Carb vs Injection 1977 530I

Ok guys I'm frustrated with a no start problem on my 1977 530I considering going with a simpler 390 CFM Holley Carb on a Euro manifold like the E9 and E3 guys do. I have the parts and think it will help my car be more reliable since it gets used maybe 1500 miles a year. What do you think?

I think it will probably be easier to sort your car out leaving it as fuel injected, than doing a conversion.

That's like using napalm to start a BBQ. Yeah, you could, it would work, but it's not the right answer. And if your no start is ignition related it wouldn't even fix it.

Triple side-draft webers?
If I had the $'s this is what would replace my Zenith's, if only for the bling / noise

Yeah, that has it's points, but he was talking a plain old Holly 4 barrel.

I think you need a different fuel pump and get rid of the fuel return line.

Might just make more problems.

If you feel like a conversion is the way to go, what about programmable EFI (Petronix, Microtech, Haltech, etc)?

Cheers

That would be interesting.. Our cars in Europe ran a solex carb the Holley is much better overall IMO. I woulld use the manifold off my european car and fit with a low pressure fuel pump and regulator.

You may have already seen it, but for future reference here's a good read:

I had been investigating replacements for the zeniths on my 528 & came across it.

Thanks that's a good reference and have seen this conversion on some E24's as well. I think this will be in my future.
