RX8 turbo upgrade
 

Hello guys,

after having finished my 600 bhp Supra modifications end of april this year (PHR stage 1 turbo kit), I want to concentrate more on my RX8 which runs the following spec :

- GReddy turbo kit
- GReddy e-manage ultimate piggy back ecu
- GReddy Profec B spec II boost controller
- Custom dowpipe (fully decatted)
- HKS exhaust
- upgraded secondary injectors (680cc)

I plan to go add the following items :

- SARD fuel pump (280l/h)
- SARD fuel pressure regulator
- GReddy upgrade kit (GT3071 turbo + accessories)
- Interceptor X EMS
- Esmeril Racing Ignition Upgrade
- sr-motorsports Clutch kit
- sr-motorsports Flywheel

Any comments?

Thanks

I would change the following

- Interceptor X EMS <-- AccessPort from MM
- Esmeril Racing Ignition Upgrade <-- BHR yukon coils
- sr-motorsports Clutch kit <-- BHR Spec Stage3+ clutch
- sr-motorsports Flywheel <-- BHR 9lb flywheel

^ i agree with the above. also you may have trouble fitting the 3071R unless you get it from MazdaManiac. you can't just buy the turbo and stick it on. i thought it would be possible but it is not.

+1^^

MM (MazdaManiac) & BHR (Charles R. Hill) work together and have a very good reputation. I have meet and had a chance to talk to both of them. You won't receive better advice than this.

Thanks so far guys ... I will have a look.

Cheers

accessport is half the cost and twice as good. but there are drawbacks to every system. With that said, the accessport is as close to perfection as we can get it. The only downside that I've seen is the MAF system doesn't play well with BOV venting to atmosphere. You can get it to work, but things are popping and don't function like OEM. This is really not a fault of the accessport either. Recirculate the BOV and it's 100% like oem.

It's the GReddy upgrade kit from MM I had in mind :)

Thanks

Thanks mate.

Works on the Rex will start in march ... so I have time to get some open issues sorted out before :)

Can the Access port be setup for larger injectors (I have 680cc secondary ones) ???

pics of the supra?

yes very easily

I'm abroad with work ... will post Supra pics this week-end:)

One additionnal question I have is the following :

when I installed the GReddy turbo charger with the accessories, I also wanted to upgrade the fuel pump with a SARD unit (as 680cc secondary injectors have been installed). However, I could not access the OEM in tank pump as it seems that I need special tools to acces it.

Anyone know what is needed.

Thanks

^ you can go to your local dealer and ask them about borrowing it :P

One little more question regarding the Access Port.

I am a little bit confused as my mapper does not have to map the car on the conventional way.
As the setup will be a little bit special (fuel pump, bigger injectors, decatted downpipe and so on), how will the Access Port be set up correctly regarding the fuelling ( so far, the e-manage ultimate has been mapped on the car)??

Accessport and MM turbo upgrade!!1 you want to sell the supra???haha I know ppl don't let those things go...

But your best bet to uprage to MM turbo and Accessport...that will cost u roughly 2500 plus shipping tax etc...or wait for BHR turbo uprade.....

Ok ... but I am a little bit sceptic on the AccessPort.
On my Supe, 6 hours of mapping had been perfomed on the stand alone ecu (AEM) till it was finished (at 3 boost settings).
Having seen the installation instructions on the AccessPort, I saw that no mapping has to be perfomed. My Supe has been mapped several times (through the different upgrades) ... and I am confused that no such mapping sould be necessary on the Rex

How does the system know the setup of the car. Am I right that MM will provide the map for the setting I have (larger injectors, pump, decatted exhaust, ...)

P.S. Don't bother ... I would never sell my Supe ... not for any money ... 600 hp and 560 ftlbs are really nice :)

Another small question regarding the Fuel Pressure Regulator (FPR) :

how is the FPR to install as all the lines are hardline, not rubber?

pockets like his could hold the world. congratulations man! you live the tuner dream.

I would keep the Esmeril Racing Ignition Upgrade. They usually ship within one week.

The interceptor you may want to keep as well if you know how to tune a microtech (or want to learn) or have a local microtech tuner as you will have hassles with the MAF. If you are comfortable reprogramming the Accessport then more reason to consider but the software is cumbersome since you can't just dial on the street.

You can remove the pump without the special tool. It can be performed with a few large screw drivers (huge) and a rubber mallet. Be patient or the tabs will break (some break them and don't have a problem but I would not recommend it). It does release counter-clockwise. It is VERY difficult to remove but putting it back and removing it the second time is a piece of cake.

Traditional removal tools (the universal ones they sell through auto parts catalogues) unfortunately do not work and the Mazda tool is around $200 last time I checked.

Here some pics of the Supra.

Engine (just major parts) :

PHR stage 1 turbo (GT60 turbo with HKS manifold, PHR mid and downpipe, KN filter, GReddy 3 row FMIC)
PHR stage 1 fuel kit (720cc injectors, PHR fuel rails, FPR, twin walbro fuel pump)
AEM stand alone ecu with HKS DLI II, 3.5 bar map sensor
RPS max street clutch with RPS lightened flywheel
GReddy profec B spec II boost controller (3 settings : 1.2 ; 1.4 ; 1.6 bar)


600 hp + 560 ftlbs @ 1.6 bar

Luc

how'd you get 3 settings on the profec? It only has high/low.

As it's an electronic boost controller, I have
1.2 bar controlled by the wastegate valve when boost controller off
1.4 bar on low boost setting on the boost controller
1.6 bar on the high boost setting on the boost controller
