I am looking to see if doing a conversion is worth the effort and expense. My twin SU's are working fine, but I would like a better fuel economy, and less polution(with FI I should be able to to fit a catylitic converter as well). I have already swithched to a FI head from a B20(valve seals are a great oil consumption reducer), and have the old Bosch injectors from a 72 1800es, can they be used with mega squirt. Your replys are welcomed as I canT seem get replys from there web-site.

Thanks

Yvan

I've megasquirted my '65 122, and it was worth it. Not only did I get more power, I got more throttle response. I mean alot more of both!

I'm running a B21F engine in my 122, but the fuel setup would be similar. I used a surge tank for fuel starvation, and a 240 fuel pump setup. Here are some links to the surge tank and fuel pump setup:

Here's a link to a 122 with a B20/D-jet setup:

It should be close to how you want to setup your MS. Go with a wideband oxygen sensor!

Yep, somewhat well trod path by now.

You can reuse most of the D-Jet hardware, pump, injectors, manifold, fuel rail, engine temp, air temp sensors. You don't need the finicky MAP sensor. You'll need to replace the throttle switch with a potentiometer design, or you could use MAP based accerlation enrichment. Supposedly you'll need a manifold pressure referenced fuel pressure regulator, although from a theoretical point of view I'm not sure why you can't just fudge the VE table to account for the differing effective fuel pressure. I think you'll need a resistor pack for the injectors if using a 'plain' MS box.

I'd get it up and running on the fuel first, then tackle the ignition as a separate second step if I were you.
