How Strong Is R33 Gtr Series 3 Standard Front Diff

[Daz]

Hi,

My car has over 400rwkw's (closer to 500), the car is only really used for street duties with some hard launching (looking to take it down the drag strip soon).

My question is how much stronger is the standard front centre diff compared to lets say a nismo pro 1.5 way or a quaife 1.5 way?

Is it worth changing?

How much power can the standard front diff take?

I dont want it taking out my bottom end or new sump if it goes...

Thanks

Darren

More to the point, with near 500rwkw it must walk all over the place coming on boost ??

An LSD will not only help get the power down, but help keep it straight.

Obviously they are stronger, not sure how long a standard front diff will last at that power.?

[Daz]

Yeah walks all over the place, starts getting better traction from 4th...

Think you have sold me if its going to keep the car pointing straight.

I havn't really heard of anyone blowing one.

I havn't really heard of anyone blowing one.

I have seen at least one (maybe two) reports of failed front diffs so

1. it's not very common

but

2. it does happen.

If I had the money I would get a Quaife front diff - those who have done it seem really happy with the improvements.

A Series 3 diff is no different to anything else, they will break if you put sticky rubber on and that's what it comes down too. How much traction you have or don't as to what you will or won't break.

I broke mine with 370rwkw and drag radials after about 20 passes (no wheelspin on launch 8200rpm), that said it had done 300+ launches before that on street tyres.

The joy of a front diff breaking is that it can, and in my case, take the sump with it which is a motor out job to fix.

What broke Ash was it the diff center gear or, pinion?

[R31Nismoid]

From memory, everything. Nothing was reusable and the pic i remember seeing had chunks of metal everywhere

So just got a Nismo centre to replace it. Grip so far improved on street tyres was worth it and should've done it sooner.

I'll find out if anyone can remember more specifically what broke (if it was one bit or everything).

[tricstar]

Regardless of what brakes on the standard one, you need an after market with that power and hitting the strip.

Quafies seem to be pick of the bunch ATM, but I have an OS giken 2 way which works a treat everywhere. What ever you get you'll love it, grip is amazing.

And if you're not getting grip now until 4th ? What sort of plastic Tyres are you running

How is the 2way coming into corners? Not an under steer pig?

[Daz]

It's most likely going to be a quaife but I've also seen a nismo 1.5 and nismo 1.5 pro. Is the pro much better then the standard 1.5?

[Piggaz]

My understanding is the Pro is adjustable where as the normal 1.5 is not.

Not an under steer pig?[/quote<br /><br />Yeah now that you mention it, I did used to get a bit if under steer on really sharp corners, hairpins Etc but no more than my previous GTR with stAndard diff.<br /><br />since installing the "Full Race 4wd controller" I don't get any now. <br /><br />But yeah maybe 2way is not the best option for most.
