i have a 93 sc300 with a 1j.i recently did a w58 to r154 swap. i got a unsprung 6 puck act clutch with a extreme pressure plate and a lightened flywheel. and everytime i start pressing the clutch in the car drops in rpms and when it is fully in the car just dies.

Does the car run fine at idle? Is your throttle cable too tight?

it idles fine. its just when i press in the clutch it dies and i cant figure out what causes it to do it. is there some kind of sensor on the trans itself that needs plugged in?

is it bogging down and dying? Are you sure the adjustments are correct and the clutch is engaging/disengaging properly?

sounds like crankwalk the extreme pressure plate is to heavy esp for a 1jz .. heres what you do get a friend to press the clutch for you while engine is running , you stay up front and keep a eye on your crank pulley and see if its moving in and out when he/she presses clutch.. if its moving in and out its moving past crank position sensor hence why it shuts off

I was going to say crankwalk too. I hope its not for your sake.

let hope its not... but what if it is? new block, new crank? what are the repercussions?

I just hope it's not the crankwalk, it's not fun you will end up spending money on a new block and some others parts like oil pump, i will even replace the head because if you distroy the thrust washers it's done.
R154 and HD Single Clutch don't go together....
