Suitable manual box for 1uz

[Newoldschool]

I have recently acquired a complete 1uz engine with an automatic box and want to convert it to a manual is there any suitable straight swop to a manual or it there any manual gearbox's that could be modified to fit,full fabrication of bell housings not a problem since i work in an industrial gearbox repair and manufacture company

[andrew_mx83]

depending in the induction of the uz

n/a = w58
f/i = r154



there is no "straight swap" that i know of

[Newoldschool]

thank you for the info i think i'll take the r154 keeping the option of forced induction at a later stage

or if you want to do it yourself, ed sells the CAD designs on egay

thanks but i have had a look and will write my own program ,what is the max rating on the r154? i dont want any surprises when the time comes

That question all comes down to opinion really, I've seen plenty of 2jz's with over 500rwhp that have r154's and they seem to be fine, some have as much as 700rwhp. Depends on how you treat the box, Tyre size, how many clutch drops etc,

I hope this helps

it helps but maybe i should invest in some custom gears and drive shaft whats your opnion

[td42gq]

what sort of hp are you chasing? If it's 500hp or less you should be fine.

[pandaah]

mate.. why dont you go and look at a 6 speed getrag from the jza80 supra... if your gunna custom fit it yourself then you shouldnt realy have a problem, and the 6 speed getrag is much stronger again..

there used in obviously the supra, but also maserati 3200gt's which are v8 twin turbo..

I would also be looking a the tremec gearboxes as well. There is a large range of ratios and differeing strengths. The R154 is good but getting a bit long in the tooth. Use the 1UZ bellhousing and make an adaptor to the gearbox of choice and then just use a hydraulic throw out bearing.

im looking for bout 400whp n/a and maybe add twin vortech's for 750-800 on 102 im looking to keep it streetble but home on a strip and the track maybe sideways for kicks i looked into the jza80 box and there seems to be 2 different versions of it the v160 and v161 but seems i cant find it over here i'll have to look around a bit more and i think the owners wont be easily convinced to part with them

[JustenGT8]

Skip R154 and go straight to Tremec....my pick for bullet proof is the TKO600 but a T56 6 speed is still decent choice...the TR6060 would be nice once the prices start coming down.

[pandaah]

prity sure the T56 box is used in the SS commodores... which are actually a really good gearbox, and from the ones ive seen, already come with a hydrolic throwout bearing, but ud wanna give the transmission tunnel some clearence cos the bleeder is at the top of the bellhousing

[Newoldschool]

i've heard of a grinding issue with the tremec box's in cold conditions,

[JustenGT8]

Mine has been fine and shifts a shitload nicer than a R154 Plenty of frosty morning here in Canberra

[Newoldschool]

thanks for all your help i might swing round if i run into any issues once again thanks for all your help

[pandaah]

what oil do you use in your tremec justen?... the SS manuals recommend dextron 3 ATF fluid but ive always wondered if say 75w80 synthetic would make them feel abit nicer

that is such a whacko sentence im not sure where to begin?

exactly what do want to achieve?? build 500bhp NA engine, and THEN whack twin SC onto it? common, reality check? happy to help with some ideas if youre interested, but i think you might need to tighten your focus a little?

as for the CAD designs, isnt $20 a hell cheap way to avoid hours and hours of measuring and designing? why reinvent the wheel?

cheers

I just use the ATF as Tremec recommend...i ran ATF in my W58 and in the GTFour GrpA as well.

The shifts are slick but 'mechanical' in feel if that makes sense?

What sort of ATF Justen?
