hey all, was purousing around and stumbled across this....

most of you may already know about the DB4 or "marine" DB2, but i had never heard about it. Seems that it has much higher injection pressures of over 11k psi, where the DB2 only has around 6-7k psi. Im wondering if the DB4, if bolted on an old 6.2L would not only boost the pony count, but for highway cruising have improoved combustion efficiency and mileage. To that end, do yall think i would have to switch to marine injectors to work with the DB4 pump? or could the original injectors work with a good rebuild? maybe 6.5L injectors instead?
Or am i just way off base, and running a DB4 would require a complete tear down and custom rebuild of the engine with aftermarket components in order to keep from scattering parts all over the road?
