first off i have a 2004 rx8 gt with a greddy turbo properly tuned. I was driving my car and i stopped at the gas station and when i was leaving i shifted to first then second then third and then it died. i checked spark, compression, fuel, replaced coils, wires, plugs, and fuel pump, when i try to start it the engine wines then backfires a little. I cannot get it to start any help would be appreciated.

 

much more info needed.
Mileage? Turbo mods? Properly tuned, by whom/how? Any other mods? Etc...

 

Grand touring 75000 miles tuned by greddy in boston
MODS: greddy turbo kit, greddy intercooler, greddy pipeing and cuplers, greddy bov, greddy e manange ultiment, greddy pullys, greddy oil pan, greddy exhaust manifold, greddy intake, ageny power cat deleate pipe, borla catback exhaust, weapon r oil catch tank, msd wires, and a/f computer star 2 way pager alarm system with lcd screen and remote start.

 

not a turbo expert but e management is not a good tuning option from what i have read. how did you check your comp #s?

 

How many miles have you had the turbo on, are you running a boost gauge, A/F gauge? do you have a blow off valve? do you have any of the greddy fixes done to the kit? Are you running the stock ignition?

Etc Etc...

The stock greddy kit is complete and utter ****. Luckily it only takes about $1500 to make it a proper one.

 

^Doesn't sound like the OP knows what has been done to the car. Just a list of added parts.

OP, try reading through the Major Horsepower Upgrades forum. Pay particular attention to the stickies.

 

Yea I figured that I just wanted to point him in some direction.

 

yeah i bought the car because it wouldn't start and i called the dealer it has a re-manufactured engine done in nov 2007. I put a compression tester in all of the spark plug hole and none of them are jumping the needle. followed the method here.

 

i have the engine out now because no compression. should you be able to turn the eccentric shaft by hand freely? our should it build compression? i am new to the rotary world as of monday.

 

Impossible...

You did the test wrong, unless you poped several apex seals.

Did you hear any loud noises when you made that 2nd to third shift?

 

None of the faces jump the needle?
Did you have the spark plugs in all the holes except the one being tested?

 

It should be fairly hard to turn the engine even if all the seals are destroyed... but I kind of think you are trolling at this point.

 

yes i did have the plugs in. i used two different compression testers to make sure one was not bad. both read zero. i also had spark, and fuel. like i said i would roll the car over and not get anything. every now and then you would here i would get compression and back fire. im not trolling anyone. like i said i am new to rotarys. also with the plugs out and rolling over nothing push out the hole. and you also couldnt hear it fire it the engine. it sounded like this.

 

It's a bit unusual for none of the faces to show compression... there are 6, they can't all fail at the same time unless there's a hole in the block. If you weren't in 4th gear when it happened, I'd say it sounds more like a flood... Are there any CEL codes?

What do you plan to do now that you have the engine out?

What fuel pump is in the car? Do you hear the fuel pump working at any point while cranking? They're known to fail you know..

 

the battery died but it popped up with misfire cylinder 2. and i am going to check the apex seals. i replaced the fuel pump. still nothing i have tried all of the deflooding procedures with no luck.

 

so i have the engine out and i am waiting for a bigger impact to show up to remove the eccentric shaft bolt and flywheel bolt. i have posted a video of the finding through the spark plug hole. The reason it had no compression. This is a re-manufactured engine i guess was put in by the dealer.

 

Holy **** dude...

You poped several apex seals without knowing it.

That sucks man.

 

the engine is scorched time for a reman

Yeap, once that apex seal pops that is the end of the line for that engine.

you might be better better off getting an engine from a builder, sometimes those mazda remans fail quickly.

I only say that because I think you are out of warranty. If you are a engine from a quality builder would be the best route to go

Dam that is baller dude.

 

I'm more surprised that you didn't even realize a the seals were fawkered!
I cried after that video...

Just to recap- you're positive it was properly tuned? What boost were you running?

 

I doubt he had a boost controller most likely it was hooked up directly to the WG so 7 psi.

 

i believe the computer has it tuned to 5psi

Without gauges for FI applications, you're pretty much playing with fire
