lol dont worry, streetz knows wat Im talking about. I gotta give it to you guys, if you can pull it off, you might just provide a MUCH cheaper alternative to VB mods. Thus, we might start seeing 5-spd track #s out of autos.

Keep up the great work

 

Oh...OK, then... Incidentally, I bought a Mobiltech VB a month ago - I was tempted to install and run it, but this Shift_Fast is proving to be very good.

Notice all the thinking going on in these threads? We're finding some really useful ideas and possible ways to make them happen.

If we can settle what people need and want to do, and discuss what things are possible, then there will be two possible products coming out of this mindstorm..

1. Manual shift_fast. Pushbutton control to shift UP or DOWN, with fuel-cut/nitrous control possible on every shift.

2. MSD-controlled Shift_Fast_2. Intended for racing - Programmed up-shifts with fuel/nitrous cuts on every shift.

Either one can switch from NORMAL to RACE by stopping, pulling the tranny shifter back into 1st gear, and flipping a switch from NORMAL to RACE. The manual version then controls the transmission absolutely from the buttons. The MSD version will start out in 1st gear and only shift up when the preset RPM is reached. The system can be reset back to first gear with a pushbutton.

To go back to NORMAL, move the tranny shift lever back to D, then switch from RACE back to NORMAL. That's it. You're back to normal operation now.

Interesting, yes?

EDIT ****** 11-30-2006 4-gang switch in a box! *****************

Well looks like I need to find another tranny, the one I was looking at wasnt vlsd. There is one from an I30 in Miami ima call about tomorrow. It has 25k miles.

 

Ask the seller for the part number. Non-VLSD units end in "A" - VLSD tranny end with "V". They mostly come in the I30t Infiniti in the USA..

Something like "RE4F04V" - it's visible from the top of the transmission.

 

Yeah I did. Well I had a feeling the first one wasnt LSD since it was from a 95 max. But it was listed under Locking and it said 10kmiles so I figured I'd ask away.
This other one is from a 98I30 I am sure it is vlsd, i'll get them to measure both sides of the axle inlet as well.
Now im wondering if I should get the vdmod and do the shiftfast.

I'm guessin ill do both and have fun.

 

If you're serious about doing it, I'll sell you my mobiltek VB for what it cost me ($150 + shipping) and help you with the 4-button shift_fast construction and installation. The fuel-cut add-on still has to be designed, but you're in Florida, right? So you'll have a chance to hit a strip or two this winter. And run the highways, too. Heh..

It's not like I have a heavy race schedule this winter... (19 degrees as we speak)

And some testing by another experienced modder should be very interesting and useful to the shift_fast/Shift_Fast projects...

If you're interested......

EDIT: I just ordered 2 each of the two different suppliers of 4-gang switches for the shift_fast version... this way I can build working models , test on my car, and be able to ship working samples.....

 

Ya, I don't need the fuel cut stuff.
Why arent you gonna use the VB?

 

I don't think I need it now..... I bought it from clee130 in Oklahoma City after he sold his '95 and wanted to restore it to original condition.. I gave him my VB from the original '99 transmission from my car.

 

Kevlo911, go ahead and get the 2800 stall. I promise you it will be just fine for daily driving!

The highest stall I achieve is 2900 and it's just fine. My gas mileage on the highway on my trip last week to and from SoFLA, I got 28mpg on one of the tanks. Around town and mixed driving, I didn't really notice a gas mileage loss of more than 1mpg. I get about 22 or 23 with a mix of highway/city.

And the higher stall won't change the way you drive around town. You will only BARELY notice that you will have to apply 3% more throttle pressure in order to accelerate at part throttle at the same rate as before.

But, I will guarantee you will have more traction issues! Which is a good thing. B/c you get to the track, get some decent tires, and see those 60 foot times drastically decrease!

My 60' decreased by .15 and my 1/4 mile times droppped 3 tenths. This is comparing stock TC with drag radials versus 2900 stall Edge TC with drag radials. Both runs were done without any chirping of the tires on the launch. This will give you an idea if you are running around a 14.0 to 15.0 1/4 mile, which is what I was doing at the time when I first got the TC.

You won't regret the 2800 stall. Trust me! If fact, you may wish you had a higher stall. But go with what Andre says. He told me that anything higher than 2800, you will start losing efficiency on the top end.

