940: regina vs bosch LH...?

[odinthewanderer]

alrighty....

well i am in the market for either a turbo or na 900...

while i am moderately sure all turbos are LH.... and i am moderately sure all 95s are LH...

where does that leave the rest of the NA 940s...

where most in the us regina... or were they mixed...?

i think i heard somewhere about cali cars being LH....


i honestly would prefer an na car for this purchase due to fuel economy, and its one less thing to fool with right now... in terms of play and maintenance.


but... i know LH and do not know regina...
also, while there seems to be a wealth of easily found info for LH, i do not see that kind of support for regina...

i wonder if avoiding regina is an excuse enough to go straight to a turbo car...

does regina offer any benefit other than the lack of an amm to break?
does regina offer any major downsides or problems when compared to LH?
im sure LH parts are easier to find as well...

which of these have egr?

thoughts?

experience?

thanks guys!

I had a 1990 740 with the regina system, I would stay away from them. I lived with electrical issues from the time the car was new. Nobody could fix it. When it came time to trade, I had a hard time getting rid of the car because of the regina system.

thanks... that is what i am looking for.
i wonder if 93+ has some LH scattered in there....
would be lovely if there was more to pic from than just 95...

You have the wrong impression. Most of the NA cars are Bosch LH 2.4 with some Regina cars in the mix. I wouldn't buy an NA 940 for the gas mileage. The difference is about 1 MPG. Not enough to give up the additional 50 hp on tap that you will have if you go with a turbo model. California Emissions Standards cars have the EGR. Later California Emissions Standards 940 NA models have EGR and Pulse Air.

thanks for the sorting Roy.
i guess i will just look for the cleanest one, turbo or not...

turbo would certainly be nice to pull the c scow we eventually plan on having...
and really not much more (as i see it) to trouble shoot if something goes wrong.

i have never really serviced or worked with any of the turbo stuff... but i sure would not mind having it.
its not like it will really complicate the car too much more on the whole... it is just one more thing to pay for when it needs upkeep....

Most stock turbos are built to last 100k + if the car you find has high mileage just factor in replacement cost of the turbo with what you can afford.

N/A 700/900 cars are kinda underpowered for towing, especially with an auto, which is all that was available after '91, and finding a manual n/a pre-'91 is a needle in a haystack.

You can find stick shift ~85-86 700s a fair bit, but those cars are real dated looking, often very electrically challenged and have falling headliners and trim and all that many times.

Later 93 updated Regina cars are better, but earlier 90-91 ones can sometimes be almost impossible to sort out some of the bugs. 940s often have Bosch lh n/a or turbo.

Turbo is ok, the oil just must be changed/topped religiously, and it has to be cooled down and warmed up not outright abusively. The cooling system is also much more stressed, I've had the heads off turbo cars many many times due to burst hoses, cruddy radiators, lazy fan clutches, et al. Some of those heads have not been reusable and a full rebuild of an n/a head with turbo exhaust valves and new exhaust studs with a surfaced manifold was a lasting fix. Sometimes someone will reinstall a turbo head that is fried and it will fail again catastrophically not too long thereafter.

If you just need to get around and need a car nowish, I'd look for an n/a one, but they are slow. You don't have to know a whole lot to keep it on the road and you don't had to budget as generously (or be wothout a car long) for a turbo or head failure from previous neglect/hacks as commonly, both of which am an be costly or time consuming to sort out.

You could also factor in the $.20 a gallon difference between 87 and 91 octane recommended for turbo engine. I had a 90 745na that had the lock up torque converter. It had very snappy performance and seemed to get excellent gas mileage. Wish I had kept it but don't know if it had L H or Regina. Only had it a short time and never worked on it. That was before gas became gold in CA, and I thought I needed more performance.

this all sounds like excellent advice... thankyou.

i am still on the fence....
i would love a turbo car...
but i would not mind an NA one...
i can live with an auto too... it would be nice on trips and the dog loved to rest his head there in the 240 before i pulled the auto out...

we will still have the 77 with the m46 if i need my stick fix
the real thing that draws me about the turbo.... is my wife, my brother and law, and i plan on buying a c scow, or something like that... having the turbo would be nice to tow it...

there is a turbo 92 745 that a board member has that i am currently thinking about... seems to be kept up quite nicely and has all the ipd goodies, new bushings, and then some...

there is also an NA 94 940 i need to call about... seems like it does not have a sunroof and has manual leather seats if that even exists....
no roof rack either... which i prefer... im not a fan of the factory ones


i missed a good 94 out in austin... cheap too... clean documented car that got hit and went to auction with 101k.... had an operating but bashed in door and tailgate... white with blue cloth...

FWIW, I've had great luck with Regina 1990/91 740's. Like 250K miles with nothing breaking. MAP sensors are dirt cheap. Fuel pumps are kinda cheap from Volvo, too.

Definitely had more issues with Bosch of the same vintage.

Noooooooooooooooo....... I wanted continuity!!!!!!!!!

[740volvo]

Iv had lh2.2, lh2.4 turbo cars and a Regina+T car, witch I drive now. The fuel economy is way higher with the Regina system vs the lh system. I myself much rather have a Regina system because of the fuel economy and reliability, cheaper parts ect, unless you have performance goals go with the lh system, allot of support for that system out there over the Regina system.
