hello guys, i have a lightly modded 98 240sx le 5spd, and of course, like most of you, i have gone through the 'should i get the torque monster ka-T, 'hey-my-granny-has-one-too-sr20' rb25det or hehehe, sorry, makes me giggle, rb26dett?i have now finished paying off my car for 6 months now, and can finnally afford to get my baby, rb26dett with for now the rb25 transmission. I will eventually going to go single turbo to achieve at least 700whp. No this will not be a show/drift car, it will be pretty much dailydriver/highwaymonster to hang or beat many of my blown viper, single turbo supra, twin turbo vettes etc. The problem is of course the transmission, i have heard that the rb25 will only hold so much, like in the area of 600hp, what transmission could i use to hold that much hp that wont break every two runs? could i take the rb25 transmission to a shop and have them modify it to make it stronger? get a 6spd getrag gtr 6spd transmission, of couse, it will be RWD, and NOT AWD, or maybe even a supra 6spd transmission? i want to stay away from auto trannys or american trannies, any suggestions?

http://www.quaife.co.uk/products/gearkits.htmTake a look at these gear sets if your serious, and find a good mission shop to put it all together for you. A mate of mine here in Japan used one of their dog mission sets and loved it.

thanks for the replies guys, i appreciate it, about the 6psd transmission w/the adaptor plate from mckinney, what kind of transmission is that? what kind of car is it out of, i guess if it is american, i can deal, as long as its not auto, has to be 5/6spd, thanks, ill check out the quaife gearsets too.

well, i checked out quaifeamerica.com and they have a rwd sequential transmission that will work, lol, problem is, its extreamly expensive, one is a little over 10 gs, and the one they recomend is 16gs, it is sequential, virtually bulletproof, and is used on the Chrysler Team Viper in sweden, dont know how much hp the viper has but im guessing at least 600whp, at the least, either way, sean morris is working on mating a supra 6spd transmission to the rb26 block right now, im praying that will somehow work so i can use it on my 'monstor'. I will keep you guys updated.

if you can afford to build your car (CORRECTLY) to 700rwhp, you can afford 10 g's for a good sequential transmission.

If your going to rebuild your car to handle 750hp you would have 15g in parts at least. My rb26 is getting rebuilt right now and it should be good for 900-1000hp but I'm going to run 600hp and 9k redline. 600hp is mad scary in a 240 they are so light. With 600hp you should be able to break into the 8's. What would you need 750 for. I welded in the middle of all my spotwelds so my s14 will not twist. I dont think a 240 can handle any more than 600hp or it will twist. You can have the rb25 trans cryogenicly frozen and it should be able to handle 700hp. What would you use for a rear end? You would have to dump so mutch into your 240 to get it to handle 750hp. 750hp sounds like a pipe dream to me. I will have 600hp and my car will never see the road with this amount of power. If I tuned my power fc for like 400hp I could see driving it on the road. Have you ever drove in a 240 with over 300hp I dont think so or else you would not be aiming for 750. Thats my 2 cents about that.

That's exactly how I feel.

You'll kill yourself with that much power.

Do yourself a favor. Get the engine in and running. Then think about what you want to do next.. it's ignorant to sit and daydream/worry about problems that you don't even have yet.

btw, what is a 'transmission opportunity'??

