I have heard that Nick will also offer a turbo kit together with his electomotive system. And he told me that the harmonic balancer does not have to be machined.
Maybe I am telling too much already, sorry Nick. |

Dr Tommy,
The Electromotive system, mentioned in this thread, is an electronic, crank-fired, ignition system. The beauty lies in that it provides very precise ignition timing and adjustment. When used on a 308, it replaces both distributors and the stock ignition coils. It provides a high energy and long duration spark, thought to be especially beneficial for lean mixtures.
Preciseness is obtained by eliminating all ignition system mechanical components, especially the mechanical advance mechanism and points, which are subject to wear and corrosion. When the trigger wheel is mounted to the crank (it�s also possible to mount it to the end of the cam but you need a smaller trigger wheel with more teeth � not as precise IMHO), vagaries associated with cam drive and valve loads are also eliminated. A separate integrated coil is dedicated to every 2-cylinders. Every cylinder fires on every crank revolution. The extra firing per revolution causes no harm. Vacuum advance/retard for load control and a map sensor input can also be accommodated.
The HPV-1 model provides adjustability by turning dials located on the main module. Adjustments provided are an initial advance setting, a constant for 1000 rpm and below, a separate linear advance curve between 1000-3000 rpm, and another linear advance/retard curve effective from 3000-8000 rpm. An integrated soft rev-limiter can be set anywhere up to 8000 rpm, which effectively cuts spark to the plugs at the desired threshold.
The more sophisticated HPV-3B model, provides programmability via a computer interface and special software where I believe up to 10 separate linear ramps can be defined.
The down side to this installation is that the harmonic damper must be machined to accommodate the trigger wheel where radial runout must be tightly controlled ( I believe Nick S can provide a no maching required kit but I don�t have any of the details). A hall effect sensor needs to be mounted to the front of the engine (drill/tap/fabricate a bracket), the distributors must be removed (need to fabricate a couple of blanking plates), the stock coils need to be removed (this is a good place to mount the main module but you again need to fabricate a bracket), and you need a tach amplifier (an MSD part) to make the stock tach work. A beefy (8-10 AWG is recommended for a front mounted battery in a mid engine car) power supply circuit is required to power the coils. Lastly, you probably can't use the stock plug wires and wire looms. The high voltage pulse can induce unwanted firing in adjacent plug wires; therefor you must pay attention to plug wire separation. Carbon core spark plug wire is recommended for compatibility with the Electromotive electronics (it needs a minimum amount of electrical resistance to function properly) and control EMI/RFI emissions/susceptibility (a very tightly coiled small gauge metallic conductor, such a Magnecor 7-9 mm wire, is probably the best choice, but pricey - other coiled conductors are iffy due to undesirable coil-to-coil separation).
When properly installed and setup, timing is rock solid but can be easily adjusted. There is no voltage reduction at high rpms because the multiple coils have ample time to recharge between firings. There are no distributor caps, rotors, or points to replace or mechanical advance mechanisms to corrode or wear. There is no ignition-timing mismatch, resulting from multiple distributors; one module controls all cylinders.
I hope this helps. Bill |

Tommy:
Go to one of our sponsors web page, Nick Forza Ferrari. Or call him. He will explain it to you - electronic ignition system, that's what it is.

what is an electromotive system? |

Eric,
I installed an HPV-1 in my 78 308 GTS. For emissions purposes (varying dynamometer loads at 25 mph), I installed the trigger wheel at 6 degrees ATDC (to control NOx).
Current HPV-1 advance settings are:
Init rpm: +3 degrees gives effective 3 ATDC
3000 rpm: +25(max) degrees gives effective 22 BTDC
8000 rpm: +10(max) degrees gives effective 32 BTDC
After emissions testing, I plan to bump up initial to perhaps +7, for effective settings of 4, 29, and 39 BTDC, then adjust from there based upon road testing.
Where did you set your trigger wheel and what settings are you using?
Thanks,
Bill |

Today she made her first run in over a year!! She Fired up!
Now I only need a L. Rear shock/spring, a trunk zipper cover, a tool kit, carpet kit.
Thanks everyone for the input, the electromotive system works well, now for the fine tune!

Erik,
In addition to TrueChoice, Koni North America also rebuilds shocks. You may be better off purchasing new ones while they're still available. New ones will cost about 250-350 per pair if I recall correctly. Bill |

Try these guys, I spoke with them and they seem very knowledgeable and can perform total rebuild and even match springs based on your specific application requirements.

I can tell you the oil lines are hard to find commercially. I build hydraulic hoses at work occasionally, so when I decided to do the rebuild, I said to myself "I'll make my own hoses, no problem". Well if I only knew then! The banjo fittings aren't too difficult to find, its the threaded part that is the problem. The threading is metric, there are virtually no suppliers of metric hydraulic fittings. We also have a guy come by our shop from Finning who builds hoses too, he just laughed when I asked him if he had metric fittings. I have a few more suppliers to go and ask yet, so when I build my hoses, you can be sure that I'll make the info known to all.
You may be wondering why I don't use the existing fittings and just have them crimped on to new hose. If I never find replacements, I can still use the old hoses (which don't leak, but weep a little at the connection). |
