"In 1992 catalytic converters became compulsory on all new cars sold in Europe. The impact has been dramatic - in the UK alone, harmful road transport emissions have fallen by 45%. This figure is set to fall yet further as older cars are gradually replaced with newer ones which meet the higher EU emissions standards" https://www.tenneco.com/catalytic_co...ns%20standards Basically from K reg onwards although some cars are still given a dispensation up to 1994/95 time whereby they don't necessarily have to meet the emissions (a BET test is used instead) and/or don't even need a cat. Further a car made after that time can legally have the cat removed if an LPG conversion is carried out but it must still meet the required emissions for that specification which is generally the same as a BET of 3.5% CO max and 1200ppm HC.

In the model year 89/90 engine options for 740/5 non-catalyser models were:
Base - B230KH GL and SE - B200E Turbo - B230GT GLE - B230E As of 1 Jan '90 all models including 760's were offered with the free option of upgrading to catalyser xxxx'F' engines (LH2.4). Bob |

That would also correspond to a similar percentage increase in fuel consumption against a well-maintained LH2.2. However, a similar comparison isn't available between the B230E and B230F as the B230E had K-Jet, although that could also be ordered with the KE-Jetronic which had a Lambda sensor, cat and a device (i can't remember the exact nature of the device now) to alter the fuel pressure to maintain the mixture correctly. Even after 28 (nearly 29) years, i'm still unconvinced that paralytic perverters (as i prefer to call them) are actually any benefit in the real world. They increase the loading on the engine by reducing the efficiency of the exhaust resulting in increased fuel consumption, they produce H2S (Hydrogen Sulphide) gas which is highly toxic as well as stinking of rotten eggs and for many people, are now the subject of theft from their vehicles. To me, that's a lose-lose-lose situation!

Thanks Dave ...I remember complaining to the dealer when mine went in for its free warranty service about the stink from under the drivers side!! 31 years later still there. They don't build cats like they used to!
My handbook states outputs for the B230E - 131hp @ 5500rpm / B230K - 117hp @ 5200rpm / B230F- 116hp @ 5400rpm. Naturally a 'T' on the end of the latter dramatically increases the output to 165hp @ 4800 rpm. Bob |

Interesting the outputs are near identical for the carb and injection (B230F) against the B230E at 131/133bhp (depending on book you've got, i've had two allegedly identical handbooks and different figures!) and does your book also show the B230FK which i believe is 135bhp?

When I look for parts its a 1996 2.3ti 135bhp. I also liked the B230E engine in my 240GLT. Both great with the AW70 auto gearbox. James. |

I know when Vauxhall did the Astra TD (mid 90s so Mk3 Astra) the n/asp 1.7D was ~54bhp, the LPT was ~70bhp and the HPT was ~90bhp so if Volvo had followed the same pattern, the B230F was 116bhp so i would think a better arrangement would have been 145-150bhp for the B230FK and 170-180bhp for the B230FT and would have been more in-line with what other manufacturers were doing.

Look at the early 760 Turbo intercooler. This was high horse power but not repeated. Never driven a HPT version 940 with 165bhp. Would imagine quite good. The thing I like about my LPT is no Turbo lag. Quite responsive. I'm sure if I fitted a MBC I would love it even more. Insurance probably wouldn't as a mod to declare.
