If your installing the PPG, why wouldn't you just use the RX7 case?

Dear God...have ya read ANYTHING on this thread Ernie? lol

- No one wants to deal w/ an altered shift pattern
- The strength of the FD case is simply inadequate for higher power levels
- The Getrag is simply a superior tranny in every aspect
- Plus it's a 6 gear setup

For these reasons:
The real nice thing about it being a 6-speed is that it will have a 1.0 5th just like your 5-speed conversion but I will also have a nice overdrive gear. The absence of that was one of the big hang-ups for me with the 5-speed conversions. My car, as much of an excersize in stupidity as it will be, is still a street car. Highway driving with a short gears sucks imho. Been there, done that.

Also, it is FAR easier to relocate the shifter anywhere you want on the Getrag. I have a 20b that has been moved back and will inevitably have to deal with that issue.

Fwiw, I could care less about the shift pattern.

OMG I can't believe I forgot about the MOST important point! That tripod shifter is an *amazing* thing is it not?

Strength of the FD case? I have about 20+ passes on my tranny with no failure and nobody around is making the power or torque I am. Till somebody breaks a case with the PPG in it, I don't see it happening. The getrag is great, but you can't race in NHRA or Nopi with it. Just seems like a waste, unless your using the Supra tranny as it sits.

damn guys you know how much better the gas milage would be at cruising
with those rpms, and you could drive faster too. The best gas milage I found is at 3100 because thats right below where the secondaries kick in i guess. If you leave the rpms right below 3200 then you only have 2 injectors going. Is there any way to fit any thing lower then a 3.90 rear in the pumpkin with out going to a cobra rear?

Ernie, c'mon now. You're not listening. It doesn't matter if you put a MOUNTAIN inside of the tranny. It's NOT the internals we're worried about. It's the CASE. The EXTERNAL, on the oustide, NOT the inside, exterior case lol. I musta repeated this like 5 times for ya already on this thread alone, not to mention on other threads. So what gearset you put INSIDE the case makes absolutely NO difference on whether the case will flex or not - unless the gears lose sooo much energy in the transfer that much less energy is transferred to the case - at which point the gearset would be horrible in it of itself lol.

You say that you're the only one running the PPG, and it hasn't broke etc etc. That's all fine and dandy. But will all respect, it's simply not smart (that's the nicest understatement I could come up w/) to come to widespread generalizations and conclusions from a single SOLE experience - your own. You just said it yourself. No one here is running that kind of power. So there is a complete LACK of evidence to support your claim that the case won't flex. None whatsoever in fact.

On the flipside, however, I've already addressed the point of the AMPLE proof that the case DOES INDEED flex in my previous post: https://www.rx7club.com/showpost.php...2&postcount=50. And if that wasn't enough, crispeed (who isn't exactly a newbie lol) supported my assertion. Here it is *again* in case you missed it the first time:That explains the problem SO well, no further words are necessary. Really.

The only question is, are you calling BS on what I, crispeed, and the Aussies have seen and attested to for YEARS? And based only on your self-admitted SOLE experience, which is premature at best? C'mon now... You know me. I got nothing against you. In fact I think you're a real cool cat. But I think you're being a wee bit too confident and defensive of the route you took, simply b/c you took it - and not b/c of the evidence that's been presented to go against that route.

Which is why I'm doing my best to do w/o the PPG gearset

Ernie, I'm not questioning your trannie or your decision to use it and believe you made a good decision in the time that you did.
I could care less about drag racing. I run road courses in a super unlimited (i.e. run wut u brung) time trial class so it works with what I'm doing.
You're kidding, right?
Synchros and I do not get along on the road course and they also just happen to be the sore spot with the Getrag apparently. I have plenty of experience with straight cut gears on the track and for me, given the choice, there is no choice, especially when there is an overdrive gear available.

Cool, hope everything works out. Only reason I asked about you getting the PPG is the stock Supra tranny will hold over 1000rwhp.

Random question -

Ramy, why dont you make hardened Cases. You can make anything.

FDNewbie

iTrader: (10)

LOL. I considered it. But it's prob more work than is worthwhile, given Carlos' full Getrag bolt-up kit. A hardened case will be heavy, and it'll be expensive. The only way to offset the cost would be to have several sold, and I have a feeling not many ppl would be in the market for this, esp. given that a 6-speed is simply a *better* way to go IMO.

In short, re-inventing the wheel - while sometimes necessary - should never be done with other better pre-existing wheels are readily available...esp. when they're German

Cant wait for Carlos to come through on this. It sounds like he is well on his way.

FDNewbie

iTrader: (10)

mirabile, Carlos isn't still making the kit; it's already finished. He made it a while back. He's just incredibly busy ATM (just got back from a race), so I'm sure now he'll have some more time to post up some pics and include more details.

~Ramy

Just wanted to give everyone a head's up...Carlos is very sick ATM. So please be patient; he needs time to recover. Wish him well (even though he won't be able to check the forum for a week or so).

~Ramy

rarson

Any word on how he's doing?

FDNewbie

iTrader: (10)

I spoke w/ him yesterday actually. He's much better, but still has a way to go before he fully recovers.

Xeros

Hey whats the deal with the Getrag convertion? Is it gunna happen or what? My tranny just got blown south hardcore due to minor complications..twas a JDM too. Now my power levels arent huge, but I know the quality of the Getrag far surpasses, the Mazda tarnny, and from personal experience and what I have heard from others Mazda ones suck for the most part where as the german engineered and built getrag is as good as it gets and I'm just considering the swap at this point.

Xeros, as I mentioned, Carlos' health wasn't the best (he was very sick) and took a lot of time off from work. Plz be patient or look elsewhere for another solution, b/c on car or "deadline" is as important as Carlos' full recovery IMO.

'Yo peps

Spoke w/ Carlos today at great lenth.
Says he's made great progress in his recovery.
Said he's been visiting CLR and doing office & light work.
Can't lift nothing as yet.
Stated he was bored and would be going back to work in full next week.


I'm sure he'll be shiming in pretty soon.

Is this the before pic?
Before, you gernade the internals that is.

ReZ311

iTrader: (4)

Do you have proof of a RX8 transmission internals grenaded? And not from brute muscle man shifting? From what I have heard, the RX8 transmission can't handle 9000 RPM harsh shifting. 2nd gear is the weakest gear. I was informed the 2nd gear sync/crown/hub assembly flexes and causes a dented ball to pop out and then the internals just eats it up through the whole trans causing a big failure mess. Obviously drag launching is not my intention.

I want to see how this one will hold up, and if it doesn't blow up I will get another and upgrade it to handle more stress. I'm just trying to get a 6 speed going that is a simple swap for the 20B.

Xeros

My bad I must've come off alittle harsh. I saw he was sick I wasnt sure how old this thread was. So I apologize. I've got no real deadline. I hope he gets better soon much liek the rest of us.

That's gonna go up there w/ my list of fav posts hahaha.

ReZ311, just FYI, DontBeARikki blew the stock RX-8 tranny USING AN RX-8 less than a month after the car was bought. So on a 20B, you're pretty much SCREWED. Not a good idea my friend.

On a sidenote, did you have the UIM freshened up by a shop? Cuz the emblem and sticker look like they're mint...

No worries. My apologies if I came off harsh too
