Turbo Mini Forums

Thanks for the comments.

I can get a slighty better angle for the injectors when I make the real one by putting the real mounting bosses closer to the head but I can only lean them back so far before it becomes impossible to fit the fuel rail connection.
I also thought about bringing them in from the side but would that then favour one cylinder? Last thing I want with everything that is known about the siamese problem, is to throw another random variable in !!!

At the moment it is a compromise as to how high/how far back. Currently determined, as you say, by the compressor outlet - at the moment I've just reversed the standard one, I could make my own and get a bit lower but then the plenum starts getting too close to the exhaust manifold and turbine and I want to minimise heat transfer.
As for going further back, with a custom compressor outlet, yes (and I could further improve injector angle) but I'm sure I've read somewhere that the runner length (plenum to inlet valve) needs to be as short as possible.
