1 AYC Bar
Ok so I have been doing a little research into a compatible rear diffs for my Galant (AYC Diff). Basically I am aiming to run some decent power about 330awkw/450awhp is my goal. I am currently waiting for parts for my brake upgrade then the next step will be to upgrade to a stronger diff before my current one gives up and further power mods continue.
So with the research I have done so far I have come up with a few diffs that are possible. I am unsure on how accurate these are but here is my findings..
EVO X Rear Diff
Details - (AYC + Factory Fitted Helical LSD) with more solid casing
Apparent modifications to fit - Larger drive shaft requires some machining internally to fit into vr4, Subframe requires slight modifications
Evo 8-9 S-AYC Diff
Details – Upgrade/stronger than standard AYC setup
Apparent Modifications to fit - The front brackets, tailshaft bolts, YAW lines all bolt in, the driveshafts slot in. Requires 10mm spacers on the rear mounts. Requires 4x4cm section cut out on the rear subframe for the YAW filler plug near the original filler hole. And there is a little 12mm allowance cast into the Evo diff casing that needs to be cut off to not foul on the VR4 subframe.
Evo RS Diff
Details – LSD mechanical plate type
Apparent Modifications to fit - RS Diff install kit for evo 5-9 with 10mm spacers for rear mounts and non-AYC axels.
ST-R or type V diff
Details – Open centre, non-AYC as Standard
Apparent Modifications to fit – Remove AYC system and directly bolt in place with non-AYC axels .
Upgrades – RS LSD cartridge bolts into diff housing
Diamontae/Magna AWD Diff
Details – LSD mechanical plate type, the same as the EVO VI RS
Apparent Modifications to fit - Requires 10mm spacers on the rear Diff mounts similar/same as installing an S-AYC Diff.
**UPDATE** I fitted a AWD Magna rear diff and Axels to my Galant 2 weeks ago now and is going great so far. Only required 10mm spacing on the rear mounts of the diff and everything else bolts up.**UPDATE**
Can anyone elaborate or correct anything I have above? Also any recommendations to what will more then likely handle my goal power level?
There is a few threads on rear Diffs but nothing all together so for ease of use I thought I would combine them all into 1
Also if anyone knows of stronger alternatives for Transfer Case etc. please add to it