hahaha!!! newbie with 3 posts, i dont have to post senseless $hit here all day and have 5000 posts to be 'credible'. have you ever ridden in a 800whp supra? i seriously doubt it, how about a s/c viper? no im guessing, i am not looking to do any drag racing at the track, or autocrossing, this is purely a toy/highway monster. about affording a 16 or 10g transmission, lol, affording wont be the problem, im guessing you are one of these ignorant dumba$$es that goes and buys the first thing no matter how much it is before doing real reasearch and comparing other probabilities. in 6 months, i will have graduated college, and start making 75k plus a year easily, with no OT, so i really dont want to hear any of this 'cant afford' crap. I could easily just sell my 240sx and get a supra and get those numbers i want, but thats not the point, i love my 240sx, love the way it looks, feels, drives, same things you love about yours, so dont come to me trying to seem like a know it all bcs i have 3 posts, i have been reading on this site for about 5 years, through several forums, i just do research instead of asking stupid questions like ' how do i swap a sr into my 240sx?'. So if you arent going to offer a decent reply to someone's post, just dont, no one wants to hear how stupid you sound, i expected better from nissan owners. Unlike that BS post about a rb powered 240 beating that 'R1', i am trying to seriously beat a liter bike. its hillarious, sure its plenty fast, but no R1. My friend has a modded R1 and i have ridden it, lol, its nothing to play around, it takes at least a 600whp supra to hang/barely beat these bikes on the highway, with good riders. That is all, i wont expect much help from some of you guys, and id appreciate it if you just click back and keep browsing.

Yes, that's me! How'd you guess?

Actually, why did you guess?

Maybe in a few years when your balls drop, you will return to your post/s you have just made in realization of having been a complete idiot.

I honestly find it strange that you would defend yourself for so long. No one cares. People have made their point. If you don't like it, then go eat a box of ice cream.

By the way, next time in defense, try not to make it so long. It only shows us how your brain operates. It's not elaborate, it's more like a dead giveaway. In other words, it's a backfire, because it tells us exactly who you are, and how you've made considerations about YOURSELF. Insecurities are direct insight.

And, YES, I have ridden in a 800whp supra. Actually more. And the other night, I got to ride in a 1998 modded Viper. I could care less if it was supercharged. Power isn't the only thing that makes me happy.

A guy of your caliber is going to kill himself in a 'highway monster'.. I hope you've prepared your burial. We aren't stopping you.

You just gotta leave ignorant people like him alone. First off Who cares how much you make or if you graduated college? No one.

*about affording a 16 or 10g transmission, lol, affording wont be the problem, im guessing you are one of these ignorant dumba$$es that goes and buys the first thing no matter how much it is before doing real reasearch and comparing other probabilities*

If you have so much money and such a hott shot why don't you call the company that makes what you want instead of comin on here and making yourself look like a complete a$$. We are here to to learn but obviously that wasn't the case for you when you came in here acting like a hard A$$.

*have you ever ridden in a 800whp supra? i seriously doubt it, how about a s/c viper?*

800hp? S/C Viper? I doubt any of those people would let you ride in their car let alone LOOK at it. And you probably think thats fast huh? Come to Detroit and try a 10.50 Mustang, 9.50 Malibu, and a 8.70 Mustand Notch. That supra and the lil viper of yours aren't sticking anywhere close to our stuff. Ridden in? Who the hells cares about ridden in, go DRIVE a 800Hp car and I'll give you 5 seconds before you hit a f*cking tree and kill yourself. Stating all of those facts makes you look like a BullS#!TTer because youre over defending yourself.

*That is all, i wont expect much help from some of you guys, and id appreciate it if you just click back and keep browsing.*

How in God's green creation are you gonna tell the forums Guru's what to do? Youre the newbie here, so don't think you can just jump in the ring and box just because you got gloves. Go take your sorry A$$ elsewhere, go shove your money up your A$$ and while your at it go make that 800whp Supra of yours and go hit a tree. Rid us of your stupidity.-Alex

Ooh a 800hp supra, my 240 will wamp the **** out of it once it's done. Supsa's are tanks. Who cares about them. I have 2 solid years of hard work to swap/get my rb26 running in my s14. My friend use to work a John Haileys and they have a supra with 1200hp that some indian spent $200,000 on the engine and undercarage is just about solid crome. I still wouldnt trade my 240 for it. 240's with rb26 swaps are nothing compared to supras. Blackhalkgtr has little to no experiance in building fast cars. I wouldnt worry about your transmission I would be more conserned about the 26 swap. You can take the bellhousing off r34 awd transmission and put it onto a supra 6 speed transmission if you are that concerned. To reliably make anything over 600hp in a gtr engine there are so many things to worry about other than a transmission. Quit making dumb posts and get building.

