Do they make different final drive ratios for our trannys?

What about the 4.133 final drive on trannies for the QR25 (spec v) and 2k4 Maxes/2k5 Alti SE-Rs? Will it fit in a LSD 1995 tranny? Any idea where I could find one?

Going from 3.823 to 4.133 should help a bit.

 

It will help acceleration but your gonna be at like 4K on the highway and topspeed will be well below 135MPH. Build the engine to support the gearing; not the other way around. Get 20" DR's and you can get nice gearing that is only temporary.

 

im going to try to get the 3.40 final from a second gen trany in mine. that should not only help with traction issues in first and second but also lower the rpms @ 100mph for better gas milage

 

What about custom gears? I remember there was a thread someone started 2 years back or so saying he found someone who made or could make different and stronger gears for the 5spd. Haven't heard anything since. I would just want a taller 5th so that at 100mph I could be at like 3k-3500rpm instead of 4k or so.

 

I got the gearing i wanted with my car around 4.20 with my tires .If i want the stock gearing i just change the tires.

 

350z guys have an aftermarket smaller final gear for the 6-speed. And I think the 6th gen has a smaller ratio first gear in the 6-speed.

You could always get a custom one.

 

How tall are they and did they really help with acceleration?

 

bf goodrich drag radials 225 50 15 didnt feel any difference

 

RWD cars are a bit easier to swap final drives than FWD cars.

 

Krismax, isn't 225/50 nearly 24". Thats almost stock.

 

Someone tell me how this is "all motor" related?

 

I would definitely call this all motor. The stock gearing is fine for boosted applications. Not many people are into hardcore All Motor setups so different gearing hasn't been done much if any. Gearing is the way to make the car quick w/ an N/A setup. I like the idea of upping the power to match the gearing but that usually isn't possible without power adders. This is a nice throw-back to the Teggy's. One of them comes with this insanely agressive tranny that makes it have a top speed of like 105MPH but it runs low 14's stock(For a teggy thats d@mn fast). I wanna say its the JDM Type R. A buddy has a Teggy w/ the JDM Type R engine but stock GS-r tranny. He is in the process of the tranny swap at the moment.

 

True with NA setups you gotta make every hp count. Gearing and the reducing of upspring weight such as wheels and rotational mass like lightweight flywheels and pulleys cannot be ignored.

 

Well my theory is all motor is motor parts. final drives are located in the tranny

 

Also this section wasn't designed for easy bolt on items like udps and flywheels

True, but there isn't a tranny section. Nor is there a need for one. And for that matter swapping gears shouldn't be taken lightly in terms of difficulty. I think it fits right in here.

I've thought about the possibility of swapping the 3rd gear out in my 6spd with a slightly shorter one to avoid the 3rd to 4th shift at the end of the 1/4. But it's just a thought I wouldn't know where to begin.

 

That's what 1st though 6th gen sections are for.

 

I know what your saying but some things go hand and hand with allmotor like good weight reduction .the fastest all motor cars have some exreme and useful weight reduction tips .

 

OK

I guess it's all in how you look at it.
Personally I wouldn't want to ask this question in 5th gen because of the same reasons this section was made in the 1st place.

 

Wouldn't that be a closer match for the 1/4 section?

 

All motor is basically for 1/4 mile racing. Sure there are people that auto cross and road race but those people don't usually have engines that are creating more than 200 WHP/WTQ without juice or FI. In my experiences all motor nearly always refers to 1/4 mile racing.

 

Um I believe all motor is all motor. Despite what you assume to think it means. If all this discussion is for 1/4, why not just remove this section all together and just discuss all of this in the 1/4 section?

 

I understand your concern as a moderator, but when people are having a conversation about semi advanced technical ways to make their car faster without boost or juice, it should fit in well in the all motor forum. Of course there is no room for "CAN MAH INJUN INTAKE BEET THE CIVIC CUZ HE HAS VTECK AND HE SAYS VTECK NEVER LOSSES"

 

Jeff is gonna ban all of you.
