Best LSD/Diff combo with 2JZGTE setup...

[MKTuning]

I've searched for this information to death and can't seem to find the answer i'm looking for.

What is the best LSD setup to go with a 2jzgte swap? I'm not looking for a drag car, but more of a daily driver with a fair balance between low end and top end power.

I'm currently looking at some NA supras to purchase. Is it a HUGE hassle to replace the NA's diff with a turbo setup? Am i better off finding a turbo supra?

Any help will be greatly appreciated!

N/A come with the option of LSD and all turbos have it.. the last two n/a's i had came with LSD. No difference between the two.

Apparently the stock rear end can hold 850rwhp and some redline to make it last.

They drop out, and the other types bolt right in. What more could you ask for?

it really depends on your set-up. stock turbo go with a lower ratio cause you'll have available low end. with a larger turbo, maybe you should consider a higher ratio to be able to reach upper revs easier. its nice to be able to boost in 4th rather than shifting to 3rd on the freeway.

 

[starscream5000]

Depends on if you want speed or acceleration. That's what it boils down to. Speed? 3.73's or something custom if you want even more available speed. IIRC the MKIV's final ratio is what? in the 3.50's?

Acceleration, 4.30's

Best of both worlds, 3.91's like me.

mk4 is like 3.23. I've wondered about this before but i feel like a 3.73 makes for a more "useful" powerband on a turbo car than say a 4.3.

 

[gilberjj]

mkiv's also have 6 gears.....

 

[starscream5000]

You can have six gears and not have as much top speed available as a five speed. IIRC isn't the gearing ratio on the MKIV's Getrag 1.00:1 in fifth gear? The MKIII turbo tranny is 1.00:1 in fourth, so what's the sixth gear ratio and fifth gear ratio of the two respectively?

 

[NeatOman]

So now you have to find out what is the difference between the MK3 final gearing and MK4?

 

[foreverpsycotic]

Will you be running stock twins in TTC, stock twins in sequential or a single? What transmission will you be using? Power goals? 1/4 mile time goals? How fast are you trying to go (or have the balls to go)?

i believe 5th in both trannies is .75 6th is another overdrive and knocks it way down again

No. 1:1 for the V160 is 5th gear. It is not a double overdrive transmission.




R154

First Gear: 3.250:1
Second Gear: 1.955:1
Third Gear: 1.310:1
Fourth Gear: 1.00:1
Fifth Gear: 0.753:1


V160

First Gear: 3.830:1
Second Gear: 2.360:1
Third Gear: 1.680:1
Fourth Gear: 1.310:1
Fifth Gear: 1:1
Sixth Gear: 0.790:1

So you'd get the most top speed out of the R154 matched up to the MKIV's 6 speed LSD.

can you swap them like that?

 

[Mr.PFloyd]

can you swap them like that?

not a bolt on affair to say the least :biglaugh:

 

[starscream5000]

It's easier to put the R154 into the MKIV than the MKIV's LSD in the the MKIII body.

Or you could go IRS 9" and have any ratio from 2.5:1 to 6:1

Show off

As in Ford 9"?

:werd:

With IRS gears in it (Italian IIRC)
