hey all, i bought my r32 with one of the bearings destroy(metal pieces everywhere) which in turn rendered the box useless, i had another rb20 box installed $750 all up.

But now im seeing that this new box has a small whine nothing too bad, but today was the first i actually gave it in 1-2-3 gear, and when it into 2nd it went in like it was going explode if i did it a few more times. Are all 20 box's like this, or is this box probably stuffed aswell?

thanks

It feels so bad when going into 2nd quickly, im not snapping it in but just fast, feels like its not far from crunching, the box just feel weak. Im curious if this is like all the 20 boxes.

wrong.

Its the same box as whats in most of the 5 speed RWD cars, except R33 GTST and Z32 twin turbo IIRC.

It shouldnt feel like that, if anything it should feel better than an RB25 box on quick shifts. Lighter gearsets and components would make it easier to change between cogs.

That box has a problem. I can shift like an absolute MOFO in my S14 (and every other 5 speeder I've driven) and it is the same box. It could be the clutch, but you should take it back to the mechanic and get them to sort it out.

And R34 GTT.

All the 20 boxes I have driven with (4 from memory) have felt extremely fragile in comparison to the 25 box. That said, Scott knows more about these things than me. Best get it checked out.

Yeap, I wasn't sure about the GTT as I know it comes 6 speed lol couldnt recall if there was a 5 speed model also, but am sure they would use the same box as the 33.

The smaller 5 speed is definitely pretty fragile in comparison, but shouldn't feel like its going to explode. Should just feel lighter to work with than the bigger boxes, and like I said should shift easier/quicker with less effort.

If i were you id be diluting the gearbox oil with some engine oil, thats what i did and my box went from crunching, jarring and needing a rebuild to now being smooth and awesome :yes:

If the oils too thick or its overfilled it will not help.

Fwiw certain trucks use the same oil for the box as they do for the motor (5w30) so the motor oil suggestion isn't a bad thing and can help.

Personally I would take it back. You paid good money and got a shit gearbox.

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts

    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
