L-jetronics or K-jetronics

i was just on a site that said that the 323i with k-jetronics puts out 150hp when ljetronic of the same years puts out 139hp is this right?

L-jet and K-jet were never made in the same year. K-jet 323's are E21's L-jet are E30's. Peak power figures may be slightly better for the K-jet system but the E21 is still slower despite have a weight advantage over the E30 so I would imagine the K-jet connot match the L-jet across the whole rev range.

the charts at the bottom of the page the stats are for e30's

I was pretty sure it was the other way round. The early E30 323i had 139hp but that was later upped to 150hp. I had one of the later 323i (1985) and that was L-jet.

yeah it could be a typo. its just that my 520i (kjet) goes alot harder than my 320i(ljet) but then again the 5's a manual and the 3 is an auto.

Russian web site......highly suspect.

Workshop manual says,

K-jet 142.4 HP @ 5800rpm (mechanical injection E21 323 only)

L-jet 138.7 HP @ 5700rpm (early E30 323)

L-jet 150 HP @ 6000rpm (mid 84 E30 on)

no, its not the rev limit.

on the later 731 heads they increased the inlet port size. Thats where the power came from.
