    Eh yeah kind of. It increases the torque to the wheels, but not the top end power. Mine is definitely faster on an autocross course digging out of corners with the 3.38, but I'm shifting all the time. I'm dialing it back to a 3.23 this year so I still have 5% more torque over the 3.07 but it's not so aggressive. The torque bump is awesome!

    Where are you getting a 3.23 from? The ol' Bokchoy says the only E46s that had them were 325Xis

    Also has a finned cover and ball bearings on the output shafts instead of needle bearings (minor upgrades from the e46)

    I agree for track use 3.07 is way too long, 3.46-3.38 will be great, 3.23 too.

    ==============UPDATE==============


    Had to take time our from my project of gaining more horsepower as it turns out my engine has CO, probably the head gasket has burnt and gasses get into the water system thus the pressure increases into the system and the hoses are about to explode the radiator cap lets the excessive pressure but the water also gets out as the gasses raise the water level. The funny thing is that it only happens when i am racing, on normal driving conditions the hoses are fine. It should be a small crack in the gasket.

    I have already bought the Victor Reinz cylinder head cover gasket, rubber washers and head gasket. I am waiting on my mechanic to start the engine disassembly.
    There are 3 possibilities of what causes the gasses to travel into the water system:

    1. Burnt head gasket thus gasses get into the water system.
    2. Worn bolts that hold the cylinder head thus it cannot hold the pressure when revving up to 7000 rpm and gasses get out.
    3. Crack in the Cylinder head and gasses get in the water system.

    There is a possibility that all these 3 symptoms might be simultaneously :D
    After the disassembly i will take the cylinder head to the workshop where i will machine test the cylinder head for pressure and possible cracks, if everything's fine i will straighten (grind) on the machine for perfect surface and assemble the engine providing that the head bolts are fine, if bolts cannot be screwed because the threat on the block is useless i will get the help of a turner and install bigger bolts 11mm probably.

    Probably i will start the engine disassembly at 10.01.2020 i will post the details. After the assembly i will dyno the car as i haven't seen the gains from the ecu tune, afterwards i am planning on installing the regrinded intake cam, lift 10.2 and duration 262. I know it looks like swiss cheese but the holes don't cause a problem, a friend of mine has installed them everything's fine, he hasn't tested the performance yet. I also think of regrinding the exhaust cam to a lift of 9.7 as N52 engine all have that lift and it should work fine.

    I'm assuming it's this upgraded DISA by G.A.S. https://germanautosolutions.com/stor...sa-gold-valve/

    I used this one and it was fine. Might be a little cheaper for you over there.

    Good luck with the rebuild!
