Smal progress Engine and gerbox are in place with help of a close frend i cant valk normal yet and might neead new surgery....

But i hawe made som smal progress with the electrical system added Boost valve, boost temp out of turbo and idler motor.

The gerbox is a tight fit since im still on th auto gerbox tunnel.

I hawe made a adapter from the Bmw 3bolt hardy to toyota 4bolt prop but i mad it in steel and dont like that its hevy so i considder redoing it in alu....

Next project is to make a new rear gerbox mount and integrate a sensor on the hub that reads from a abs ring so i can make a convension in the maxxecu so my speedo works

Great work mate. Looking at your work and the effort involved just made me decide not to work on my Supra again myself. Everything you have done looks too difficult for me to even attempt. I shall stick with stock unmodified supra :D

Well done.

wow very nice build, im from Canada and have rhd supra as well, and i would like to convert it to LHD. Some quick questions to help clear up the bluriness for me

 

-what did you do with the fuse fox that was located in the interior?

 

-what did you do with the original JDM interior harness that plugs everything in, like odometer, ect..

 

-can the original jdm harness be used to power everything on the driver side? without modifiying the harness ?

 

-what did you do with the trunk and gas cap release buttons? do they just comfortably reach on the lhd side? Do they bolt right into the floor oem, or did you have to drill new holes in the floor boards?

 

-also what RHD parts can be used over to the LHD side? Pedal assembly? Ecu?

the cabels and leaver is discontinued from toyota so im still looking for used ones the floor has space for the leaver but not the carpet

 

 

-also what RHD parts can be used over to the LHD side? Pedal assembly? Ecu?

steering collum can be used but not the pedals

 

best way is to get a crashed car from copart ... and take evrything from.
