Title: Bad news... Engine went popped
Post by: yiug412 on July 25, 2011, 11:28:13 PM
Few days ago driving on A6 in 5th 6000 rev, sudden lost of power and got the car towed back home.
Today I did a compression test. Rear rotor lost compression.... :(

No sign of tip failure at all before, always started hot or cold first time, I thot the engine is healthy... :2Rolleyes

Due to me moving to MEng I cannot afford to spend more time on it, it had been on the axle stand for 3 months getting all foot work and other things surrounding the engine sorted for the car. At the end the engine let me down.... :(

So I will be breaking the car when I\'m back from summer job. Should i get a S2000 or RX8 for my next car? I\'m looking for reliability as this is my only car and i really have to get to lectures next year XD

Feel sad to leave the FC section here. You guys were so nice and helpful here, Thanks for the help through out my 14months of ownership of this car :)

Gutted for you mate, get an RX8 next and keep it in the family lol.

Do let me know when you break it though, I\'m sure you have a few goodies I could benefit from :Giggle

Erm reliability... remind me what has just blown up ?

What does your car share with an RX8 ?

There is a reason (well several) why RX8\'s are cheap and they are all to do with the engine.

A well maintained one should be reliable though, in theory lol.

you not just fancy dropping in another engine ?

how much are you looking for the car in its current state ?

Thanks guys :)

Wont be dropping another engine as if im rebuilding this to the spec i want, it will cost around 4k. I will be breaking my car and im happy to take offer for the whole car. It\'s just the rear rotor blown and surprisingly didnt hear the scratching sound at all. can upload the video of it doing the compression test if anyone interested. Spec list is in the for sale section :)

The thing is I will be going to Hong Kong for my summer job for 2 months and back in Oct >< so wont be available for breaking till then but WILL BE available anytime to be towed away if anyone wants this car and put a new engine in it.

4 wheels, steering wheel.. fuel tank.. chassis.. i can go on.. all quite common on 99% of cars :Giggle

 XD :cheers

btw quoted from wiki

The engine entailed two major changes. First, the exhausts ports are no longer peripheral but are located on the side of the housing, which allowed engineers to eliminate overlap and redesign the intake port area. This produced noticeably more power, thanks to a better compression ratio. Second, the rotors are shaped differently, especially their side seals and low-height apex seals, which offer optimized lubrication.
These and other innovative technologies allow the Renesis to achieve 49% higher output and dramatically reduced fuel consumption and emissions (the RX-8 meets LEV-II). It won International Engine of the Year and Best New Engine awards 2003 and also holds the "2.5 to 3 liter" (note that the engine itself is 1.3 liter) size award for 2003 and 2004, where it is considered a 2.6 L engine.[3][4] Finally, it was on the Ward\'s 10 Best Engines list for 2004 and 2005.

So it is quite different. being new and non turbo hopefully it will last me through my other 3 years of masters and placement :p

I don\'t look at the RX8 as an unreliable car :)

I think there are a few things that tend to \'go\' so if you replace them, you\'ll have a good time :p

Rx8\'s are big bucks to run and maintain (tax is £400 a year i think?) and the engines do tend to go pop, and not in a cheap way. However, low milage ones are pretty darn cheap. TBH if you\'re want a sporty car i suggest you rebuild the fc instead. You know the car and whats likely to go wrong, the chances of you getting a banger of an rx8 are fairly high, specially as owners don\'t always tend to be rotary enthusiasts. Additionally you\'ll have a nice new engine in a sweet car

Its still a rotary, it still drinks too much petrol and is massively less reliable than a piston engine.

I just sold my wife\'s Audi with 170k on it still on original engine and turbo - how many Rotaries can do that ?

Rotaries have some advantages but running costs and reliability aren\'t in that list.

Pre=March 2006 RX8s are £260 a year tax.  A well maintained one is very reliable, do a thorough test drive and get a compression test before buying, and there are plenty lasting 100k + on original engines.  By that age it\'ll probably be on its 4th Catalytic converter if the owner hasn\'t decatted it and is keeping a spare cat for the MOT!

depending on rebuild cost, i thought baout shipping a used block from jap. cheaper than rebuild but most likely gonna be buying twice but if u can do engine swap yourself then is not really a biggie lol
maybe pot luck 3rd engine will be either low milage or rebuit and ported and a bt of a monster lol

So you are going to buy a more expensive car instead of the cheaper option of replacing the engine in the FC?

*has spare bridgeported engine in garage* :D

Post by: Will66 on July 27, 2011, 10:29:57 AM
It would be cheaper to stick a new motor in your FC than get an RX8.  Perhaps m1tch is open to offers on his bridgeported motor? :)

If he is then he\'s a fool! But there is a 13B turbo on eBay for around £700?!

Perhaps m1tch wants his bridgeported motor for perverted purposes however it would be a shame to break your FC for the sake of less than the price of any other decent motor you could find for a rebuilt engine.

As much as i\'d like to purchase bits of your car when you break it.... Will is right, plus the work and effort and money you\'ve put into it will all be for nothing if bits of it end up all across the country.

And you know there is that part of you thats saying.... "you should rebuild it man."

I say rebuild, you can make it better, faster, stronger, you have the technology... but I also agree that I\'m circling like a vulture too lol

Brand new crated RX8 engine is about £3K - and one has been fitted to an FC :)

Renesis engine in an FC?! That would be like an egi but fast, awesome!!

I vote do that if your against rebuilding the 13B and want something different.

I believe that with the 6 speed RX8 gearbox the gear selector is in a slightly different place vs the RX7, so the gearstick won\'t be central like OEM.

Hell for a n/a FC with 230bhp and 6 gears, can probably compromise with the gearstick location :Giggle
