R33 Manual Gearbox

[l0WRB]

hey just a quick question guys how much oil would a r33 manual box need 2 fill?

i want to order some redline stuff and dont know how many ltrs!

thanx

[PSI Parts]

From memory it was around 2L.

I just put redline (smurfsblood) in and I it was 3.5 quart bottles (3.3 litres approx), but do a search its been covered before many times, in fact I think I looked it up on here to see how many to order.

thanx guys, just castrol book rkns 2lts as PSI PARTS suggest

but some others say closer to 4ltrs so i got no idea, might just buy 4ltrs, found a guy who will ship 4ltrs for $114 delivered. cheap!

[R32 Driver]

i belive the manual says 3.8L

but i put in 4L last weekend

she'll be right

what oil should i use? im trying to stop my 4th crunching? redline or royal purple? which is the better to use.

Redline did shit all for my crunching gearbox.. absolute waste of money

try a simple gearbox oil change first $30 and see if that fixes it.. Castrol VMX80

btw the gearbox will take around 3.5 - 3.8 litres... You just keep filling until it comes out of the filler hole.. (make sure you undo the filler hole before dumping your old oil)

Ive changed it many times before

ok mate

thanx heaps!

ill let ya know how i go.

I found the redline helped, a noticeable difference at least, I would not go near vmx80...

[Levi_]

Yep just short of 4L.

I tried Castrol VMX80 last time, it worked fine... but I'm thinking of swapping it out with Castrol Syntrax which is the much more expensive fully synthetic product. It's about $30 per 1L bottle at any local auto store.

any reason not to use VMX80?

Its highly recommended on this forum

I filled mine with 3.8l of redline. Only been 250km since the change, so i cant really comment on any difference in crunching/etc (mine doesn't crunch often anyway). Ended up getting it for 22$ a quart .

thanx for all the comments guys

yeah i found a fairly cheap supplier with redline stuff

he is doin me 4ltrs delivered for $112 which i thought was ok.

all the auto shops were around $150

going to get oil change done next week as my 4th is just about impossible to change into unless u double/triple clutch it

just so you know... your synchro is screwed... redline will only prolong its death..

Its not recommended for gearboxes with synchros..

Repco will also do redline for around $115 a gallon (3.78 ltrs)

[l0WRB]

Just a little update.

dropped the oil this afternoon out of the box

and to my suprise 3 syncro clips stuck the to bung

so i aint going to put $150 worth of redline oil in.

i dont know what to do. what are rebuilds worth on these boxes?

Bearings/seals and 4 syncros is around $1500-1600

thats drive in drive out price..

[Shaun]

Around $1500 to rebuild depending on what parts are needed. I havent done it myself, but ive searched in depth on this topic.

Wanna sell your redline oil to me???

lol... i had this exact same problem, 3 clips stuck to the magnet, must be a common problem on the RB25 boxes?

I got gear crunching in 3rd and especially 4th... Just for the record, I use VMX80 for the gearbox and diff, and in my books its a pretty good oil...

either way, looks like ill have to get a rebuild soon..
