Like they say, if you aren't braking things then you don't have enough power

Sounds like you might have reached the limit of that trans. Either the gearset or a built auto is probably your best bet.

NO TO THE AUTO. Spend the coin on some gears, and billet forks. Maybe hunt for a R34 6 speed... then remove the T-case like people have done with the rb26 box.

What tires are you running? This thing must be hooking hard to shock load the trans like that causing the damage. Also I'm sure you could shift a bit slower. Your not flat footing are you?

Maybe a V160 from a supra ? just thinking outside the box haha it would need an adapter plate just like a built auto transmission would need.

As much as we'd all love the 6spd Getrag box, people usually charge enough to shatter hopes and dreams. The Getrag gear box is a beast though... A 5spd gearset is a lot easier to find and install when it comes down to wallet thickness.

"Sw and boost logic were able to achieve a 241 mph pass on the Texas Mile and a 7.99 quarter mile pass with the stock getrag v160 transmission."

"However in 2009 a 246 mph pass was made in the mile and a 7.91 quarter mile pass with the stock getrag v160 transmisson"

It's a really pricey transmission for sure, but it's very streetable, and most importantly reliable. I'm just throwing the idea out there you never know if someone down the line who stumbles accross this post could get some inspiration ( with deep pockets ).

Good luck and congrats on all that power that's pretty sick !

Your car + 7grand for the s15 ? If it's 7 grand USD you're crazy unless of course you got all the parts on your skyline extremely cheap Sexy s15 and sweet r33 I wish they where both sold here.

I know I know, however tho when you consider the $3500 PPG set, + labor to install your looking at over 4 grand. Not sure what he can pick up a 6 speed from the GTR over there for, but it will be easier than making a bellhousing adapter plate and possible shifter location issues with the supras V160 which internally is the same transmission. V160 is stronger than the PPG gears in a GT-ST box, supra boys make 1300+ wheel through them shifting hard, running 7.9X times and don't break them. Which I'm sure you know. Not to mention they weight 3300-3700 w/driver.

I look at it this way, even if the GTR 6 speed is ~5k knowing it wont break might be worth it....

Crazy your blowing the trans even granny shifting. Generally shock loads are what kills transmissions first. How much torque did your motor make? Boostz3 is making about that same power and as far as I know has never ruined a gear, but has broken a shifter fork.

im prety sure hes making around 100 less hp then me the z32 tranies hold up better cause of thier shorter design less shaft flex its what ive been told, the na z32 tt z32 pathfinder frontier trany gtr ecr33 are all the same gears jsut diffrent housings

I'm aware of those internally same trans. Last I thought he was making 700ish on e85 through a Borg Warner Turbo... I could be confusing cars, but I'm pretty positive on that.

Maybe on the shaft flex, the R33's is like an inch or two longer, so sure it might be possible to get a slightly larger gap as the mating gears pitch circles are pulled apart under high load. Most likely a flexture that the naked eye couldn't see..

I'm talking about the R34 GTR 6 speed getrag transmission.

Did the car make it in gear? It once the gear entered 3rd what happened? Or where you pulling through 3rd and it just blew to s*** part way through?

Hey Regan have you looked into the Pfitzner Dog boxes? I have seen numerous GT-Rs in the UK and Australia that are running 8-9 second passes with no problem

Built Auto FTW. Drag racings pointless if your not running consistent ETs.

A buddy of mine is using a PPG 5 speed GTR transmission in his 1000hp'ish R32 GTR back in Oki. He's pretty happy with it so far, except they sent him some wrong parts at first which they fixed, and now it it keeps popping out of 3rd unless he holds it in there. Not sure why. He said the price wasn't that bad since the USD was mopping the floor with the Aussie Dollar at the time. About that 15, you would be doing an RB swap I assume? Any way you slice it though, PLEASE get rid of those hideous 3 spoke rims. On what planet do ANYBODY ever think those look good?

What? First off, bracket racing is gay. Extremely gay. Like two dudes making out gay. I'll assume you aren't talking about that. Now I don't know how much drag racing you do, but trying to build my car to go faster and challenging myself to drive it as fast as possible is why I do it. Trying to drive that beast Regan drives is more than tough to do. Now if you said he should go auto because nothing shifts as fast as an automatic, I might see your point. Of course I want to beat what ever car rolls up next to me, but I'll never go auto to help do that. I completely agree with shocker. The only way an auto transmission isn't lame is if your car has single digit e.t. potential.

Isnt he breaking all his trannies through drag racing? Hes got a fast car and by his sig he hasnt gotten out of 11's yet with 600whp. Thats a problem. Its not just being able to drive the car, its having it properly setup to run fast. There is so much crap to deal with trying to run fast with a stick car that it can take the fun out of it. Just because its auto doesnt mean you cant roll race with it. You put it in a low gear and go. The only gear you dont want to race in would be your OD which shouldnt hurt if your cars gearing is properly setup. With his power, 3rd gear or his 1:1 gear should be doing well into the 140's. Thats plenty fast enough to roll race or beat anyone from a roll. Ive done alot of drag racing, street and strip and it becomes quite emabarrassing trying to tell someone how much power you make and then let them watch you run to a 11 or 12 second 1/4 cause you chunk the launch or miss a gear. You dont have that issue with an auto. OP, look into the 4l80e if your interested in having a super strong trans with OD. Otherwise pickup a Th350 or th400.

That is a weaksauce way of fixing this issue, and IMO is for lazy old timers. Its way more impressive for me to see a 10 sec ~ single digit car that is piloted through a true MT. His 700+ whp skyline is more than capable of a 9 second pass, but that comes down to the driver mod and a transmission that can handle it obviously.

With a transmission that can handle the power, and enough seat time he will see great times I'm sure. There is a good deal of 6mt Supra guys who can consistently cut 8-9 second passes with very few botched/fubared runs in between. I see no reason this cant be done with a properly pieced together S-chassis, Skyline, or Z w/o the use of an auto.
