Been practicing my CAD, now almost good enough at it to draw up my own IDA-3 to motorcycle ITB adapters.
Cheapest way out for FI bodies and the CAD-CAM will be essentially free.

Of course the MS control and other hardware is still expensive.

Richard, Glad to hear your going with the Triumph throttle bodies. Hard to beat for bang for the buck. I read on one build they used VW injectors. Are you going to slant the adapters so the TB's are straight up?

Richard/SIA

Trying to squeeze out more time to practice my CAD.

Actually got this pretty well drawn up, but in an obsolete CAD program.
Now trying to learn a much new CAD software.
And yes my intent has been to angle the mounting face so that the FI bodies are vertical.

I've also been looking into other FI TB's.
Found some that are larger, and some that are also round all the way through.
Trying to get samples of each type to design around.
BMW units are bit expensive but may have some real advantages for linkage.

Now have a Fadal 15 to make the adapters on.

Been to busy to do physical work on the Trick-6, but that has not stopped my scheming!

Some time ago I bought an MSII 3.0 and additional parts on the cheap.
Seller apologized that he could not find the ECU.
Now he has found it, and is sending it to me next week.
So the bike F.I. bodies to Inglese IDA manifold conversion is back on the active project list.
Hoping I can make a simple adapter plate that the Porsche and Corvair crowd might also like.
There is a version already available but it's a very expensive Porsche specific kit.

Got the MS II today.
So here is where I am at right now.

Engine, 3.8 Buick V6 normally aspirated.
Intake is Inglese IR meant for Weber IDA-3's.
"Budget" EFI solution is Bike EFI bodies on custom adapters.
MS II 3.0 control hooked up an EDIS 6 and coil pack.

Not sure about wide or narrow band, or if injectors will high or low impedence.
Those are items I still need to buy.

I found a NOS 5" 36-1 timing wheel on feeBay for cheap.
What I have going here should eventually yield a distributor-less ignition and I.R. EFI.

My concern for the moment is that this is a freshly built engine with no prior run time.
So I'm thinking I need to run it in on a carb and maybe even a distributor before getting into "Tuning" a custom Ign/EFI system.

I suppose the Ignition should be simple and reliable enough that I may be able start and run without the distributor.
I would prefer that as I am hoping to use a Rover front cover and oil pump.
Changing covers may mean changing pulley sets.
Once run in I should be safe to swap the intake to the IR EFI.
Hoping I can find some "Maps" that will be close but I'm not seeing a lot of IR EFI in use for reference.

ACK!
Looking for am electric water pump to make mounting the alternator easier.
Moroso kit looks a bit flaky and bulky.
Mezier would be nice if it did not have a 4X price over ANY other unit! (Rover tax?)
SBC, BBC, SBF, Mopar, right around $200 or less.
BOP, $450!

No blankety-blank way that is justified.
Once the CNC program is written it's just time and material.
Not that much more time, and not that much more material.

I may just design my own adapter, then buy a $100.00 Summit racing SBC unit for the motor and impeller.

Reluctantly moving the Trick-6 back in the pecking order as it still needs a fair amount of creative engineering to make visible progress.
I will be working on the F.I. system and electric water pump to complete the engine over summer but suspension will probably have to wait for next winter.

For the moment I am going to concentrate on the '68 El Camino/327 Muncie/Jag IRS and Alfa Romeo powered Dio Tipo.
Right after  I have the few remaining '79 Alfa Romeo Spider details sorted so that I have more than a one-ton truck to drive each day.
No or very little scratch design required for any of these.

Richard/SIA

Been unable to do much on the Trick-6 but not at a complete stop.
At $2K+ for the TWM throttle bodies I'm learning/experimenting with CAD to see about fitting the Triumph 955 throttle bodies.

Coming along fairly well, particularly as I hardly know what I am doing!

Back from the dead?

FINALLY got "Lucky" and found a set of IDA-3's for "Only" $999.00!
40mm but they should work OK.
They are the easier answer since I no longer have my CNC machines.

Now, about jetting?

Trick-6 is not the main priority at the moment but I am pleased to get the carbs at last.
They were really the last major single expense.
