Throttle body

A question for those in the know
A mate needs a replacement throttle body for a 1zz 134bhp Elise, fly by wire
He says the motor keeps on sticking or failing
Can’t seem to find one second hand
BUT Gav has one or two from 2zz
Are they the same??

Could you tell from the part nos on Deroure?

Thanks 661
Don’t know why I did not think of that.
