New PB = 14.56 @ 94.10 mph
Took the car back to the track last night. Weather was very nice for racing.
Temp: 57, Humidity: 57%, Baro: 29.93, Crosswind from the W at about 10-15 mph (track runs to the north).
First run straight off the street w/ street tires on: 14.77 @ 94.85 (Intake temp: 106 degrees) 2.28 60ft
Second run after letting it cool and putting DR's on: 14.56 @ 94.10 (Intake temp: 86 degrees) 2.20 60ft
Third run , same conditions as 2nd: 14.58 @ 94.14, 2.22 60ft
After the 3rd run I didn't have near the time to let the car cool down and times started to get slower.
4th run : 14.78 @ 93.98 / 2.26 60ft
5th run : 14.81 @ 93.61 / 2.29 60ft
I was running 91 octane instead of my usual 93. I noticed at the beginning of the night, while waiting in line, the timing stayed at 15 deg steady. Towards the end of the night, when my times started dropping, it was running at 9-11 deg. never getting back up to 15. I'm thinking maybe the motor got heat soaked and started to knock a little bit, since there was no time between runs to let it cool off (last two runs). This was the last race of the season, and I tied for 3rd in the points totals for the year.

I hope you can make up to KCIR one of these Sundays in November.

Sunday racing may be doable. That's about the only day I have off work anymore.
I ran my MEVI in almost every imaginable weather and could only get a 14.84 out of it. I am totally convinced the '00 VI is superior to the MEVI. It's hard to say though by looking at my set-up just how much better it (just the VI itself) is since I'm running the '00 TB and no EGR. Oh well though, all I know is my car feels great and it's running faster than it ever has.

Good runs! Looks like the 2KVI is turning out to be worth it for you. I would be curious to see a couple of you best MEVI slips and 2K VI slips. Don't have to post the actual slip, just the #'s. I am curious as to what part of the 1/4 your seeing gains over the MEVI.
Were you warming up the tires?

Here's some slips to compare:
RT:........0.876........0.8183........1.0154...... ..0.8385........0.7167
60ft:......2.2595.......2.2686.......2.2698....... .2.2887........2.2079
330:......6.3027.......6.2814........6.3023....... .6.2899........6.1191
1/8:......9.6281.......9.5876........9.6190........9 .5796........9.3571
MPH:......74.45.........74.70.........74.51....... ...75.07.........75.52
1000:...12.4932......12.4464......12.4833.......12 .4242......12.1683
MPH:......85.11.........85.34.........85.19....... ...85.61.........86.65
1/4:.....14.9432......14.8804......14.9169.......14. 8482......14.5669
MPH:......92.11.........93.05.........93.30....... ...93.55.........94.10
The first four are my fastest slips with the MEVI. The last one is my run Sat night with the '00 VI. Here are the weather stats for each run: (temp, humidity, baro)
1) 63, 70%, 29.80
2) 70, 63%, 30.06
3) 72, 59%, 30.05
4) 76, 48%, 30.04
5) 65, 40%, 29.91
I'm running B/F Goodrich Comp T/A Drag Radials. I haven't started playing with the pressure's in them too much. All runs have been done at around 24 psi. They grab well off the line and aren't too low for the top-end. I know a lot of 5-speeds run a lot lower than that but I don't know if there are any other auto's running these. I may do some experimenting if I can ever make it out to some Fun Drags. All my runs this year have been in competition so I didn't want to screw up and get knocked out cause I was messing with the pressure in my tires.
EDIT: I just realized the weather info for my VI run differs from my first post to this one. I went back and double checked it and the info in this post is correct. Don't know where I came up with that first one at.

The biggest difference is the 60' time, but that still doesn't make up for the faster time. I would guess taking traction into consideration that the 2KVI gave you about .15 and a 1mph over the MEVI. Were you on the same rims and tires with the MEVI runs?
Good stuff and thanks for posting the info....this is how we learn, when guys are willing to give us info and get results.

