What should i expect to run the 1/4 mi in with a 3.125 pulley, with the VB mod and tranny cooler, and stillen Y? Just in case, im an 01 i30 (auto obv). I checked the 1/4 mile forum but still couldnt find an answer to my ?. For reference, Burton069,who had just an intake, ran a 15.48@88.86mph. Ideally im looking to hit high 12s, but my main concern is daily driveability and engine longevity, so id prefer not getting any pulley smaller then the 3.125. Is this possible? or would i have to go with the 2.87 to get those times?

Say byebye to the tranny.. If you wanna run high 12's I recommend you do some major tranny work.. 5spd swap??

If i recall correctly, didnt Y2KevSE run the 1/4 12.8@112 while he was auto? I know that was with the 2.87, but with the 3.125 will I at least be in the mid 13s? ANd a 5 spd tranny swap? That doesnt sound like a bad idea, except my interior will look like garbage considering id have to use a M/T console from a max and prob wouldnt fit correctly with my current setup.

Sorry, just had to do it.

Kevish had his tranny significantly beefed up several times, had a full exhaust, and i'm sure lots of other mods. There is like a 20-35HP difference between the 2.87 and 3.125, it's pretty significant. Your car is probubly 50lbs. or so heavier as well. And I think kevina had slick's or DR's or at least sticky street tires.

I'd say a realistic time would be mid-low 14's. Cummy hit 13.9 in his '96 Maxima automatic w/3.125 pulley, and it's significantly lighter then your car. (he also has a y-pipe, vb mod, and full exhaust)

Not true. I think they stopped making manual i30's in 2000, but i'm sure the 2k Max console will fit perfectly, after all they are the same cars, the i30 is just dressed up. If 4th Gen (95-99) Maxima trannies will fit in your car, and If you live close to Florida, PM cbr2. He did my conversion for $1000 which included everything (parts, labor, ect.) He would probubly do your conversion for around $1300. (with you helping of course.)

And if you have ABS, most people don't like to deal with that. It gets in the way and takes up alot of hours taking off and reinstalling.

Kevin had a factory strong tranny (for some reason, I didnt see much metal shaving on his tranny pan when he took out his vb)....he did aVB/Cooler and updated TCM/Solenoid. He has not ran a 1/4 with his ex-SC/auto tranny.

SC with stock pulley might take off 1 second on your 1/4. It adds a lot of highend power but low end is still weak esp with an auto. To get into low 13s with auto, u might need some juice to help you out. SteveChicagoSC hit 13.08, juiced and boosted.


4th gen tranny does fit onto a 5th gen max/i30.

Best E/T on stock pulley : 15.3x consistently throughout the day.
After adding the ypipe : 14.5x (you can see how pointless it is to be blown without the ypipe eh ). There was also a 14.1@99mph but I think either the timing equipment was screwed or my car just pulled a miracle. My friend's 300zx was with me and he was running 13.9's-14.1's all day (and I know I couldn't keep up after running a 14.6 against him lol).

I'm pretty sure my best 60ft is a 2.39, but honestly I don't remember 100% correctly anymore.. I will be returning to the track without my 17x8 on S-03 "bricks" to see how well I can run on steelies.. also with the 3.33" pulley

As far as tranny work is concerned, you likely won't run 12's without beefing up that tranny (it can be done without much work, but you'll probably turn it into fondue before getting the chance to make more than a couple of runs). Try the level10 route or find someone local to build you a tranny with heavy duty clutch discs/bands/etc. A high stall torque convertor would be a good idea too... 3000rpm stall speed tops unless you want to spoil your regular driving routine. I've personally got about 55k miles on my tranny right now - Max Tuning VB, Amsoil synthetics (HIGHLY recommended), and a Hayden 404 cooler. The TCM/solenoid updates/fixes were also performed awhile ago, and I am Canadian just like the beer commercial - thus I have the VLSD tranny (which may be a little more sturdy, who knows).

