I'm installing a 12mm pump in my Volvo D24T (6 cylinder version of the 1.6 IDI), and I'm getting my injectors tested (currently Monarch GTD nozzles @163 bar).
If they need work - what nozzles do I go for?
On the D24T forum, the following have been tried?:
Standard 293 @ 155 bar
GTD 273 @ 165 bar
297 @ 170 bar
XUD @ 175 bar
There seems to be no definitive answer of which are best, and why. The XUD is a very recent test, and appears to be successful with the 12mm pump.
As the 1.6 is the same design as the 2.4, I wonder if any testing of different nozzles has been done on this forum? Anyone ran the XUD nozzles for any reasonable time?
