2130 cc B20 : D- or K-jet ? Megasquirt?? 120-130

posted by  someone claiming to be paul on  Mon Apr 26 09:12 CST 2004 [RELATED]

The B20/k-jet was used in the '74 140 and '75 240 models- their engine compartments have a ton of room compared to the 122's.

In your picture, half the fuel distributor would be mounted on the passenger side in front of the radiator, and the other half behind the radiator. Unlike the 140/240, the 122 has sheet metal in the way.

Phil did post a picture of a 122 with K-jet. The fuel distributor is mounted in the battery box, and looks like they used a B21F fuel ditributor. The air box from the early B20/K-jet looks to large to fit there.

I had the same issues when I was thinking of K-jet in my 122. The space in the 122 engine compartment is valuable real estate. Electronic fuel injection would save space (especially, if A/C or Power brakes are in there).

My problem with D-jet is that the technology/equipment is over 30 years old, and I think Volvo only used it for two years. MS uses the more recent EFI technology, and I'm assuming would give better performance (HP/MPG)than the D-jet/K-jet with the use of oxygen sensors and air massing to consistently adjust the gas mixture.

Plus, MS can be more flexible. There's alot potential of mixing and matching of parts with MS. People use new and used parts to complete their MS setup.
