Cute pooch - have to admit mine is mainly for hound transport but if i give it a few beans she gets up and starts looking round to see what she can growl and bark at seeing as the car is growling!



Butter wouldn't melt of course!

The sticky label is correct including engine number .

so you have neither the High Pressure turbo B230GT 170 bhp 265 nm torque)

nor the low pressure turbo B230FK ( 135 bhp 230 nm )

Someone above asked why they bothered with the B230Fk which produces only 3 bhp more power than the non turbo B230E,
It was to keep competitive with the competitors engines and torque at the time , you would never know it was a turbo , low boost , no turbo badging and no turbo gauge .. It was all just to get an extra 40 nm of torque , it made the difference ...

Sorry but I'm lost here ? I thought the B230fk on my sticker means it is the 135bhp LPT

Also when i put that vin number in it also shows B230FK Low pressure turbo ?

Has You Dash Got The TURBO BOOST INDICATOR ? IF SO ITS A HPT MODEL BUT AS YOU SAID B230FK IS LPT WITH NO TURBO BOOST INDICATOR ON THE DASH

Regards Maria

Not necessarily. The Exxon Valdez is an LPT but has the boost gauge fitted.

It was me that asked, although my question was really why Volvo bothered with LPT cars when for zero extra cost they could have produced full fat HPT cars. I suspect LairdScooby hit the nail on the head RE European tax advantages or possible insurance costs....?

Either way, easily changed If one ups the boost to HPT levels using a MBC.

Another quick question, if the boost on LPT cars is upped to HPT turbo levels using a manual boost control how does that effect the driving characteristics? Will they perform and drive in exactly the same way as a B230FT? Does boost happen later in the rev range etc?

TIA

I don't know for sure Joe as i've never fitted and used an MBC but on the basis that thr turbo and everything else is the same, it should spool up just as quickly as the HPT and build boost at the same rate, just more of it after you pass the point where the LPT levels out on the boost and just maintains it at 7psi or whatever the low boost level is. I think the higher boost is 10psi so where it would have previously got to a certain point and no more boost, it will keep adding boost.

Someone with a turbo model that has fitted an MBC should be along soon to either confirm or refute that idea and hopefully explain it better.

The LPT was not for tax purposes in Europe that I know of as where engine size was an issue it was cc that the tax was based on. That is where the 200bhp B204 engines came from.


If anything the LPT would be more a US market thing so making it more of a lazy torque engine with all the power low down making it feel like a bigger engine.

The main thing is those engines will have lived a less stressed life so ideal for a MBC to make some extra power higher up. Couple that with a cam upgrade you can make it into a somewhat more fun car

The turbocharger on the B230Fk low boost is different to the B230Ft/Gt higher boost engines

I'm confused too! volvo have your engine listed as a B230FTs so it seems they input it incorrectly when the car was new , so you do have the B230FK it seems as per the label .
The turbo is a different ( smaller ) one on the B230Fk to the B230Ft and GT as the only reason for the B230Fk was 40 nm more torque at the lower end of the rpm scale .It was marketing not a legal or tax thing

That's strange. On the delivery documents ( from the dealer Strathmore )it has LPT and as you say the plate confirms that as well.

Should I contact my Volvo dealer with a pic of the plate ?

Really?

I'm pretty sure the B230FT as of 1990 onwards got the same TD04 (TD04-13c on later models) turbo fitted to the B230FK, only with a different actuator...
