to expand on "sophisticated engine management" - a key element for high boost and higher static compression ratios living together peacefully on modern cars is knock sensing and the ability to retard ignition timing dynamically. That sort of tech can be added to an old air-cooled sled. There are standalone ignition system solutions like
JS Safeguard, or most fully featured EFI/EM systems will have knock sensing options.
