Rickkkkkkkkkkkkkkkkk?

Ok, I've got a few more things done to the car. Didn't mean to take so long. Finally got the larger secondary injectors installed. Went with 650cc ones from RC Engineering. The primary injectors are stock. I enclosed a picture comparing the stock injector to the RC injector. Just finished most of the fuel re-mapping. Duty cycles are down to about 85% now. Still need to fine tune it on a dyno.
The drivability is almost as smooth as stock. I had my wife use the car to run some errrands, and when she got back she said it felt like a turbo RX7 now. Much more responsive.
I was a bit concerned about how well the transmission will hold up when shifting at full power. A friend at a transmission shop told me about a device that will allow you to raise the line pressure in the transmission, thereby applying more force to the clutches. The picture of it shows that you can adjust it from in the car for best performance. The unit is made for a 1993 RX7 transmission, but the RX8 one is from the same family. It goes on next.
I have enclosed some other pictures including the 1993 RX7 blow off valve, my nav display showing boost and water temp gauges (HKS CAMP), my canscan from the laptop on the car display, as well as one from the e-manage software showing injector duty cycles. It is a bit hard to read the smaller text, but it is easier than looking down at a laptop screen when driving.
After the dyno testing and transmission pressure device are installed I will let you know how it turns out. But for now, with the turbo install it makes driving the car way more fun.

couln't get the last picture in.

Oh Hell Yea !
Sounds like its time to buy a Greddy kit before the price jumps up to much.
With the raised pressure in the trans, will the "clutch rings" wear faster?
Is there a downside to the higher pressure?

From what the transmission shop owner tells me, there is less wear with the increased pressure because the clutch bands won't be as likely to slip. The pressure increase is applied only at full throttle. The downside would be that if you have the pressure too high, you will get whiplash when the transmission shifts. You want the shift to be firmer, but not harsh. I will know more about this when I get the unit installed on my car.

Very nice.

Very impressive.

I wonder how much power he's gotten up to?

RWHP?

Rick how many psi are you planning on taking GReddys kit up to w/your automatic?

For now I don't plan to take the boost over 7 psi. I may change my mind after I dyno the car. I hope to get it on a dyno within a couple of weeks. I don't think that there is enough fuel flow capacity with the injectors I am running right now. (stock primarys and 650cc secondaries).

Rick basedon how your car is responding to the GReddy kit - do youthink our automatics could handle the more powerful SSR turbo kit? Or would installing that kit require us to replace too many parts (for stability sake)?

Apex8, where did you get the pressure riser unit? Online dealer?
Thanks.

I just wanna know how much total is this whole thing costing??

Pimp in da Rx8, how do you get the button tufted diamond shape back window thing to work on the 8?? :confused:

Please tell me you also installed an auxilary transmission cooler...I'm assuming you did since their only about 50 bucks (for a stacked plate) and make a huge difference in longevity, protection, and performance.

In answer to some questions -

JeRKy8 - don't know yet about reliability - this is the first automatic Mazda I've hopped up. Time will tell. Heat is probably the worst enemy.

Crossbow - I plan later this week to add an additional cooler on the right side of the front end per the transmission shops reccomendation.

bxb40 - the pressure riser came from www.superior-transmission.com.
They carry lots of interesting transmission parts.

Will update later after more testing.

Rick

Ok i have this engine but not on a Auto box (not avalible in Europe) so it should be alot easier to fit right?

apex,

Awesome. It makes a really big difference. Have you taken any temp readings? Both the 6i ATX and the 6s ATX's (jatco not the new 6spd) have overheating issues on stock setups. I'd imagine the 8's 4spd probably is overheating a bit from the factory as well. You'll know instantly if your shifts improve with the cooler. (If it was overheating or not).

If they do, please start a thread for your fellow members, so as to prevent premature transmission failure around 60-80,000 miles. Tranny coolers are so cheap and easy to install, but are often overlooked as a modification. Most people don't realize how big of a difference they can make in the longevity of a transmission. In most cases they can more then double the lifespan...all for less then 50 bucks.

Considering the cost of a new ATX + labor, an Aux ATX cooler (stacked plate like B&M or Hayden with pressure drop protection) should always be one of the first modifications to an ATX equipped vehicle...regardless of power. As long as you run it inline with the stock radiator cooler, it won't effect the warranty in any way.

any new developments on this front?

what about the 2 extra air ports that the 6-speed has. wouldnt that be a factor in all of this. When i spoke to greddy, they said that they would think about working on a kit for the auto but they only were only going to release the kit for the 6-speed for now.

The thing is, if I remember correctly, they've already designed a system for the auto. They just did it for Re-Amemiya.

i think the one in japan trust(greedy) have the kit for auto... i haven't install that yet.. but i will found out after 20,000km after everthing run smooth...
but i heard that u only max boosting is 9psi

Its been almost a month since Rick has logged on and posted something here.. :confused:

What is there for him to post? He installed it on his car, programmed the eManage and everything works great. Long term reliability info isn't something you can glean after one month. Not everyone is compulsive about posting every tiny detail.

I was under the impression that hewould be posting a time slip/dyno soon. Id just like to know exactly how much wheel horsepower Id be gaining by purchasing this kit for my automatic and Imnot talking about estimates either.
