Hi, I have been to a samenar about this engine.
The 2.2 EJ wil give you about 136 HP but with the reduction and prop it is 170 KG. The 1.8 is about 130 KG. I forgot how many HP it is. The guy made his own EMS system, it runs very smooth but it is to havy. http://www.nvav.nl/vereniging/activiteiten/301-motoren-en-motormanagement It is a nice story but you need google translate.
