mykeo4's pulsar question post(s)

[ca18datsun510]

how many of us are dedicated drag racers?

come on now, dont all put your hands up at once.

in a straight line situation that is true, but when you are doing real driving, autos can cause loss of speed and response, do to the fishing for the right gear and such that they tend to do.

[float_6969]

I'm not going to argue that a manual isn't more fun to drive than and automatic. For most people, it isn't as fun to drive an automatic.

But what I'm saying is that if all you ever plan on doing in the car is to drive it every day, take it to the drag strip, and do some street racing (which I'm not going to condone, of course) then an automatic isn't a HORRIBLE transmission to have.

[progman]

Well for the stock ca there is a 5-speed manual and a 4-speed automatic. This is why I always go for the manual .. well plus manuals are more fun and allow you to do more stuff.

five gears over four can potentially mean:

better gas millagebetter accelerationhigher top speed

etc etc.

plus all the benefits to a manual.. staying in your power band better, shift locking.. pre-loading for launch without having to modify anything.. down shifting to slow down. no heat issues like an auto.

plus manuals are generally cheaper and much more simpler to work on. I always thought they were stronger than autos... but ^^^ there says differently.

I also just don't like autos because you don't feel in control.

[missionsix43]

Yes, it's true that they rob power, but how does the loss in power to the wheels compare to the speed gained in the considerable faster shifting and not having to spool the turbo back up between shifts?

You dont have to let off the gas between shifts.

Automatics have quite a bit more drivetrain loss, they are heavier, and boring.

Generally only very very fast drag cars use them (wellbelow 10s) It is still possible to shift very very fast with a manual transmission if you know what you are doing.

Hell, get a dogbox and you dont even have to use the clutch, it wont last too long driving all over the place on the street though.

If you race a stock ca18det manual with a good driver vs. an automatic stock ca18det, the auto will get raped

Look, I'm rocking a 5 speed just like the rest of you.

YES, it is possible to never have to let off of the throttle in a drag race, but it's hard on the transmission and clutch.

If you're going to go to the extent of installing a dog box, it's probably not a street able car anymore anyway, and you would probably want to install a drag racing automatic.

Yes, in a race, a stock manual car vs. a stock auto car, the manual will win given the drivers are both good.

I'm not going to disagree with any of this. All I'm saying is that automatics aren't complete garbage. And with a little work you can build something cool...

I've been told the internals of the CA auto box are the same as the Z32 one but with a crappy torque converter (standard UK spec I mean)

I've just found the changes harsh, unpleasant on the road and actually needed to concentrate harder while driving.

[nismoplsr]

I have most of the parts you would need if you are still wanting to do the swap

Clutch pedal.Throttle cable and pedal.Shifter and rails.Brake pedal (because your's is an auto).Transmission mount bracket.Right side engine mount bracket.Rear engine to transmission to rear lower mount bracket.Front dog bone bracket.all the bolts and nuts associated with these parts.

I have all the above parts. I also have a CA18DE flywheel.

I dont have extra CA18DE 5spd transmission or axlesWhat are your plans for management? I do have a complete CA18DE engine harness also.

Figure out what you are going to do about certain things, and make an offer on the parts.

[float_6969]

The reason I asked was because there is a little resistor over by the air box that often gets unhooked by people because it makes the transmission shift "harder". I guess the idea is that it feels more sporty.

And the poor driveability of the stock auto box could be associated with programming of the box's ECU.

I've never owned an S13 w/an automatic, but I've driven them (with the KA24DE) and I didn't think they were all that bad. I think they could have stood for a little work on the torque converter as you said, but not aweful IMHO.

[dash]

same ol debate you'll find on other forums. Hard to beat an auto. Those who've actually had mild upgrades to the nissan auto, for use behind a moded ca18 will tell you its faster also (on ns.com).Gotta go extreme measures for a 5spd to outgun a healthy auto.

I can recall a starion clubmember lowering his ET almost a full second by converting to automatic, no other changes. He was a good driver who sacrificed a few gearboxes to ET better than anyone else could with the same mods, pick any turbo.

One big advantage not mentioned here is the auto's ability to leave with boost, huge difference as most street 5spd cars have no 2 step.Ever felt a heavy ol moded buick GN leave at 5psi ? Makes u dizzy! lol

Here's an excellent example of a street car. Only dyno lo 300s, yet runs 11.7 open diff. 1.69 60ft is a hard leave for a 3200 lb importhttp://www.redz31.com/forum/vi...rt=18

Auots may dyno lower, but they're generally quicker accelerating. Waste of time argueing this know fact.

[float_6969]

THANK YOU!

[missionsix43]

There are PLENTY of fast manual drag cars, any way you put it, the manual is going to be making more power because of less loss through the transmission.

examples...mid 9s 6 spd suprahttp://youtube.com/watch?v=eKTdm0ZG6vMlow 9s evohttp://youtube.com/watch?v=6jasVs82cGE

Yes, most of the drag cars that run times well below that are automatic, but, this is not a funny car forum.. this is a ca18det forum, I doubt anyone REGISTERED on this forum runs faster than 9s.

As for leaving with boost, are you joking? You are trying to talk about 11-12 second cars and saying that most manual cars dont have 2 step? You can get a 2 step limiter for around $200! Not a big deal.

