Toyota MAFs

Does anyone know of a larger mass airflow sensor available for 
93-on Toyotas, namely the Supra? 
	What most Supra owners do is replace the MAF with a device from 
HKS called a VPC (vein pressure converter) when upgrading to a larger 
turbo, etc.,hanging the fuel system to a speed-density system. It's 
basically a MAP sensor with a black box that sends the proper signal to 
the ECU. The box contains several adjustment knobs for fuel pulse, 
gain, and idle mixture. Only problem with this device is the constant 
need to readjust the VPC when there is a large change in air temperature 
and humidity.
	If there is no available upgraded MAFs, how hard would it be to 
use MAF from a Mustang? A friend of mine has the chance of getting a 
larger aftermarket Mustang MAF that has the proper interface required to 
work with his 95 Eagle Talon TSi, would the work required to do the same 
for a Toyota run a lot more than $1000 (usuall price for a VPC)?
