Based on your description of the 2.7, I assume it hasn't received the recommended case mods? IMO, 52mm manifolds would be overkill on a 2.7 for anything but a full blown race motor. I'm old school and prefer dealing with carbs, but EFI is definitely more controllable and stable over a wider array of conditions when properly set up. I agree on the CIS, can be made to be very reliable, but lots of very expensive components (fuel dist, WUR, etc) to replace when it misbehaves. Don't be too quick to sell, values continue to rise, even mid-year cars with ramshackle 2.7's are rising. Would definitely like to se a picture.Well I have a mid year Targa with a very ramshackle 2.7 built from junk bits. I was planning to make up little short manifolds and fit ST 1050 throttle bodies (52mm IIRC).
Even though Rusefi isnt quite as polished as the MS series, I like it better because it uses an ARM processor core. I have worked with this processor a good bit. It also has much more potential future development due to using this processor, as well as being cheaper overall. Plus, without getting into a political debate, i truly hate the drama and crap surrounding MS now. Not to mention how bad the licensing agreements are.
Even though my engine has the CIS pistons in it, I would venture to say that swapping to anything without the trapdoor fuel distributor would improve things. Except maybe reliability. A sorted CIS engine will take you around the world and back home again with no grief.
All this is assuming I don't sell the thing.
I will poke around and see if i have some pics of it. I am sure i do someplace. Right now its inside of a shed at my parents.
