Hello, well here is my first techincal dudes , and problems that i have on my car ;
First i want to say that i have very poor knowladge on mechanical world, but i love it and i'm trying to do best with my car ; Sorry if i call something by another name or saying something "stupid". Be free suggesting me, or correcting me anything .
Finnaly i apologize for my bad English.. Correct me if it's necesary .

I'll explain a little about my car first : I have an FD3s , from japan, year 1995 .

It's a single turbo setup, exactly an t78-33d kit , i had a problem with it, because i got it with turbo damaged.. i have did rebuild by myself with an rebuild kit, and now it works better, but it's seems like i have more problems on my car.. I have changed on turbo seals and oil ring, but i think i have the intake turbine whell damaged too (i'll do photos when i'll got new and rebuild it again)

My second problem is that engine dont work very well, i have at the momento 78.000 km on board, i dont know if this engine were rebuilded sometime.

I'll explain symptoms of my bad work engine:
First, my car dont have power.. at the moment i must have like 120 hp..
The car get fire from exhaust.. and smoke white
It start very bad, sounds like 1 rotor is not "working" propely..
When i get out spark plugs, from one rotor are very clean, but from other i have like oil on them..and looks like dont do ignition..

I think that it can be electrical problem, from sparks, that dont do igniticon , or oil seals.. on engine, i dont know, first i want to change side from "bobbine" and try to see how it will change on sparks..

If all will work like before, i 'm thinking to do an rebuild by myself and i'm thinking to take 3mm apex seals, what you think about it? what tools i will need doing the rebuild?

It's recomended to street use 3mm seals?


Well thank you very much for reading

First, you English is just fine. Way better than my Spanish so don't worry about it.

Regarding your car, I'm curious what was wrong with the turbo when you bought it? Did you notice any damage to the exhaust impellers?
I recommend a compression check of both rotors. With a simple compression gauge you SHOULD see three relatively equal pulses on each rotor...hopefully at least 6.5 bar or so. Unfortunately I suspect you won't have three equal pulses on the back rotor.
If that is the case, and since you indicated your not really experienced mechanically, I recommend an experienced rotary shop for the rebuild. 3 mm seals are typically used for higher boost levels and require machining of the apex grooves. I think there also a little harder on the housings.

Hello Sgtblue, thank you replaying me, yes i have damaged exhaust impellers,i'll explain it on image , it's easiest for me :P

I'll take better photos from muy setup.
Yestarday, when i were with car , i have seen that i have powered ecu by jam, and i have fuel control , and more "adds " on my car that i have not seen before..

I'm thinking to do tomorow an rotor compresion check, as you said.

And about doing rebuild, i've found a guy who have an 13b here in spain, with 20.000km reubilded, he want to sell to me with 1500€ , but he sell me all , with turbos, (it's twin turbo setup car, an fd3s) abs, radiator and well, all the front end car.

What you think, it's nice trade?

Thank you again

Sounds like your current engine had a hard seal failure in the rear rotor. When the pieces of the seal exited with the exhaust they damaged your turbo as well. Your engine will need to be rebuilt, with at least one housing and likely a rotor replaced.
Without seeing or hearing the engine your thinking of buying, or knowing what the market price is in Spain for these engines, I can not tell you if it's a good deal. But if it still has the sequential twins you will probably still need some professional help getting it up and running safely with that aftermarket ECU.
Good luck.

Hello Again, Today i were looking for "troubles " on my car, as i said before i have problems with engine.

I thought that problem could come from "coil Sparks" so i were trying to take them out and give them to mazda and check them.

I found some more "problems" First one is this :

If you see, one of them are " broken" . What part are this? what is the function from this piece?

Are this three items, the same ?

And this other thing ;

This looks like "combustion" is not doing well, what you think about , why can it be? I dont know how exacly works in this engine, could some one explain it to me?

Thank you

Those black plastic chunks with the plastic nipples are solenoids. Most of them have no function when the car has been fitted with a single turbo. Most folks who convert to single turbo remove these lines as they are unnecessary and can cause vacuum leaks.

I am a little concerned that the single turbo installation in your car is not done with adequate supporting systems. The fuel, cooling, and ECU systems must be upgraded for a good single turbo upgrade. If the original installation did not remove the excess solenoids I wonder if they got the other important things correct. You may have quite the puzzle to solve if the original installation was not done accurately and knowledgeably.

The black stuff on your throttle body and upper intake manifold looks like oil and dirt. Verify your air filter is in good condition. I think the amount of dirt and oil is due to having turbos with blown seals.

