FD RX-7 Rant

I happened to be perusing one of my new favorite websites nextautos.com and came across an article for the 93 RX-7 that claimed it may be the greatest sports car of all time. I personally agree. The pixels weren’t even dry however before the reliability card was pulled. This being a sore spot of mine I had to chime in. Read my response below…

Let me dispel those reliability fears right now.

Its true the vast majority of examples belonging to the dead 7s society do so because of blown water seals, over heating, and shattered apex seals. However I just help but to take up a Jihad every time I hear that reliability card pulled on the RX-7.

If you cant tell from my defensive position on the subject, I’m a FD RX-7 owner who has seen the end of my own 13B engine and I can tell you one thing for a certainty, all of the horror stories you’ve heard about this car are all thanks to the poor maintenance habits of their negligent owners. I admit, I’m also part of that club.

What I’ve learned from my experience as I researched to complete my first rotary rebuild, is that that engine has to be absolutely pampered. The car needs to be warmed up and allowed to cool down. Not doing so degrades the oil very quickly in turbo cars which doesn’t make it easy for the turbos and apex seals to do their jobs. Its easy to understand the turbo side of things, however most don’t know that the RX-7 injects oil into the combustion chambers to lubricate those apex seals. I am convinced that if proper and timely oil changes are carried out, the seals would be well lubricated and not generate so much internal heat which I believe is most likely why water seals, which are very close to the combustion chambers to begin with, loosen and expand to failure. That having been said, the car does benefit greatly from minor cooling modifications as well.

Staying on top of those two issues alone would keep the vast majority of RX-7 owners out of a lot of trouble. Like me its not something many pay attention to when making their purchases and completely forget about the first time they experience wide open throttle past 4000 rpm. Make sure the life blood of your rotary is changed just a little sooner than you would in any other vehicle and keep it cool. This will make for a very long lasting RX-7 that will continue to provide oodles of fun every time you turn the key.

The Dynamic Duo

I thought I would show everyone what I am personally working on.

Theise are both of my personal cars.  A 1985 Toyota Corolla GT-S and 1993 Mazda RX-7 Twin Turbo.

'85 Corolla GT-S and '93 RX-7

The ’85 Corolla GT-S The mighty '85 Toyota Corolla GT-S.

The Corolla GT-S is famed for being one of the very few sport compacts produced by Toyota as a Rear Wheel Drive.  With a close to perfect 53/47 weight balance the car was fitted with suspention and an almost bulet proof transmission and factory LSD that made this little car quite a hot number.  In tuned form it has the rare privilage of outrunning quite a few sportier models on circuit tracks even today.

The ’93 RX-7 TTThe '93 Mazda RX-7 TT

I stepped into this car after having owned a Front Wheel Drive Honda CRX Si with only 130 HP.  Making the very large leap to a Rear Wheel Drive 250 HP monster like the RX-7 was indeed a learning experiance.  With the engine mounted behind the front axle the RX-7 is rightfully considered a Mid Engine vehicle and just so happens to have a perfect 50/50 front/rear balance and gives very good feedback alowing drivers to anticipate almost everything this car is about to do.  What you may not expect is just how much of it the car is about to do.

 Right now my RX-7 sits waiting for a Dodge Diesel truck to die so it can have a single turbo transplant however the Corolla is ready for its new heart right now.  Its currently waiting for an oil pan and bearings to be picked up this week and the engine IM rebuilding for it will be finnished and dropped this month.
