    Torsen into the LS400 UCF10 / UCF20

    :thinkerg: would that be to compensate for a heavily lowered geometry? NVH is noise-vibration-harshness ... engineering term

    Torsen into the LS400 UCF10 / UCF20

    swapping out the mounts for harder polybush sway mounts will also make the sway bar effect come in sooner, taking up the slop of worn softer rubber bushes. I know you can do the whole car in poly, but sway mounts alone shouldnt have any NVH issues as a compromise.

    Torsen into the LS400 UCF10 / UCF20

    In the uk we have a special model MkIV ... DHP, I've bought one last weekend, transforms the drive, unbelievable more responsive, much quicker to turn in.. im blown away, more improvement than I expected. That acheives the turn in by a 1mm thicker rear anti roll bar.. SO out of interest...

    Torsen into the LS400 UCF10 / UCF20

    FastEgg., I'm in the same boat as you, I had LSD rwd motors and moved to an LS400 vvti, shame to see the VSC light everytime the wheel is past 2'oclock and the pedal is past a 1/4. I have also been researching this and a Torsen T1 from a mk4 supra TT AT or NA should fit.. 200mm crown ring...

    Improving shift on Auto's. two types of accumulator mod.

    I really am new to the specifics of auto's but I am drawing on knowledge from other fields. With that in mind, a stupid question.. the later 5speed ECT, uses solenoids to control shift patterns. Do they still have accumulators that can be 'shift kit'-ed or do the solenoids do the work? At a...

    Improving shift on Auto's. two types of accumulator mod.

    On here i have heard of shift kits and read a description of fitting a washer under the accumulator spring. Another method i have found from a Volvo site was to fit a bar insert inside the spring, barely a 1/4" shorter than the spring itself. Both methods reduce the time it takes the...

    safe power for LS400 vvti 5sp autobox?

    Well if i work to 500whp.. can always redo the project later if needs be and tune/changeout for higher. I have tried to have a good read around to answer my own questions, but I think all I have acheived is confusion. Seems a lot of my issues come from this being a VVTi with a later 5peed...

    safe power for LS400 vvti 5sp autobox?

    I think my conufsion is that there might be a 350 and a 650 gearbox. I do have a 5 speed box thats for sure. I hope to get to 500WHP sorry for the confusion there. A charger like that would be a little wasted otherwise. Thanks for all your pointers SPF (y)

    safe power for LS400 vvti 5sp autobox?

    Okay I'm with you now. The early rods do look a lot stronger and according to whats written about them will be plenty strong enough for my prospective whp. There is a post here about upgraded billet sprag clutches for 650 gearbox, is that the box i am likely to have in my LS. Unlike the owner...

    safe power for LS400 vvti 5sp autobox?

    the later model has vvti which makes it quite a bit more powerful.. when supercharging, does the VVTi advantage matter less? or would it be well worth using a '93 block and a VVTi head with a SC. cheaper obviously just to use a nice low mileage 1993 engine. I will head to the storage in a few...

    safe power for LS400 vvti 5sp autobox?

    I already have the charger, from a late model AMG Merc SL55, 20k miles IHI Japan twinscrew Lysholm unit, Has a waterpump built into the nose and a charge cooler unit strapped underneath. Can get to my garage and take a shot of it if it helps? its huge, really needs a 6l engine to use it, but I...

    safe power for LS400 vvti 5sp autobox?

    Its a 1998 vvti Ls400, I want to charge it, but keep automatic tranny. I have a bike for grabbing at gears, just want the LS to be a smooth beast. It has the later 5 speed box, what kind of power can these take before destructing? I have the option to put 20psi boost into this 1uzfe-vvti so...
