Oh were to start. There are my findings after installing the 4.083 Gears with Quaife LSD. There is a little noise from the LSD but that is described and addressed in other threads so I won't go into it. I was hoping it wouldn't happen but it did. My initial impressions were I could immediately tell the difference throughout the higher gears(3rd, 4th, 5th and 6th). 6th by the way is awesome now. Before the gear change I had a problem with speeding I will admit that I have a heavy foot and would constantly catch myself doing 90 cruising down the freeway. After the swap no more of that I cruise at 75 which takes care of that and having to constantly watch myself due to the lack of cruise control.

Gas mileage, im getting 26mpg on the freeway crusing at 75 to 80 through out a full take of gas. I had a 5 hour drive so it was easy to gauge that. City driving isn't to bad either im getting 19.5 right now with driving around base here at Fort Leonard Wood. So that's pretty much consistent stop and got never going past 35mph.

Now track experience. I took it there that night. 60ft times were terible I couldnt get traction in 1st and wheel hop was a pain. Oh and I only had a chance to get to a 1000ft track..

2.11 60ft 11.12@96.73 1000ft time.

This is with no other mods and appox. a 1/4 tank of gas. It pulled hard all the way the the end of the track. I was even told I have to wear my helmet now which is pretty cool because I have never had that issue before.

Anyway just thought I would post my thoughts.

I can't really think of a better mod.

edit: I have some video footage and time slips I'll try and get added later.

 

What made you go with higher gears?? I want a quaife for my base so bad it makes me sick... but i cant justify it.. It would just get me into more trouble on the street and i dont track at all......of any kind.. good read tho thanks!

 

I did the solid diff mount at the same time. Helps a ton with wheel hop.

 

If there is one single mod a base Z should get over all others, its an LSD.

 

That is real impressive to do that with just gears.....

 

Trust me.....I know. It was THE first thing I looked at after I bought it. Then I decided to get used to the power, then I would get it. then came a speeding ticket-got dropped with traffic court-then came another---awaiting court

I want it sooooo bad but my feet have some growing up to do before I trust them with an LSD

 

I'm kinda wondering what an LSD has to do with traffic tickets. If I feel like accelerating through a turn, I can punch it much harder before losing traction so if anything I'd think it would contribute to *less* reckless ops tickets.

 

Well I'm saying that since I don't have an LSD there's NO chance I will try any spirited turns/u turns.

I take my Z and gf out to julian ca where there are some twisties. pushed the limit of the open dif(not hard) and scared teh gf 1/2 to death by gettin a lil 1 wheel drift action comin out of a turn... she said "we arent going back out there unless you get that LSD thingy"

Maybe I should just pull the trigger


When I pay my cc debt back off

 

hmm 11.12 1/4 mile time....

 

<--Doesn't get what you're saying..

 

interesting times

 

Glad to see your review, I have an 07 base as well with 4.08 gears and quaife awaiting new bearings for the install.

 

What tires / size were you running the 1000 ft times?

 

meaning if it the 1/4 mile, he be the fastest n.a Z out there..... and honestly i dont get how he would hit that time of 11 with out boost and the 4.xx wouldnt be good for boost.

 

What are you blind? He clearly states it's not the quater mile time...

How about you read next time?

 

Alright anyway back on track.

I am currently running shitty Nexan 3000 245/45/18's

They came on the car.

As far as why I switched the gear ratio well considering they are gears so high for N/a I figured pulling the gear ratio closer together would give me more power through out the gears or more access to it if that makes any since. In case it didn't to circumvent flaming I know that the HP numbers do not change with a gear change.

 

O, well im sorry. I did read but i guess i miss understood what the 1,000ft track ment....

 

Did you get the gears installed at the same time as the LSD? Just curious if you knew whether the sound was from the gears or the lsd.

 

Never really thought of that. Hmm I did both at the same time.
