4.36 gears

brucelidat · 11-04-2014, 03:19 AM

I juts noticed that z1 has 4.36 gears for the 370z. When did this happen and does anyone have them? I have 4.08s already. Just wondering how crazy 4.36s are...

Is there big difference of 4.08 gears compared to stock ?
I ordered 4.08 gears and waiting to be delivered

I don;t know whether you could call it "big", but it is certainly noticeable.

I have not had my car onto the track since fitting the 4:08:1 gears and that will be the real test.

my big worry with the shorter gears are that i would be messing with the gearing for the road courses. let me know how it goes and if you think going up another step would be a bad thing.

I'm not going up, just wondering if anyone had them and what they thought.

1slow370 · 11-06-2014, 12:52 PM

Fixed

Bringing this back up since I am looking at these. Any reviews on this yet? Bruce, how much did the install cost and where did you get it done at if you didn't do it yourself?

For road course usage, 4.36:1 makes 1st gear redundant and in effect gives you a 5-speed gearbox with reduced Vmax.

With 4.08:1, I don't use 1st to start, which gives me a single gear from zero to 100kph. 4.36:1 would be crazy short ...

Speed in gears with Nissan box and my DD tyres at 7200rpm is:
1st 40mph
2nd 64mph
3rd 91mph
4th 117 mph
5th 148mph
6th 156mph ** at 6000rpm ***

With my 645mm tall track tyres, speeds are

1st 35 mph too slow to be any use, so I start in 2nd
2nd 57mph
3rd 82 mph
4th 110 mph
5th 140mph
6th 159mph *** at 6500rpm ***

In my case, I used to see redline in 5th at Phillip Island GP circuit with the 3.7:1 OEM ratio but ith the 4.08:1 ration I have to use 6th and pull somewhere between 6300 and 6400 rpm down the chute into T1, so the 4.08:1 has made a very significant difference in acceleration and Vmax.

I would reckon that unless you can safely turn your engine to 8000+ rpm (means dry-sump) then a 4.36:1 diff will not help on the track - might be useful on the strip though

I am now playing with options as I have a box with a much taller first gear and a 0.878:1 OD 6th .... so looking at tyre sizes to suit (650mm tall vs 665mm tall vs 675mm tall Dunlop slicks).

l33t has them in a manual

Japanjay · 11-19-2014, 09:43 PM

I have redline bumped to 7.7k. this would be used solely for the strip.

maizenblue · 12-18-2014, 12:24 PM

anyone have any more info on these? trying to decide between 4.08 and 4.36. im looking for straight line acceleration, not so much track use. ive heard the 4.36 isnt so great at higher speeds

dimitarm · 12-18-2014, 12:29 PM

just installed 4.08 gears, it makes the car beast.
i think 4.36 would be too much.

After the install my speedometer is not working and the abs vdc lights are on.
Any idea what can be the cause of this?

Here are the error codes that i get

maizenblue · 12-18-2014, 12:42 PM

Im thinking a wheel speed sensor was broken or unplugged on install
