Just use the gears out of the Skyline/Pintara 3.9-4.11. You'll be looking around $250+ for a complete diff from the wreckers. You'll find your 25 spline axles will be a weak link.

I Have A 9 Inch Housing I Brought Of Ebay For It Its All Set With Mounts Etc, But Its To Short Must Of Come Out Of A Mini Tubed Corts, Im Not Sure If I Should Spend The Money Getting That Extented, Axles Made Or Get The Stantard Diff Done, Ive Already Had The Standard Axles Restudded To 5,to Match The Front Brake Upgrade.any Ideas Guys.

just use the standard diff as you'll save hp and weight. Get a 4 pin LSD from a Falcon and use 28 spline MOSER axles. Or make it "unbreakable" and use 31 spline axles and fullspool. I'm looking into making a diff housing brace for the Borg Warner just incase the 302 ever makes the hp I want. Or mini tub the corty and fit the 9". Its not hard, I did mine start to finish in one day.

A few pics before, during and after mini tubbing

2nd and 3rd should be around the other way

td302 you saying the skyline gears fit straight into a b.w

TD302 · 08-06-2004, 01:57

yep crown and pinion fit straight in. Just the lsd or what ever fitted wont fit because their 28 spline and the cortinas are 25.

cheers guys, so if was to use my lsd center put on the gears from the skyline i couldnt use my axles id have to change to 28, did you have some made to suit the corts, [/u]sorry to be a pain the butt guys.[u]

If the LSD is fitted in your Cortina now then you can use it . If it's an LSD out of the skyline then no, only if you get some 28 spline axles. Yes I got custom MOSER billets($1150inc GST) made to match the standard size as I wasn't going to shorten the diff. I just made a custom set of 8" wheels to fit. So from side on they don't look any different then a set of 6's. Not a pain in the butt mate. You can only learn by asking questions.

Hey Boosted

Guess this is what this forum's all about we come here when we need info...just so you know I am still in the process of deciding what diff to get so I am about 2-3 months off asking the same question myself...thanks for your input and questions.

TD302 for some reason the attached thumbnails aren't coming up on my lappy as I am real interested in having a look, has it got something to do with a setting some where?

Cheers
