David P Posted April 19, 2011 Share Posted April 19, 2011 Custom built by Driftmotion U.S. for N/A auto, this is the only one on the planet. Would require a thicker adaptor block to fit N/A MT5. Maybe fits Supra with R154 conversion, but no-one has managed to measured one yet? The OE two piece steel prop weighs 24lbs, this lightweight one-piece is only 14lbs. Reduction in rotational mass liberates circa + 5 bhp @ wheels and + 1 mpg. My plan was to include this propshaft upgrade in the Hybrid transmission build, yet the engineering required to modify the tailshaft proved too expensive. This has only been on the car a short time and has proven a perfect fit and well balanced. I had to wait 7 months for this to be made and will be sad to see it go. The improved connection between transmission and diff is quite noticable in a 'James May's nether region feeling' kind of way! I could re-engineer the front of this to include a sliding yoke and use it, but it is way too good an item to recycle. I would sooner sell it on for £110 less than I paid for it and put the money towards having another made. Asking price reduced to £275 plus £10 P&P for U.K. mainland.

David P Posted August 18, 2011 Author Share Posted August 18, 2011 This maybe fits R154 Supra installations. Provide the measurement from face of output shaft to face of diff flange without donut for me to confirm. Link to comment Share on other sites More sharing options...

spider2123 Posted September 18, 2011 Share Posted September 18, 2011 Sorry mate really wanted this, the autobox I have now has a fixed flange - Link to comment Share on other sites More sharing options...
David P Posted September 18, 2011 Author Share Posted September 18, 2011 It won't fit a T.T. auto or 6MT without the addition of a slip yoke at the front, because they both have flanges on gear-box tail-shaft. 2" too short or too long, can't remember for an MT5, would require 2" spacer adaptor at the rear. Fits an N/A auto perfectly. Could prove to fit a Supra with a 2JZA and/or 1UZFE R154 conversion, if anyone every gets around to measuring the length of prop required.

David P Posted May 18, 2012 Author Share Posted May 18, 2012 I have discovered that it's not possible to have a flange/sliding-yoke fitted to the front of this so it's of no longer of use to me. Asking price reduced by £50 to £275. Link to comment Share on other sites More sharing options...
