (boost maps more or less...why they call them "groups" i don't know...), control over sensitivity, solenoid opening rate, digital display and a plethora of other features all for a fairly reasonable price

Haha...It didn't take you long to notice I updated ye 'ol thread...Actually, I was originally thinking about running an EBC...but I've come across some hardcore rotary guys who favor the simplicity and straight-forward nature of the MBC.
I stated I was considering an MBC...not decided yet...but you do make some solid points about the range of options that an EBC offers.
Price is not the main factor...Performance, quality and the right match are the factors that will decide my purchase.
I'll have a look-see at this Turbosmart e-boost unit...How does it compare to the crazy setups from Blitz, Greddy and HKS?

Turbosmart products are favoured by all the hardcore guys down here..doesn't hurt that they are local products for us, made to exceptionally high quality. I've ONLY ever heard good things about the eboost2 unit. My only gripe is that it seems a bit "involved" to set up (lots of settings...pertaining to things such as sensitivity, or how quickly it alters the solenoid position - which directly relates to the smoothness of the boost curve, gate settings which control how rapidly the boost controller allows the waste gate to open and so forth). But yeah...top piece of kit - and its a digitial boost gauge to boot.
I guess most of the "hardcore" rotary and turbo guys I know are into drag racing - simplicity doesn't even enter into the equation when you are vying for that last one hundredth of a second - but i'm just wary that your car is already a gas guzzler - feeding it more boost with no easy/quick way to moderate the boost when you don't need it is just going to add additional pain to the hip pocket.
High end electronic controllers also give you the ability to control HOW the boost comes on, whereas MBC's will just bleed a constant amount of pressure off, essentially meaning the turbo will spool as fast as it can build boost. Whilst this all might sound great on paper, in practice a more moderated approach to how the turbo comes on may be easier to live with on a day to day basis.
You may also consider sometime in the future whether the stock cosmo EMS can keep up with your high performance demands. I imagine the computer is fairly limited with regards to how far it will let you push the power and boost up.

Antoine asked how much boost I am running. Stock pressure, peak is 9psi I think, but it is normally around 8.
LordWorm said the Cosmo is a gas guzzler! Fair call I guess. Although the latest official figures from ford for their new Falcons is worse. I get 12ish litres per 100km on the highway with aircon running. Now that it is winter I will have to see what it does with aircon off.
The stock EMS is of course limited as you would expect, but from talking to a few mechanics and other rotary guys it would not be too hard to fit a piggy back system. That is something I am looking into as it is running a bit rich. A piggy back system will give me the ability to lean out the ratio to remove the flat spots in power. Running on the Dyno was useful, the 20B is healthy but the EMS is running it a little rich. Resulting in a not perfect power curve.
The stock turbos are also only good for a bit more than stock pressure. If I recall correctly they are good for 1BAR and then they start to break, that gives us a little room to play with but not heaps. Although one of the guys in Australia got his stock turbos replaced with new ones from Mazda, so they can't be that hard to find.
Does anyone know if they are the same as the RX7 twin turbos?
More photos of the Cosmo please

Proven time & again, the MBC allows boost spikes that will kill the turbo's. Just troll the FD RX-7 forums to read all about it.
The trusted weapon of choice is the Blitz SBC or similar. However, the recent HKS EBC is proving better again.
Note the boost levels dropping on my 20B as the revs rise. The dropping boost is not due to the EBC but despite the EBC's best efforts, the turbo's are simply running out of flow & pressure levels suffer as a result. 227KW @ rear wheels means the standard turbos are struggling to flow more than 300KW through them & if you have ever seen just how small the rear turbo actually is, you will scratch your head wondering how they flow even that much.
My recommendations........ Go with the HKS EBC
Note: the lower KW dyno run (upper pic) was when I had "boost issues". The high KW run (lower pic) was after the Blitz EBC was installed & boost was restored.

