with 6.5 and 4.6s your looking at 4200 at 100 in high range from what i can figure

im looking at about 3700

if i go back to 3.7 diffs and get 4.1 transfer gears i will be about 3400

[Fatzook]

is that 4200 rpm on 33's?

[tanshi]

yeah i believe so unless i have it wrong

[remydog05]

Im going 4.6 diff gears for strength over the 3.9's

I also have 4.9 transcase and have 33's but was thinking I might go 35's.

Mine
J20a/AW4/4.9/4.6/31 = 3400 @ 100klms
J20a/AW4/4.9/4.6/33 = 3300 @ 100klms
J20a/AW4/4.9/4.6/35 = 3200 @ 100klms

I did think that 4.1 gears would have been plenty but I got convinced by a mate to go 4.9's
I do have a 1L case here but Im thinking I might be good for Engineering,RWC, Rego etc.

[tanshi]

yours being the AW4 has a much higher gear range though.

the manual is much lower.
aw4 is
1st 2.826
2nd 1.493
3rd 1.000
4th 0.730
5th N.A.
Rev 2.703

5 speed is 3.652
1.947
1.379
1.000
0.864
3.670

[Fatzook]

So my J20 vit runs at 3250rpm @100 on stocko tyres. It has 4.6 diff gears and 1:1 high range. Standard tyre is a 205/65 R16 (26.5").

My ute now has J20 and 5sp, 6.5:1 transfer (20% reduction over standard WT gears), 4.6 diff gears, and 33's (22% taller than stock SV420)

so what RPM will it now do at 100kph? I also have a set of 5.14's for transfer, but there is only a 1.7% decrease in reduction between the 5.14's and 6.5's.....

[tanshi]

with my cals you will be doing 4251.180 at 100 ks in 5th
with 5.1s you will do 4200.870

3.7s and standard transfer you would do 2850.872

3.7s with 4.1s = 3196.861

4.6s and 4.1 transfer your still gonna be doing 3974.476

[tanshi]

standard j20 vit should be doing 3132.498 in 5th at 100

[Fatzook]

shit

[tanshi]

4.3 diffs?

[Fatzook]

How about 4.6's and WT transfer?

[Fatzook]

Pretty rare aren't they?

How would they stack up with a 4.16 T/Fer?

[tanshi]

they arent the most common diffs in the world as far as i know.

doesnt really help alot any way. gives you 3700 at 100

4.3 and a standard case gives you 3300

How is a 4.6 diff stronger than a 3.9 diff?

[tanshi]

i get the impression pete wants to goto a vitara rear diff and housing at some point?

[Fatzook]

Yes I do. Which is why the 4.3 would be the lowest possible ratio I could use for the rear diff.

And I think damo was commenting on Remydog's post

[tanshi]

ahh yeah i should have red that shouldnt i

[Damo]

It answers my question though, so thanks.

[Fatzook]

Anyone know what model GV's had 4.3's?

[tanshi]

there are probably others but the new 3.2 4 door auto has 4.3s

[tanshi]

94-98 2 1.6L MPFI 3 speed auto
94-98 2D 1.6L MPFI 16V SOHC 3 speed auto
04-05 Grand Vitara/XL7 2.5L V6 5 speed manual

also from what i can find

[remydog05]

Have emailed you a gear ratio spread sheet Pete.

Have a look and see what combo you can come up with.

Basicly going bigger tyres puts more load on the Pinon, etc
This explains it pretty well.

Pete
Your j20a/vit 5spd/4.6 diffs with a 4.1 trans.
I get 73 Final crawl ratio with 3600rpm @100klms with 33's

This is very similar to what 00zuk runs

I could live with that.

And thats for the email

[mr.green]

as my motor turned up on a pallet i have never had the standard exhaust ( besides my hyper gonad custom manifold). turns out after a cleanup i have a fair bit of exhaust here off a few different cars, so

can someone tell me the diameter of the standard exhaust tube and also the diameter of them flash extractors some you cool kids have?

i'm after a silent car but don't want to choke it to death like my old maruti running a g16 and standard 1lt pee shooter exaust

[94BAZOOKA]

Could someone please tell me what my rpm will be @100kmh
With. 6.5 transfer and 4.11 diff gears with 33's

[mr.green]

Standard pipe size is 2" press bent. I'm running 2" mandrel on mine for a slight performance gain without all the theatre that larger pipes add

[mr.green]

thanks Pete. do you know roughly the diameter of the header tube? if i get tight and adventurous i might have a go at some
