Are you telling me that the 6-speed, meant for the QR25, fits on an SR motor?

Did you have to do any fab work? Pics?

I'd seriously like to know, as I have almost saved up enough for an SR20DET swap into my Classic, and it'd be nice to know that I have an alternative in trannies...

According to Travis, it's not a direct bolt on but it's very close. I think he said you could bolt it up with very very little modification

Hes incorrect...The 6 speed was AT LEAST 1.5 inches bigger than the sr20 bolt pattern all the way around...You could use a Primera 6 speed bellhousing that supposedly bolts up to the spec v 6 speed...carnut, if you dont already have a B15 or 6 speed, it will cost upward of $3k probably

Any word about the ratios? I mean, just because it's 6-speed, it's instantly better...

My stock gears are close enough as it is, and I wonder how it'll feel with an even closer ratio. Pimpride?

Also, I'm shooting for a streetable 400hp, maybe, and I've heard my tranny will eventually need replacing around that point. Since after market is so expensive (not that a tranny from a newer car will be cheap), I am wondering also, how strong the QR trannies are...never really bothered researching them.

this is the only picture that I have fo the adapter plate

the sr20 trans will need to be strenghtened way before 400whp IMO...ppl have had 3rd gear failure N/A...The 6 speed is supporting 400whp in a Spec v with no modification except clutch/fw...the gearing is pretty close but its not too bad...i top out 4th at ~110

Crap. That changes everything, lol. That 3K is going to cost almost more than everything I'll be spending on the DET, along with install, and peripherals. I guess I'll just have to stick with my stocker, and see how far it'll take me. http://www.automotiveforums.com/vbulletin/images/smilies/uhoh.gif

Not a clue on the ratios, and supposedly the QR trannies are very strong, except for the 3rd gear synchro problem that most of the 02s had

By very little modification I think he meant just a simple adaptor plate

I'm not sure, you'd have to ask him

i have never had any trans prob. and my trans came from a Spec V w/ a 12/01 build date...It now has close to 40k miles on it

believe me, the adapter plate was not that simple

Oops, this is what I meant to say:

I think I found another pic...lemme try

I'm just the messenger, I've never tried it or seen it tried in person ;)

here, I found the original thread if you're interested:
http://www.b15sentra.net/forums/showthread.php?s=&threadid=59670

Thats not an adapter plate...Thats a new BH...I was going to do that but JWT said they were having some problems making it reliable

ah, well I stand corrected

I was thinking it was an adaptor plate, but the last time I read that thread was almost a year ago, I guess my memory isn't quite what it used to be ;)

its cool

anyways, I think that with that trap speed, I will be able to hit 12s if my clutch doesnt slip

pimpride......You're giving me evil ideas. hmm... I may have to re-think my swap.

Sorry to bring up such an old post, but you're seriously overestimating the strength of the SR20 tranny. That thing's going to go out on you at around 250hp. Your stock tranny probably wouldn't make it through one race if you were pushing 400hp through it. Better look in to PAR gearstacks.

you just repeated the same thing I said earlier

I gathered that already. Do you have any more info on these PAR gears? Never heard of them. I've already thought about shotpeening or cryo-treating my gears in the future, but if a fair-priced replacement is available, then I might go with that.

when you say the tranny will fail does that mean he needs to get a stronger cluth or what

PAR gearstacks are nowhere close to cheap

tranny != clutch

Cryo and shot-peening will give you about an extra 50hp capacity, so don't plan on anything above high 200's. The PAR gearstacks are good for about 650hp but they'll cost you somewhere around 3 grand. Good luck with 400+hp, that's a little too unreasonable for me.

The PAR gearstacks are good for about 650hp but they'll cost you somewhere around 3 grand.

So about as much as the stock QR25 six-speed, and apparently much stronger. I never asked for cheap, because I know that'll never happen. All I wanted was fair-priced, and that sounds fair-priced to me. http://www.automotiveforums.com/vbulletin/images/smilies/smile.gif

As for the 400HP goal, that would be crank, so about 320-340WHP, which is not unreasonable at all. My starting point is a GTi-R DET, which can more than handle that much HP, and more. Who knows? I might exceed that. That's also in the course of due time, not all at once.

yeah, but remember, the tranny can handle your max crank HP. Not your whp. 400hp is too unreasonable for me because of all the extra cost with tires and premium gas. You'll be eating a lot of gas even when driving normally. You'll also need to get a hardcore clutch. Probably even harsher than mine. It would just be too uncomfortable to drive for me unless it was exclusive to the track.

what mods you got on that thing

on what thing?

on my car? see here- www.cardomain.com/id/sr20det6spd

Alright pimpride, I am from Oz and just wondering how did you get the RNN14 SR20DET(the GTi-R motor) to bolt up. I owned a GTi-R here in Oz that got hit by a truck and I have had no luck fitting the motor up to my FWD SR20 car. The gearbox/engine dowel holes did not line up and there were four bolts that did not line up. Maybe you fitted the GTi-R equipment to the factory block?? or what?

i cant really understand what you are saying :confused:
