lsd and cam gears

[eryc]

is it posible to fit lsd to a r33 n/a

if posible what parts do you need

will one off a gts-t fit

and does a r 33 gts have vvt which

means you can only fit adjustable cam gears to the

exhaust side and how would you tell if it has vvt

thanks eryc

Yep, you can fit a LSD to a R33, I fitted one to my R33 GTS25 a couple of months back made. The diff I got didn't come from a skyline, not quite sure what it came off (but it was nissan). Every thing was the same except the mounts at the back of the diff, I just changed the back plate over from my old diff and that fixed the problem.

Series 1 R33 don't have vvt, not so sure with the series II, I think they might have vvt.

i heard differently, RB25de has vvt on the inlet side, S1 and S2 engine dont change.

[crooser]

correct... both series of 33 gts25 have vvt

i believe its only the first 25des in the r32 gts25 that didnt have vvt

a lot of r33 gts25 (type s) manuals have 4.3:1 lsd standard.

I actually killed my 4.3 lsd and simply swapped it for a 4.11 lsd from a gts25t

cheers

[eryc]

how easy was it to swap over to gtst lsd

did it just bolt on or did you have to modify

thanks eryc

Are you sure about all the R33 GTS25 having vvt?

so why the power difference in power between series I (142kw) and series II (147)?

[nismoman18]

i think theres a power difference between R33 RB25de and R34 RB25de mate, not the s1 and s2

[nismoman18]

im just wondering how do u know if its an LSD ?

Thanks for clearing that up for me;)

[eryc]

kyla there is no way you could find out what your diff is off? could you?

thanks eryc

[eryc]

sorry left the s off

skyla

[eryc]

ok took the cam gear covers off

on exhaust side has a 5 spoke cam gear(not adjustable)

on the inlet side has large pice of steel with a cover bolted to it

wich apears to be bolted to the centre of the cam gear (all most same size as cam gear )this i guess is the vvt

please can some one tell me if i am correct

and also if you wanted to put adjustable cam gear on can this be taken off or is it the same thing

thanks eryc

Sorry dude, I've had no luck in finding out what it was off.

The ratio of the diff I got was 4:3.1 ratio LSD, but knowing what I know now, I should have got a 4:1.1 ratio LSD, it would have put the speedo readings out a little bit, but the car wouldn't rev quite so high at 100km, and I would have a better top speed, I'm kickin my self now:hellpisd:

If you are getting a LSD check what type of flanges (the ones from the diff to the wheels) you have, before you go and get one. I made the mistake of not checking the first time and got the wrong one:Oops:.

I have attached a quick sketch, of the diff flanges sort of looked like the first one in my case was the wrong one (can't quite remember if it was 5 or 6 stud), the 2nd was the one that fitted my car. sorry I can't be of more help.

i guess mine is LSD then cos both my wheels always spin. LSD isnt locked though is it! i hate open diff's they suck

[Greg]

"7grand clutch dump, if both wheels spin u have an lsd if only one spins u dont have an lsd."

LOL yeah that's the fun way, the more restrained and kind way is to get the car on a hoist or jack it up and turn one (rear) wheel . if the other one turns then you have a LSD.

[nismoman18]

ok well thats mine then cos my mechanic did that, come to think of it he mentioned mine was LSD :S gees im dumb

[Greg]

can anyone tell me what is going on here: i have an lsd, but if i have one wheel on grass/dirt and one on tar and i go to take off, it just spins the wheel on the grass/dirt. i would have thought the lsd would have transferred the power to the wheel with traction (the one on the tar) and i would have taken off normally with no spinning??? or is that what a vicious (sp) LSD does? what the hell is a vicious LSD while we are on the topic of them?
