adam1983 Posted February 24, 2015 Share Posted February 24, 2015 Not sure if this is a daft question but was on my mind. Apart from the 4 speed auto box are there any other auto boxes that are compatible? If not is it possible to make a different one fit? For example would it be possible to fit a 6 or 7 speed box from a similar powered car? Link to comment Share on other sites More sharing options...
chazuk Posted February 24, 2015 Share Posted February 24, 2015 Be allot of work not just mechanical I would of thought you would need a standalone ecu as well to control it, like anything custom the cost would probably be so high you could buy a brand new 6spd or a built auto box plus have re-sale value in the car.

adam1983 Posted February 24, 2015 Author Share Posted February 24, 2015 No doubt there would be probably big costs involved for the full project but just interested to know how straight forward it would actually be. I know boostlogic and titan do uprated auto boxes but I think that's just using the existing box but with better parts to make them stronger.

Hitbox Junkie Posted February 24, 2015 Share Posted February 24, 2015 Anything is possible with enough molla . I'd love a sequential box in a supra or a hurst shifter As said above possibly not worth doing and could cost as much as a 6 speed conversion.

adam1983 Posted February 24, 2015 Author Share Posted February 24, 2015 Would a sequential box add more gears? Would be interesting to know a rough idea on cost too as a 6 speed manual box is not exactly cheap these days Link to comment Share on other sites More sharing options...
MattP Posted February 24, 2015 Share Posted February 24, 2015 I'm sure 2bar tuning or SRD mated a 7 speed Lexus box to a supra with the aid of a syvecs a few years ago.. Link to comment Share on other sites More sharing options...
mellonman Posted February 24, 2015 Share Posted February 24, 2015 The drag racing boys use a TH400, So I bet there is a complete kit out there Link to comment Share on other sites More sharing options...
adam1983 Posted February 24, 2015 Author Share Posted February 24, 2015 Both of those sound like the sort of thing I was thinking about. Going to do a bit of research into how much work and cost is involved. Would be interesting to know what model the 7 speed Lexus box came from and how much power/torque it could handle. Do you know how many gears the TH400 has mellonman? Link to comment Share on other sites More sharing options...

Nodalmighty Posted February 24, 2015 Share Posted February 24, 2015 Do you know how many gears the TH400 has mellonman? 3 unless you fit a Gear Vendors gear splitter then it has 6. Link to comment Share on other sites More sharing options...
