I know that the c20xe and c20let have squential injection.
But how about the c20ne / 20seh / 18(s)e?
A friend of mine is currently building a 20xe which will have the batch firing DTA e48 exp computer. With 45 TB's. He is now worried about the engine not running a smooth idle. The engine for the rest is total standard ( cams etc. )
I personally think that the engine will run a smooth idle since I hope that the c20ne etc. also have batch fire injection so that I can say look at those engines.
