Not quite; the B230K has the Heron head with guaranteed bent valves when the timing belt goes and a different emissions set-up to any other red-block.

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.

You could always fit the wategate actuator from an HPT, apparently they look identical and you didn't know, did you!

.... and my final comment on (b)hp whether it be Suffolk Punch/Clydesdale or just your regular stallion.

Having now re-arrange all my insurances etc on the 745 and V70, I am looking forward to 1st December when I can unleash the power of the B5234T3 (240hp @ 5100 rpm) on the '98 V70 CD T5 Auto after spending a few months off the road getting it 'up to speed'. Probably a good job I will have full breakdown cover!!

I'm guessing the SE was a B200...? What size engine was the GL then?

I think "A" was used for single side-draught carburettor and "K" for single down-draught although I could be wrong....

Indeed, it has both EGR and Pulsair (secondary air injection) to reduce emissions in the absence of a catalytic converter

I believe the B230FK was made for the caravaners where they didn't want high power output but the extra torque the 3.5psi produced would help with the towing capabilities. Probably something to do with tax in other countries where it is based on hp I assume too.

Nothing a manual boost controller can't fix

Hey, stop inflating the ego of caravanners!

Joking aside, i suspect the latter part about tax etc in other countries (Italy springs to mind) where engine size and i believe power are taken into consideration is probably more like it.

Shame Volvo never made a 2.5 red block for the automotive market really...........

I recall scratching my head for a long time in 1990 trying to work out what the hell was under the bonnet as it didn't look like anything in the book!!

Bob

Wasn't just me then, with my dad's 740 (1990 facelift) that I was puzzling why it didn't match what was in the manual. It makes no reference to the B200F at all!

I sussed the LH2.4 being fitted in the end by the diagnostic socket on the n/s/f inner wing.

The B230K was available from the launch of the 740 in autumn 1984 right through to 1989 and appeared in some GL's, some GLE's and all base models (estate only). For the first 2 years, the GLE had B230K with the B230E being only available in the GLT. When the Turbo was introduced in autumn 1986, the GLT was dropped (to appear a few years later but with B234) and that point the GLE got the B230E.

Thanks for clarifying that Kev, that's how i remembered but i couldn't think of the dates.
