Redline Hi-Performance gear oil.. opinions/comments

[amel666]

I've just finished surveying for gear oil for my gearbox swapping project. I'll be swapping on an evo 3 full-lock LSD box to my 4g93t GSR. The brands dat i looked up was:
- Torco SGO SAE 75w-90/ (synthetic) rm 105/Lit
- Torco RGO SAE 80W-90/80w-140 (synthetic) rm 60/Lit
- Motul 90pa LSD fluid (mineral) rm 108/Lit
- Motul GEAR FF-LSD TYPE 2 TOO Expensive +-rm145/Lit
- Redline Hi-perf SAE 75w-90 (synthetic) rm 60/Lit
- Redline Hi-perf SAE 75w-140 (synthetic) rm 60/Lit

I asked for opinions frm the vendors. I cum to a conclusion dat Besides d extremely xpensive Motul GEAR FF-LSD TYPE 2... Torco SGO SAE 75W90 is d best gearbox oil but too expensive (rm315/ 3 liters). Motul is good but mineral + also expensive. Leaving only the Torco RGO SAE 80W-90, Redline Hi-perf SAE 75w90 & SAE 75w140 as an affordable options-> rm60/lit.

First, i wanted to go wit Redline 75w-140... but d vendor advice me 140 viscosity is quite thick so it needs to be driven hard to warm up d fluid. So I made my decision to buy d Redline Hi-perf SAE 75w90 after reading its label hoping that d hypoid gear oil would perform well inside d LSD box (plus budget only +-rm200). :hmmmm: Besides dat, currenly i am using Redline LightWeight ShockProof in my GSR open-diff box and find it satisfying.

I also bought Torco's LSD friction modifier additive to b mixed wit redline fluid hoping it could reduce d chatter of d LSD.

Does anybody hav any experience using Redline Hi-perf SAE 75w-90 wit their full-lock lsd box or any of the fluids stated above?
Do u think d SAE 75w-90 is enuff or better swtch the fluid wit redline 75w-140 to protect d box in our Malaysian weather? :hmmmm2:
Thanx in advance

PS:
probably be changing d fluid after +-5/8k km. Depending on d driving conditions.

went back to ask whether can swap to 75w90ns, the dealer told me dat only Subaru uses them. Cant guarantee can use on evo 3 lsd box. So i left wit the 75w90.. hope it wont hurt my synchromesh.. :hmmmm:

Btw, anybody knows whether using gsr final drive in evo 3 box is smart thing to do or not? or better just use original evo 3 ratios on my est: +-300whp gsr...
Tomorrow going to swap gbox.

better use original evo3 gearbox ratio for 300hp... you will feel the respond...

evo3 box with gsr final drive.... good for hi speed & cruising.. off boost on gsr sure no power...

Thanx 4 d strait forward advise

So its best if use original evo3 ratios (FYI i'm using garret's gt2871.. but dont kno if its relevant or not to choosing the final drives..). Would i get enuf traction when starting frm grid line/idle? Would the 1st & 2nd gear be too short or just nice..
As I'm planning on using my daily driven 4 ocassional autocross & 400m sprint.

But personally, i feel like wanna try wit evo 3 ori ratios. Then i'll know how it performs. Plus less hassle coz no need to open my GSR box.
Hope i feel the engine respond & still hav reasonable top end speed.
