I Have a Nismo 4.4:1 final on the way and was wondering if anybody has this ratio or close to it with the KA Trans.

what is your speed in 1st and 2nd at 6500?

with 205/55/16's I am hitting 80 at the top of 2nd. trying to get this down 10-20mph. I will be adding 4.25% to the overall diameter of the tires when I slap the 225/40/18's on there....

this car spends 90% of it's time in the mountains and on back roads...I don't care about gas milage.

Thanks for any info---

Why would you want 18s? I think it's been established that 17"s are the best size for any type of sport usage.

Because 18's are awesome, thats why

Ok, who established that and why?


The reason 17's performance was "established" is because of the stock gear ratio change made by an 18".

A low profile 17" tire is actually smaller diameter than stock which increases torque.

BUT! If one was to change the final drive to a 4.4:1..... all that "Established" 17" info gets tossed out the window!

Thanks, but I wanted info, not your opinion on what was established. :wavey:

I have the 4.36:1 gears. My speedo is off from the ratio change so I can not tell you exact speeds but it is noticably shorter. I usually start in second now since first is so short. It feels good with 205/55/16. With 225/45/17, you can tell there is a loss in torque compared to the 16s, but it is still better than stock. I don't know what else to tell you but I like it.

actually the bigest wheel you want to run is one that clears the brakes, and no bigger. anything bigger is either for A. Style or B. so you can run smaller sidewalls and deal with sidewall deflection of shitty street tires and weak ass sidewalls. I'd rather strech a tire, or get better ones than having all the other downsides of big rims.

You can use several calculator available online for calculating wheel speed. Search for them on Google.

If need be, I can fab up a spreadsheet for you easily. Let me know.

I disagree. Not trying to flame at all, just have a different opinion.


but that is for wheel/tire discussions.


I just wanted to find out what people thought about the nismo 4.4:1

RightWheelDrive: Thanks, that was the feedback I was looking for.


everyone on this forum is soooo quick to add off topic comments and yell at you for not searching. :hammer:

I didn't yell at you for searching. I'm just saying the calculator is available everywhere. It should take you no more than a few minutes in Google.

You could have had your answer days ago, instead of bickering with people over searching.

I've got the 4.636:1 FD in my S14 and I love it! Cruising in 5th at 80mph with 255/40/17 puts me at about 3800rpm.

Endless88, he wasn't the one who repped you. I just checked your rep list. Not that it really matters just thought you'd like to know it wasn't him. No, I won't tell you who it was, but it wasn't him. :bow:

If you're really looking to shorten up your gears stick with 15's! Why so skinny out of curiousity? If you went to a 225/50R15 with that short ol final drive you'd have some quick shifting to be doing.

Where can I get a nismo4.4:1 fd and how much does one of these cost? I think it would be better for dragz with my n/a ka.

Thanks! I have extensive calcs that I use for regearing jeeps.
I Have all of the ratio's of each gear in my transmission, the final and the overall outside tire diameter. But, honestly I was more interested in opinions and personal experiences.

I had a 4.11 I think (not 100%sure cause it just came in a VLSD), but it was AWSOME with NA/KA. Much more enjoyable to drive. I an still holding onto that VLSD just for the final drive, and I plan on putting it into my racecar with a welded. I dunno if its worth the money new from the factory though....those things are pricy.

4.36 is amazing compared to 4.08.

J5 had one in his car for a while, Lightly modded N/A KA with a 4.3 opposed to stock SR with exhaust and 4.08 and he stayed right with it till middle of third. riding in it, it feels more eager to pull everywhere.

about the only time you won't want a bigger ring is over 350whp.

Courtesy Parts has the "Nismo" ring gears for like 400$. which are just new OEM rings from various things, E-SR has the big 4.9+ Rings for the N2 cars.

3.9_ is J30
4.08 is UDSM 240sx
4.11 is some 180SXs I think
4.3 is CA18 Turbo cars
4.6 is Early CA18 N/A cars.
4.9/5.19s are from the old 4 speed datsuns I think

No one actually tools and makes their own rings, so if you try hard enough you can find it somewhere. ie. J's Racing's S2000 rings are Mazda ring gears.

my s14 comes stock with 16's and they already look small. not to mention, 17" are cheaper than 16's Not looking to have a top speed of 80mph in 5th....:D

I have a used nismo 4.4:1 that should be here this week. can't wait to put it in!

Mountaingarage, can you please ditch the "nismo" ebay terminology? Read McRusselPant's post and realize that it's just a stock diff offered in another car.

hmm, maybe a 4.11 should be a good little upgrade. Not sure a 4.3 will be needed as I daily drive my machine...

^^^4.3 isnt that crazy. 4.6 is kinda quick but a 4.3 is just right for 300 or so hp

^^^ shows what fd in what model

i have a 4.36 vlsd that was the first mod i did to car
for a stock ka, this is an awesome diff
ive driven about 2 years on it since
no complaints, not 'crazy' short

i think if i didnt drive the car on the freeway i would put in 4.6ish gears

btw 4.36 is 9% shorter than 4.08 ==> about 5mph difference @50

RightWheelDrive

Yes, 4.36 is the shortest I would go for a daily driver since it revs pretty high on the freeway. It feels really good when you want to have some fun. I was able to keep up within two car lengths with my friend's boxster to the middle of third. That was with a NA sohc.

I won't neg rep you for trying to embarrass me....it won't work, I 've been around too long to worry about your silly comments.

...btw - It is NOT a DIFF, it is a ring and pinion gear set.


For Flyberts clarification:
The Nismo Part that I have been refering to IS
The 4.364 Ring & Pinion Set Code Number: 38100-00004
Courtesy Nissan Price:$482.34
