RX8/rotory engines

Has anyone have/had the mazda RX8 before or this type of engine tbh this is my first time actually hearing of engine like this in a car( ive heard of em but really didnt know what they put them in) i love the look and the reviews look pretty good of the rx8's but wanted to see if anyone on here had any background in these. do they need alot of maintenance? are they reliable? and for anyone who has had/or does have the rx8's how do you like it? thanks

I had the RX7 (Better than the RX8 IMO)
Rotary needs TLC. Change oil frequent. Say every 3,000kms. And use Dino Juice. Non-synthetic oil. And keep the cooling system in a healthy state. Insure all oil hoses are good. They tend to go hard from the heat and burst and dump oil at an alarming rate. I know had this on the freeway. Rotor blades knackered rebuild engine. Still would buy another. Respond pretty good to mods.

As time goes on Mazda manages to make the rotary engine alot more reliable and better.

The rotary engine kinda drives like a bike motor... power is delivered higher up and it LOVES to be revved.

The rotary also responds so well to turbos because it puts out ALOT of exhaust which makes spinning the turbo up so good.

Excellent car, excellent motor

I agree, and I am sure the current rotaries in the RX8 are alot better. Turbos and free flowing exhaust systems is the way to go.

I think Luckz88 has/had an RX8 so you might ask him about issues with that particular car. I've had a few RX-7's over the years and love them, they are a blast to drive but like others have stated oil changes and avoiding overheating are paramount to their longevity. The turbo versions are worse in terms of reliability due to the extra heat the turbo keeps in the engine and I know of more than a few that died before hitting 80K, someone I know personally is on his 2rd engine in a 3rd gen with only 120K

Talk to chad(luckz88) he had and by the way rotarys suck. They are cool motors but not very reliable.

Yeah I had one...I just sold it....it needs more power to be honest with you...A stock one is fun but it def. needs about a 100 more hp...it handles awesome and is fast from 0-120...after that its slow...i topped mine out a t157 the one night...it doesn't have any power unti you are around 5 or 6 g's to the red limiter...its a gas guzzler btw...my roomate has an S2000 and his car is faster...we dragged several times and the Rx8 wont' touch it...stock brakes and suspension are good...the bose stereo sounds awesome in it..i had the grand touring edition btw...i sold it with 24,000 miles and the clutch was going on it from driving in the mountains...its a great drifting car though but the stock tires are fuggin expensive to replace...i bought the netto b555's and they are great tires
