Old IHI BEGI kit (system 3)
Currently installing a beautiful used intercooled kit I bought for my 91.
It looks like an early Corky Bell IHI s3. This has been confirmed by Stephanie at BEGi by looking a pictures and appears to also be the same kit as the very early flyin miata kits.
Going to tune it with a used AEM standalone because the FMU and MSD freak me out a bit.
Anyone have experience with this kit?
Got any maps I could use as a starting point to save some dyno time?
Any tips, dos and dont's, advice on what to expect from the kit etc?
Also, is it worth the effort of swapping out the 1.8 injectors from my other car for the 1.6 injectors?
Bigger injectors are not in the cards right now unless I find a seriously killer deal on some.

Standalones are not magic - you can't just slap a turbo in with the stock injectors and expect it all to work.
Do you have a wideband?

I realize they are not magic . I had planned to keep boost down only to what my injectors could handle initially which I figured was about 6 psi.
Can RX7 injectors be had pretty cheaply? What years would you suggest?
Yes. Have a Wideband.
Kind of ran out of financial gas and trying to save what I have for enough dyne to map a safe setup.

460's/550's can be had for 60-200 depending on your deal finding skills and whether they've been cleaned/flowtested or not
Throw everything on, throw on 1.8 injectors, bump up fuel with fmu to squeeze a bit more fuel out of em, probably get to 200whp and start saving up for injectors.
Boost is addicting.
Only old men and girls stay at 5psi for any significant period of time

Get big injectors and be done. Since you sprung for an AEM instead of a megasquirt you must be loaded, so you can throw a few bills at injectors. Seriously though, 10 psi is my minimum now.

About 8psi intercooled is where I want be at this point. What's the cheapest injector I can get that will do this reliably without FPR? Already installed a walbro.
I can probably get something back money wise by selling the BEGi FMU and MSD that came with the kit.

Those should be good for 8-10 psi.

You would need resistors. 10 ohm resistors on each injectors or a honda resistor pack for which i have a super awesome diagram. There may also be a setting or something in your aem (I dont know crap about those, search) where you can run low impedance injectors straight up.
Edit: Even though I am feeling mighty nice, you could post in the AEM forum and ask, or read the directions. I wont go that far for you.

Head over to the Rx7 forums and ask for naturally-aspirated S5 NA FC injectors - they were in Rx7s from 89-91. You should be able to get a set for about $50. Send them to Witchhunter or InjectorRehab or someone like that - you should be able to have them cleaned and flowed for $16-18/injector. You end up with a fresh, clean set of 460cc injectors for right around $120 - I ran my first setup with an MSPNP, Rx7 460s and a Walbro 190 for quite a while (sold them for RC750s, then swapped the 750s for ID1000s). At stock fuel pressure, 460s and a Walbro will support fuel for ~240whp. 550s and a Walbro will do just under 300whp. Beyond that you should be doing ID725s or ID1000s.

1.6 injectors will tap out before you hit full boost. You need larger injectors, that's not an option. If you want to install the AEM and leave the FMU in place to boost fuel pressure, that's a viable option for now, but I would suggest getting a set of Rx7 injectors and having them cleaned/flowtested for a cheap injector option.
