I'm with 18psi on this. It would take about an hour to swap injectors, unplug one ECU and plug in the other, and put your factory MAF and snorkel back on. Seriously, an hour. And you would need to swap back to stock injectors for your smog test anyway if you were using an FMU. So 30 minutes.

Are you afraid of ECUs? I was. But not now. If I had known it was this easy I would have done it a bit sooner.

I just did this few months back. I'm running an NB so i have to open up the intake manifold to pull the injectors... injectors took me about an hr (1st time i've done them my self), maf took me about 5 mins and the ecu another 10 mins to swap.

Giving BEGI a call will probably be very helpful. I'm personally planning/trying to keep my OBD2 compliance with a MS1 running in parallel to the stock computer. I *think* I can make it work if I get a reasonable tune, but I've been too busy to really work on the car lately and get a few necessary things done on it.

What is the limitation on the former vs the latter?

If you answer these questions honestly and correctly, you'll kick yourself in the foot for thinking its "more expensive".
I can kinda sorta understand the whole "obd2 compliance" thing, and even then I'd much rather just swap to stock ecu/injectors for the annual or bi-annual test. Takes about an hour working slowly.
I bought everything I have used except for the wideband.

t25, header, boost box, bov, fmu and intercooler for 750
305cc injectors 40
190hp 90
rx7 afm 45
wideband 130

But on that note if i hadnt been able to find the complete set for 750 to start with I prob would have went a different route.

But seriously,
I like how you're trying to be spoon fed without coming off like a lazy noob.
Throw it on there, plug in a wideband, and start adjusting.
