The Greddy Kit is 100% plug and play engine management. No wiring of any sort. The custom wiring harness Greddy made is a peice of art.

well i dont know if "nice" is the correct word..... but it did get us around to the resturant pretty well and its got a Turbo....... :p :D

 

In stock right now: 1989 Dodge Caravan turbo, 1999 Mazda Miata getting a supercharger in a month or two. Previous cars: 2000 Mazda Miata with GT28/35 turbo, 1988 RX-7 SE with Turbo II conversion, 1987 Mazda RX-7 Turbo II, 1993 Mazda RX-7 Touring with upgraded twins, 1993 Mazda RX-7 R1 with GT35R, 1994 Mazda RX-7 rolling chassis and had a 3 rotor block but never put it in before selling it, 1989 Dodge Caravan with chrysler 420A engine and custom turbo kit (current van is stock block turbo), 2001 Ford F250 turbo diesel.

 

Whats the chance the work CZ did on his re-packaged eManage/Greddy/Trust unit fed back to them for a production unit of their own?

We made our own one for the TSI unit, using the OEM connectors. Took a few hours, like a few too many! :D

Cheers,
Hymee.

 

Dayum. Turbo Lord!

 

Uh, you think? :p

 

I wnt and read the instructions forthe kit and see what you are talking about know. What was the talk about the injector setups(on the emanage), did you have to set yours with the kit or did it already know what to do.
How about jeff. did you have to do anything difficult to get yours setup? Im trying to decide which way to go.
Also could i do it with out a lift. i have all the tools(used to be mechanic) but no lift.

 

Jeff, I pulled the manifold off of brillo's car today and compared it to the pdf file you posted. It didn't scale properly. The pdf is actually a tad smaller but too much to be able to be made to work. I made a copy on paper and then held it up to the engine and got the exact port sizes and shapes. They are MUCH smaller than the scan. It's strange that the gasket has huge port openings, the engine's are small, the manifold's are larger than the engine's but not as large as the gasket. Then after the square opening in the manifold, it goes to a round pipe with no taper. WTF??? You had to have been thinking the same thing.

 

Yeah, the stock manifold is odd.

 

Yeah, I'd say most of the people in the shop were standing around going WTF? when they saw the ports. We took some good pics which will hopefully make it clearer why the exhaust flow sucks.

frankly, I'm amazed you can fit a turbo in that spot near the engine mount.

 

Any updates on the project?

 

Uh, its done and I love it?

I guess I need to get off my butt and actually make a complete install thread...

 

Oh ok... if you could it would be best to. I'll make my own kit soon

 

Do you suppose it is this, rather than the "high quality design" of the stock cat-back exhaust that is responsible for the inability of aftermarket exhausts to significantly improve horsepower on an otherwise stock car?

I'm left wondering why. Mazda decided this was optimum for some reason - I'd love to know what it is.
It isn't financial, because the type of manifold they went with is not cheap.


As am I! :D

It was a tight fit and I spent the single largest amount of time on the design there.
The smaller turbo that Greddy uses is much easier to fit. My T3/T04 has a much larger compressor, so I had to play with all kinds of angles to get it to fit, yet drain oil correctly and make it possible to get air into and out of the compressor in a useable direction.
Everything is a compromise.

Its was probably emissions related, like everything else on the car.

 

Probably. Smaller ports equals higher exhaust velocity, yeilding quicker CAT light-off.

However, bigger exhaust ports would have probably only netted more peak HP, not a lot of power in the "driving" band, so why bother on a production car.

 

Jeff, did you get your EO-1 working yet?

 

Yes. I am still playing with the gain and start levels to see how far I can push it before I get spikes, but it does control the boost now.
I was just stupid - I left one of the caps on the solenoid as was suggested by Jon, Mohd and a bunch of other people.

Do you still have an unresolved CEL? Have you started the turbo install?

 

Picking the car up on saturday. They got a head mazda guy to come out and look. The whole time I have been getting the CEL's was from a TSB. The one about clearing the ecentric shaft sensor. So I got a free motor :D . I cant imagine the dealer replacing all the stuff they did because of this. Oh well worked out good for me. New wires/plugs,and coils all new plus a motor! Good ol mazda

 

Holy sh*t. The whole thing was just the brake-stomp TSB?
That would have been the absolute FIRST thing I would have tried.

 

Yup, all because of this

I just assumed they had tried it on the first attempt. Oh well we will see what it does the next few days. :p

 

Here is the most current E-Manage MAP for anyone that might need it.
It is compatible with the Greddy kit as well as any custom setup that uses the same injector wiring scheme.
This includes NVCS control of the open-loop dongle (standard on the Greddy kit, though I suggest removing it if you have hesitation issues and a lot of back-firing under load), the acceleration MAP and ignition timing control (which is not standard on the Greddy kit).

Mazdamaniac,
I think thats a great idea I thought of that before alos but I had to leave the states for a while and mt car is in storage(I'm a soldier). I know there are ways to make this sing they just have to be experimented. I learned how wankels work back in vo-tech but never had or toeyed with one. Also, it rubs my rubarb how no ones doing anything in the magazines with thr rx-8 looks kinda discouraging, seems hopeless for now but I'll be doing a lot more after my waranty expires haha! Good luck

 

There is another RX8 project that is almost ready for the street with a custom turbo. In this thread you will find information and some pictures, https://www.rx8club.com/series-i-major-horsepower-upgrades-93/can-i-boost-rx-8-500-hp-56057/. The blue RX8 did 391 WHP and the red one did 276 WHP with a greedy turbo. I confirmed this information with the owner of the red RX8.
