Myron, K-Jet is the winner all round. That's why Bosch dropped D-Jet - to use L and K for all markets. The injectors in K and the way they work produce a far superior mixture formation, and the transition from drive to coast and back again is much smoother. D-jet was impressive in its day, but the parts cost, batch fired injectors, primitive throttle switch, and manifold pressure sensor make it obsolete. Stick with K-jet - other than its limitations concerning camshaft timing, it works best. I have a modified B3E (Canadian model) in my daughter's 242GLT, and it uses a basic K-jet. Pulls like a freight train to 6500 RPM.
