Hey ZEUS,

I dont think the '32 Gearbox will fit in a '33.

How much power are you putting out? its a fair bit isn't it? Maybe the factory box isn't strong enough?

Most skyline 'boxes will 'bite' you sometimes when changing around 3'rd and 4'th... my 'R and my old Gtst have/are doing it.

Hope that helps.

R32 GTR after 2/92 ie. the pull type clutch will fit.

Getting a bit long in the tooth though and may have similar issues to yours.

Try Redline Lightweight Shockproof.

Worked in 2 GTR boxes of mine and 1 300ZXTT box. Solved the crunchy shift straight away.

Not cheap at about $28Litre and you need around 4 litres.

If it works great and cheaper than o/haul

Cheers

if it is the gearbox....should i be better to get a secondhand one or get my current gearbox overhauled??? i also heard that if a gear is broken..dont bother fixing it coz its too expensive...is that true?

also its going to cost me like $250 just for the gearbox specialist to see whats wrong with it before i even get a quote on the gearbox to fix it.

i just dont wanna spend like 12-20K on a HKS sequencial gearbox :)

why the hell not??? :) :)

with my 'box i just put up with it, it never got worse. My GTR doesn't do it very often tho.

You'd probably be best getting your current one overhauled as you can never tell the absolute condition of a 2nd hand unit.

How bad is the crunching? or does it just 'bite' every now and then?

well basically i dont have that kinda money for a gearbox..:):D:D

4th gear crunches all the time if i shift from 3rd to 4th at a normal shift rate. So what i have to do is slowly shift 4th gear in...(that means like the revs dropping all the way down to 1000rpm...sometimes the car even stalls)

i think the gearbox has had enough of my abuse....

Have the same problem in my 32 GTR box. Have just learned to double the clutch from 3rd to 4th which stops the grinding. It becomes instinctive after a while. Better than $2K overhaul at the moment. You could also try changing from 3rd to 5th then back the 4th which also works for me. Look into an OS Giken crossgear set. Would love to get it myself.

R33 and 32 trans both are the same. Only difference is the push and pull system on the clutch design. I personally wouldnt do what others do and convert it. After all it just is not the same as original and complicates matters later.

What I have done is taken the whole internal out of a 32 box. (comes out pretty much 1 piece and put it onto the r33 box housing. Rumours are that 32 internals have stronger gears or better syncro in 2nd and 3rd? but i cant confirm this. Btw, this is my cars 3rd box since I have purchased it.

yeah exactly what i have to do too...but i find it easier to double clutch from 3rd to 4th gear then going from 3rd to 5th then back to 4th.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
