Oh the lols

only do the Getrag if you do the 3.545 diffs as well, 1st gear in my 34 is now and always was useless even when it was a 2.6 with -7s, so add 4.11s to that and you may as well stay with the 5 speed as you won't use first with the Getrag

I can't wait to see the difference between 4.11s and 3.545s with the two identical OS88s once put side by side :D

I plan on being there for that event! :D

actually the Getrag is heavier then the 5 speeder so the advantage is on my side there by a couple of kgs

I'm hoping the longer first will get me off the line better and with the shift cut setup my ET should improve but doubtful my MPH will increase much, car is just to heavy :(

Needs more powahs

Ok well I've decided on the box I want and it's a ppg helical dog as like you piggaz highway driving with a 5th straight cut would do my head in. But would I have the same problem as with the os box regarding the taller gears that the ppg comes with? Sorry my set up is a an unopened rb26 which I'm about to put hks gtss turbos in..

If you are only going to run GT-SSs and no more, source a Getrag and 3.545 diff gears, much nicer to drive and plenty strong enough for the power a 2.6 with GT-SSs can put out

I will stroke the engine eventually and put bigger turbo's so will the getrag still be they way to go will be looking at 400+ at the wheels. but for know I will be driving it with the gtss and definitely need to do something about the gearbox as I have a few gears crunching

You know you can rebuild the box with new syncros for 1100-1200 bucks inc labour

Yeh but if I pull it out I would like to make it stronger. . The car does get used a lot for motorsport especially hillclimbs some 1/4 runs and the occasional track day ..

    • Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.
    • Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
    • To drain the Intake Heat Exchanger, there is a crappy drain plug in front of the driver's side front tyre: You should use the largest headed phillips screwdriver you had, and in my case I needed vice grips on the hose above as the plug was tight (tighter than it needed to be, since it has an o-ring seal).  After you have a tray down and open the drain, open the intake heat exchanger reservoir cap (drivers side one) and you should get a couple of litres of coolant To get to the radiator, you need to remove the plastic engine undertray. It is held on with a series of 10mm headed bolts and some clips. For the radiator, there is another type of crappy drain (kind of like a plastic banjo bolt) and you should attach a length of hose to direct the stream of coolant per this pic (otherwise the coolant hits the rad support and goes everywhere). The drain is on the rear of the radiator on the driver's side and a bit hard to find. Put a big tray or bucket down (5l won't be enough) and slowly unscrew the fitting by hand. You only want to remove it far enough for coolant to flow, it you unscrew it right out the whole fitting and direction pipe will come off and you will get a coolant bath (yum!). Undo the radiator reservoir cap and it should empty about 8l
    • So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You also need to drain the intake heat exchanger to remove the radiator so you will need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. 2 other tools that really help dealing with coolant lines and spring clamps are Bent Needle Nose pliers Hose pliers Between them they will reduce the frustration (and injury) potential by about 1000% Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic
    • If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.
