S14 Blacktop SR20DET MAF compatibility

[treken2t87]

I am planning on driving from Indianapolis, IN to Fairfield, OH to pick up an S14 blacktop sr20det from Zerolift tomorrow. I was told the original price is $2,350 for the motor, tranny, ecu, etc (basically everything besides FMIC, tubing, and whatnot).
The motorset I'm interested in is actually missing the MAF, which bugs me a little (price is reduced to $2,250 b/c of missing MAF)
. I have searched and searched and there are so many different opinions on what will and wont work to replace the stock MAF (z32, q45, ka sohc...) The interesting thing is I e-mailed Jspec and will quote this:

honestly you are screwed, s14 sr comes with 2 different maf, and all
maf/ecu/harness has to be matching or else it won't work.
it's the reason why we said on our FAQ not to buy just engine and tranny alone.

Is it true that only a stock s14 sr20det MAF will work with stock ECU and tuning??? I really need this answered, please help!
