EFI in spica manifold?

[junglejustice]

Well, in addition to Dawie from Glenwood's own personal Montreal that was punched out to around 3.3-3.4 litres using Milano Verde 3.0 pistons (as mentioned in another thread), he has also converted another Montreal off of SPICA and on to full EFI for another customer down in SA.

In that scenario they bored out the stock Monty SPICA manifolds to accept a Bosch injector. You can run the GoTech Pro or the new GoTech Pro-X, cap-off the old dizzy hole, install a 60-2 crank pulley trigger-wheel with a magnetic pickup, multiple coils and completely eliminate the distributor (and the mechanical SPICA) that way!

In a similar conversion here in the US, we took an Alfetta 2000 down at Group 2 and used a threaded Ford injector and tapped that in to the standard SPICA manifold, added a magnetic hal-sender to the stock dizzy and ran the GoTech Standard EFI with that one.

You remove vacuum - lock the dizzy at zero advance - and simply let it distribute spark based on the laptop-programmable timing commands of the GoTech. You can even do this coil-fire-direct via the stock coil like I did on my street Milano Verde - works just fine. (In the case of the Alfetta we chose to use a simple new after-market single-output coil that still dumps right in to the stock dizzy.

Both of these scenarios are lower-cost alternatives to complete replacement of the standard manifolds with individual throttle-bodies! Either way, now you're running fully-programmable fuel and spark.

threaded Ford injector? do you have a pic of one? I have never seen that type.

The Bosch injectors I used are "Ford Motor Sport" ones... but just you typical bosch injectors. The only difference is that they are sold as a matched set of 8.

Brought from Summit part number: FMS-M-9593-A302F. However these are only 24 lbs/min or 255 cc/min. injectors... But then the Montreal is only 2 1300cc engines so I'd expect with a 4 cylinder 1750 or 2000 engine you might require more flow.

However as a comparision, the flow rate for the bosch 0280-150-702 injectors which are fitted to the Milano, Alfa 33 16v, and 164 3.0lt are rated at 18 lbs/min or 189.2 cc/min. And that rating is with the fuel presure at 43.5 psi from memory.
