Little help, R154 or W58

[Jake Breyck]

i would like some expernaced opionions on this.. im at the point in my project that i need to decide on the tranny i would like to use.

The motor is a 1uz twin turbo, i plan on having no more then 600hp
less then 400hp on a day to day setup.

the R145 can handle a little more power,
the W85 is lighter.

do you all think that the diffrence in power handeling is worth it, or should a good W58 handle my power goals.

btw this is going into an 86 corolla should be about 2000lbs.

Jake,
you WILL kill the W58 with a TT 1UZ - I've heard 300 - 350HP through those maximum, and if you're building a TT you owe it to yourself to over engineer it... I think there's only about 8 - 10kg difference in the weight anyway...

1uz with turbo will be make about 500 lbs even with 400 HP. so torqe will be huge. W58 will not hold that stress. I have cut off pics that both trannys (from service manual) and must say r154 have much beff internals. MUCH stronger. so only r154 or v160.

500 ftp/lbs and 400hp makes me smile. looks like ill be ordering up a R154 bellhousing soon. i guess i can search the site for who to order one from its been a wile sence i saw that info.

you will have problems with aftermarket bellhousing if you want use stock mk3 turbo clutch cause stock clutch use "pull" type clutch bearing . stock r154 clutch is pull type so slave clutch cylinder should be from back to front position.

All bellhousings I seen was for push type (slave clutch cylinder mount in front to back position).
