I searched and did not find references to a MAF conversion.  The shop that is setting up a MAFci intake and a shift kit for my ragtop (www.cp-e.com) is open to doing work on my '95 4Runner if there's need for something.  They can do about anything as it's a team of engineers that started the business.  For intake they said that they would try a MAF conversion.  On another car, they found a lot of hidden HP when the VAFM was replaced.  (about three times the average intake mod.)

1.  I see there are intakes out there but does anyone know of an existing MAF conversion kit? 

2.  Is there a common problem with any generation 4R that has not been addressed?  For instance, the Mazda 6s had lame engine mounts that started failing so CP-e just released a better one.

Put in your two cents and I'll pass on any recommendations.  Even if it's to say that we have all we need.  I love this truck but she's way underpowered. I wouldn't mind adding 20-30 HP to the wheels.
