Sup guys~! Don't trip, I've used the search button and this isn't one of those "falling apart" B|tch*** questions... I'm just curious to see if anyone has successfully power shifted with these shifters. I've tried it once, but the damn thing just ended up grinding 2nd. I know how to do this, I did it all the time to my del Sol with no problems. I thought I couldn't do this with my stock shifter, so I got the OBX and still cant do it. I installed it right and the shifter doens't spin or mess around or anything, just wont let me power shift....Well? Anyone?

PS - Just in case someone out there is wondering, "Power Shifting" is basically when you leave your foot planted on the gas pedal and tap the clutch in a bit while slamming the shifter from a lower gear to a higher one (i.e. 1st to 2nd)

PEACE!

isnt that bad for your car? and dont you wanna keep the throttle not floored, but somewhere in the middle to just feather it so u keep a steady but not ridiculously high RPM when you shift?

anyways, i have an OBX shifter and i need a new bushing...the green one that goes in before the actual shifter...anyone got one? i'll trade you for a coaster

Its not really bad for your car, just when you miss the shift like I have been. Used to do it to my Sol all day everyday, that car still ran like it was new....so it really depends on execution.

the obx short shifter should not help you do this. if you couldnt do it with your stock shifter, the obx wont help. you might need new syncros.

I meant I couldnt do it cause of the excesssively long shift throw, you all now how that is~! I believe its possible, just havent successfully done it. All I want to know is, has someone ever done it w/o grinding gears???

Do you want to buy a new transmission or something? This IS NOT good for the car and most people agree that it does nothing for acceleration. Kinda like the automatic 'shift harder' mod.

Well, I wouldnt really say it doesnt do anything for acceleration. I beat my friend's civic HB with my del Sol using this technique, and everyone knows a Sol cant beat a civic. And its not cause he was a bad driver, cause we raced like 5 times and we were almost tied (he was ahead by like a bumper). When I power shifted, I won by like a fender....so I personally experienced the edge power shifting can give you. Anyways, lets not turn the thread into another subject! From the replies I've gotten, it seems no one really has done this for the 240....

its still bad on your transmission so i wouldnt do it if it would only gain a bumper length.

not too many of us would blatently abuse their car in that way. It is much better for acceleratin if you keep yoru foot mildly on the throttle, keeping the car in the HP-range and shift correctly.

If you really know your car, you can shift withotu a clutch. Like me =P

Actually, I can shift w/o a clutch, just not while racing. Its more of knowing when your speed is inclined with the synchros or something. I can't explain it, I can feel things more than I can think about them when I drive...I hear you on the abuse part, but hey, you only live once! Besides, I've replaced my clutch before and I can get a transmission from the junkyard for like $100...

Right i follow.. but to answer your question directly.. If it is grinding then you either arent keepin the clutch in long enough/not pushin it far enough, or its yoru transmission syncros

I had the clutch deep/long enough to shift. I dunno, maybe it just takes more practice...I'll find out a couple of weeks before I get an SR~! This way, if I mess up the transmission, I'll just swap out the engine~! heheheheheh

Like all the others said, a short throw shifter isn't going to help you to power shift. I could sometimes power shift my 240 before my short shifter and I can sometimes power shift it now. From what I've noticed though the 240's don't like it, it may be due to the tight tolearances in the transmission or worn synchro's or clutch wear or whatever, but sometimes it'll grind a little going into second or miss completely. It's not just my car that I've noticed that on either, I've driven a couple of other 240's and noticed the same thing. For comparison I have a '69 Camaro with the Hurst Competition Plus shifter on a Muncie M22. If you've never seen the throw on that shifter it's about equivalent to the stock 240's plus another half or 3/4's of it, it's obscenely long, and I can power shift that thing all day long. Of course the M22 has much looser tolerances than the 240's transmission and that's why I'm leaning toward the tight tolerances in the Nissan transmission as the reason why it's hard to power shift.

THANKS JEFF~! That's all I wanted to know, at least now I know that someone HAS power shifted with the 240....I was also kinda thinking about the fact that the del Sol was FF and the 240 is FR would make a big difference in how the power shifting method should be applied. Does this make sense???? I figure, the absence of the drive shaft and the parallel layout of the transmission/axels helped the Sol in power shifting, but thats just a theory...

Hey, it's no problem man. I'm not so sure that the drivetrain layout has anything to do with power shifting though. I think the reason you could do it with the del Sol so easy is because of the Honda transmission. I had an '86 Prelude and my brother has a '93 del Sol and by far Honda makes the smoothest, easiest to shift transmissions I've ever driven. The level of refinement is way beyond what Nissan put into the 240 transmission and I think that's part of the reason why you're having a harder time power shifting the 240 over the Honda.

Makes sense, I really like the honda transmission, that's why I'm making the 240 my daily and saving for a S2000~! That'll be SwEeT~!

does the OBX short shifter just shorten the throws or does it shorten the actual stalk as well?

it shortens the stalk a little bit, just cause the ball is set a bit higher than the stock one
