LSD front and rear

 

Front:

 

Rear: (will need to find some CV cups for the rear.... or make some)

[evopwr]

I like the part where you said "OR MAKE SOME"

 

=)

Fuel tank design: 

 

Using stock fuel level sending unit and pump cradle. Pressure tested with no issues...

 

 

8mm plate to hold the sending units down

that looks epic! Is that all ALU?

yeah bro! 5056 alloy sheets.. it was an off the shelf tank I had to mod cause it was well.. shit.... ahahah ...

PS I love the pressure testing rig! Is that a BOV?

ahahah yeah bro, the old turbo smart big blue and gold piston BOV...

That's my old bov^^. Glad it's gone to good use!

Jayrome, it's a mechanical rear LSD, so normal rear CV cups will fit it.

You have a viscous front LSD. That's the LSD that you need the special longer CV cup for. You will also need a front diff crownwheel to suit the viscous centre, plus longer LSD bolts.

 

What rear diff ratio will you be running? 3.545 (GSR/VR4) or 3.909 (EVO I-III / EVO GVR4)? 

Because the 58-tooth viscous front diff crownwheel that you need for the 3.545 rear diff ratio is rare as (off a GSR RS).

The EVO I-III used viscous front diff crownwheels.

BUT, EVO I-II had 64 teeth to use with a 1.09 transfer case ratio and 3.909 rear diff ratio.

EVO III had 63 teeth to use with a 1.074 transfer case ratio to get the 3.909 rear diff ratio.

Just making sure you've got all that sorted

Ahh cheers for that, i'm running 3.545 VR4 

 

Front lsd I have the CV cups to match (this LSD was previously in my FWD box), crown wheel I will have to machine to make fit (unless the FWD box crown wheel fits the VR4 box?)

 

Rear lsd though, the CV cups I have here from a VR4 3 bolt, are to small. So i'll have to find to figure out what cups it takes... 

 

Will have to research more on the matter shortly after i finish the Fuel tank install and finish welding the body work..... 

 

 

Cheers for heads up!

Wouldnt the rear need a 4-bolt GVR4 CV cup? Might be same as a normal GSR/EVO anyway. Bazeng, BrisVR4 and some other GVR4 gurus should know.  Im not too clued up about the rear diffs on the GVR4's.

[evopwr]

 

 

What? Robs NOT clued up on something NON Gearbox/diff related? ARE YOU FEELING OK!!!!?

[JayRome]

finally got some time to finish welding up the rear chassis... Now to rebuild the diff and put some new bushes in.... 

 

[croket]

coming along nicely mate , ive read the mechanical needs 4 bolt cups. Ive just picked one up also so will be good to see what we can use

[JayRome]

Coilover design... mix of JIC/Tein/Pedders/HKS suspension pars....

 

[ted]

Love this car man!! so damn cool!!!!

[GSRSOL]

Nice work Jay; did i read somewhere youre looking for new wheels?

damn didn't realize someone commented....... got something lying around?? in the sizing of 17X10-11??

[JayRome]

So I have been bed ridden for 3 weeks, slowly getting back into the swing of things.....

 

Parts for rear end rebuild.. 

 

RDA looks to have merged a few of there brake disc's together old/new series 4/5 stud.

 

Handbrake finally set up

 

Rear end finally finished, LSD and 26mm sway bar installed, new carrier bearings with alloy bushings

 

3" full tucked front pipe

 

Need to make rear drive shafts, a few parts have to be machined to sit properly

 

Rear wheel clearance with 17X9.75 +25
