https://www.boschautoparts.com/en/au...tId=0280156146 It also throws up the same injectors as i used - however i would suspect that's for the N/asp engines as the 804 came up as being for the turbo in all the searches. Can't seem to get any other results tonight, my internet has been playing up today and has only just come back up, i'll have a better look tomorrow.

Interesting.
The 146 injectors only seem to be suitable for NA cars according to most sellers though.... |

Mine was similar before, coming to life about 3500rpm so i'm guessing that the dirt/blockages in the injectors in mine were restricting it up to that point then they were open long enough for the dirt to be overcome bu quantity of fuel. The previous owner had it about 10 years as far as i can work out and i think he was a bit too gentle on the loud pedal. Since i adjusted the idle mixture, the torque has done the same as yours and shifted further down the rev range with no feel of overfueling at the high end. I'll have to see how the fuel economy is effected, hopefully improved! Starting is certainly more consistent, both hot and cold so that's a good start (pardon the pun!) and no more petrol-pong when i get in either! No pong after giving it the beans is an added bonus!

Beware of cheap chinese Bosch copies on ebay. I bought the 0280155830 blue injectors from a reputable seller stocking genuine stuff, they cost £70 each. Noting to be scared of with the resistor mod. It doesn't hack up the wiring and is completely reversible.

Just one question which I am sure has been answered indirectly
herein, but .... will those Bosch Gen 3 injectors go nicely as replacements in my B200F with LH2.4/EKZ16 .... it seems so? P.S. I also have one of those little Gunson GasTesters (might be Mk1 !!), but haven't used it since my 244DL years when it worked an absolute treat!! Bob. |

Apologies in reviving an old thread, I have been brainstorming on ways to improve our B200E in the Hearse prior to an engine upgrade to a 2.5 using a penta AQ151 block.
My question is, as the 531 head is not readily compatible with K-Jetronic injection due to different injectors and locations (learnt this yesterday) we will be keeping the current head and injection system. Could I benefit from an injector upgrade in a similar fashion to that seen on this thread? If so are there any recommendations anyone knows of? I am aware that the K-Jet uses mechanical injectors (more like a presuure valve), which appear quite different to modern EFI injectors. The internet is unusually quiet on K-Jet injectors and upgrades, but what I have found is as below, I don't know but it seems as the last three digit value increases, so does the power/engine size of their application, I couldn't find any info on flow rates etc but that may well be not apllicable due to the inherent differences between these and modern injectors. Volvo B200E standard 0 437 502 015 Volvo B200ET standard 0 437 502 020 Volvo B280E standard 0 437 502 022 Volvo group A 'gold' or Mercedes Benz brass upgrade injectors 0 437 502 047 Interestingly the 047 brass types are about £22 each whereas the others are £30 to £50 each I'd appreciate some wisdom on this! Thanks.
