Rb25 Gearbox Upgrade

[paul_psi]

okay so I'm looking to upgrade my box to 5 Speed 1st-4th H/C Synchro Gear Set from ppg would love to hear from someone that has 1 to know if it's good. second problem is there anywhere around sydeny that does it wollongong area preferred.

thanks in advance

Why are you upgrading? In my opinion I wouldn't be staying synchro if I was spending that kind of money on a gear set.

I went through 2 boxes in my vl and now my skyline is making more power then what the vl was so if rather do it sooner then later kind of thing. I was thinking dog but I can't even find someone to do synchro

Damn, if you're smashing rb25 boxes you either have over 500kws or you are doing it wrong..

[paul_psi]

vl was on bout 400kw and the sky has been getting tuned for the past week and haven't done the power run yet. got to drive them hard spend all that time and money I'm having done fun when I'm driving lol

[NYTSKY]

Were they VL boxes that broke? What broke in them?

I've gone through a couple of Rb25 boxes, though have not broken the gears, everything around them are what was breaking.

It sounds like you give it a hard time so I would look at going a dog set.

Award diff and gear box build them as well as Advance Motor Mechanics.

they were rb25 boxes the first one I stripped the gearset second one destroyed 2nd and 3rd synchro.

dog will be the way to go and it's not that much more for what it is

hoping for over 500kw at the wheels and I don't want to be babying it lol

Even with a 8k gear set you still have to show some mechanical sympathy. Im at 550rwkw on a stock box.

[paul_psi]

what oil do you run?

does it crunch into any gears?

how often do you drive it?

do you race, drag or drift?

[NYTSKY]

Redline Shockproof (Red bottle)

No crunches

Once a month if Im lucky

Everytime I race it something breaks so now Im just enjoying it

I'm running amsoil at the moment can't remember the velocity 3rd had a bit of a crunch before I pulled it off the road and that was 6 months ago I should get it back from the tuner tomorrow so ill see how it goes with the power