There was NO WAY the guy that gained a second by switching to an auto knew how to drive manual

Even if it does shift milliseconds slower, you have to think about it, the car is STILL rolling, you arent losing much time by shifting a little tiny tiny bit slower.

Last but not least, who the hell wants an automatic?

[Liquid_Neon]

hey mykeo, u forgot to mention that ur talking fwd trannies.Im not 100% sure, but nissan doesnt have the strongest fwd auto boxes. ask sentra SE-R boys that one.

didnt someone (maybe you) jsut ask about that swap.. the E series to a CA? nismopulsar has all the goodies. he was about to do the swap when he jsut decided to get an SE.

nothing from the E series will work on the CA block... im pretty sure u'll have to change most everything over to the parts from an SE pulsar.

[ILOVESILVIA(S13)]

Sorry to thread jack. But since were on this topic of automatic trannies, I have an auto ca18det transmission sitting around if anyone is interested.

[Crazyracer77]

well if your at a dead stop, auto vs manual, with the auto transmission you can hold boost before lunching

[ca18datsun510]

depends on the stall of your converter. it will eventually lock, and you will be sitting there doing a brakestand.

[BLKTOPS14SR]

Do you have a spare auto ecu? I believe the number on it is 79. Thanks

[dash]

missionsix43you respond to a post but understood NOTHING typed.

So the ca18 and dsm auto transmission street car guys who have moded/experienced both, have no idea what they're talkin' about ?

yes, this is a ca forum. Do you really think most of us run 2 step ??One less item an auto transmission needs. Then you start tearing up u-joints, gboxes, clutches, axles, etc.. Who is gonna foot the flatbed bill?Autos don't 'shock' the driveline, and loads constant... unlike a 5spd

"Yes, most of the drag cars that run times well below that are automatic, but, this is not a funny car forum"...and why is that.... because they're funny cars... with automatics ?

about the starion;Did that sound like a question to you ? I'm not asking you if he did.If he can't drive a 5spd, explain how is it no other 5spd could match ANY of his times on the same turbo, same weight car ? He had lots of dragstrip seat time.A starion is a heavy car, stock 12A turbo is wheezy like our T25, yet he manages a 13.7 with 5spd. Went 12.8/12.9 with the auto transmission. You nor John Force couldn't come near a 12sec slip with a 5spd & 12A, same weight.

My neighbour/friend (2jz-5spd swapped into a rwd street corolla) went 7.0/7.1 in the 1/8th (mild boost). c4 auto transmission lowered ET to 6.7sec 1/8th. He touched nothing on the motor.... thats near 1/2 a sec on a 10sec ride.

2jz in a 240sx, th350 auto transmission, 8.6s @162mphhttp://forums.nicoclub.com/showthread.php?t=158212

4cyl ka24 240sx, Z auto transmission, 9.2 @155mphhttp://forums.nicoclub.com/showthread.php?t=157918

Do any of these look like 'funny cars' to you ?How is it that these *VERY clever AND experienced* cats, all who've gone fast with manual gboxes and now even quicker with auto transmission swaps, can't....1. drive2. figure out than manuals are quicker ? ...but YOU have. lol

[missionsix43]

I dont feel like arguing with you, if you want an auto get one.

have fun with it

You cant just go around stating that autos are better because some guys you know ran faster times with one.

Driving a manual car down a dragstrip is much more involved than basically launching an auto and then flooring it the whole way down the strip.

[ca18datsun510]

i dont care if you have auto, manual, or tampon injection, if you are running sub 10 second times, its not just launching and flooring it the whole way down the strip.

but manual is more fun.

[float_6969]

I don't think the debate has EVER stated that driving a manual ISN'T more fun. Or involved.

What myself and dash are arguing is that manual isn't ALWAYS better/faster than an auto.

AutoX/Road racing/Drifting, yes, the manual is better because you have direct control over the gear you're in.

I think that at lower ETA's, in stockish car, manuals are faster. The MAIN problem with the auto's that come in most cars is that they're designed for smoothness, durability, and ease of driving. This means different internals, programming on the TCU, and torque converter.

Auto transmissions needs "tuned" just as much the motor it's attached to does.

[ILOVESILVIA(S13)]

I'll check this weekend on that ECU for ya.

[ILOVESILVIA(S13)]

I found the AUTO ECU w/#79 on it. If your still interested let me know.

[tyrannix]

moo?

[float_6969]

No, Meow...

[BLKTOPS14SR]

I found the AUTO ECU w/#79 on it. If your still interested let me know.

How much to 47802? Thanks!

i realize that this may be opening up a new can of worms, but...what about paddle shifters? i saw the write up on here somewheres about a paddle shifted ka24, i think. now that would be fairly cool, i think anyways. besides, you'll never get any chicks driving a car with that ugly auto tansmission stick coming out of the tunnel without paddle shifters!!!

[float_6969]

Although it quite cool and would defiantly have some benefits over a straight auto, you've still got the torque loss at the torque converter to deal with. IDK how it would compare in an autoX as there isn't really all that much shifting done in an autoX, but when you DO need to shift, it could make all the difference in the world....

well, there's that and you've only got 3 and 1/2 foward gears (i don't rate overdrive!)

[float_6969]

Unless the differential was geared really short, you'd never used 3rd regardless. Most manuals and automatics don't get out of 2nd in an autoX.
