Hi

Just wondering if there is a way to confirm that the engine in an RX-8 is infact a high power version and not a low-power one.

Any visual signs?
Any method of checking this?

Just wanted to know, because I am curious and clueless

- K -

 

4 port = lo-power
6 port = hi-power
correct me if im wrong somebody

 

That seemes to be just about correct (I googled the port thing).
But, can you (or me, being engine-challenged at best) actually see that "that's a 4-porter" and "that's a 6 porter" in an easy way, just by peeking into the engine-bay of a random RX-8...?

The reason I am asking, is this would be a nice thing to know if you are looking at ie. used cars, to avoid being ripped off, or if you need a new engine and want to make sure you are still HP after the engine swap.

This may be very mundane and stupid questions for people with knowledge though, I hope they'll bare with me.

 

4spd auto and 5spd manuals are 4 port
6spd auto and 6spd manuals are 6 port
as far as the engine bay...there are quite a few things that are different but, ill wait for some one else to chime in...wouldnt wanna lead you wrong

Mod Note: This answer is correct for A-Spec cars only. The poster is from Norway.

 

If you were in North America, the answer would be easy. There are valves that open and close the additional 2 ports. I don't remember what they are called at the moment. You would look for them.
The European Forum would have more experience handling this type of question.

 

thats why i wasnt too sure about it :/
be sure to specify wether yours is USDM, AUDM, or JDM

 

The intake manifolds look drastically different...there is no APV motor on a 4 port also...
