4age auto to manual conversion

[mikeymike]

I've decided that the auto just needs to go from my smallport red top ae92 fx-gt. I've got a ae92 gtz lsd box to go in. Just wondering a few things:

1. Do I have to run a 4agze clutch set up with the box? (I've already got a 4agze flywheel)

2. Will the auto shafts fit or will I have to change something there too?

3. Pretty sure I'll need manual gearbox mounts, but just checking that the auto ones won't fit?

Cheers,
Mike

Sell that box, and buy a C56. E51 ratios aren't really suited to a 4AGE

E51 gear ratios aren't that bad, its just the long 3rd gear you might struggle with.

Just looked up the speeds vs. rpm online. E51 has longer ratios (100.88kph @ 3000rpm), C56 (89.92kph @ 3000rpm). It's only a daily driver so this shouldn't be too much off a biggy?

Certainly you will need the correct driveshafts for the E series gearbox
You will need the correct mounts for the gearbox
You will need to use the correct clutch as the E series box has a bigger diameter input shaft

You will lose some power as there will be bigger losses through the gearbox
Also the gearbox weighs about 15 or 20kg more than the std C series manual gearbox

The ratios are way more suited to the extra mid/low end torque of the GZE engine

Your car will be slower with the E than the C box. My AW was 3 seconds quicker around the old Taupo track with the C box than the E box - it was the only change I made between race meets. As Kinloud has said, it's the extra weight of the gearbox, the internal components and the driveshafts that do it. Although the E series flywheel and clutch are lighter, they won't fit inside the C series box.

Thansk for that guys. Hmmm might have to sell it and look for a c56. Be cheaper and better in the long run.
