Daimler V8 Modern Ignition and Injection Conversion
Discussion
Hi Fandango,
Unfortunately due to illness of both myself and my father it got postponed for quite some time.
Ironically I've been working on it quite a bit lately and it is almost ready for test bedding.
I have done most of the hard bits but it wont be cheap to do when finished!
The ECU is £700, plus the injectors, wiring, and other bits needed will make it closer to £1500 in parts alone. Then there's the machining, welding, etc.
By the time its finished I can imagine it will cost £2500 easily if you did most of it yourself.
Then theres the tuning needed to get it running right! That will take quite some time and effort.
Please don't be under any illusion its a quick and easy fix because its not.
What it will do is allow you to gain more power from the engine but more importantly better emissions and far better fuel economy.

Good on you Andrew with the project. That 'huffed' Daimler/Seirra estate always impressed me. The fact that the Daimler engine is capable of making significant horsepower gains with a low pressure 'huffer' indicates (to me anyway) that the limiting factor of a non-blown Daimler engine just has to be the inlet tract. Have you considered using the Procharger blower? - this really seems to be the hot tip on medium and large capacity V8's. With a small capacity engine like the 2.5 a low boost without intercooling should be feasible. Question will be however - is there sufficient room to mount the blower?
Your right, the inlet is the worst part of the engine.
It was never ment to stay that way but the development team ran out of money and time to redesign it and so it went into production.
The issue arises due to the fact the manifold over fuels the outer cylinders and under fuels the inner cylinders due to its terrible angles within the manifold pipes. The fuel hits the outer wall and drops out flowing into the out cylinders.
Dad has always said you can potentially double the horsepower by running 8psi of boost which has always been done with a GMC 3/71 or Wade.
However we are now looking at the modern Eatons. Rear entry and quite shallow they will mount happily within the engine bay as they sit lower than the carbs and filters do as standard. That is what we plan to use after we get the NA injection Ignition system working reliably.

To be totally honest the cost of doing something like that compared to any prospective business just doesn't make it viable in my opinion.
Those who have this engine in their cars are generally happy to put up with it, those who aren't are generally rodders who will happily cut it about themselves anyway.
There are very few who are that seriously concerned as to avoid the engine because of it or fork out serious money for a short run of custom made manifolds to improve it.
The Ignition Injection system we're doing will struggle to make any money for us as a business venture due to the cost being quite high on top of what is already quite an expensive engine to rebuild anyway in comparable terms to other popular V8s. The only reason we're carrying it on is because we have a real interest in it for personal reasons.
There is a potential it will allow a Daimler transplant into more modern vehicles if it will make the emissions levels required, with the added benefit that if the law is ever changed because classic cars are deemed "too dirty" to allow unrestricted use of by the environmentalists then it could be argued that due to it reaching at least a fairly modern emissions rating (potentially equal to late 90's early 00's) it could be excempt from these restrictions.
