hey i posted this in classic skylines and have got no response... after a closer look i found this thread... im new here so i didnt know it was here.

neways all that aside, i have an rb20 auto box that tends to flare between changes. if u drive sedatley it is only just noticable, if you rev it out to 4 or 5 grand then it tends to take ages to shift from 1st to second, and occasionaly from second to third...does the box have bands to adjust the clutch packs? im new to skylines so i got no idea about the r31's. any help would b great

thanx

grant

this happend to a mate's mrs's silvia non-turbo auto. Thing revved out before it could change gears. she eventually had to replace the gear box (could have been rebuilt, but got a replacement for like $250).

Try changing your trans fluid to some high quality stuff possibly from the redline range and get your filter done at the same time (basically a trans service, but u should supply some good tranny fluid) and see if that helps after a few days. You might be able to salvage the box (possibly for like a few more months or something)

There is also a pin which who ever services it will know about, that will determine how smooth the changes are, he will be able to put a longer one in so that the changes are harder but the box should last longer.

U don't have much time before it just goes on you. Service the auto as soon as you can and whatever you do, don't thrash your car!

      R34 Gtt Wheel Offset Advice

      By GTSBoy · Posted

      I think my main complaint with your idea is that there is a veneer of idealism spread across it. You want the simple numbers to make it easier, but all they will do is make it easier for someone to come to the wrong conclusion because the fine details will kick them in the nuts. As it is right now, the tiny bit of arithmetic is NOT the obstacle to understanding what will fit and what will not fit. The reality of trying it is what determines whether it will fit. If you had a "standard rule" that R34 GTT guards have that magic 100mm space from the hub face to whichever side you were worried about, and someone said "excellent, this wheel is only 98mm in that direction, I'll just go spend $4k on them and jam them on my sick ride".....they would just as likely find out that the "standard rule" is not true because the rear subframe is offset to one side by a fairly typical (but variable) 8mm on their car and they only have 92mm on one side and 108 on the other.

      R34 Gtt Wheel Offset Advice

      It still combines inches with mm, especially when you have .5 inches involved, and mm and inches that can go in either direction. This would give a clear idea on both sides of the rim, right away, with no arithmetic. Even better if somebody gives you the dimensions of the arch of multiple cars. i.e GTR may be 125mm, a A80 Supra may be 117mm, or something along those lines. Yes, you can 'know' that going from a 10in rim to a 10.5in rim with the same offset moves both sides about 6mm, but you still have to 'know' that and do the math. Often it's combined. People are going from 9.5 +27 to 10.5 +15. You may do the math to know it, but if it was going from (I had to go look it up to be sure) 241mm/2 - 27 - 93.5mm from the center line to (more math) 266/2 - 15 (118mm) from the center line. Versus 93mm vs 118mm. It's right there. If you know you have a GTT with 100mm guards you can see right away that one is close to flush and the other absolutely won't work. And when someone says "Oh the GTR is 120mm" suddenly you see that the 10.5 +15 is about perfect. (or you go and buy rims with approximately 118mm outward guard space) I think it's safe to say that given one of the most common questions in all modified cars is "How do offsets work" and "How do I know if wheels will fit on my car" that this would be much simpler... Of course, nothing will really change and nobody is going to remanufacture wheels and ditch inches and offset based on this conversation :p We'll all go "18x9+30 will line up pretty close to the guards for a R34 GTT (84mm)" but 'pretty close' is still not really defined (it is now!) and if you really care you still have go measure. Yes it depends on camber and height and dynamic movement, but so do all wheels no matter what you measure it for.

      But offsets are simple numbers. 8" wheel? Call it 200mm, near enough. +35 offset? OK, so that means the hub face is that far out from the wheel centreline. Which is 2s of mental arithmetic to get to 65mm to outer edge and 135mm to inner. It's hardly any more effort for any other wheel width or offset. As I said, I just close my eyes and can see a picture of the wheel when given the width and offset. That wouldn't help me trust that a marginal fitment would actually go in and clear everything, any more than the supposedly simple numbers you're talking about. I dunno. Maybe I just automatically do numbers.

      Sure! But you at least have simple numbers instead of 8.5 inches +/mm, relative to your current rims you do maths with as well, and/or compare with OEM diameter, which you also need to know/research/confirm..