The myth with high stall torque converters is that in the V8 domestic world, a 3K stall is VERY high and not suitable for the street. It gets sloppy and your gas mileage drastically goes down! But that's not the case with out V6 Maximas that already have a stall of around 1800-2200. Raising it to 2800 isn't a big deal considering we don't make any reasonable amount of torque below 3500. It's a big difference with V8s that makes peak torque much lower in the revs.

And what you asked a couple days ago, NO, your midrange won't be effected. The torque converter will simply only give you a higher stall. That is what YOU will notice in the butt dyno. That higher stall will give you more power on the launch. But it will not effect the midrange or top end power noticably.

 

Sweet, thanks for the information. Any other info on the vb or stuff?

 

I've had the Max Tuning Stage 2 VB for many years now. It's still going great at 180K miles. My car sees redline in 1st gear almost every single day. There are a lot of two lane roads in the rural area I live. I don't have to downshift into 2nd gear, but I do it anyway b/c I CAN. I use normal ATF from Walmart and I make sure it's always in brand new condition. I have a tranny cooler too. My tranny temps never ever get above 150*F. They are usually around 100-120*F.

I don't know how a VB mod differs from unplugging the drop resistor as far as downshifts. But my downshifts did not change at all when I got the VB mod. It's still controlled by the TCU. They might have gotten quicker, but I didn't notice it. But my upshifts are instant. I think a VB mod is a must if you are concerned about tranny life.

I don't know too much about Level10. I had my mind made up after talking with NRH, to go with Rob. But I don't know if Rob still builds transmissions.

Nismology in the Miami area built up his 4th gen AT with his friend that is a tech at a Nissan Dealership. I think he got his parts from Level 10. He said everything went great during the rebuild process.

What other questions or concerns do you have?

 

Yeah I called Rob but they also want upwards of $3000 for the tranny. I might buy that mobiltec vb.

I hope I can find that vlsd tranny. It is hard to locate one, most of them listed as vlsd are not. Did you ever change anything in your tranny besides the VB and TC?

 

For what it's worth, a couple of 4-gang switch boxes are in the mail to me:

Product: SWITCHBANK-in-a-Box ! 4-GANG PUSH BUTTON SWITCH BANK. PUSH ONE IN AND YOU CANCEL THE OTHERS. All 4 Switches are DPDT-3Amp Leaf Switches by Switchcraft. Mounted in a nice new aluminum box 4.2inchW x 2.1inchH x 6inchD Terminated in a DB-25P (APP. 4.25
Unit Price: $14.95
Quantity: 2
Items Total: $29.90

The shift_fast madness continues....

 

Maybe ill buy that too, first I need to figure out a way to make a nice looking one, if not, ill get one of yours. First the tranny tho

 

I talked to Rob and since he didn't have to do anything with the torque converter, he said it would be around $2600 shipped. That included me shipping my tranny to him, him rebuilding it, and shipping it back.

No, I didn't change anything else in my transmission. Just Max Tuning VB mod and Edge Racing Converters high stall TC.

 

How about I put one together, make sure it works as advertised, and send it to you no-strings-attached? Fully wired and tested, with pictures and diagrams? Yours to use, bash, destroy, rebuild, whatever.

I'm not trying to sell any of these - ever - just get some real-world experience from an experienced modder. No strings.... It's a small price to pay to pick your brain, after all.


???

 

Sounds good. I'll let you know as soon as I get my tranny.

 

OK...........

 

One pair of the 4-gang switches just came tonight - I'm gonna build two complete packages for testing by others. One is yours.

This set did not come mounted in an aluminum box ...... If you would rather try the thing without an enclosure, these switches would work. When the boxed switches get here, I'll photograph both kinds, and you can decide...

 

Transmission is being ordered right now

99 I30 VLSD 31k miles, one year warranty shipped from Canada for under 800.

I figured I rather spend 150 more and get a transmission with low miles.

 

Outstanding! I got my I30t VLSD from Baird's in Kentucky - for about $1,000 delivered. It had 37K on it, and it still works jest fine...... These are tough transmissions.

For what it's worth, to install a complete shift_fast mod, you just need to locate the two wires in the under-hood engine harness, cut them and put on male and female crimp-on connectors (supplied) so you can restore the wiring if needed, run the supplied cable from the cabin, through the right-hand door wiring hole, forward through the fender and into the engine compartment. Plug in the attached connectors to the connectors you put on the transmission wires, start your engine, flip Normal/Race to Race, pull the shift lever to 1st gear position, and you're good to go.

 

It was mentioned a couple times but definitely get a tranny cooler if you go with a higher stall. All that extra slipping generates much more heat in city driving.

