    VCU Questions

    Seeing as LSD's are around $1000, I was thinking about welding my VCU......With my 600hp goal. Im very sure I will keep my T70 if I dont have to spend 2k on LSD's .

    Will this make my trans stronger?
    Has anyone done it and is there anything you dont like about it?
    Know of any good write ups?
    Anyone want to sell me a junk VCU so I dont have to ruin my good one?
    Im sure theres a way to weld the rear diff...I just dont know how to go about it. Any write ups on that?

    Thanks a bunch

    It doesn't make it stronger, it just eliminates front to rear wheel slip. Enough wheel slip can make your center diff frag, so this can help prevent that. Eliminating the VCU by welding the center diff makes it harder to park your car, and can make it chirp, or squirm when taking tight bends.

    Welding the rear diff makes your car even more of a bitch to park, and it will squirm and chirp tires in bends as well.

    Im not to worried about parking because there is almost no parallel parking spots around here. And I dont mind the chirping and wearing .

    Ok so would I still have to get a front LSD or is that weldable also? Or are ours already LSD since we have ABS? Could it handle 600awhp?

    A fully welded drivetrain would be... really silly on the street.

    Easily. Ray is running a stock VCU, IIRC.

    Very nicely put.

    There is no need to weld all 3, i am making 500 wtq on completely stock drivetrain with no bracing. How you drive the car is more important than how strong it is. Like i have said in many other threads, our shop evo makes 800 whp has made 100's and 100's of passes on the track, street, and dyno and never broken a T-case yet. We have a customer who has had 2 evos with decent bolt ons, his current evo makes 400 wheel and in about 5 passes at the track has broken 3 transfer cases because he cumps the clutch.

    If anything weld the center diff, and maybe the front, if you do this maje sure you leave power steering, because it gets real hard to turn.

    -Ricer Evo 8: 8.75 @ 166 Best MPH of 167. Quickest 4G63 Powered Evo in The US!!!
    -Chris Cessna's Stock short block Evo 8: 9.76@150 Worlds Fastest Stock Motor Evo 8 and First Stock Block In The 9's!
    -Shawna's DD Evo 8: 9.97@143.88 Best MPH of 145 Full leather interior, A/C, navigation, stock brakes, cruisin 9's in style
    -Cory's Stock 7 bolt talon: 10.3@136 No crank walk here...
    -STM Stock turbo/motor Stealth RT: 10.95@127 Worlds Quyickest/Fastest and most powerful Stock turbo/ motor 3S
    -James STM built Pump gas Evo8 stock motor: 10.2@137 Stock long block, and only on pump gas!
    -Mike Faggiano Evo3 16g stock motor 1g 11.0@124 just a 16g knockin on 10's door.
    And the list goes on...

    i wouldn't weld anything. even with vcu replacements, it still makes more sense to weld the planetaries or trade with someone who has a toasted vcu.
