Aftermarket FI options for Type 4 motors 2056 or larger, Who here has gone this route and is it worth it? What options do we have? Options

[DRPHIL914]

i started looking into this 2 years ago when i was planning my rebuild motor after the drpped valve seat on the OEM motor.
I ended up building a nice 2056 with increased compression, brand new heads, counter balanced crank and of course the cam is performance minded as well.
to start i installed the d-jet and later last year i added a 50mm bored out stock throttle body from Tangerine/Chris Foley. Yes this helped a great deal, but we are still limited due to the d-jet and the MPS. So there are a few people out there that make ITB( independant throttle body) that could be used.
One is Jenvey, and i see that PMB is carrying those. It looks ike they are mated to what ever IDF intake manifold you choose. there are 40, 45, 48 options. mated with 350cc injectors.
I am wondering other than the CB performance stuff that has been available for a while, others have come to the table, who here has played around with this ? over the years ive read a lot on others using the megasquirt and micro etc and it seemd they were very difficult to tune and set up with lots of problems, trial and error.

I am looking for advice on what to stay away from and what are the pitfalls and mistakes we can avoid before jumping into this.

Look forward to some input, thanks!!

Probably a stupid question but are Holley sniper and similar systems too big for the Type IV? With 4 bbl intake "manifolds" available seems like that could work (if not too big).

It's a valid question and I think the main issue with the Sniper EFI systems is that you lose the port injection and revert to a throttle body injection which will cause fuel atomization problems due to the long runners.

The 4 bbl might be too big but they do offer a 1bbl that may or may not fit in place of the throttle body on a 2.0 setup.
