Can D-jet handle a bored engine?

I plan on increasing the displacement of my volvo 164 by .15L by boring the block out to use different piston, something very common in the volvo 140, would D-jet be able to handle that much of am increase? Should I get 5% larger injectors? It doesn't seem like much, but I am unfamiliar enough with the system, that I want to check.

Hi Pieter,
the D-Jetronic is actually a closed system and precisely matched to the series engines.
Changes to the engine require changes to the D-Jetronic, and these are always experimental.

You won't find any higher flow injectors. The original ones have a certain tolerance - but if someone would select them, they would be extremely expensive. Other injectors do not fit the system and the China productions are unusable.

However, a 10% increase in fuel pressure would provide the 5% flow you need.
That's the way I'd go.

We have several Opel-users here who have changed the block from 2800 to 3000 cc - and it works without probs.
But if a modified camshaft is added, you need your own, very individual setup, which is associated with Dyno work and so on.
