I want to put 2.7 bottom to mine m20b20 top (200 head). I would like to do it on Jetronic. We have lots of 2.7 + 2.5 and 2.7 +2.0 conversions in Poland but all off them are on Motronic.

Why i want to do it on Jetronic ?? Coz then car will look liek oryginal :P I dont want to have "200 BHP" just want to have more tourqe and bhp than standard 125 in m20b20.
Enybody done this before ?? Maybe somone knows somone who knows somone who done this ?? :D

Think the problem you will have is due to the relatively untuneable nature of Jetronic. Fueling requirements are going to be a lot different for a 2.7 compared with the 2.0.

Hey, i checkd and i have 731 head. So thats a good news. But i'm not sure that standard jetronic can give enough fuel.
