Is there anything that can be done about the headlights? Its so annoying to have to constantly clean these cause they bake the dirt. What are my options besides replacing them?

 

Anyone can recommend me a junkyard in the states that they have R3 parts for sale and can do international shipping?

 

I recently started having slow hot starts with my rx8 and power loss going up hills. Because the engine is a rebuild I immediately knew to take it and have it tested for compression, however nobody in my area has the mazda tools and I am not a car person. The mechanic tested it with a standard cylinder compression tool and measured 3 readings between 40 and 50 psi, at 300rpms. The guy who sold me the engine is in a different state and had a 2 year warranty on the engine, but I have 2 weeks to get it sorted before the warranty expires. Obviously he doesnt want to pay for a new rebuild, and I dont want to pay to ship the engine to him and have a mechanic pull the engine for him to tell me something is wrong that was somehow my fault. (I.e. I did not premix)

i guess what my question is...is that I am SHOCKED that the car starts at all with such low compression numbers. My last engine was one that had 8 separate owners. Lord knows what it went through. It had numbers in the 60s to 70s range and refused to turn over, even warm. This engine has worse numbers and somehow performs better? What could mechanic be doing wrong with compression test? Is the analog method completely bogus?

 

What shop is the warranty from and can you contact them directly?
I agree that at 40-50 psi @300rpm it shouldn't start at all. Who knows what he measured wrong, but you're still having hot start issues and that sounds like grounds for warranty claim.

OJ Imports. The car starts hot but is a slow start and has an uneven rev at idle. It JUST had difficulty going up a hill a few days ago.

the issue is that I may have to pay labor to pull engine again and ship it to have him give me trouble. Thanks for your fast reply

 

I have contacted the owner at OJ imports and he has been very friendly with helping me troubleshoot, but it is difficult because closest dealer is 5 hours away and I was instructed not to put miles on car with engine acting up.

 

Seen another way, you'll still have to pull the engine and ship it after the warranty ends, so unless his troubleshooting points to things that aren't the engine, may as well get started. Where are you located? Maybe there is a rotary shop closer.

 

I'm really not mechanically inclined enough to do an engine swap. I'm mechanically inclined enough to change a CV joint and a starter. I'm thinking if it is an engine swap I am likely to sell the car. I'm in southern Colorado.

 

to be fair it still remains to be seen whether there are other factors, but others didn’t do so well with this builder when it came to warranty.

The point to emphasize is that a proper Renesis engine build for long term durability is not cheap. Paying heavily is no guarantee either as there are details involved that make this engine unique over past rotary engines as well. Even the Mazda reman supplier doesn’t always do the best job. Unfortunately there are fewer and fewer people you can trust to do a good job for a Renesis rebuild.

Hopefully this might be a result of other mechanical issues; bad/clogged cat converter, fuel pump etc and the engine is ok once properly compression checked.

You gotta be careful with warranties. I have seen warranties with fine prints that mention they exclude rotaries and diesels, so whatever paperwork they give you, I'd double check.

 

One other thought: you could check the engine vacuum at idle. If the engine is really down to 50psi, you should be below spec in vacuum. That's an easy test any mechanic or you yourself can do.

Team is right, we can proceed by eliminating other causes: ignition coils, catalytic converter, fuel pump. Is this an auto or a manual?

 

Stupid question. Looking to get Mazdaedit. I can only find it on epifan software, and the plug in on a separate site. Just wanna make sure I'm looking at the right thing

 

Automatic. Mechanic got back today and said one coil wasnt sparking once car turned over. Hopefully replacing coils will improve performance and his compression check gauge was bad. Next would be cat. Car had mazda recalled fuel pump replacement and coils were done at the same time.

 

Hello I'm new to this forum I've read it a lot but just started posting. I have no clue on how to create a post myself, but I'm having trouble with my rx8s I've been working on mine for some time its a 2004 manual 6 speed all stock with front air I think its called the VLAD. anyway I got this car about 4 months ago and I've fixed it all to the point that I've put 2000 miles on it and it fires right up, or it did.... now I'm having issue with it not firing up. it seems like the injectors are having issue priming. the pump is new, and primes just fine, but now it will not fire up until I turn the key on and off and prime the pump multiple times. I've cleaned the ssv and replaced the solenoid. I've de-carbed the motor and changed the plugs, coils, and wires. it really seems like an injector but I wanted a second opinion before I broke it down again. once it fires up it runs fire and there really isn't an difference in hot or cold start. let me know what yall need info wise. I am a mechanic just not a master so I need help sometimes

 

Are there any easy places to tap into the reverse switch in the front of the car especially near the head unit?
As an aside I really wish people didn't use imgur or photobucket on here. I have been looking for several hours for an answer and 90% of the posts are answered with "use the search" and the other 10% have links to images on imgur that don't exist anymore. If you read this, from now on PLEASE upload images instead of linking them...

 

the reverse switch in the motor or the bolt on the bottom of the tranny? my wire got cut before I got mine and I had to practically bear hug the tranny to get to the wires then I just pulled off the bracket on the frame body and pulled the wire around far enough to reattach it.

 

The wires are in the engine harness and they run across the top of the engine and transmission... there is nothing inside the car. It wouldn't be too difficult to run the wire down the shifter boot area.

 

There must be then at the very least a wire going to the reverse bulbs on the tail lights? I'd rather keep it in the cabin if possible.

 

As Dan said, it’s right near the shift tower on the top of the transmission. You just run the wire under the shifter boot to that point. It’s way easier than you’re making it out to be.

 

I looked around for the answer to this question, because I'm sure it's been asked, but I couldn't find the answer.

I bought an '04 RX-8 SA that came with an extra motor and trans (because I can't say 'tranny' anymore)
One motor has been diagnosed with bad compression, The one in the car is, as yet, untested. (I been busy!)
Anyway, If I decide to do a rebuild and I tear apart the extra motor, only to find one rotor housing or one rotor is FUBAR, are the rotor housings interchangeable from front to rear? What about the rotors?
I'm asking if I can put a front housing or front rotor in the rear position - in the event I have 2 motors with 2 bad front housings, etc.
*Disclaimer* - never have I ever taken a rotary engine apart, busting my cherry on this one.

 

is having all green fuel injector making my car start slow
​​​​​​

 

wish I was joking

 

Green injectors from what? How did they get there? If they aren't OEM for the motor they will have different flow rates than stock so you would need an ECU tune at the very least..

 

I put this motor in myself and whilst checking out the engine i saw mismatching injectors nd had spares soooo i thought it made sense at the time to have them all the same color something jogged my memory about it but the car wont turn on unless i give i help it with gas so maybe? ima switch them today and test the fuel pump

 

The car will not run properly and may be damaged if you're not using the injectors that were meant for it. There were never any green injectors.
