Injection for an Essex
I have a 1979 W reg Scimitar and I want to fit a multi-point injection system. Has anyone else done it?
When you increase the compression of any engine you make it more thermodynamically efficient, that makes it more powerful.

Never try and argue with an idiot. They drag you down to their level, then beat you based on experience.

That looks expensive my own engine is has a Weber DGAS, I'll fit a mega squirt ECU, convert the DGAS to a throttle body with a Volvo TPS fit the injectors and fuel rail from a 350Z. A Bosch inline pump. I need an injection system to convert my engine to ethanol.

Are 350z injectors ethanol safe? I’ve seen mention of specific injectors for ethanol but usually referring to specific vehicles for the Brazilian market although Saab did an E85-compatible engine (and I’m sure others did too).
As a side note, that’s an odd choice for a Profile Signature:
“Although ethanol has 3/4 the energy density of petrol it has really high octane I think if we convert to ethanol with high enough compression we can achieve more power. 275HP might be possible with an Essex engine, but you would need 16.5 to 1 compression.”
Did you mean to reply to a post rather than add it as a signature?

The Essex would be a good start for E100 as the additional loads at those kind of CR numbers would wreck most engines. The Essex is over-engineered thanks to it’s planned diesel application. It’s an interesting subject that hasn’t really taken off (despite being around for decades).

The hardest part is modifying the inlet manifold to accept injectors esp the centre 2 as you won't get much of an angle

The heavy build of the Essex engine is one reason why I use it. The heron head is the other, I was able to get cast pistons to fit easier I didn't need to go to the expense of forged domed pistons because of ethanol's low energy density. As the ethanol engine was an MoD radar station emergency generator I don't know what kind of cam it's got fitted. I do know if I re-built my Scimitar Essex to 16.5 to 1 it would do 275HP

We built a sprint car that ran a triple carb inlet manifold with 6 TBs. Proved to be far more tractable then triple carbs.
I don’t see how you can get that kind of CR from a Essex and still clear the valves? 11:1 is tight with 300/310 deg cam.

As I said I don't know what cam it has, it might be the distance the piston is from the head at tdc

I was referring to the signature, Mike.

The injectors as is are might not be ethanol safe, but once I've remanufactured them they will be.
