Daninplymouth 61 Report post Posted January 29, 2020 Hi, just seeing if there is any interest in this. Part will be removed at the start of March, only going back to standard as I’m going turbo. Has been fitted for about 8months so only done a few thousand miles. Think it’s a great mod if staying NA £300 posted Share this post Link to post Share on other sites

Just out of curiosity what did you do about the speedo reconfiguration? As I assume it put your speedo out of wack? Also whats your top speed now? I assume the diff has improved the acceleration at the expense of top speed and fuel economy? Would be interested to know what your 70mph cruising RPM is now.

No speedo is the same as stock as the speed sensor is taken from the wheels. dont know about top speed but it has to be about 130or so if not more. On my 18” wheels my speedo is pretty accurate and 74mph is around 3500 i actually haven’t noticed much change in mpg day to day use I tend to sit a gear higher than standard and on a run can still get over 40 Share this post Link to post Share on other sites
kaisersalsek 47 Report post Posted March 6, 2020 As above on the speedo - that stays the same. Top speed - don't know. Can't remember what the rpm at 70 was before and don't remember what it is now either lol Sorry for being completley unhelpful lol 1 Leeky reacted to this Share this post Link to post Share on other sites
Leeky 84 Report post Posted March 6, 2020 Cheers guys. Sorry for hijacking the thread. Just that I saw kaisersalsek had this diff on an auto and I was pondering this as a mod for my auto. Share this post Link to post Share on other sites
kaisersalsek 47 Report post Posted March 6, 2020 I would really recommend it at least for road use - I got mine at the same time as the Tuning Developments NA package and lightweight pullies, really made a massive difference in terms of acceleration. 1 Burtie178 reacted to this Share this post Link to post Share on other sites
Leeky 84 Report post Posted March 6, 2020 Yeah mine is purely a track car so the only road miles it see are between home and track. So fuel economy isn't an issue for me; just curious. The top speed of a stock auto 86 is 130 according to Toyota but I don't know if thats a gearing limit or a power based limit. Assuming its a gearing limit then with a shorter final drive the top speed may drop to something like 120 but I dont know for sure. Share this post Link to post Share on other sites

No that top speed is the max the car can pull due to its power, gearing wise I think it is something like 205mph if you could redline it so you may actually gain top speed on an auto. i can’t think of many tracks where a Na gt86 can get close to its top speed but could be wrong Share this post Link to post Share on other sites

Thanks for the info. That makes total sense now as the auto has longer gearing than the manual. Share this post Link to post Share on other sites