I had the car set up the same for the MEVI and the '00 VI runs. Same tires, same tire press., etc. I had exactly 1/4 tank of gas Sat. night and all my best MEVI were with the needle just over the empty line. I usually drain my tank at the shop before going out but work kept me late and I didn't have time. I was trying to get any variable that I could control as close to my MEVI runs so it'd be as accurate as possible.
Generally, with the MEVI, I'd start the night with around a 15.0-15.1 and progressively get faster through the night. So you can imagine the smile on my face when I get my first slip and it was a 14.7.
A 14.7 with a hot car, street tires, and more gas than usual; I knew it was going to be a good night.

Foot on the brake, bring the RPM's up, on yellow slam the gas as I release the brake. We run on a .400 Pro Tree (I think that's the name). All three yellows, then green. I like that tree a lot better than the other one.

Huh who's your daddy 
The 00 vi is what ive been telling you guys all along i go from mid 14.60's to 13.80's with DR's and the 00vi and i im convinced the DR's take from me 1 to 1/12 mph away.
Well you guys all had a chance to buy my VI . And i know to people who will have the 00 vi on within two months.

Cost is very dependent on where you get your parts. I got an entire '00 engine and auto trans on Ebay for $465. The trans had a small hole in the case so the guy threw it in with the motor. Just have to keep your eyes open.
As far as the ECU goes, I believe you can get the JWT in a '96 ECU to work. Hell, even if you can't get an ECU for your car, it's going to improve it. Not as much as a car with the extended rev limiter, but it will definitely be better than the OEM manifold. People who couldn't get the ECU used to be scared about the loss of low-end torque with the MEVI. I believe this could be the solution.

Why there makes such a difference, I don't know, but it works. The low end torque is the best thing about this VI. In town driving is so much better.

And nissan states the composite manifold is much smoother inside over the aluminum

I'm using the '00 TB and the '00 IACV. I had to get rid of the EGR to do this though, because the '00 IACV sits underneath the TB and was hitting the EGR when I tried to put the TB on. I just wired the '00 IACV plug in place of the 4th gen one and let the ECU figure it out.
I do have two problems with this set-up just to give everyone a heads up.
1) Sometimes when I start the car, the rpm's run at about 1500 and stay there. When it does this, I turn the car off and restart it and everything is normal again.
2) There's no idle adjustment screw so sometimes when I stop at a light or in traffic, rpm's dip to 400-500 and then come back up to around 800. This causes the lights to dim a little and the first couple times it does it you think it's going to die. It hasn't died on me though. I tried running the throttle cable tight to bring the idle up but had issues with it wanting to race really high just out of the blue. It's much more manageable this way.
Not trying to scare anyone away, just don't want anyone to be suprised if there car doesn't act like it did with the OEM manifold on.

You have to have the piece made for the 4th gen IACV to bolt to. I didn't have that piece so I just used what had. Only piece I had to fab was the small plate to cover the EGR hole in the bottom of the manifold. It really hasn't been enough of a problem for me to worry about switching over to the 4th gen IACV. Krismax and I discussed different ways of mounting the IACV, I just haven't felt the need to mess with it. The car idles at about 800 rpm's just about all the time, with the exception of those two glitches I spoke of. That's perfect for my auto with PR engine mounts.
I just wanted people to know you can use the '00 TB and IACV, but also let them know of the issues associated with installing it this way.

Wow after seeing your times and you posting the temps and humidity and how they effected the run, I feel a lot better. When my 04 6 speed was stock I ran 14.3@96.5 in good weather probably around 60 with sub 50 humidity. Since then I have added I/E/UDP and I ran a best of 15.1@94 the other night. Temps were around 78 and humidity was 80+ as the night went on. Now I know its just the temps causing my crappy times. Cold front this weekend and im headed to the track.

If you don't want to use the EGR, I suggest you try to use the 00Calispec or 01 VI because EGR is built in. It might be harder to figure out how it works but might as well try it.

The first tank I ran through was horrible. Somewhere around 250 miles on that tank. So I bought a V-AFCII to control the manifold changeover and tweak the A/F ratio. About a month after the instal I finally got to the dyno and I needed no tuning. They said the A/F was fine. I hadn't checked it since the first tank so I guess slowly the ECU adjusted itself. Last highway trip I took, I got 426 miles on that tank. I now have a $300 rpm switch.
