why? He can def get it to work ... OP do you still have the blockoff plate from the kit for the APV?

APV runners do not have injectors on them.

OP, get a 6 port LIM, block off the APV, take out the sleaves ... drop in the 4 yellow injectors and you should be good to go

so this is what you need to get her running:

6 port Lower Intake Manifold (or you can try to add injectors to the existing 4 port one, but that would be more risky and more expensive)
M/T fuel rail (for 4 injectors)
4 yellow injectors
Greddy Block Off plate (should have come with the kit) (this is actually kinda optional, but I would recommend it)

I may be picking up a blown engine longblock this week, so I can sell you the injectors, LIM, and M/T fuel rail for $250 shipped plus your pair of blue injectors (you will take them out anyway)

Please let me know soon as I prolly will not be able to pick up this motor if you do not want this stuff.

PS: I'll be getting the wiring harness with it too, but I am not sure if you will need it, if you do, I'll throw it in for another $100 shipped

 

, you think he can manage that?

 

I mean this in the nicest way possible... the fact that this situation exists is very stupid and I hope you learn something from this.

Do more research on a car before buying it, especially when there are significant modifications. Also, keep better records on stuff like this. There's really not a good reason to not have a way to get in contact with the previous owner about this situation.

Hopefully you can get this sorted out and have it running like you would like. Good luck getting everything sorted out, but be ready to try and part it out if it's looking like too much of an investment.

 

I hope he can ... its not much harder than putting the turbo in

 

I suppose that could work... Its still a waste of time though.

He wont be able to upgrade the kit and will forever be at stock greddy power.

Quitting while your ahead seems like a super good idea.

 

I can't see why he couldn't just wire the injectors so that he has P1s and secondaries and tune it . Should work just fine but may need bigger injectors.


No real drawback having a 4 port engine running with the greddy kit IMO .


What is the current injector setup (clours) and which ijectors are wired to which positions ?

 

He can still up the power IMO ... he can get away with running smaller turbos and having them run in a better efficiency range, I suspect that this is why the Greddy kit originally had the block off plate.

Remember, his exhaust ports are still the same, the intake ports are a different story.

I just cant figure out how this car was running with the 6 port ECU, it should have been quite lean up top, if they set it up the way I think they did


I disagree, at some point the missing 6th ports will start to become a restriction, yes.

However, I think that restriction will only rear its head (become a big enough nuisance) once he is pushing 300+ rwhp

 

heres the list of everything done to the engine as i have it
4 port renesis stage 3 ported rotary
cobb accessport
Greddy T618Z
Cast Greddy manifold and downpipe
Greddy 31V FMIC with polished pipes
Synapse Sychronic BOV recirculated
Mazdasport upgraded intake
Racingbeat exhaust
RP supercat Midpipe with gutted cat
ACT prolite Lightweight Flywheel
Exedy stage 1 clutch
rx7 plugs
Walboro 255 fuel pump
480cc primary, 650cc seconday injectors
custom upgraded fuel rail with adjustable fuel pressure regulator
Innovative LC1 wideband
AEM meth kit
not sure if that changes anything but at this point its figure something otu quick or sell it.. i just found the shop that i was told built the car originally so im going to call and try to see if they have any ideas either

 

I am 100%sure that you can get it running if you get the 6 port manifold. And that way you can get another pair of injectors too.

 

Also i bought the car how it sits now.. i didnt put the turbo kit or anything on or take anything off

 

OR you are going to need an A/T ECU along with matching keys and I am not even sure how that would work with the M/T

you may also need a different Cobb AP, I am not sure, but MazdaManiac would know


OR

you can part out the car, and put a 6 port in there


Out of curiosity,
how much did you pay?

 

and they are?

 

Defined autoworks in Columbus. I talked to them and they told me that they could change the ecm and tuner to a microtech and that would definitely take care of the problem. He said he told the original owner that but he didnt do it. Are the microtechs reliable?

 

As reliable as a married man in a brothel with $10,000.

 

damn....

 

Have you asked them why you have a 4 port engine?

 

Best idea
1. get full coverage insurance
2. have friend drive car off a cliff
3. report car stolen
4. wait for cops to find totaled car
5. pay deductible to insurance company
6. but another unmodded car

J/K good luck...

 

I suppose it would be too logical to find and install the proper engine into it rather than dig the outhouse hole deeper ...

 

I think you may have a 4 port manifold installed and your engine IS a 6 port???

 

Um, nope. Think about your statement for a sec.

 

But it wont have stage 3 porting!!!

 

^ I spit on my computer screen ... thanks shady!

 

I wonder what would happen if the injector flow rate for the P2 injector was just set to 0.0. In fact it I think it'd be worth a shot, considering the options.

Most of the differences between ecus are just in the calibration, and the code is the same. For example, MT ecus still look for a message from an auto trans controller indicating gear selected, and will use it for picking which open loop map to use, it just never gets that message.

Since the ecu is calculating the total mass of fuel required, it might try to reach that quantity with just the primary and sec. I should look at a 4port rom again...

 

Good lord, wtf was the previous owner thinking? I guessing either he be stupid or cheap.

Like others who have posted, either replace the motor with a True 6 port, or keep the "go fast" parts (turbo, Cobb, ect) and get rid this cars hybrid setup.

If it was me, replace the motor with a 6 port and sell the 4 port. you will be much happier in the long run.

 

these are the guys that put that engine in that car?
