hey guys i got a ppg straight cut dogbox and using the redline lightweight shockproof in it at the moment, im finding when its cold it drives smooth as but once warm it tends to crunch abit even when driving it hard, its a very very new box so shouldnt be anything wear and tear related i hope, im thinking either the oil is wrong type and getting too thin when hot? 1st to 2nd when giving it a boot full is a big cruncher too i cant stop it :)

any info appreciated

You have a dog box and your worried about it crunching? Am i missing something here?

Maybe he's referring to a straight cut gearset (ie. first 3 gears replaced).

unique1 are you referring to a dog box or straight cut gearset?

Thats just the way they are. id be using a heavier oil. ie heavy shock proof. thats what i use.

1st to 2nd is always harsh, you will need to revise your driving style .

the oil is nice and thick so the gears slow down quicker till everything heats up.

they are a pain to rev match. just practice dude.

yes its a ppg 1st to 5th straight cut dogbox, i know they arnt a smooth ride but i was just curious as to why it was perfectly smooth when cold but worse when warmed up. Thanks Dave, i just wanted to make sure its nuthin bad and im causing more damage, ill swap the oil over asap and see how it goes, i can get it to drive smooth as without any crunching except the 1st to 2nd shift :) if i go slow 1st to 2nd its fine but when revving it right out it crunches bad.

im definately getting the hang of it now i dont mind driving it at all even around the streets its fine and just has abit of a whine too it that gets on ya nerves sometimes lol :thumbsup:

      From Japan and back to Europe, my sh*tbox R34 GTT

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
