Oh DO WE ?? That would be news to me, since I would have put it into our drift car already!! Sorry man, we were only on stock trannies

 

That's what I was told three month's ago when I talked to, I thought it was Ray, but I have also talked to Jason and one other guy. Sorry about the mistake but thanks for being so polite in correcting me. And your not the only guys I've talked to about the transmission situation that everyone is running into with high horsepower cars so didn't mean to relay bad information but thanks for the verbal abuse.:bbb:

Oh and by the way, most cars having these problems are cars running slicks,et streets and drag radials for drag cars not drift cars. For example batlgrounds car puts down 440rwhp and has had no trans problems because it's not the horsepower that kills them quickly, it's the harsh engagement of launching at a high rpm and no spinning. I don't think your drift car hooks enough to do that unless you can pull 1.5 to 1.6 60ft times, in that case you may need a transd upgrade.

 

I wouldn't suggest using the g or z trannies for drag, but just for drift might be ok. It is something we could do. We have the additional blocks to mach up the trans but as for the transmount, measuring for the drive shaft, clearances on the shifter under torque, that we would need the car for.

 

Hey man, I wasn't trying to attack you! I was just like, holy shit, do we !??! I had to call up Ray just to make sure! Maybe you talked to Jason, and I know at one point that a giken gearbox was on the agenda, but we never got aroudn to it. I'm sorry if I came off the wrong way.

I have this 6 speed just sitting here, it's brand new. I would love to put it into a 240SX, but if you want it, you can have it for pretty cheap. Maybe a nice street car KA or something. I have the driveshaft for it as well.

Regardless, I agree with you that it is the driveline shock that kills the transmissions. 90% of the time you end up snapping the output shaft ona hard launch. Derek Greaser with a fully stripped coupe and 350whp ran a 10.9 in his car witha 1.44 60' time. He stressed that you had to be as gentle as possible getting it out of the hole though, and if you listen to it, it is. He's about the best 240sx driver I've ever met, and even driving ont he street he is very smooth about it. He uses high rpms and alot of slip to get it out of the hole, and it works. He's never broken a transmission in his old drag car, for the record.

 

I was going to ask you if the amount of transmissions breaking was due to slicks. That does seem to be the case in most of the SR tranny problems I've been coming across

360+whp/tp+
Slicks
No slip clutch of choice
Hard Lauching=
Toasted Tranny:bbb:

 

Were looking more at getting down into the 1.2 60ft times with more power than what I have now which is the reason we went with the stage 4 twin plate kit from exedy. Great cluth, but very harsh even if you launch soft. With that clutch and trying to ride it as much as possible, the most passes I have been able to get out of it is 4 with an sr or ka which is the same internals and their not high milage just 60k. The reason we did this is, I can still swap back to the ka/sr with a different clutch setup and run it on the street, and also this trans will allow me to drop the clutch off the rev limiter(7500) and not have to worry about breaking. I have broken 6 of the sr's in the last 3 months-2-output shafts-2-stripped every tooth off of third gear-2-broke 5th and reverse shaft of inside the trans inside a pressed gear. Not only will the motor be built over the winter but the rest of my suspension for drifting will be done and the 5lug so I will be able to go either direction next year with aound a half days labor for setup. looking to get around 550-600rwhp on the 62-1 turbo and 400-450 on the super 60 t3-t4 with quicker spool up ime for drifting.

Also sorry about the misunderstanding , no problem.

 

How long dd it take you to cut the aluminum plate, drill holes, line it up and weld it all? I know scott and adam are both VERY interested in it, i may know two more as well!!

 

That's exactly why we did the 300z. output shaft is double the size diameter and didn't want to have to slip the clutch. Looking for a better 60ft because I know a high horsepower sr can make it up on the top end.

 

It has been an off and on project but I would say total time would take about 3 days from start to finish. On the drive shaft, you may want to think about doing the aluminum shaft. All he would have to do is section it shorter and have it balanced by a drive shaft shop. No additional cost, you would just have to supply the driveshaft.

 

All of the cars already have aluminum driveshafts in them

How thick of aluminum plate did you use ? Because you used the aluminum plate, I ASSume that you removed the cadmium plated steel backing plate that goes between the engine block and the transmission (You know the one I always forget to install before putting the flywheel and clutch on, hahaha) This way you don't have quite as much thickness as you normally would.. Is that the case?
