EFI in spica manifold?
Wondering if anyone has tried/succeeded in fitting electronic fuel injectors into a spica manifold? What type of injectors did you use? What type of manifold machining operations were involved? Fuel rail? Did you use megasquirt, haltech, electromitve, etc...? How did/does it run?

Hello...
Has anybody done this? Doesn't seem (famous last words) that complicated...

The spica injector looks very long.
I am going the other way I am adding a servo system to control the spica pump with a ECU.
but Jr. over at APE milled a spica Montreal v8 to take normal E-injectors.

i have looked into it...
i am trying to design a manifold to the ind. intake runners of the spica........to fit the l-jet injectors should not be too hard( i think)  just need to weld some bosses to hold the l-jet injectors down, going to buy some of that alumin -weld, they say it is harder than the alum. that you weld it to.....but you must wait, this well be a late spring sumer project, sorry, but e-mail me if you like. |

slyalfa,
I am EXTREMELY interested in your servo controlled SPICA. Would you mind creating a post detailing it?

I just started to take it apart last night. it was starting to act strange anyways.
what I would like to do is add the TPS and the triger wheel inside too.
I use pump wheel now for the trigger wheel and it works well.
as you can see I liike to try to keep the look stock looking. the biggest give away will be the lack of a dizzy

How do you have the knock mounted? and does it work well. And what bandpass do you have the knock filter set to(if the ECU you use let you set that)

Today I work with a free ECU and from that time my problem with this thing is gone.
But to tell you the truth the right setting for the knock sensor ( ECU setting ) is until today not really ready.
I will do it in the summertime.

drilled into the head? no problem of making a hole on a coolent passage or oil passage?
I was thinking if puting it on a strap like the lifting strap .
and where did you have it before?
BTW I am a VEMS developer.

There was a discussion about using SPICA manifolds for EFI some time ago on the Megasquirt board. The general consensus was that while it does work, the angle of the injectors is sub-optimal for EFI. Probably will never matter to anyone who is doing this but just thought I'd throw it out there. Something to do with the difference in pressure from the SPICA pump vs the EFI. The injector angle for the SPICA was designed with one pressure in mind and the EFI uses a I think lower pressure.
All that being said, I have seen the setup that Jim Steck did on Ken Wears' car and it is a work of art. As is the one on Brian's car.
