Ok, the H1E has been on the bench long enough. What pump and injectors should be used to get enough fire in the hole to use this monster? The intake side seems to be the same as my H1C. The exh. side is much larger, 26 cm. Can the exh. side be downsized to work with my 5. 9. Also the center/bearing section is larger but retains the same bolt patterns as the H1C. Is ther a 14 or 16 cm housing with a 4" exhaust flange?
