Ouch, sorry to see that.

 

Go buy a motorcycle stand <-- What I used to support the tranny

 

you mean dirt bike stand?

 

i did a couple maxima's which are a little harder... i used a floor jack to raise and lower the tranny

 

I am looking very forward to this upgrade. I am on tranny number.

I wouldnt worry too much, also I dont think you powershift do you? If not dont start now. FWIW to you, my TN set-up never gave me any issues, then again I cant help but wonder how much I prematurely killed this tranny by powershifting 400ft/lbs TQ...

G352NV-I appreciate the info a lot man, will come in handy soon.

Laujik-thanks for the kind words, I will keep everybody updated on this istuation I know there are many guys who could/are potentially in my situation.

 

Pulling the 350Z's trans is really easy. I pulled mine about a year and a half ago in my 1 car garage when I had my townhouse. So I had VERY little room and it was still easy. G352NV covered pretty much everything. The only thing he left out is removing the starter and the slave cylinder, which is also very easy. One other thing. Either drain the fluid out of the trans before you drop it or make sure you don't tip it too far backward when you're pulling it out of the car or you'll have gear lube all over your garage floor. Since you have the Greddy kit and I'm not sure if you have the wastegate relocators, I think you have to remove the wastegates to get to the trans bolts which could be harder than pulling the trans itself.

 

Man forgot the slave, two 12mm bolts. Didnt forget the starter cause when you undo the 14mm on the trans its comes right out.

 

Touche

 

Good info thanks guys

 

Damn, I'm somewhat late for this one...

That **** looked harsh man. That **** was supposed to be right so I could take a ride when I get back to the east in November. Dick. At least she went down swinging (again). You just can't keep a car together, can you? Go back to driving the Probe. BTW, did you put those license plates on?

Anyways, get her back up with that gear set so you can break something else... eventually you'll get to the point where there's nothing to break anymore.

Got nuthin' but love for man!

Damn Berto i cannot belive the vid.... sorry to hear bro just saw the thread ouch.....

 

taking it out was easy, i couldnt get mine back in to save my life.

 

wow.. that sounded pretty violent...

I get the impression that what you need is a dogbox transmission or something with upgraded synchros and straightcut gears if you plan on shifting the car like that...Helical gears and stock synchros are not really designed for the kind of shifting that you engage in, and by shifting so fast and shock-loading the transmission, well... i think we see the results.... But i think you might already know that...

Good luck with the rebuild, but you might want to rethink your technique a bit. It obviously doesn't bode well for longevity at elevated power and traction levels where wheelspin (which releases extra stress) might be harder to come by...

 

I don't power shift, but I shift with the clutch extremely fast and have experienced grinding from the 1-2 shift occaisonally. somtimes the 2-3 shift has problems but it's mostly the 1-2 shift. So, hopefully this spring there won't be any issues. I might follow the advice of the other 350z drivers i've seen at the track. Leave somewhat easy and avoid stress on the drivetrain and go for trap speed. The trap speed would give an indication of what I would run under ideal launching techniques.

 

Yeah but knowing what you "could" based off trap speed is silly, its what you actually run that mattters-nothing I hate more than "I run 12.3 @ 121, I could run this but I dont have traction". A quick lift shift is just as good as a powerhsift-well almost imo, so just stick to that. As far as 1-2 grinding could it be your timing?

 

yes, you have a good point there. I always hate hearing from the 550+ hp mustangs that they run 13's because they can't get traction. IMO that is the mistake of the driver and set up of the car. However, given my limited money to spend on replacing components (paying tuition sucks). I will take it easy on my car when launching and shifting and face the consequences of saying (with time slips to back me up) "I only run 12.90 at 109 mph" and refrain from saying that my friend who runs at 109 mph is running 12.23 so I should do the same. Perhaps one day I will invest in a performance clutch, racing transmission, driveshaft, and differential and be able to slip the clutch at 5000 rpm with dragslicks and see the true potential of the car.

 

You can run DR's or slicks on stock axles man-its all in how you do it. Ive broken a lot of $hit but have yet to have axle problems, MANY 6000+rpm' NA launches, many 400whp TN launches and 1 525whp launch no worries. You could launch well and shift "spirited" and still run very respectable times, faster than you think...

 

Well you have two choices;

Get some decent times and still know at the end of the day, your car should be fine...or go ***** to the walls, rape ape shifting and leave no survivors, and possibly put your cars ***** all over the track =D!!

Side note: Going to be installing new rb25det tranny on my s14 today or tommorow since I think i scatter ****ed my tranny again last night. Atleast this one will hold for whatever i need it for. New clutch felt so good, but transmissions just hate me. Guaranteed when i get my Z, it'll be the first thing to go.

EDIT: Or just dump loads of cash into your car so its bullet proof.

 

I think my problem is that in my drag radials (nitto 555 somethingorother) 245 / 45 / 17 I was running 26 psi of air. A friend told me to drop to around 20 or so and I"ll get traction.
