Hi Terry,
What is involved in converting a ST246 to manual transmission?
Thanks

Dont think it has ever been done so who knows.  Obviously need to install a clutch pedal.  May need a custom tail shaft, not sure :)  You'd have to buy one and try it.

theres a guy on toymods that has done a manual conv in a caldina..
 
think you need all the manual bits from the earlier model

sorry, dont know. never done a 24 model. if its the same as earlier 215, then easy enough.
note, the GT4 stuff wont suit!!!

Since there were never any manual ST246's (even the non turbo models), such a conversion would require a lot of attention to get right.

fitting a manaul into a 215 is all plug and play.
i need a 246 here to investigate that model.
my guess is it will not be simple as the wiring/electronics will be different for sure
mechanics wont be a big hassle
the auto tailshaft is different in 215, so i assume will also be in 246. custom sharfts are easy
shifter/console can probably come from the lower spec models.  

There's no lower spec MT shifter/console from that shape/interior, so would need to be a custom.

i swapped st246 from AT to Manual transmission. it's simply.
you need: manual gearbox from st-205 celica or st-215 caldina, flywheel, clutch pedal, clutch cylinder,
gear shifter et.c. I live in moscow/russia, here's some caldinas that was swapped from automatic to mechanical transmission

i dont think there is anything more to say on this.

Whoa awesome gcat! Drives much better in manual?
