Unfortunately listing as a 'Turbo' is not a good guide as many non-"Turbo" models (LPT) are still listed as Turbo in ads.

Also IMO there is absolutely no benefit in an LPT. It is exactly the same as an HPT, the pressure and power is just limited to a lower level. No benefit in lag, mid range etc. The HPT just goes to 11.
Except I think the reason for the LPT was mainly longevity, less wear and tear. Not calling it a turbo may also have insurance benefits.
The reason is purely marketing to make the 2.3 as responsive as other manufacturers 2.3 engines coming onto the market , i did mention this earlier . Other countries may do it differently of course . There are tax reasons too . and you are probably right about lower insurance .

Are you sure it came from factory like that or that is isn't actually an HPT? Have you measured the boost?

Its certainly possible they did parts bin specials towards the end to use up stock, but the point of the LPT seems to have been to hide that it was a turbo.

Check against the VIN.

If you are modifying it then it won't matter which one you get as the turbo is useless for big power, they start blowing hot about 12psi.

The vast majority of them seem to be LPT ones so just get a decent looked after one and you will be fine.
100% this. My car has done 185k, but I'd have it any day over a 100k car. Why? The history file is massive, the previous owners really looked after it (£10k spend in 5 years on it before I got it!!!) and its had so much stuff replaced on it its better than a 100k car whose turbo might go pop due to all the short journeys its been doing (5k max per year on the youngest 940's now), plus the engine wear on short journeys etc etc. Mines had all the suspension, ignition, air con, turbo, rad, etc etc etc replaced so it runs very sweetly. No real evidence of the mileage, even the seats only have a tiny amount of wear on them.

Oh and mines a HPT..............

Which engine had the thicker 13mm con rods rather than 9mm?

I thought the late LPT had thicker rods? Which had piston oil squirters?

My LPT runs well and has just over 200k

Thinking of adding an MBC at next insurance renewal in April next year.

James.

Default IS it an LPT?

I've just checked the last MoT certificate: the VIN is "YV1945861...". It's badged as a "Classic" and there is definitely no boost adjuster on the turbo so it could well be a "parts-bin special". I haven't measured the boost but it doesn't seem any livelier than my (normally-aspirated) 240GLT.

When I bought it the insurance company didn't know what engine it had and therefore which insurance group it sat in but agreed that the "Classic" badging suggested an LPT. If it is in fact an HPT then I'm going to have to get the insurance cover changed.

Going by the green book your car is an HPT

How is this thread so long and full of incorrect info!?!?

LPT 3.5psi (I measured mine so I know this is a fact)
Uses a different wastegate actuator which limits it, the actual turbo is physically the same.

HPT 7psi (not 11psi that is the turbo + kit which is around 11/12psi).

Yes LPT will be advertised as a turbo car, this isn't incorrect it still has a flippin turbo!!!

The 13C is ****e for anything over 12psi and in fact I would be reluctant to even take it to that!

The fact that a car is a LPT doesn't mean a seller is lying or wrong advertising it as a turbo as it is still a turbo.

Can we put this to bed now?

Just what I didn't want to read...

Now to try to sort things out with the insurers. This could be interesting (and expensive).
