Hi all,

I've got a R33 non-turbo. I've problems with the gearbox. I can hear a loud crunching noise when shifting from 1st to 2nd. And, also the reverse gear is hard to select. Can i have just these fixed or do I need to recondition the gearbox? And, also at what figure am I looking to get it fixed? Any recommendations highly appreciated.

Shell Spirax CX 80w-90 is recommended (by nissan and they recomended it 15 years ag for r33's so do not use is same for castrol with the nulon adjective is not good its not capable of the gearboxes needs the syncro's with get crused

cross reference this with a redline oil and its a smoother oil and you will thank yourself for paying a little bit more :D

I've done some searching because i'll be doing 'box oil soon. A quick search in SAU says Redline Lightweight XXXX (forgot exactly) is the way to go. There's a few different grades, so do some research before you pick one. It's blue coloured.

My gearbox is rough too. It's not cheap ($3000 new box) to either reco OR replace it so try avoid it unless you have lots of cash :thumbsup:

R338OY is right about the oils :thumbsup:

the make of the oil is called redline lightweight shockproof

the grade is up to you depending on the crunch, when you go to the place take a look at the grades they sell in that type of redline try somthing close to a 80w-90 as i see a lot of skyline guys using that grade. Remember winter is coming up too and the crunch may seem worse so give the gearbox about 500-1000km to get the oil through its system (ive read on the forums the guys say the any gearbox oil needs to coat it for a bit)

around what area are you in?

im on the central coast N.S.W and i guy mine from Bursons automotive

again prices range and i see it inbetween $25 and $33 per liter

i dont know how to fill the gts people say pour it down the shifter and others say that dosnt go to your gearbox so look into that.

i have a gts4 so i have to use a handpump to put my gearbox oil in

cheers, Andrew

Try there first people to look apparently its slightly cheaper if not you will find bursons stock a good range of redline.

gts4 mayyybe a little different, mine is 3.8

if anything yours will be less but not by much only 200ml

Boys Redline is One of the worst things you can run in your gearbox

Only Mineral oil in the box (for eg. Castrol VMX 80)

redline will only wear out the synco more.

it is only a bandaid fix for maximum 1000km...............

If hear crunching........ that means that you syncros are lazy

meaning a recondition is need..............

I know it should cost About $1000-$1500 from Craft differenitials :D

No its not lol we use redline in all our rebuilt gearboxes in high hp cars like gtr etc,

we swear by the stuff .

it sounds to me more like this guy has a clutch drag or the bush in the crank , as reverse doesnt even have a syncro,

ide be checking the adjustment of your clutch if it engages close to the floor then adjust it so its engages about half way along the pedal stroke, and i reckon that will help it to ,

    • Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i. 
    • Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.
    • Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.
    • Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.
    • It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
