I've thought about doing a Megasquirt for a while now to replace my carbs. I have a Mallory that works great, so to keep the initial cost down as well as keep it simple, I want to do fuel only, but have an upgrade path available for ignition later. Ideally if this could be done for under $500 that would be fantastic.
So... What is the easiest, cheapest, most simple solution for induction parts? Throttle bodies, injectors, TPS, etc...? Which MS unit has the flexibility to do fuel now and ignotion later without starting all over again with a different ECU? Engine is a 2056 that is built on a 1.8 case and heads with a 2.0 crank, rods and P/Cs. Currently running dual Weber 40 IDFs.

My thoughts:
The ECU setup is going to eat up most of your budget, so you're going to need to use as many stock components as possible. The TPS is not compatible with any new system. Throttle bodies will be out of your price range, and without a bunch of R&D, stock FI setup will be your best bet. You're not going to find a 'bolt on' setup since the TPS isn't compatible (as mentioned) and the injectors are low impedance and most new systems use high impedance injectors. You'll need to fabricate your own wiring harness, and I've found that this is the most PITA part of the setup. Wire crimp integrity is important, as well as wire routing and length. My best recommendation would be to get a 'junker' motor that you can fire on a test stand with the FI setup. Get it all working reliably before you make the swap, then sell the 'junker'. I always hate to see a running car get relegated to the R&D cycle. Things will go wrong and cause problems. Driving your car while you're figuring it out is obviously preferable.
