93 940 b200ft and b230ft Engine Management Similarities?

If someone has knowledge of these 2 engines assistance would be appreciated.

Do they share engine sensors etc?
If most components are the same what are the differences of non internal engine components?
Is there an appreciable economy advantage/power disadvantage in the smaller capacity?
Why did Volvo produce both engines concurrently?

I have come across a b200ft that has been imported from Hong Kong into Australia.As they were not sold in Australia I do not want to buy a car that is hard to source parts for.

Thankyou in advance,
Hibbo

Frankly, the only parts that differ are the pistons and rings. Consider it the same engine. Some countries have tax based on cc and in those countries, Volvo offered these engines. They are very common in the UK and they do offer a slightly better economy and, in my opinion, considerable difference in performance although in the turbo version like this, that is less. If it is an automatic, forget so called inspired driving. Of course, any trim equipment for the B230 engines will work equally well on the B200. I suspect, though, that the control boxes are different so chips might be difficult to obtain. I am not sure if the injectors are the same.

Thanks George.

I have been able to do some cross referencing at Euro Car Parts UK. It seems most sensors and components,as you've stated, are the same. The exceptions being crank/impulse sensor and maybe O2 sensor.

Do you know the fuel consumption advantage of the b200ft over the b230ft?

Regards,

I am surprised that some sensors would differ but I suppose that the 02 sensor makes sense. I would not trust Euro Car Parts though, check with a Volvo dealer.

The fuel consumption difference is minor.

I can give you fuel economy figures for my 94 940 2.0 SE Turbo Estate 5 spd 144k if they are any help. They are in Imperial Gallons.
For 1000 mile trip in UK on Motorways and A roads with 5 adults and 50% luggage (keeping to the speed limits) 29.3 MPG.
For 200 mile trip in Ireland 3 adults no luggage ( max 60 MPH) it did 34.2 mpg.
For 250 mile trip incl towing 1.7 tonne trailer for 115 miles (max 60 mph) it did 29.4 mpg.
The 2 shorter trips are full tank to full tank at the same pump in the same fuel station.
For local Urban driving (not including any heavy stop-start town driving) I get 26.5 mpg.
I have carried out the Boost10K treatment at 139k which may help.

My 940 2.3 Low Pressure Turbo estate with autobox and air con does 600 km on 75 litres of 98 unleaded. This is mixed driving, mostly what I call semiurban (smaller towns and villages, no real traffic jams) and motorways at 120-130 kph.

My father-in-law has a basic 740 GL B200E with 5 speed manual, no air con and 60 litre tank. He does 500 miles, but that is almost entirely motorway.

All,
I don't see why the crank/ impulse sensor would be different because it is only measuring revoltions of the engine, equally why have a different O2 sensor. It is more likely to be the mapping of the outputs of these sensors to the engine/fuel management system. Certainly no expert in this area but would have thought that they would have the appropriate skillsets in Aus to remap the engine management system just like they do any other re-mapping or chipped car - might be worth a cross-post to the performance scetion as they tend to play with their setttings more than some of us.

Of course ultimately, a b200ft is a 2 litre and a b230ft is 2.3 litres so the first must be more economical (well in brick terms) than a 2.3 whereas a 2.3 will give you more low down capability - on the flat anyway. The b230 ft has a marginally higher compression ratio 8.7 vs 8.5 on the b200ft, both have the same T cam and the nly other difference I can see is the piston bore size and the rings to fit.

All in all it is a good engine - I have the b200ft - and I gues it depends if you are going to be doing a ot of towing, the tax rate and the cost of fuel which determines the engine you go for.

Peter,
Does the good green book advise differently (note to self must get a copy for the 900 B200 FT and the LH Jetronic 2.4!)

Oh yes, do not get me wrong. I may be slagging off the two litre but only on performance and on the more general issue of why have one if it is not a tax issue. Quality wise it is as good as any other red block engine.

Having said all this, the 940 SE 2 litre turbo manual that I had for a while was the best of the three two litre ones I had.

The main difference between the two versions of the same engine is that the B200FT has only 10bhp less than the B230FT. This means that the power of the B200FT is very much the same as the non-turbo B234F. This is the twin-cam, 16-valve version of the B230. There was also a B204FT/GT but I think it was only available for the continental market, although it is listed as UK option. That version has more power than a B230FT!! It is interesting to note that the B230ET was available to the UK market up till at least 1996 in 940s (Sports Edition).

All the best, Peter

Thanks all. Your responses are appreciated.

Further investigation has revealed the car does not have ABS. This was a surprise. From '89, all turbos sold in Australia came with ABS. It may have been standard on na models as well. My wife's na 93 940 GL has ABS.

A young family who drove into my path while I was doing 100kph, despite a big shock, were able to continue on their way. My ABS saved them from being 'T' boned. An excellent safety feature!

Decision to purchase has not yet been made. Fortunately Volvos are not the flavour of the month in Australia and this reduces the need for a quick decision.

Take care,
Hibbo