pics of defi setup?
Once "Stage II" is complete...I'll have those pics
Mucho Gracias for all that info...I checked out the eboost2 controller and it's definitely a nice unit...After checking out all the options once again...I agree that going the EBC route would best suite my needs now and in the future.
I've decided to go with the Blitz SBC i-D Spec R (dual solenoid) after researching on the net and hitting up the local Super Autobacs to see the controllers in person.
As for an aftermarket EMS...I realized early on that at the end of the day...The only way to make the most of engine mods with the 20B TT is to go with an all-out EMS/piggy-back system...The stock ECU can handle minor mods but if I wish to do serious engine mods in the future...I WILL need to factor in an aftermarket EMS or piggy-back type system.
Even if I want defeat the stock fuel and speed limiters...safely...I would need to go EMS/piggy-back. Although HKS does sell this unit...SLD (Speed Limit Defencer)
I spoke with the guys at FEED a couple times and they recommended going with the HKS F-CONV Pro (you need an authorized HKS Pro shop to install this unit in Japan). It's quite involved and would require some pricey accessories and tons of tuning time...but as I like to say...You've got to "Pay2Play".
In anycase...The Cosmo in its current state is no slouch and already a monster but I'm sure once I get the new Blitz unit dialed in...It will enhance the Cosmo's current power levels and delivery even at stock boost.
I believe the stock boost is around 7 psi...and going beyond 10 psi is asking for trouble with the stock ECU and Turbos...I plan on setting the max at 8 psi for now and see how that feels for a while...
Antoine asked how much boost I am running. Stock pressure, peak is 9psi I think, but it is normally around 8.

Thanks for chiming in...The more Cosmo fans we can get posting in this thread the better! (2thumbs)
I'm glad to know we've got the same information about the Cosmo/20B's performance potential...If you decide to go with an aftermarket EMS/piggy-back system...Let me know! I would be very interested to know about your experience setting it up and the results/advantages/disadvantages/issues etc.
As for the Turbos...I'm entertaining the thought of keeping the same turbos but at some point (maybe when/if they go bad) upgrading the internals for more flow and quicker spool time (ball-bearing units would be sweet).
I believe the RX-7's TT setup is not the same...including slightly different turbos.
Keep us updated and I'll have more pics coming soon!

Thanks for the additional input...As mentioned above, I've decided to go with the Blitz SBC i-D III Spec R (dual solenoid).
The latest HKS unit looks really cool but I like the overal look and setup of the Blitz unit.
I recall your dyno pics from your site...It's interesting to note the flow limitations of the stock turbos...but I like a challenge...I wonder how much performance I can safely get with minor mods and a boost controller...
Speaking of boost...What boost were you running to achieve 227kw @ the wheels? How has the re-amemiya ECU been working out...Any issues since you've been running it?
Now for another update!
Current
The custom Defi glovebox setup is currently being fabricated and will include a Blitz boost controller. The Defi-Link Display will no longer reside in the glovebox as previously planned...After hearing my idea to locate the Defi-Link Display in place of the ash-tray...The Pro Audio guy has come up with a really cool way to mount it IN the ash tray allowing for the stock flip-open cover to remain...I can't wait to see how it came out! (2thumbs)
Last Meeting: June 13th
Next Meeting: June 23rd
Mod Status:
* Check the final stages of fabrication on the custom Defi/Glovebox setup
* Check the final stages of fabrication on the custom Ashtray/Center Console/Defi setup
* Blitz SBC i-D III Spec R on order!
* Confirm location and install details for the Blitz boost controller to be custom mounted in the glovebox along with the Defi and ETC unit
* RE Amemiya steering column pod, custom center console face plate and ashtray should all be repainted and color matched
* Order OKUYAMA cooling plate & front strut bar from the shop in Amagasaki
* Re-paint side view mirrors...Reserved for Stage III
* Factory body/aero kit condition checked...It's in good condition but it's also difficult to figure out how to adjust or tighten it..? UPDATE: Turns out the Pro Audio guy is quite knowledgeable about body work and has some ideas on how to ensure the factory body-kit has the best fit possilbe...More on this with Stage III
* Check condition of Turbo hose lines...If they need replacing...Decide to go with stock rubber, silicon or 100% Viton!
* Once StageII is complete...Detail interior and condition leather!!!
* Possible custom name plate mod in the works (Stage III?)...UPDATE: Stage III is already taking shape and will encompass mainly exterior/aesthetic mods
Stage III Preview!
- Custom body-kit name plate...Here is a pic of the current factory setup...
- Repaint side-view mirrors
- Make sure factory body-kit has the tightest & cleanest possible fit
- Remove all scratches and scrape marks
- Checkout the possibility of having the current rims cleaned, polished and coated...Price?
- New Cosmo sign and Eunos logos...Available still?
- Clean tail pipes!
Project Pay2Play is really picking up steam now...I can't wait to take it out for some much needed exercise once Stage II is complete! (rockon)
