Snapped 2Nd In An Rb20 Box.

[Rolls]

So I snapped 2nd in my rb20 box with 260rwkw, I thought 3rd always went?

I guess because i drive it on the street I only ever rev out 2nd, 3rd is just instant loss of license and jail time if you rev that out so maybe thats why it lasted so long and I only broke 2nd.

Thoughts?

Are the rb20 boxes really that weak? My understanding was that you never really know what's going to let go first.

I had a turbo honda that chewed a box every 18 months. The first one I lost 5th and reverse, second one was just reverse. They were cheap enough to throw away though.

Did your gearbox show any warning signs or did it just break suddenly

Revved out second then it sounded like a helicopter at any revs, didn't sieze or explode, but 2nd was missing a whole tooth when we took it out.

Box lasted 4 years of me driving it with that power, no idea how long the previous owner had it with a 25 behind it so did pretty well imo!

at $300 I'll just keep throwing more boxes at it, just a daily I drive to work, doesn't see any track time other than going up eagle on the hill here in adelaide every few weeks..

Was bound to happen. Skinny little things weren't designed for that sort of torque.

So 2nd does go pop in them ? This is the first one I've heard of it happening with.

I've got two RB20 boxes in the workshop with shagged second. As you say, street driving kills second and track driving kills third.

Have 2 aswell that have eaten 2nd. Both street cars with decent power

Time for a RB25DET box, then no worrying about boxes for a very long time.

[Rolls]

Nah costs too much + all the assing around to make it fit, rather just put 2nd hand boxes in every few years.

LOL whatever floats your boat, heard VL manual boxes fix too and are cheaper, but don't quote me on that. I could be right/wrong.

[GTSBoy]

VL (RB30E) is the same box as RB20DET just with the usual slight variation in ratios. VLT is RB25DET box (with same caveats about ratios).

Except the R32/R31 series 3 gearboxes have double synchros on 1st and 2nd, whereas the VL/R31 Series 1-2 ones don't. Not sure on the VLT boxes, but I think it's the same story. Also I believe the N/A R33 and R34 ones are same as R32 ones.

IIRC.
