The shifter uses two of the factory mounting point. This puts the shifter .5" forward for FC and .5" back for FB. After I made my block off plate/brace I had to extend the shift rod out the back of the trans tail housing, this is the hole that's hard to seal. I tried to make the rod using pipe as a collar but nothing fit so i had to have it made from a solid piece. The hole is where it exits the rod exits the trans to connect to the shifter. I have a piece bolted to it like a shift boot for the rod. It's no great but should work. Once I know everything works ill invest more money/time into a better design. For now I'm very happy with what I've done.

I would really like to see more of what you're talking about here. Can you get some more pics?

Does it look at all like you could swap tail shaft housings? Then maybe use the shifter tower for the 8 on the tail housing of the 7 (for the reverse lockout)?

Nope, not at all. Two different transmission suppliers and the size differences of the case and differences in shifting mechanisms prevent it.

The tail housing also has the stop pin for the shift rod.
All I did was extend the shift rod 8cm and make block off plate/brace.

I've been busy but will keep everyone posted.

i guess i can stop telling people on the street i got the only 6 speed rx8 transmission'd rx7... in the usa... now i have to say alabama...

put some miles on my now... still no speedo :P

ghost1000

iTrader: (1)

mounts look good how do you like it over the 5 speed?
turbo or n/a and is that car originally auto?

This is 2nd gear in my car, it was originally auto trans and after installing 17" rims the speedo is only 3mph off at 75mph.
the gearing is killing this car its a holley carbed s4 6 port with 95psi per face. 1st 43mph 2nd 84ish 3rd 120something. still licks 14's @94 mph yeah its a beater 75mph 1/8mile if I had the stock tires for it I'm sure it would be half a second faster. It spends a lot of time out of the power band when I launch and shift. After this its turbo time and then EFI. I already have everything I need but time.


Just plasti dipped my rx8 gt came out real nice
Konig staggard rims
tein coil overs
ls2 coils
slotted brakes
4.1 rear gears no more granny gear its a street car not a race car.

the car is currently the stock s5 motor, building up a semi peri for it to be put in later this summer.

when i used to drive a 5 speed 7,going WOT to redline in 1st and 2nd, i would shift 1st 2nd then 5th.
now with a 6 speed i usually shift 1st 2st 6th, but if i get on the interstate i use 3rd to get to 80 before going to 6th

the 3rd in the rx8 is a tad higher then the 2nd in the fc.

you're basically replacing 1-3 in the fc with 1-4 of the rx8. 4 and 5th are both 1:1.

AngryPerson

Definitely not.... I've been rolling mine around for 3 years now And pushing 400rwhp through it.....

My question for you though is, keeping the stock RX8 tailshaft, how did you go about moving the shifter back the 3-3.5"?

Cheers

I should of taken more pics. I took the tail shaft off and had a shift rod extension made. I drilled a hole in the back of the housing where the shaft exits. I made a boot to keep oil in and dirt out, honestly this was the hard part and I'm not 100% happy with the boot but I do have plans to improve the next one I build.

The brace is 1/8" steel plate and I will know this weekend if there are any clearance issues. I used the back factory shifter holes for the front of the shifter this moves 8cm or 3.149" any further back and you will hit the drive shaft. There isn't much room to box it in so I left the bottom of the shifter exposed. If it needs to be cleaned or greased I can easily do this from inside the car.

thats the funny thing with mine, i could pull my trans and put it back into an rx8 if i wanted.. the way i did it was i remade my engine mounts, and trans mounts, so move the engine back 3 inch and down 2 inch, lower polar moment of inertia, the stick sits about 1 inch forward of the stock location, but it clears the radio because of the short throw.. also i have richard pauls short shifter(axial flow).

also mine is in a vert, so it already has a lower center of gravity, i can wait to track it.. it gets me a lot of eyeballs from the popo for taking corners/turn so fast..

I certainly agree with the more picture thing. Sholda, wouda, couda...

This explanation does shed more light though. Thank you

Ahh the beauty of having a gutted race car, I'm just going to make the stock hole more egg shapped.

lastphaseofthis

iTrader: (8)

who has the gutted race car? i'm just missing the shifter surround. doesnt quite count as gutted. also i said something about taking it to the track, more often then not it just goes to the beach...

Trans is in and drive shaft did not need to be cut. The factory Tll shaft fit. The shifter is in a perfect position and no other mods needed. I'll post some pics when I have time.

AngryPerson

Interesting. How did they build the shift rod extension and did they keep the 3 grooves that work with the detent ball and spring to keep the tranny in gear?

I'm wondering if the increase in height is going to have a negative impact on the extension and retraction of the shift rod and there's also the movement between the shift rods, moving from side to side has an impact on the rotation and overall angle. I'm hoping there is more movement allowed in the shifter to allow for the extra height worked in there with the 1/8" plate.

Really? Wtf are you running for an engine? It's definitely not the single turbo 13B-RE that I've got. There I no way possible to move that engine back at all. From memory I don't think you'd be able to get the n/a engine back quite the 3-3.5"... I guess an MSP would fit just fine.

That's a lot of material to cut away. I don't think you'd be able to use the stock dash, but maybe?

Awesome! Especially about the driveshaft, that make me happy because the custom AL one that I had made a few years ago was too short and vibrated a little because of incomplete engagement with the output shaft and bushing.

I'm going to try basically what you did, but without a plate on top, going to rebuild the shifter box where I want it but keeping the shiftrod bushing in the tailshaft right before the box, and I'll extend the stock shiftrod somehow to keep the grooves and the detent ball in the tailshaft housing

How did you solve the slave cylinder issue?

i'm running the stock s5 n/a engine? as stated. glad you've basicly called bs on what i've already documented if you simply follow the link in my sig.. you can actually see my mounts and the progress of making them. they look like ****. you can also see were i couldn't get a heater hose on the heat core for the intake manifold being slammed up next to it( although it's re routed and installed now).

Me.

AngryPerson:

I don't have a stock dash anymore so I wouldn't know either

ghost1000

iTrader: (1)

I used 1/8" plate to keep within the tolerance of the shifter geometry. You have to brace it from the side so its ridged.

The slave cylinder is still a challenge. I bought a 2005 eclipse slave but the mounting taps need to be at a angle for the rx8. I will have to modify this slave to sit at the proper angle.

AngryPerson

Damn dude.... don't get your panties all in a twist because you now know you're not the first to do this swap

Is hardly calling bs.... I stepped away from the power limited n/a's like 8 years ago.... so it's a little hard to remember these things

Gotcha.... because racecar

My solution is going to involve a bandsaw and a TIG welder... accomplishing the same thing.....

I took an old n/a slave that I found, cut the ears off and rewelded them on to match the 8's bolt pattern..... has been fine for over 4 years... 40-50k miles and I have an exedy twin disc clutch....

ghost1000

iTrader: (1)

I'm going to try the 2005 eclipse slave and I'm pretty sure ill have to take it apart and re weld the taps to match the rx8

i used a kia sportage slave, although theres a referance to using a honda slave that looks even better then the kia one, the kia one is at an angle just slightly. i'm gonna try the honda one and if it's not damn close i'm going to reweld the stock one like that angry guy.

whats the issue with the slave?

the stock rx8 slave hits the 13b oil filter.
