Hello all, i am considering buying an rx7
i orignally thought they were all a 1.3 rotory engine but have now found there is a 2.6 litre version. Are these versions both twin turbos? what are the diffrences between the 2 and which one is better,faster as i havent got a clue? One more question lol, is there any other versions or are these the only 2? i really need some help here so any info is good.

cheers :-)

 

There is no 2.6Liter... There is a 1.3 Liter 2 rotor... Anything else would be a swap (motor has been switched)... This is the 3rd gen forum so I am not sure but I think that all third gens that are original have the Twin Sequential Turbos... Some of the 2nd gens have turbos and some do not and none of the 1st gens have turbos to the best of my knowledge...
There are 3 rotor engines... But these are not original to the car... These generally come from the cosmo and have to be ordered from Japan or someone that ordered theirs from Japan...
If you are going to buy a 7, do your homework... They are a little higher maintenance and you dont want to buy someone elses headache... Great fun cars otherwise... I would not get rid of mine by all means... Have fun an good luck...

 

Read these, there is some good info on there.

Please use the search function, asking questions that are so easy to answer annoys the regular forum members and will usually get you nothing but resentment.

These forum is a community, and most people hate lazy people who ask such basic questions.

As for the 2.6L engine, I have no Idea what you are referring to...

There is a 2.0L engine from a car called the COSMO, but if you are looking for your first RX-7 that is a pretty costly engine conversion - $20,000.00 USD and up.

Happy Hunting.

 

ye i guess the person who told me bout the 2.6 was wrong, propably thought there was 2 1.3 motors instead of 2 654cc motors
well thats sorted one thing out lol.
i see it was made during 1992 to 2002. did they make big improvements during this time or are they all pretty much the same?

 

Improvements were made, and there were little differences were made.

The more you read, the more you'll learn.

Keep on looking, you'll find a lot of good info on here.

I browsed these forums for 3 years before I joined.

LOL

I was a total lurker.

Also, google will be a good search engine, but beware some info you read will be opinion based and usually not true.

good luck again

What are you looking for, a track car or a nice weekend warrior?

 

I believe that the "2.6L" engine is what the European market calls the standard 1.3L engine. (It's a matter of definition - there is a thread ion this, if you want further info try a search for 2.6L. As mentioned by an earlier post, there are "non-stock" 3 rotor versions of the same basic rotary engine as the 1.3L (US definition) engine in the stock production car. Per the US definition, these 3 rotor engines would therefore in effect be "1.95L" versions.

 

Some countries, especially the UK and Australia, classify the 13B rotary (which has 1.3L of static displacement) as having 2.6L of displacement because it completes each power cycle twice as quickly as a piston engine. In other words, a 1.3L rotary moves the same amount of air as a 2.6L piston engine when it's running.

One thing I've never understood about that 2.6L classification... For a single rotor, a single combustion chamber is 650-ish cc right? For two rotors, that's the 1.3L. There are a total of six combustion events per rotation of both rotors through 360 degrees. But the rotors spin at 1/3 the speed of the output shaft so there's really only 2 combustion events per rotation of the flywheel. Isn't this exactly the same number of combustion events in a 4-stroke 4 cyl engine per rotation of the crankshaft? If so, why the 2.6L classification some countries use?

 

It's Rotary Engine,...as in 'Rotate
