The 'ol single spinner ain't gonna be fun much longer as I start to add a bit of power. I haven't hit the track in the 335 but I did a few in the 330 and even with a lot less power the need for an LSD was there.

I'm throwing around some options, all of which are out of my price range atm (a fair few maintenance items to do first). Quaife is up there but there is a mob in the states that have a helical LSD shipped to me for around $1300 USD which seems reasonable.

A few guys are going 8.8" ford but I don't want to have to deal with modified housings or shafts or anything. Makes life difficult in the future.

Ultimately I'd love a BMW LSD that would just be a straight swap but they rarely come up.

Do I need to get these installed with some kind of specialist diff mob? Its definitely not something I'd try on my own.

Thanks guys.

There's a guy in NSW that specializes in BMW Diffs, 'Kurtis Aroney' supposedly.

There's also Difflab, who are in QLD and seem to know their modern BMW Diffs. Maybe someone in the local timezone that you can speak to :D

You can install a complete diff by yourself - you'll need a 50mm open end spanner to undo (and redo) the nut holding the driveshaft to the diff. Some of the underfloor insulation needs to come out to get access, but I've done it (on a 335i) on jackstands in my garage.

Oh, I meant more about the internals if I was going to put a quaife in or similar.

Thanks for this, I'll reach out and get some figures. I do think its going to be damn pricey though.

I was going to add a line about not trying to change internals but decided that was too obvious🙂 I wouldn't do it - the setup of a diff is a pretty specialist area.

Yep cool, it definitely looks scary on Youtube :D

    • Dear folks My family members have 4 different cars : Triton 2015 and Corolla 2011 and Mazda3 2012 and Hyundai Elantra 2014 Looking to buy engine oil funnel spill free What I found are are below  https://www.amazon.com/gp/aw/d/B0BBTTJNKX?ref=ppx_pt2_mob_b_prod_image&th=1 https://www.ebay.com.au/itm/145553221359?srsltid=AfmBOoqYBU6Ptw0LU_bAp_k67U3qkF97HHvePkA7iHZw8vUmiwoIRaRr https://www.amazon.com/gp/product/B09X23TCS5?th=1 Is there a funnel with attachment that fits most cars ? Don't mind to spend for a decent quality  Thx  
    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
