shifting my 97 240sx

[matic 240sx]

down here we call it speed shifting... when you shift thru the gears on a auto...  my car is an automatic.  i was wondering how should i do it..  i have been flooring it and going first, second, third, then i hit the over drive switch... should i let off a little, alot? or what between shifts?

[Jeff240sx]

Hey man.  I had my hands on a GTech Pro performance meter.  I didn't like the readings on it (17.56 1/4) but I figure if my friend and I both use the same thing, our numbers should both be off.  So don't mind the times, because at the track I ran a 15.7.  
Anyway.  According to the meter thing, I ran 3 tests.
First test was disconnecting the actuator (that thing that makes your car shift REALLY hard.  17.83.
Then I switched through the gears in my auto.  17.75
Then I hooked that actuator back up and shifted manually, and ran a 17.80
Then I let the car shift itself and I ran a 17.57@83mph.
Therefore, I immediatly left the actuator connected, and have never shifted my auto.

you all know that shifting it like that with an auto will burn your tranny up right??

[Jeff240sx]

Yup. &nbsp;That's why I do it. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>
You know what to do with broken things, right? :biggrin:

hahahaha, PERFORMANCE UPGRADE!

naw you shouldnt shit if yourself. &nbsp;its true its slower cause theres about 1.5-2.0 sec from when you move the lever to when the car actually shifts (pretty dumb huh) but thats the way it is. &nbsp;so with an auto just put it in drive and floor it. &nbsp;so the car actually shifts faster on its own. &nbsp;oh yea and its true. &nbsp;eventually you trans. will break. &nbsp;but hey bet it would be nice to trade that in for a 6 speed?

[Jeff240sx]

Of course it's faster. &nbsp;By about 3 tenths of a second according to that mis-information-giving-hunk-of-sh!t GTech thing.

I need to know if the previous owner of my car took the actuator off, where is this located? My car shifts hard, but hardest from 1st to 2nd.

And when doing the quarter mile, remember to brake stand. I'm working on my launches, I press the brake while the car in on Drive, press the gas to about 2500rpm (any higher and the wheels start spinnin, I need a tourque converter), and just run. No official 1/4 time, but workin on it.

[Jeff240sx]

I'm not very good at getting pictures up when I say I will... so I won't promise.
But... on my '96 and all s13's, the actuator is located on the inside of the hood. Right side when looking at it from the front. By the battery. It is on a body panel rail.
It should be the only thing there, with a couple wires going to it, and a couple comming from it. Mine is grey plastic, and i think s13's are a bronzish metal.

Edit: &nbsp;Just in front of the strut tower (that big hump in the engine bay.)

dude, its true, i shifted thru my gears racing an integra rs with an intake... LOST, did it again letting the car shift... WON!! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'> &nbsp;heh

no more of that... &nbsp;&gt;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> and i think after i get my engine into 14s or 13s... ima get a 300zxt engine

From a roll try a neutral drop. &nbsp;All my friends with auto's do it... put it in neutral, rev it up, and throw it into 1st or 2nd depending on your speed. &nbsp; Hard on tranny's though. &nbsp;From a launch just power brake it and go.

Dont do a 300ZX TT motor... it will throw off the balance of your car since the 300ZX block is iron, it's a very heavy engine (I know cause I've pulled several). &nbsp;It will also kill your handiling... you'll go fast right into a curb. &nbsp;Go SR and mate your auto trans up to it instead.

never do a neutral drop. &nbsp;That's the absolute worst thing you could do to your transmission other than taking a sledgehammer to it. &nbsp;

[97 S14]

I said it was hard on tranny's... racing usually is. &nbsp;its up to whoever is driving. &nbsp;I know people that power shift, I'd never do it though.

if you want to race, then get a manual.

I never race against automatics for the simple fact that automatic drivers are usually less experienced and are more likely to crash. &nbsp;besides, automatics aren't competition to a driver who can drive manual well.

hahaha... go over to supraforums.com and try posting that up. &nbsp;Also go to www.syty.net and try the same thing. &nbsp;Hey I drive a 5 speed too... but don't rule out auto's... they do have their advantages.

well, of course there are fast automatics out there, but why drive one if you don't to? &nbsp;if you want a sports car (or a sports truck in the case of the sy and ty) then why even look for an automatic?

my neighbor has a dodge duster that runs 9s. &nbsp;Its an auto, but whats the point?!!? &nbsp;Its like being on a roller coaster. &nbsp;You can't control a thing.

Before I bought my car, I had a list of cars that I was considering, including the lexus gs300/400. &nbsp;When I determined that lexus didn't make it with a stick, I crossed it off my list.

All I'm saying is that automatic drivers are scary to race against. &nbsp;I'm more worried about them doing something stupid, than getting a ticket or myself crashing. &nbsp;

[matic 240sx]

it doesn't matter to me if its an auto or a stick. &nbsp;an auto is an advantage in racing if you have other thangs to worry about than shifting, like spraying nos... &nbsp;anyway ive been racing car for 4 years now and gone thru 4 different cars this one being my first auto and i like it.

and also i never said i wanted a 300zx TT engine, i want the vg30t, &nbsp;single turbo out the 85 z....

All Sy's and Ty's came auto.

[vancouvers14]

that's cause they all used the camaro/vette 5.7L i think, and those aren't available in stick either. &nbsp;too bad. &nbsp;those things haul.

Nope... they are 4.3L V6 motor's... basically the 5.7L V8 motor's with the 2 rear cylinders chopped off and a turbo added. &nbsp;Study up on your cars... the 5.7L LT1, LT4, LT5 (DOHC 5.7L motor), LS1, LS6 found in Corvettes, Z28's, and TransAM's were/are all availible in a 6 speed or auto. &nbsp;Some of the motor's (LS6, and LT5) were only availible as a 6 speed.

you can't get a camaro 5.7L with a manual. &nbsp;all the manual camaros are 5L. &nbsp;even the high performance 1LE model came with the 5L cause of the transmission. &nbsp; I'm talking about the camaros from the early 90s, not the new ones. &nbsp;The six speed didnt even exist then.
