Ebay forced induction products...

IN addition to my 340 Duster I own a Mitsubish 3000GT which I supercharged about 2 years ago. I run just under 8psi of boost without an intercooler, however I spray (Water Alcohol Injection) when boost exceeds 2.5 pounds. Setup works very well and if you keep the compression ratio around 8 to 8.5 you should be able to use 87 octane. The WAI can effective raise the octane level to well over 110 with a 50/50 mix of water and methanol or alcohol. WAI has the added benefit to keeping the combustion chambers clean and helps cool the motor. Old school but still very viable and renewing interest.