I agree with Sgtblue, verify that your engine has good compression now. There is no point in rebuilding turbos if you bolt them to an engine with bad seals.

Hello , as you suggested me i am taking off the motor and i will try to repair it ;

Here is some photos of it , feel free to suggest me things with it : )

Well, i have a few questions ;

First one i want to improve my "single turbo setup" , starting with selenoids, do i need to remove them? i have 6 in one line of them.

The engine need to be rebuilded, but, 2mm seals, or 3mm seals?
i think my car will get arround 400 hp. Which one is better?

I'm thinking to get some rebuild kit from atkins rotary, do you know some another provider? or shop?

I need to do that my car take off less CO2? is it possible? maybe with secundary injection? water injection? if it's impossible is there some way to reduce them for a hour or like that? This thing is for European inspection ; i dont know how to explain. It's a rule for circulation

What can i improve on my engine ?

Is my Clutch a Stock clutch?

Please feel free to suggestme any modifications, or addons , or all that you think that can be better for my car , i want to get it ready and reliable now that i taked off the motor.

Thank you very much for reading and best regards.

Dude that clutch is a very aggressive clutch, your stock clutch is a complete circle and the one you have has 3 pieces. This clutch is known as a 3 puck clutch, there are also 4 puck, and 6 puck. Within these clutches they could be two different types, solid hub or sprung. You have a 3 puck sprung. The spring makes it easier for the clutch to engage, and ultimately to daily drive it.

Anyways I have a very similar problem to you but mine is twin turbo, and am in need to rebuild my engine also. You say you are not that great mechanically, dude your better than 90% of people I know.

Hello Carlos, thank you for your advice about my clutch, i were thinking about change it, but i will drive it as it is ;

In fact i'm serius, i'm learning now about mechanical things, but thank you for your comment.

If you need some help with your setup, or engine , ask me anything, and i will try to help you ; are you from europe?


Best regards Lobito

curbina43

No I am in the US Army stationed in Germany, but originally from Honduras. Ireally appreciate your offer cause i need help too. We will keep in touch to see how we can help each other out.

Lobito

Here we go with some more piks about my job on it, as you can see, i have a big problem with one rotor house..and with all engine xD

Yep, that would be a bad housing.

So what are your plans?

Moving this so you get more experienced eyes

I'd definitely explore the option of another already-built good engine for 1500 euros.

looks like the one rotor that was running was burning coolant for awhile.

ShiftRX7

Just be sure on who rebuilt the engine if you're gonna buy it and test it...you don't want to end up spending 1500euros for an engine that still has issues.

Old motor...RIP

Hi guys, i were speaking with guy who wants to sell motor here in spain, and the motor have been sold yet..so i'm looking for some aftermarket motor, if you know someone in good conditions, and reasonable price, feel free to suggest, pm, or whatever you want : )

I'm thinking to add reliable mods, like water injection, what you think about? maybe 50/50 ethanol? or maybe with alcohol? ..

From my motor i think that i can "take " one rotor, one house and some more parts..

I need to know too, about the difrence in "2mm seals" and 3 mm seals..if someone can explain it a little i would thank it.

Best regards, rotary Lobito << XD

Para ser una persona que no sabe de mecanica, esta haciendo las cosas de lo mas bien. Te recomiendo que cambies el turbo tambien. Si tu tiene que hacer inpension the emisiones, es difiil hacerlo con un turbo por que tienes que cambiar los injectores.

Their emissions are alittle more relaxed out there than here so he might be ok. And yeah I was surprised to see how well hes getting all this done also considering he claims to have no mechanical experience.

BTW I'm Puerto Rican so I can't write back in Spanish, I can only read it haha.

Buenas ; ) gracias por los comentarios y por vuestra ayuda, realmente estoy tratando de estudiar duro para acabar de entender todo mejor,y de mejorar mi coche, en estos dos ultimos meses me he comprado bastante herramienta y he ido haciendo poco a poco .

Voy a traducir :P (no quiero parecer mal educado xD)

Hi , thank you for your help , i'm trying to improve my abilities with mechanical things, and learn about rotary at maximum, it looks very intresting at the moment, and i love my car so i want to get it done as fast as i can..

I were thinking about something a lot, may i buy a Power fc ? i have a stock ecu modified by jam sports..(from japan) but power fc with commander looks gr8 and useful, what you think?

Thanks again and best regards rotary Lobito :P
