vn diff(disc to disc) into vl

[ucwepn]

will a vn diff (whole setup disc to disc) bolt straight into a vl? or are the disc setups able to be fitted to my existing drum diff?

I ask because vl disc diffs are hard to find but the vn items are sitting in any wreckers and I read somewhere than the vn has a narrow track.

[ucwepn]

also can I use a vn booster/master cylinder in a vl? all vn onwards have 4 wheel discs don't they?

[ucwepn]

I have found the answer to my question and its the vn diff (disc to disc) is 30mm wider on each side than a vl unit, but all the disc brake gear can be bolted on to the drum diff without much hassle.

[Stewart1000]

without much hassel?
mjst be some trouble otherwise people wouldnt buy the VL rear disc breaks would they. only for the higher ratio and LSD...

[ucwepn]

its not the diff I want to swap, I want to remove the drum brakes and replace them with the vn brakes onto my existing diff and axel. all the components are a straight swap I believe, I will need vn discs, calipers,disc bearings, hubs, vl disc handbrake cable and a 4 wheel disc master cylinder. There may be some more bits neede not sure at this stage.

I have already got some turbo front calipers for the front (not fitted yet)so I'm checking prices on 290mm discs.

VN diffs will bolt straight in. they are wider that VL diffs so you'll need the axles shortened if ya wanna have wide rims

[ucwepn]

kewl thanks for that, will vl axels fit a vn diff?

[Boonz]

VN diffs will bolt straight in. they are wider that VL diffs so you'll need the axles shortened if ya wanna have wide rims

maybe some offset rims

[ucwepn]

I wanna keep the 18's that I have if at all possible, I'm thinking just get a drum diff from a vl and rebuild it with vn disc setup, do vn/vp v6 use the same type of master cylinder as a vl 6 cyl na (4 wheel disc)? To use the turbo front brakes that I have will I need a 1 inch master cylinder/booster? or can I get away with just a normal 4 wheel disc one? If I fit the turbo brakes to the front and leave the drums on the back for a while can I use my existing master cylinder?

[Stewart1000]

so that sounds like a much better idea then getting a VLT diff just for disc breaks... one question, how do you shorten the axel?

[Steve-0]

not too sure how to shorten the axle or how wide the rims ya can run but i'd be guessen u could have somthen decent, at least 7" (not sure about 8" inch) with 225's would be my guess.

ucwepn-it would be alot easier just to swap the diffs around unless youre thinking about running 255's or somthen like that which is definetly gonna be too big for the diff

[ucwepn]

I've got 18x8 with 235's and I want to lower it soon, ummm still investigating the options.

[STEALTHY™]

18s wont fit if you put the VN diff in (unless you shorten the axles like mentioned). VN Diff will bolt in, and if running normal rims (like stockies) it wont have a drama.

Also check with your transport authority as to how much you can increase your wheel track, as it might be illegal to go that amount. Especially because its so obvious that its wider.

[Stewart1000]

but how do you shorten the axel???

[ucwepn]

Haha Flared guards aye LOL nah but that would be interesting. Does all the brake gear from a vn diff fit onto a VL drum diff? are the master cylinders/boosters the same?

[hsvhel]

hey man, i just did the conversion and whilst most of it is a straight swap, you need disk bearing collars, which are bigger than drums by about 3mm, it doesnt seem like alot but its essential, and the brake line join where the fixed hoses bolt to the flexi on the main supply, it might pay to check the threads as theyre 4 different tapping holes and it can get a bit fidley, in the end i used the drum ones, same length and everything, any questions pm me.

[ucwepn]

Cheers mate thats good news. I'll no doubt be in touch lol coz I'm hopeless with brakes and stuff, I'll buy all the bits and hand it over to a shop to fit.

[Pistol]

what about the LSDiff? do the vns have them, and can they also be transplanted or would you have the change the whole thing??

[Steve-0]

i think ya gotta stick to the V6 diff so if ya can find a VN V6 LSD then yeah. i think the easiest way would be just to get a VL turbo diff, costs a bit more but ya have LSD, 3:45 ratio, disc brakes and ya can run any rim size

[ucwepn]

There are thousands of vl's around my area and they always beat me to the best parts LOL I have had it confirmed by a mate that all the vn brake gear will bolt straight to a drum diff on a vl. And also the fact that I haven't seen a vl turbo diff or any vl disc diffs for sale for less than $700 helps my decision

[hsvhel]

just dont forget to di the disk bearings instead of the drums, the rollers are the same just not the rubber collar, it will leak if this is not done, i didnt first time round and i wish i'd listened to the old man first time round!

[Stewart1000]

hrmmm well sounds like a pretty good option, any idea roughly on whay size you could run at the most... 8"max width that is?

[ucwepn]

I plan to use the vl diff and axels but with the vn discs and calipers so I will be able to run the rims I have now because it won't change the dimensions.
