However given the cost on such a unit, you would be tempted to bin your old K Jetronic fuel system as well and go to a full EFI ECU that controls everything easily and seamlessly like a modern car.

Thanks for the suggestion. And there lies the rub!! Quite a slippery slope. I am enjoying the process of seeing what options are out there. This is too big a decision to just jump. My next step will be to consult with my engine builder and revisit my goals.

For Igniton I have 2 Bosch CDI boxes, 2 black coils, recurved Bosch twinplug dizzy ( not sure if it is modifeid or original) and have the Safeguard unit to pull timing under boost. I am told its all I need....but can it be improved on with either upgraded CDI+ boxes or going smart coil and ditching the distributor. It would be nice to know that any changes are improvements and can be paired to a full EFI conversion in future.

Maybe for me there is little need to make any changes....when do needs and wants and a 930 go hand and hand!! I really dont need more horse power but a llitte more would not upset me. I would like a litte more low end torgue below where the 7006 hits....and I think that could potentially be met with a 7200 Raptor of GT25r ball bearing turbo.....the latter being preferred BUT.....

The Safeguard pulls timing to a max of 16 degrees when it gets a boost signal ( not sure how but I do know that it is prgressive and can adjusted in up to 2 degree increments) and the recurved distributor may already be giving me all the vacuum advance I need off boost.

To your point if I get an EMS sytem to control ignition then I am onestep closer to EFI...


I read an old post today that a properly running and improved CIS system can handle 400-450 whp... WOW ....seems more than I thought was possible.
Now is that 450 on a dynojet or on a mustang dyno?.....all dyno hp is not created equal. What I do know is I have approx 350 mustang dyno hp at .9 bar on a fully built 3.4 and with an 8.41 ratio its more than enough and often too much to use it all before running out road.


If I have the fuel to safely run 1 bar at get a safe 375-400 ponies....and good crisp off boost low rpm respomse I would be happy....

heck....I am already HAPPY.....
