^^^ i though the right port.. combined with hella short runners and and huge exhaust housing on the turbo should take care of high rpms... <-- of course supporting mods.

Im not no tuner or anything but thats what i figured from my small amount of knoledge.

 

The redline has nothing to do with how much or how well the engine can breath. It's the point beyond which parts start to suffer unnacceptable wear or risk failing catastrophically. If you want to safely rev higher than that, you need to replace and/or modify certain parts to handle the extra stress. If you don't do that, your redline is not higher no matter what you tach or EMS says.

 

im not one of those that say tachs or ems will rev you higher....
but.. only reason i said that was cause.

i seen 100's of puerto rican tear their 12a apart. Put a full bridge on that puppy. with some atkins 2mm apex seals...RB intake mani, on a holly 650 and then slap it back together. SO oviously this has no major clearance or blue printing. ANd they all make nearly 200 whp +- at around 11,000 rpms. And i have seen those cars last for a looong time. over 2 years on a few.

^^^ so i think... your theory doesnt work on puerto ricans? ahahahahaaaa

sorry. heh but it is true.

 

well since the stock S4 flywheel starts flying apart at just over 9000 rpm, I am skepticle that there are no mechanical changes.

Toss in that a 12a is considerably smaller as far as rotational weights...but regardless I would not expect any rotary engine to last at RPMs above 10k for long... no matter what your buddies in PR say they are doing.

 

fyi

looks nicccccccce*

 

It ain't theory, it's long-proven fact. I'll stick with my understanding of rotaries rather than what you think they do in PR.

 

i dont Think . I seen them build the motor man. They just do a regular *** rebuild with 2mm atkins and port that thing right. slap a fat clutch on it. and hit the road.

I just want to make it clear that in PR... people dont have money for nice parts...
And i guarantee most 12a's in PR dont have aftermarket flywheels. Matter of fact guy down the road isnt running a flywheel in his. and he is doing 10,500 rpms. ANd i know he is too poor to have had that motor BUILT properly.

I know you guys are right... and it is not reliable. But i cant help but think that their cars DO last.

 

building an engine to support revs is a given.. thanks captain obvious (icemark) ..

 

I've heard of the puerto ricans in fl with all the RX-7s, my friend used to live there and bought is GTUs off of one.

As far as i can tell i thought one of the main things is the stationary gears on S4s warp at about 7800rpm.

Anyone translate and read the caption for the roll cage on that website?

 

man... i think when my motor goes..... i might just have to swap for a 13b re...

just cause its a beefier start. they say it hold more more than the s4 and s6's and it does 8,000 rpms stock. WOOT.

 

I have personally witnessed several stock flywheels EXPLODE at well under 10,000rpm. Got any more stories?

But that's not what you said. According to your post the original poster is "running a standalone" so "he can run as high a redline he wants". This comment is completely false.

 

i dont think the 13b-re can hold more than a 13b-rew. impretty sure the rew has better clearances and other stuff i cant think of right now.

 

am i the only retard who cant get their damn computer to translate the japanese???? i go to view then encoding, and its on western european on this site, and i put that for the FEED site and its still japanese....

how much is the cluster?

 

Drop the link into Google's translator and we get:

"sale end"

It looks like it was ¥84,000 or ~US$715...

 

I'm friends with a puerto rican, lots of stuff he does I don't agree with but he sure proved to me that while maybe he doesn't make power past a certain rpm he still winds that bitch up to 10k on a daily basis and has had no problems yet. He has done absolutely nothing to the motor besides a small port job but that's it. I chalk it up to the rotary gods and what they think you should rev to, lol.


edit: he's had that motor for a couple years now.

 

What are the chances this thread can get back on topic, and we can figure out how the pins get swapped out to make the S5n/a cluster work on the S4 TII?
-a

 

Since that procedure is already covered in detail in a thread in the archives, there's no need for this one to stay on topic.

https://www.rx7club.com/2nd-gen-archive-72/gauge-cluster-swap-pins-again-s4-wires-s5-cluster-285724/

 

Yep... its not like this hasn't been covered 25 times already anyway.

 

Perhaps the cluster swap topic has been covered 25 times already...but my question is about an S5 N/A cluster into S4 TII car...and the thread started by you and referenced above by NZconv. is a tread about an S5 N/A cluster to S4 N/A car swap.

Further more, in that referenced thread, you mention that you will post the pins/wire colors for a S5 N/A to S4 TII car swap...but you never did. Since you said that the Turbo cars need some other pins moved when using an S5 N/A custer in them.

So, perhaps we could talk about this a 26th time?
-a

 

Turbo and NA pin-outs are the same except for two wires missing from the NA (no boost gauge).

Why don't you grab the S4 and S5 wiring diagrams and figure it out for yourself? It's not particularly hard, it just takes a little time. Since you want this, it should be your time instead of someone eleses.

 

I'm having the same problem...

Drop in FEED's URL and enjoy the madness that is computer-translated Japanese.

 

^ HAHAHA... "computer-translated Japanese" i like that

 

icemark said that the s5 manual was the only one with a 8k redline, what about the automatic? cause i was told my car was originally a auto, but it has been converted to a manual, and it has a 8k redline and reads to 9.

 

The auto tranny is not capable of a 8K redline
