K-jets are better for cold weather when working right, which is no big deal really. I'd advocate keeping them, if possible. Much less loss in economy and better engine wear characteristics than the LH-jet. A block heater and oil/water heat exchanger might be wise for cold running, along with a mild battery blanket, plastic tray, metal splash pan with vents blocked off, and something to block off the radiator (sheet of stainless steel for damper areas of AK?).
The parts car is an '84. LH2.0, high compression, automatic B23F engine, raised trim on the doors, DL model car with enamel paint. Nice harness in the parts car, pity to blow it open, it has value..ones in that cold weather condition updated volvo tag are very very hard to find. Pity to part it. Auto-auto is a fast swap.
I'd make it work right with what it came with more or less. B23 engine can be a nice powerplant change, if so desired. It can work well in an early car as a seamless swap with no signs of anything different with the original CI (k-jet) FI.
K-jets or conjoined manifold with airbox and functional (not too warm once "hot") preheat and a good set of stroms or SUs are the ticket for the cold. Uncle Olaf had it right. LH EFI is crap in the cold. Starts and idles good. Hard on economy, hard on the motor.
the problem is the "working right" part. My 80 kjet 240 wasn't super great for cold starting it would freeze up, I also had an 84 Saab with kjet which was even more useless. I have a 87 saab turbo right now with LH and it starts up perfect no matter what. You're right about the SUs my 144 always starts up in the cold!
