Hey guys...
My rx8's kaput already clocking at 110k mileage.... currently considering to change the engine.... the budget is 15k (stretchable to 20k)
already when to ah choy subang for his advice...
brand new rx8's engine is 25k...
rebuilt is around 12k..
change to halfcut engine around 15-18k...

i'm also considering to swap to piston type engine such as 1jz or sr20det.... bcoz rotaries does need more maintenance and can run only on ron97...

any suggestions n opinions are very much helpful... thanks... notworthy.gif

back when first got the car , noticed that the engine temp would rise during traffic jams .s. had read that engine would tend to heat up in traffic conditions or hard driving so left it ..then after cny last year , driving to KL from PG , just before ipoh , there`s a section of the higway which goes up slope before the tunnel ... got caught in a massive jam , the engine temp had risen to maximum ( i know my mistake , should have pulled over and let it cooled down ) , reached the tunnel evrything cleared up and went back to normal ... reach KL already , suddenly the car stalled, but after a while it started back up , the quickly drove back home ...few days later noticed the temp still rising ...so masuk workshop (st wangan ) dianosed driver side cooling fan motor kong ... but i think by then the engine was damaged bdly ... lol sweat.gif

i only changed after the ah choy took apart the engine and showed me the parts which were err...serisouly needed replacement ... worse part was the e-shaft bearing ... worn down till you can see the copper/brass color, the rotor housing got deep scratches,oil leak (which you know is disaster) .. and the car had problems starting ... i think due to the overheating incident . lol

Been into the same situation,too...(Massive CNY Traffic Jam when going to Kedah in early 2012)

No such problem happened....So that was my luck,also. tongue.gif

But to add one more thing,carbonized rotary are not good.So whenever I got a chance I would rev tha b1tch hard enough especially when I was driving more than 1 hour without any redlining...I would find my way to doing it.Luckily it also handle better in corner than my fat Z33 so it kinda easy to push the engine while having a road-worthy fun with that. laugh.gif

So far no problem with my RX8 but mine was revised & facelifted version so you can expect that Mazda has made some revision on the engine,ECU & such other than just a look.(first gen ECU reportedly had a problem especially on the AT version where the engine management system didnt pumped enough engine oil during high-speed engine operation but it happened on several chassis no. if my mind served me right...In US the problem has been led for some class action suit & Mazda does make sure all the infected' model no. are getting free software update...)

Changing engine is good for reliability & power but not sure how it would effect the chassis rigidty & handling.So far I love RX8 because of the handling,& sharp steering respond.Been into track for quite a time with my Z33 & Nissan sportscar always felt heavy & less steering feedback.

I can say the RX8 had the same steering feel & handling behaviour as the NSX....Only a lil' bit sharper',probably that just me,but smoothness of wankel engine(where the polar of momentum are not up & down,but rather spinning directly on one linear direction) are making me just a bit more confident on driving it to the edge rather than both NSX & Z33.(Which I also happened to own,as well)
Ah choy is a good wankel mechanic,go for him.Best rotard guy ever !

Regarding the RX8,I admit I was love the facelifted model in Nemesis Blue & R3 package...Look dammmn good! thumbup.gif
