So Manuel, based on everything you've done to the Greddy kit it would be great if you could provide some insight as to the best upgrade path to follow. Once the Greddy kit is up and running, what modification gave the best bang for the buck? Maybe write up an upgrade plan detailing the order of modifications to make.

Hey Manuel,here in Greece we hit very high temps now in summer...Today i ve got 41celcious....And the car was very very slower than before....

So tomorrow i am installing the greddy turbo adn all the addons and i really considerfing of buying an aftermarket bigger radiator to run the engine in lower temps...

I was thinking of mazdaspeed radiator but someone told me that pwr makes the ms radiator too and its the same unit...The price difference is pwr 1/3 of the ms price so its big...

I really think that pwr is a good choice and it will sure help me out...

What do you think with all my thinking..??Is it a good way to go?I want my car to run very very safe....

Also are there any gains from a bigger radiator??
I can post some links if you want to see the radiators...
You run the stock one still??Considering to change??

GrRx8MaZdA

Welli started the installation today and i ll finish it tomorrow maybe...But here is what spinning in my mind and i can't sleep...I have canzoomer midp-4 which use a 5" size catalytic system when the stock stystem use a 2" size catalytic...
Well is there any chance to accidentaly increase boost with the highter air flow and have a problem with the turbo running in highter boost??

I also have greddy sp2 and by the time we speak we are connecting the revi with the turbo...

Please help me!!!!

p.s. I ordered today pwr radiator

Sorry guys I was on Aruba with my wife for the weekend,

Rkoslolni,

I really can't tell you what to do first or next.................

because for me everything depends on which is your goal, 250HP?275 HP?300HP?350HP?

Of course that more HP = more $$$

This greddy kit works great on the RX8 and with this kit the car is a different car but
this greddy turbo is good for anyone that is looking to have his car on the 250-275 HP range. I don't whant that anyone feels bad......................

I'm really looking to put my car between 325 to 350 HP, but now the big problem is our small turbo. To get our goal I already spend more $$$ on injectors, ECU, coils, etc, so,
we're thinking on different options....................

The first one is replace the greddy turbo.
Second one is to replace/change the propeller on the greddy turbo.

For the first option our problem is space, we're thinking on different ideas like put the
battery on the back of the car and use that space to install a bigger turbo like a GT35.

Another option is cut the compact of the car and install the bigger turbo.

for any of this ideas we would need a custom manifold and is not cheap......

By the other hand change the propeller is not expensive but I really don't know how much more power we can get. The problem is that if I do that I don't know if anyone whants to buy my greddy kit with that modification.

My mechanic already have a person interested on buy the kit,
If anyone is interested just let me know........................

Right now I don't decided what to do,
but if I sale the greddy kit I would need to make something...............
let see what happens.

GrRx8mazda,

Puerto Rico is also hot all year around and our humidy is near 90% and more.......
I'm using the stock radiator without problems.........

I really recommend you that install the greddy kit and use the car for some weeks
and see how it works before try to make other changes.

When you installed the kit please check you're temperature at crossing for the first days .......

Go to a dyno and make some runs on third gear and check you're HP then
make a run on 4 gear and be carefull that you're car is not making detonations.

I don't know how good are the Greece mechanics with rotaries but find the best one!

Hey Manuel,have you installed a battery relocation kit yet??
I don't have space with the revi box under the hood and i am trying to find a good trunk maybe relocation kit..

I send an email to petit racing to found out more about their relocation kit and where they relocate the battery...I t will be very usefull cause we have a lot of job to do and we need more space...

Does anyone know anything about the petit racing relocation kit for the battery,except the price???
Also if it will come with a new battery will i have any problem with the wires or with the car itself???

Now waiting for a portable pc notebook to install in the dash to use with the scanalyzer with 10" most screen size(i m trying to find one with 7" or 8" screen buy nothing yet),pwr radiator and waiting 4 a reply from pettit racing for their battery kit...

We ll see..
Manuel i really really apreciate your help!!

Also is it a good option to change spark plugs ??hks or greddy??but all the spark plugs from both comps(all the 4)are 10 size....no 2 9s and 2 10s??Will i have a prob with colder spark plugs??


Also btw
1.Has Anyone used canzoomer canscan to take numbers from the car??In what numbers(stoichiometry) are you running??11?12??

2.If anyone has the profec e0-1,where do you connect the pressure sensor?In the emanage or in the e0-1???

3.And how many modules has the emanage??2 or 3??

RX8PR

My friend relocate his battery on the trunk but it was a custom kit.

I would need to make it on the future..................................

On the spark plugs I recommend you to use colder sparks

I use NGK 10.5,

you can change them every 6 months or every 12 months,

depend on the use.


Manuel

GrRx8MaZdA

can you please manuel answer the other questions too???

i know have a probl with the air pump...it continues working for more than 3-4minutes....without moving the car..just start it,let it cool and then turn it off..emanage problem...