You nerd. I'm not Cameron, my name is Jared. Was it really "in sells of rb motors"? lol... learn some ****ing english and grammar kid.

My post wasn't defensive either. Way to backfire on yourself.

No one is jealous of you! NO ONE! Perhaps you should give yourself a perception check. I certainly don't care what you think you'll build.

Hey, make a fool of yourself. Ruin your reputation here with your primitive retort. Think anyone is going to want to help you after you've said this stuff? Hell no.

You're the perfect example of why there should be a screening process for children. I think I'm going to email ZeroForum. How can you be so relentless with your child like responses? I guess that's a concept only a 2 year old understands.

Glad you like me. If you stick around without managing to get yourself banned, you'll probably become even more fond of me.

Actually, I'm not pissed. I find it hard to be pissed at anyone over the internet.

This is more like a practice routine for me. Trolls like yourself come and go. You're nothing special. In all honesty, 4-5 years of forum participation tends to numb you.

I'm glad you predicted I would respond! If it makes you feel any better, I also predicted you would respond to my previous post - I decided not to note that, because I don't care. But regardless, I can have your cookies in the mail by next week.

Take my advice: Remove your head from your anus and at least pretend like you want to listen to people. When you respond like a child, or use "LOL" too much, it only contributes to your diminishing self image. Do you say "LOL" to your friends when you speak to them on the phone? I didn't think so.

Have a nice day.

guys like nameless ej6 know alot about rb's and have been around the forums for a while now, Blackhawk if you didnt defend yourself the way you did this would've turned out much better.

Man I was talking to one of my friends and he was talking about a transmission that is Cryogenicly frozen and all of that.. B/c he was talking about one of them on a Maxima.. they like take them to -400*F and then like slowly bring them back to room temp over like a 3 day process.. maybe if you could get ahold of one of them, then you wouldn't have a problem. I have no clue how much you can get one for though..LoL... google it and maybe you will get lucky..

Yeah, cryo-treating has been known to work VERY well, but only up to a certain point. It still comes down to the design of the transmission and the metals used during its construction. (And the stupid @$$ Nissan synchronizers). I don't see why a stock GTS-T transmission, cryo and heat treated, and built properly by a reputable shop couldn't hold that 700 WHP reliably. Maybe that is his best option. It is DEFINITELY cheaper lol than a GetRag transmission lol....

BlackHawk: There are more options as well.

If you know the right machine shops, some of them carry exotic "tough" metals. In theory, you could give them your gears and tell them to "copy" them with their better metals. And on top of this, you could also cryo and heat treat the newer tougher gears. This in turn, would yeild you can even great HP range for the transmission. However, you still want to have the rest of the transmission components cryo and heat treated since other things can also still go wrong, other than just gears.

And on top of this, you want to make sure that you take the gears off the gear stack. Some people say that because the transmission gears are made out of different metals than the gear stack rods, during the cryo and heat treating processes the metals will expand and contract at different rates, which in turn could actually hurt the stacks and gears all together. So, just by taking the time to remove the gears from the stack will save you this heart-ache and trouble in the future. But to add to that, some people that I know have just sent the whole gear stack assembled to the cryo and heat treaters and they do the job anyways, and their transmissions still work to this day. So maybe it is a hit and miss thing, either it misses you, or it hits you lol.

Anyways, out of most of the bashing in this thread, maybe this can help you out, other than getting a HELLA expensive Getrag transmission or Supra 6-speed transmission with the adapter plate, clutch, flywheel, driveshaft, etc.....But then again, maybe having some components out of this transmission built using tougher exotic metals and cryo/heat treating will be more expensive, but you never know until you call/look around....Good luck.
