mossy74 Posted February 28, 2006 Share Posted February 28, 2006 I'm putting a 1uzfe into a 240z and was wondering what the best box is to use considering i can get a s/h r154 for $1300aud or a w58 for $500aud. Quote Link to comment Share on other sites More sharing options...
tannji Posted February 28, 2006 Share Posted February 28, 2006 I have been told that the w58 is the way to go, that the next better tranny would either be the 6 speed out of the Supra, or something even more pricy and less friendly to drive around town. Isnt the 154 a truck tranny? I think it is a little lighter duty than the w58, and unless specifically from an appropriate car, it would be geared wrong. The w58 should be good to around 350-400hp, as long as you dont hook up and are kind to it. What are your plans for the 1UZ-FE? NA, or turbo, ect... need some details! = ) There are one or two others here considering the swap, and I would do it if the 2RZ doesnt pan out for me.

mossy74 Posted February 28, 2006 Author Share Posted February 28, 2006 I thought the r154 was out of the turbo supra? By the way I don't plan on running anymore than 400rwhp. Quote Link to comment Share on other sites More sharing options...
Supra510 Posted February 28, 2006 Share Posted February 28, 2006 The R154 is the trans for the Turbo Supra (in the US at least), W58 is the non-turbo ntans. The W58 might last at that power level if you baby it, but it's more fragile than the R154. I don't know what clutch setup you're planning on, but the clutches for the R154 can hold quite a bit more torque than those for the W58 without having to resort to a 4 or 6 puck clutch. The R154 uses a pull type clutch not the more common push type. I have been running the W58 behind my 7m-gte up to a dyno verified 357 rwhp, but that was before the new turbo. My clutch can't hold more than 15 psi at a track day where you have multiple high speed runs within 20 minutes. I refuse to go with the race clutches so I bought an R154 (and flywheel, and driveshaft) so I can have a stronger trans and a stronger clutch.

Clifton Posted February 28, 2006 Share Posted February 28, 2006 There a few places in Australia that make belhousings for the 1UZ's and R154's. A stock R154 clutch will easliy hold 400 rwhp/tq. The R150/R151 are trucks boxes. Very few people break them. Quote Link to comment Share on other sites More sharing options...
tannji Posted February 28, 2006 Share Posted February 28, 2006 Thats good to know, I thought the Supras had a getrag tranny. Looks like some for searching is in my future... = ) Quote Link to comment Share on other sites More sharing options...
Clifton Posted March 1, 2006 Share Posted March 1, 2006 MKIV Supras do. MKIII's use the R154. Quote Link to comment Share on other sites More sharing options...