 

I got a Hayden right now, but I might get a bigger B&M one. About to order the TC. And tomorrow i'll pick up an axle from Raxle since they are in Gainesville.

 

TC ordered 2800 stall


VB and shiftfast next whenever you're ready.

 

The VB is still in the bubble-wrap, they way I received it. ?? Since you would appreciate a 4-button shift_fast in some sort of enclosure for initial trials, I'll assemble one when I get those 4-gang switches in the box. They're shipping right now. I can mount the Normal/Race switch on there, too... and probably a pair of LEDs from the tranny computer and a pair on the wires going to the transmission. I think this would be some good troubleshooting aids. I've already got heavy 4-conductor cable and connectors. What you get will be a tested device, with connectors and photo links to photobucket for the installation details. Probably take you a half hour to connect it up.

Again, I don't care what you do to it, just share what you find and think about it.

$150.00 for the VB, and I'll include everything in one box when I ship. You can mail me a check later...

 

im sorry to go a little off topic but im still confused as to what the general consensus is. The 4th gen auto tranny CAN or CAN NOT handle 191 hp?
and i dont know why i thought the 3.5's were making more power than that...
just trying to get an idea of waht to expect for when i do my 3.5 swap...

 

I'd say it can handle it. Technically we're beyond the manufacturer's torque specs, IIRC, but it's not like we're making gobs of power. Always good to play it safe, though (tranny cooler, etc.).

 

Trust me! You'll love the 2800 stall!! It's not that high. If you went with a 3800 stall or so, that might be a different story.

But the high stall TC and VB mod will be your two most enjoyable mods! I have had my VB mod for several years and I STILL get a kick out of barking 2nd gear!

 

Yeah I can't wait till I get it all together. I have to replace bent control arm as well. I am polyfilling my mounts too and changing my exhaust hangers. I MIGHT do some chasis foam if I have time. So the car should be quite fun once this is all done.

 

Oh yeah! That is one thing I failed to mention! It's VERY important that when getting your valve body recalibrated, you MUST have good motor and tranny mounts!

If you don't have new mounts, then you have to fill them or get new ones or you will have some issues. With the bad mounts, the tranny and motor will move around a LOT more during the incredibly fast shift. With filled mounts, it makes the shifts feel SO awesome!

I got my VB mod with bad mounts. I thought the tranny was suppose to bang like that during a shift. I also felt the tranny bang when shifting from P to R at idle. It banged b/c it was hitting metal to metal!

When I filled the mounts, it's a smooth shift from P to R now. And at WOT, my 1-2 and 2-3 shifts now feel like a SMOOTH and TIGHT INSTANT SHIFT! ... Instead of feeling like a lose bang of a hammer on the side of the tranny casing! lol

 

Dang, maybe I should install my VB after all....... J/K.....

 

I don't know how the drop resistor feels unplugged. I have heard unreliable reports that when someone unplugged it in their VG Auto, they popped the tranny. But I should better than to listen to unreliable reports. Almost everything I've done to my car, nobody has ever done or tested fully. I go into almost everything prepare to blow something.

The ECU tuning I am currently involved in, nobody has ever done. Emulation is where it's at!

But, I wouldn't imagine that my VB mod feels that much softer versus the drop resistor unplugged.

I think I like the ford one better

 

The ford one looks almost identical. watch it be the same thing lol. I would probably go wtih the ford one since its slightly bigger. and for only a couple bux more. either one is fine.

 

And a better install kit. I thought they were almost the same thing too. I wouldn't doubt it if they are from the same factory.

 

I've had a B&M 16K GVW cooler for a couple of years, with no problems, but the Ford cooler def has a better install kit of accessories. Good find.

 

i cant remember who makes it (i can check if anyone is interested) but i saw a tranny cooler with a fan on the front of it to cool it off during times when your just idling. i guess thats probably not TOO important since the heat is usually during shifts at which point your moving but...just thought i'd throw it out there especially since your spending like 50 bucks on one...i got a hayden for like 30.

 

I have the Hayden one right now. I figured
i would upgrade... 45+8 shipping on ebay.


Its like 130 for one with a fan

 

I used to have a Hayden before, the 403 i think. But realized that the B&M was better and stronger material, i hate the fins on the hayden. I have also been lookign for a fan but nothing yet =\. they are not cheap. i think jime got his fan off ebay but not sure of price.

 

ah i hear ya i guess i can understand where your comin from, the fins do fold really easily on the hayden.

and kevlo i coulda swore i saw the fan cooler one for like 60 bucks, i'll check again.
