Anyone know if you can use an oem r3 rear bar with the brackets and bushings that came with a progress tech bar?

I've owned 3 rotaries - 73' RX2, 79' RX7, and my current 05' RX8. My previous RX's ran great and with good maintenance, I got over 100K on each before I was forced to sell for one reason or another. Now, I just had my second engine failure on my RX8 after 40k. I've heard the Renesis is not as reliable.


My questions are:


1) Is this true regarding the reliability?
2) What is the best replacement? (My first was under warranty)
3) Where can I go to find more info? I'm trolling the forum history but a quick answer is needed.


Thanks...

This will answer 1 and 3

Lots of possible causes for failure.


2) if it was just general low compression, then your cheapest option is a rebuild from a reputable builder. If you had any other major failure, like a seal letting go or you overheated it (which can happen before the factory temperature needle starts moving), then your cheapest option would be buying a reman from Mazmart. A reman from the dealer will be similarly priced (depending on actual markup), but you are screwed if it's doa.

Change both #1 and #2 tables . If you go to the mazdaedit thread and search for Oltman . He gives a full description on what all 3 tables do in there somewhere.

Can you take the 0.767 ratio 6th gear out of an S15 or BRZ gearbox and replace the rx8s 0.843 6th gear with it? Or at least the 0.787 from the series 2?

What do you hope to accomplish?

Nathan Atkins

just lower cruising rpm, i think i might be able to get a freebie S15 6th gear pair from a friend of a friend, and they can sit on a shelf for ages until if/when i need to rebuild my transmission and i can just stick it in there while i have it apart. basically it'd just bring down my highway cruising rpm and give a little bump in economy without effecting the ratios i use on track/autox. (nobody will care that it isnt STX legal cause we stay in 2nd anyway) So if it has the same internal race size yadda yadda then it should just slip right in. just wondering if anyone has done something like that.

really id like to get like a .6 ratio but there isnt anything out there, maybe I could make one in the machine shop o_O

I'll go out on a limb and say it wouldn't help mpg much if at all. I have nothing solid to back that up. Just a hunch

Nathan Atkins

Well I had used a 4.777 final drive diff from a later model car and it took 4mpg off the car (20 down to 16 highway) and thats a gearing difference of 7.5% or so, so if i use the .767 instead of the factory .843 that a 10% reduction in engine speed, it might not be as dramatic a gain as the loss was going the other way, but it should be some improvement. My car is stock so at highway cruising speed ive got somewhere around 60-70 horsepower available in 6th and really only need about half that to maintain highway speed. lower revs would put me closer to optimum BSFC one would think. Like basically what Id like is to cruise at 75mph while placing a 75% load on the engine, I think the .767 6th gear would get me the closest to that with off the shelf parts.

I dunno, I'll try it whenever the time comes, if it can be installled i will do so, and I'll let you guys know if it helps.

Unless they really suck at driving you just don't have the powerband get where you need to go!

cuttincorners

then i will throw my mcdouble at them and gun,,

cuttincorners

so your sayin with my list of mods i cant take down a stock s2000 ..please tell me your jokin..even with matched drivers...seriously

RIWWP

iTrader: (2)

You gained MAYBE 15hp with those mods, and it is isn't remotely close to making up 300lbs of weight that the S2000 has on you.

cuttincorners

i see........ill just hook the s2000 up with my fat sister

Or you could prove how much more mature you are than either of those other drivers, and just learn to like what you have for what it is, and not feel that you have to try to prove how fast your wallet is.

There is always someone faster, and it isn't worth getting annoyed over.

cuttincorners

so what will it take for a na rx8 to take a s 2000
what am i missin thats good...and dont say fi dont want it...and hold back on tellin me how its cheaper to go fi..i like to waste my money lol

RIWWP

You are missing forced induction, a bigger engine, a lot of weight reduction.

The RX-8 isn't a straight line car, and the engine is already very nearly maxed out from the factory. If you want to add power, you have to take extreme and expensive steps to do so.

It isn't what you want to hear, but that doesn't make it not true. Until you learn to accept this, life is going to be rather painful for you with an RX-8.

cuttincorners

oh well i had an 8 for a while and love it just was wondering if i was door to door to a s2000 so i didnt open my mouth and look stupid,,,just pumpin for info..ps i love my 8 dont want a s2000 ..
only pain i got is being stuck behind a slow driver on a twisty road thanks yall.
