To carburate OR to not carburate Options

Restoring a 70 which will have a 76 2 liter. Currently has factory injection but guy who will be building engine for me is anti injection. I know this becomes personal decision but could use some input on pro/cons. Cost is a concern but so is practicality and performance.
Words of wisdom please.
Merry and Happy to all!

How much can we figure for a new programable FI system?
thanks

In kit form, DubShop used to have a nice dual ITB Megasquirt kit with wiring, all sensors, pump, etc., for about $3500. Currently showing Waiting on Throttle bodies and no pricing.

Get ready for price hike with devaluation of the dollar and supply chain issues!

It is the kit I'd love to do if I were going to stay /4 forever.

Fuel only SDS, using stock intake (stock pump, injectors, etc) and a DIY install can be done for $1072.* plus a wideband meter.

*Parts also needed (extra) MAP sensor 1 bar $73, TPS $93 (can be had at scrapyard), fuel pump relay $30 (optional but recommended).
This is the minimum extra parts needed, there's other options.

No dyno time required. Basic install time required for me is one weekend, for an amateur maybe 2-4 weekends. Tuning time for me on county back roads one hour, again for the amateur 2-4 times that number. Engine will fire up right away, with the included rich/lean knob I have no worries breaking in a new engine on SDS as you can adjust AFR on the fly.
Based on an engine with no mechanical issues. System can tolerate mild carb cam grinds, limited to the stock intake. Don't expect any more than stock performance on a stock engine, FI doesn't add HP.

NOTE crankfire "F" systems and crankfire E/MSD systems take much longer, as you have to remove the engine and fab a trigger mount.

I've done several of these /4 "D" systems on stock engines, they run great. I have SDS with crankfire on my 2.6L VW bug (T4 conversion) and I have a twin plug system I will install on my 3.0/6 conversion someday.

If you have the d-jet intake I would say $1000 is roughly the comfortable low end to do it yourself. It can be done for much less but with much greater time and effort, $1000 is the comfortable point for DIY. I did receive a notice that there are going to be price increases on Megasquirt hardware in the new year though, so that may change a bit.

Marios (dubshop) kit at $3500 includes $1000+ of ITBs and related hardware (and markup) that you can get by without if you already have the 2.0 intake and unless the motor is built up significantly over stock there is not any advantage to running ITBs. that being said it is a complete kit so if you are starting with nothing it may be the easy way to go. His harness is not specific to 914s though, at least not the last one i saw. Also the dubshops type 4 crank sensor, while still my personal favorite serup, does require dropping the engine to install in a 914.

Not sure if PMB is selling any systems for end user installation yet (or what they cost), but they have built out a few now that are 914 specific and use a trigger setup that replaces the distributor so you don't need to drop the engine.
