Headers? Go custom. Nobody makes them. We suggest pulling your EM'*, repairing the cracks (you have them), and welding the outside of the flange so you can port out the OEM weld from the inside.
Bigger injectors? You won't gain from them. They're managed by the PCM and you'll have to add alot more power to outflow the stock injectors. I'm running more power than any non-nitrous Series 1 on this Forum, and I'm still on stock injectors. Besides, with bigger injectors you'll need a custom PCM burn, and you'll need to do alot, and KNOW alot before you can even think about doing that. Nobody on this Forum is running a custom PCM on a 92-95 SSEi from the only known source for them.
Adjustable regulator won't get you anything for a long time either. That'* something you do when you develop enough power to outflow the system, and you'll need a bigger fuel pump to go with it. AFPR is a tuning device, not a power-adder.
You won't gain from an aftermarket ignition system either. I think only 1 of the top-25 Bonnevilles on this Forum is running one. The stock ignition will carry you quite far in Performance.
My suggestions for you:
1. Get a scantool. It'* required.
2. Check your fuel pressure. It'* required.
3. After 1 and 2, scan for KR on a warm/hot day with the stock pulley.
4. Add a custom intake (shielded from the engine bay) or a K&N drop in filter witha ported airbox.
5. High-flow cat. Especially if yours is original.
6. 2.2 or 2.3" supercharger pulley if your fuel pressure and KR scans are good.
7. Jet Stage 2 PCM.
8. Start saving for a transmission.
Once you've added the 30hp or so listed above, and you want more, you'll be in a good position to push farther. You have to do this in steps to be able to resolve tuning issues in between mods.
