just fitted the 1jzgte to my ma70 supra. Started her up and we have an idle problem, at 2000 - 2500 rpm. Now we suspect its the ISCV as there is no clicking when car is turned off. We also disconected the rear air hose and blocked it, and revs dropped to 800rpm. Therefore the ISCV is stuck open. Tried spraying cleaner in it but made no difference. Got another ISCV off a mate but that was worse than mine, been sitting around in a shed for ages.
