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.
