I need to get a TC for my 98 Aristo before I do the single turbo conversion, because at 500hp is the limit. I am pretty sure that all the Lexus GS models have a 5 speed auto, and the 161 Aristo has a 4 speed. Does anyone out here know if the TT Supra which also has a 4 speed auto, TC will work on the Aristo tranny?

 

Aristo...not sure on this one...wish i could help out...did you check with japan side?

 

I know Revolfe S.A. makes TC for 2JZ-161 (V300). The retail price is 280000 yens. The stall speed is raised by additional 500 rpm.

Here is their website: www.revolfe.com

Good luck.
