What is needed to convert speed density to a mass air set up?

I am looking to to convert my 88 gt convertible from speed density to mass air this winter. What exactly is needed to do this? I'm running a 70mm t/b. What size meter do I need? Since I'm doing this, if I change to 24lb injectors, should I go with a cobra ecu? Do I need a whole new harness? Need some details and advice. Thanks!

Correct me if I am wrong but I think you would need a 70mm MAF to go with your 70mm T/B. I mean you can only shove in as much air as the T/B will allow into the manifold. Does anyone else know? Would you also have to port your inlet to 70mm on your manifold to allow the use of a 70mm T/B an MAF Meter? I know you can buy a Speed Density to MAF conversion kit from Jegs online I think it's somewhere around $80 made by Granatelli. As far as a Cobra ECU goes it's around $550 and it comes with a 70mm MAF Meter and 24lb injectors, also from Jegs. Or you can get the FRPP MAF Conversion Kit which comes with an ECU, MAF Meter and electrical connections for around $550 I'm not sure of the size on the MAF Meter so you may have to ask. You may be able to find this stuff at a cheaper price but you'll have to research it.
