regina vs bosch
I have owned a 94 940 with a bosch system and it has been reliable for the almost 20 years that I have owned it. I saw a 94 940 but with a regina system and was wondering if they are better worse or equal to the bosch system in terms of reliability and ease of repairs. Both car are non turbo.

I also have a '89 740 NA with the Bosch system. That car needed a maf sensor...also a kinda pricey part...but one that's not used in the regina system. All in all I would say they are equal. That Bosch system has driven your 940 into 2016. The same could be said of the regina system on the other 940. |
the only real downside of Regina is fewer people are familiar with troubleshooting it.

And many parts people assume all 740/940 are Bosch so sometimes it can become a hassle to get spares. Even worse with front mounted distributors on some '93-'94 940. One has to ask for 240 wires, distributor caps, etc. The Regina lacks a MAFS and a second fuel pump which is a plus. Overall Regina is fine...

It has what looks like a regina coil... but i pulled and bought the fuel pump and filter assembly from underneath the car... and i pulled and bought the fuel pump / sender assembly from the fuel tank... Both of these pumps i expected to only find on a Bosch system...but that first pic is a regina coil right? |
regina and bosch LH use the same fuel pressures and delivery volumes, so either pump system works for either type. yes, I've heard of hybrids that had regina injection/ignition but bosch pumps.
|
So i could use these fuel pumps on my 1989 740 with the lh2.4?
And could i use the underneath the car pump on a 1992 240 with the bosch lh2.4? I bought them with the hope/belief that i could...and the fact that they look new and cost $40 for the pair. |
If this car had both pumps and a Regina coil then it's one of those rare "hybrids", in some 1990 only I believe... The fuel pumps must be Bosch then with the Regina coil--the pumps wouldn't readily swap into a true Regina car... Uncharted waters for me at least.

Of the 3 non turbo redblocks our household is driving right now 2 have the Bosch lh2.4 system ('89 740 and '92 240) and 1 has the regina ('92 940).
The regina car had its fuel pump replaced a few months ago. That car has only the one fuel pump in the tank. The 2 Bosch cars are running on their original fuel pumps so far as i know. I'm thinking the main fuel pump under the car that i bought should work on either the 240 or the 740. But I don't think the in tank pump assembly will work on the 240...only the 740. I'll find out someday I'm sure. The car at the jy was 1990...musta been one of them hybrids...with a wrecked front end. |
note that a turbo car (they are all LH) requires higher volume fuel pumps than a non-turbo (you can momentarily get single digit miles/gallon with a turbo during full throttle acceleration).
