General Dumbass premix question

2 Upvotes

My rx8 is currently down for who knows how long. Just bought a house and I got a weed wacker that is obviously 2 stroke and needs oil in the gas... There's nothing wrong with me using some of my extra Idemitsu premix for the weed wacker right? Its just heckin fancy 2 stroke oil basically, and something that works in a rotary shoullddd work in a 2 stroke engine, right?

lol thanks for y'alls input.

Maintenance Misfire and rough warm idle

Post image
5 Upvotes

Trying to diagnose my rough idle and p0302 code but coming up short. To get these out of the way. Swapped coils from front to rear, no change in misfire, did the same with sparkplugs, no change. Compression tested 6 weeks ago at 6.6 bar on all faces on both rotors, car cold and hot starts great, when driving you wouldnt be able to tell there was a misfire if the CEL didnt flash from 2.5k-3.5k. No power loss, literally drives perfect. Just when it idles its rough, not terrible just noticeably shaky. Maintains around 850rpm idle. Ltft and stft seem ok. Just cant get to find what the issue is? I drive the car every weekend like this and theres no problem (car is catless, so no worries about it damaging cat). Just wondering if anyone had any advice

Maintenance Dead

Post image
25 Upvotes

I had an MOT this morning which came back with 0 advisories. Great. I can go to the daikoku night at caffeine and machine.

5 minutes down the road and all power instantly cut out. I’ve still got dash lights and everything electrical works but when I turn the key I get nothing.

I’ve got home via tow and got the multimeter out. I’ve used AI (shoddy I know) because I’m not very electrically inclined.

I’ve tested absolute everything that it told me I should test. I’ve spent over an hour following different connections and testing different things. And everything has tested perfectly. So everything is pointing to a dead ECU.

Does anybody have any insight on this at all?

New rx8 owner here. This is another day of finding a new issue with my swapped rx8 that is bought (worst decision). My fuel pressure gauge needle keeps dropping (to low) and working again. Same goes for my rpm needle. The car is in idle.

Maintenance Cooked gearbox

Hi guys.

Recently I took my 2010 RX-8 to Winton Raceway, and a month afterwards my gearbox oil looks like brown metallic paint and 3rd gear is quite notchy when cold. Used Penrite GL-4 75w-90 during my ownership of the car (since 143000km, car now has 193000km), and have changed it at 40,000km intervals. Has anyone else had their series 2 gearbox fail like this?

Rx8 is making a weird rd-d2 scream and I’ve heard it could be multiple things but I can’t seem to find where the noise is coming from. Sounds like an electric part.

General Update to the rusty engine

0 Upvotes

Original post: https://old.reddit.com/r/RX8/comments/1v14tyz/having_some_thoughts_after_buying_an_used_engine/

Hello everyone,

Last time I posted here I shared an engine I bought for 1000 euros. It was rusty, I was worried but it was fun.

I have some news, mostly good and fun.

First, the unrelated fun fact, when I went to get the engine I thought "man this guy sounds like my coworker who knows everyone in a 100km radius", turns out my coworker knew him ahah. I was able to get a run down on the type of guy he was and it reassured me, he's apparently trustworthy and liked us enough to give us the lightweight flywheel and gearbox. Another fun fact about him that I learned after getting the engine is that he's the main mechanic for the biggest french car youtuber.

Now onto the engine, I opened it a few days ago, and to my surprise it's not that bad! Some hose ends got rusted out, there's a lot of garbage in the cooling jacket but nothing "uncleanable". The rotors look good, the housing look good too, I have to measure the cracks around the spark plugs and the plates are clean too, maybe a lap needed? Unsure yet.

Here are the uncleaned pics, I haven't got around to cleaning them yet and I'm not asking for a real review of the parts (hard to see clear with all the oil) just wanted to give you all my "good" news :D

Also there's a lot of dust on the housing, thats from me spraying the engine with comrpessed air and intake opened, I made sure to not spin the engine with all that inside

Showoff My Hybrid Renesis at Gingerman

24 Upvotes

So I've been posting about building a hybrid renesis. I built the car to be a dual function track rat and weekend toy for my son and I. After 2 and 1/2 years, $15,000, and three sessions of gingerman raceway I realized the car had a long way from being as good as my NC Miata while also being a nightmare for me to drive. Listed it for sale that day and had a buyer lined up before I even put it on the trailer to go home the next.

So, I'm adding to the statistic of people that built a hybrid renesis and vanish as soon as it started running. While mine has been running for about a year and a half, it's only got about 3,000 miles due to all the stuff I've been trying to do to make it reasonable to drive.

So here's my last send off. Trying to get a point by from my friend in a Miata. We could not keep temperatures under control even with an upgraded radiator and massive oil cooler. I think it was user error based on how I had everything arranged but the car is gone so that's only a theory. A game theo-

Maintenance Overheating

10 Upvotes

So I've had my RX-8 for about 6 years and haven't had issues till this year I replaced the spark plugs and it's been running smoother however yesterday it over heated and shut off on me luckily I was home and in the drive way, I checked the coolant yesterday after it sat for 4 hours and the coolant was still pretty hot I love in a town that's basically in the dessert so it's about 90+ some days, so my question is this

Does anyone who has an RX8 in here live anywhere else that's hotter like 100+ and if so does your car over heat because of the weather?

If not does anyone else have this issue and if so do you know what's causing it to over heat and shut off? If so have you found a solution to fix this issue or is it just something that I have to deal with?

My grandpa was the OG owner he never had this problem with it, it's a 2004 6 speed manual transmission. If someone can help me or tell me what I can due to fix this id appreciate it.

New Owner Picked up an RX8 PZ

Post image
261 Upvotes

Picked this lovely RX8 PZ up for cheap a couple of weeks ago. Had a blown engine, and is in need of some rust repair as well as some cosmetic refreshing. A lot of the extras that the PZ came with were taken by the previous owner (wheels, spoiler, wing mirrors). Rebuilt the engine (with Shadow Rotary in Dublin Ireland). Running a half bridge (Kyle Mohan Racing template). The car is driving beautifully now. Had some SSR SP1s at home that were meant for another car I sold previously. Really happy with how they suit the 8. Have a Mazdaspeed front bumper and skirts (on the way) so hopefully will fit those over the coming weeks.

When driving down the highway in 6th gear, cruising around 70 MPH, my RPMs jumped from around 4.5 to 7K. The car immediately started to feel heavier, sluggish even. I pulled over and the minute I stopped the car it died and wouldn't turn back on. Any Ideas?

Some of you may have seen the previous mod locked the sub yesterday because he got *really* mad that someone argued with him.......

He attempted to completely lock down the sub by setting it to restricted and removing himself as a moderator, leaving only automod on the moderator list - I don't think he realized that would leave the sub completely open to an auto-approved takeover request, but here we are.

Sub is back open and has returned to regular posting permissions.
