2002 rx7 spirit r
 

can someone tell me a site to check up on engine specs

13B-REW. Same as all the other 3rd Gens.

2002 SR had 3 trim levels.... type A had 280bhp with a 5sp, type B was the same ,but was a 2+2 config., and lastly type C with a 4 speed auto and 255 BHP. stolen from my Mazda Bible. 1000 SR where produced from April 02 with end run 4 months later. So mahjik is wrong. Try reseaching next time MR. MOD! I fiqured you knew better?! I dont know of a site to help, so this is the best I can do, hope it helps. :bigthumb:

Sorry, you are wrong.

The quote "engine specs" are the same as the engine is the same. The 13B-REW engine is the SAME through all the years. What is differernt are the components "around" the engine (and the boost level was increased to achieve the 280bhp).

Now I think we are both right. It was a rather vague question, and so was the resonse. As for my facts posted, I do belive I am right. My source is Mazda's Rotary Engine Sports car, written by Brian Long. According to the book I have taken the care to reread, it wasn't just boost pressure that was changed. So am I wrong for assuming he wanted a little more besides a short blanket statement.I try to bring facts and knowlege when I post, so again, where am I wrong?

last time i checked, there were 1500 spirit r rx7s produced

edit: and im pretty sure the 13brew wasnt changed either

If you take a 13B-REW out of a Spirit R and put it in a regular old '93, it's going to make 255HP. The "engine", which what he asked, (i.e. rotors, housing, etc) is the same. The difference is the "components" (i.e. turbos, ECU, boost level, rats nest, etc).

You could take a '93 "engine" and slap the Spirit R components on it and get the 280bhp.

Mahjik: I think he was pointing out the end result difference in the models, nowhere did I read him saying that the engine itself was different, just the power output and options.

Despite the initial question saying "Engine", I assumed he meant overall power difference, even though its from turbo's/components and not the core itself...

Which is my point of clarification for the "correct" terms. Is there a performance difference? Yes. Is the engine different? No. Are the components different? Yes. Can you just buy all the updated components and be set? No necessarily.

What you assume is not what everyone assumes. Saying the engine is different/upgraded is just flat wrong.

And he didn't say that.

He said "x, y and z were different", in response to a question about the Spirit R, not directly to the engine difference..?

Oh well, I love you.

Oh really?

He is thinking the "engine" is different, as he was responding to my first comment.

When you rebuild an engine, are your turbos rebuild? Nope. When you buy an engine from Mazda, does it come with an ECU and/or wiring harness? Nope. The things that are different, are NOT the engine.

The original question, what are the engine specs; the answer is "the same as the 93-95 engine specs". Next question would end up; "then what makes them have more power" and then the answer would be what I listed as a few of the changed components.

Now, if the newer engines had different port sizes, apex seals, or something; then they would be "different".

lol wow, I dunno how I missed that, I'm a bit tired and out of it...see my "FD just sold today" thread (https://www.rx7club.com/3rd-generation-specific-1993-2002-16/fd-officially-sold-470479/) ...it's put me in an off mood...again, I love you :P

I understand the 280hp version had redesigned oil metering nozzles to improve apex seal lubrication under hard acceleration. Probably a little 2 cycle oil could compensate for this.

I wasn't trying to start anything here, just trying to be helpful.BTW I got the 1000 SR # from the book I listed, that is my only source for the SR info, so who knows, I was just relaying what I read, it might be wrong, but either way I tried.

The info is not wrong. The terminolgy is wrong. The later RX-7s did produce more horsepower, but that had nothing to do with the engine. It had to do with the components around the engine such as the upgraded Y-pipe, changed ECU, higher stock boost (and the fact that their version never used a pre-cat).

Yes, there have been lots of small changes. Typically with the small changes, the parts just supersede the older part numbers (i.e. newer part using the same part number like the apex seal change that happened about a year or so ago).

let me help you out mahjik. haha... click the link , Shelby

Here is a "Proper" web site dedicated to the Spirit-R.

All in English & very detailed.

Your point being? There is nothing in that link that says anything in the engine is different from the 93-95 version.

why are you getting on Mahjik's case? he's right, the first thread said nothing of engine changes. I for one was getting interested in the revamped air passages on the Spirit R, does anybody know if those changes dropped underhood temps?

Ahh...i see . Mm..so you don't consider a better design turbo for the 99 spec to be an engine spec change. More a component upgrade. What about the improved apex seal lubrication they said the 99 spec had ?

the engine core is the same.

this arguement is silly.

That's a simple nozzle change. It's a component around the engine (if you've ever worked on the oil system of the FD). It does change the amount of lubrication, but that doesn't really have an effect on engine performance.

Think about it this way: If you have a stock FD and you add a Pettit ECU and turn the boost up to 12 PSI. The output is now say 280bhp, have the engine specs changed?

That's basically the main difference of the later FD's as they turned the boost up and a newer ECU. The turbos themselves don't really flow any better/worse than the stock earlier turbos (which is why they aren't really an "upgrade" for us USA guys).