Also BTW, my best bone-factory-stock time was a 15.898.

Good luck

First time I ran with the SC, I got a two 14.2s and a 14.1, not bad considering going in I was expecting mid 14s. The next time I went the only thing I changed was to lower my front tire pressure to 25psi, that seem to did the trick and I ran a 13.9@100mph. I ran 3 back to back to back 13.9s, pretty consistent. This was with the car untuned. Proper tuning makes a big difference. If I got proper tuning using an AFC at a dyno place, I'm sure I could have hit mid 13s still on street tires.


Btw, I tried to keep the car as light as possible. I took out the spare, jack, ran with the stock 15s, and almost empty gas tank.

You are probably looking at 13.6-14.2. My bet would be 13.8 @ 102. You have no prayer of hitting high 12s with your setup.

Nealoc, Check your PM's.

I was being optimistic saying i expected to hit 12s i see. Personally I'd love to be in the 13s at least with just a SC, NOT ON JUICE. Im willing to spend more on mods, exhaust, torque converter, etc. As I said in an earlier post, daily-driveablity is my major concern. Any suggestions to getting my car in the high 13s will be appreciated.

3.125 pulley with manual tranny, plus some exhaust work (Y,Cat-back,testpipe), and a good driver.

this is my plan.....I will have some fun with my auto SC and then hopefully the tranny will last for couple years. Meanwhile, I will save 50 - 100 dollars a month for a 5spd swap and start to gather parts when my auto is on the way out.

Approx how much would a 5 spd swap cost, using all new parts?

Hmm, n/a I can run consistent 15 flats. What do you guys think I'll run with the SCV2 with the 3.33" pulley, automatic? If the stock pulley knocks off a second in the 1/4 mile, shouldn't I be somewhat high 13's then? Well, right now I'm starting to piece up the tranny conversion parts, hearing about how hard it is to convert with ABS somewhat discourages me, but I think I'm going to go through with it.

I'd say high 13's. With good launches you could probubly run 13.8-13.9's @100+ consistently.

Ok cool, that's what I figured. As long as I hit 13's period, I'm happy.

Y2KevSE did a 5 speed swap...all new parts: AE vlsd tranny, ACT clutch, UD flywheel, etc. etc. 3500 total.....since he did it himself, so the labor is free.

getting used parts will be a lot cheaper....a used tranny is porb. 600 dollars.



but remember, if u have stock cat-back, it will raise up ur EGT fast and u will lean out in just few second. I have a ypipe and it only takes few second to raise my EGT from 500c to 850c.

You should have no problems hitting high 13s. Your car was much faster than mine N/A, yet even I could hit high 13s. My best N/A was a 15.4 btw. With the auto tranny, I was pretty consistent, three 13.9 runs in a row. I had a V1 with the 3.125 pulley though. Besides the SC, I had ypipe, test pipe, vb mod, and catback exhaust.

Yeah, If Ben ran that 15.0 on his heavy 18's, then I'm really impressed. With a 3.125, and the right techniques, I wouldn't be surprised if he gets as low as 13.5 on a cold day, especially with slicks.

I was wondering how quick I was as well. I have a 2000 5-speed max with a V2SC using a 3.125 pulley. I also have a CAI, greddy catback exhaust and a test pipe. Will be instaling Y-pipe as soon as I get some $$$. What do u guys think my fwhp is and how quick do u guys think my 1/4 mile time is. I am just curious. I kinda don't have time to go to the track. Thanx a lot guys.

No no, I ran the consistent 15 flats with my stock GLE wheels, no spare, and no jack. I wish I could run that fast with my 18's.

Ohhh, Ok. Still very respectable times.

maxxboost00 You NEED a Y-pipe. With a 3.125, I am confident you will put an extra 23whp and around 30ish at the crank. I gaurentee once you install a WSP 3" mandrel bent Y-pipe it will shave .4+ off your quarter mile times.

Talk is cheep