RX8PR

I'm not using the profec E0-1 I'm using the profec type-s and is really easy to install it........

But all the greddy boost controllers came with instructions and diagrams that expalin how

to connect it, depends on different configurations, for example if you're using internal or

external waste gate you need to conect it different.............


The emanage has different modules but some one can't work with the RX8 confguration like

the timing control for example................

Don't do it by yourself..............Find a tuner that know how to work with emanage.

The air pump is ok now..No problem the car runs very smooth...The only problem has to do with the cat and the high flow system now cause i am running lean..Not too lean but lean..We have to install
the bov now
the revi with custom tube
pwr radiator
relocation of battery
rmagic ground system
Oil catch tank in the stock battery box

All next week...

The question is will i have a problem-any problem-by isntalling the bov rs????I mean in the circulation of the air...????

Also the boost was steady in 0.4bar which is the greddy turbo number but the temps were high so in the night with smaller temps it might get bigger so i might get my f@#@# stock cat back

The conclusion is that i am very glad with all the installation so far..I ll have the car in my hands in more than a week cause i ll install the lambo doors kit also so i ll be a happy owner when i get it back again..!!!!I appreciate all your help guys....

Thanks Manuel for the great feedback so far-pleas answer my last questions(for today though :D )

RX8PR

Make a search on this site and find one of the Jeff's map and install
it on your emanage, then make a few dyno runs to see your FAR,
make corrections to run more rich, save it and you will have your own map...........

How lean you are right now?

Install your cool spark plugs...................is for safe.

Manuel

GrRx8MaZdA

the hks spark plugs are all 10"s the greddy too...what should i do??is it safe to buy the 4 spark plugs all the same size??10s??

RX8PR

I only used NGK................

use all the same one.

GrRx8MaZdA

all 4 same size??sure i won't have a problem??

the greddy and hks are not specific for rx8..They just say rotaries...
Yours are 10.5 all 4???

RX8PR

Yep............................

Manuel

RX8PR

Sorry guys but,

Today I meet a guy that is really interested on buy my greddy kit............

When he pay me I would get the kit out of my car.

I'm waiting and working on the selection of the new turbine that I'm goin to install........
Making the new custom manifold would be interesting.

let's see what happens!

Manuel

GrRx8MaZdA

I am with you bro...Keep it up...The greddy was not for your goals!!

Hi Manuel,
Could you tell me the exact model of the NGK spark plugs? I tried to look for 10,5 but they ask me a number like Re7 or something like that. Are u using 2 leading and 2 trailing?
Thanks

Lschiavo

Hi guys, If i am planning to go around 280 Hp or 10 psi, which injectors should I buy and how many?? I just want to make sure I have extra room to get more fuel in the engine and not be on the limit of the stock injectors. 500? 800?
Thanks

neit_jnf

Quoting MazdaManiac:

"I can go as high as 10 PSI without detonation on the stock injectors and I still have a little bit of duty cycle left on the primary 2 injectors"

You should be ok

RX8PR

Ls chiavo:

the sparks are,

NGK part no R6725-105

Just for your information,

If you are thinking on bigger injectors you would need to make a custom fuel rail
and new coils..........I recommend that upgrade the fuel pump, to upgrade the fuel pump you need to make a return line.

Manuel

Luis,

The 1 heat range colder NGK plug is : RE8A-L (Leading only)

I have the Denso Iridiums. 1 heat range colder on both leading & trailing. But the factory plugs are NGK's. Not sure if there is any big difference between the 2.

Jeff (MM) stated that the stock fuel pump is 255 lph. That is pretty big. Many times when people with other cars upgrade their fuel pump they go to the Walbro 255 lph (liter per hour) pumps.

Lschiavo

I apologize in advance for this post, but i dont know how to explain this in english. I am to Manuel explaining a weird thing my car is doing.


Hola Manuel, me llamo Luis y soy de Venezuela.
Hace poco instale un turbo Greddy con un HKS SSQV BOV. Tengo un sonido muy extrano cuando suelto el gas y he llamado a todo el mundo, todos los amigos que saben de turbos y cada mecanico en la ciudad y no saben decirme que es lo que pasa. Cada quien me sale con una historia diferente. Unos me dicen que el sonido es normal del BOV, otros me dicen que esta regresandose el aire al turbo, otros me dicen que mi pipe no es lo suficientemente ancha, otros me dicen que el sonido es normal de los turbos. Es muy raro, cuando suelto el gas suena como un caballo primero y despues si se escucha el BOV. Es como un caballo relinchando, o como un pato o una cosa asi. Me gustaria poder contactarte por telefono a ver si asi logras escuchar el sonido y ayudarme un poco con esto. Tu ayuda sera muy apreciada. Ya no hayo que hacer, estoy preocupado.


Sorry everyone...

rotary crazy

^^^^^^^^^^Mi RX-7 esta haciendo lo mismo.^^^^^^^^^^

Lschiavo

Fanman, do i have to buy 2 plugs or 4?
All the same?
