What is the stock turbocharger on a 2001 Volvo V70 2.4T (engine code B5244T3)? The turbo is acting up and if I need to buy a new turbo I would like to buy a larger turbo to get more power out of the engine. What is the max boost the stock drive-train can handle and where is the intercooler located?

i think your better of changing the whole engine to a turbo powered one as not possable to convert normal aspirated engines to turbo aspirated unless your a magician , sorry mate can't be done

if you remove the turbo from that car, the car will not run very well because the computer is setup to run with a turbo device, it need the air flow to force the fuel where it need to go. after removing the turbo you are going to have fuel issue, stay running, be fore you buy it go to the owner ask if they would mind if you or them disconnect the belt from the turbo charger and restart the car, see how well it runs, try and drive it, if every thing works okay, than buy the car and leave the belt off the charger.

The VW serial number is located on the front of the turbocharger

Your Volvo does not have have a problem at all. The feature is what is known as a 'turbo timer' and is an important part of most turbocharged vehicles such as yours.

Your volvo is powered by a 5 cyclinder 2.4 liter engine that is turbocharged. Which means the engine works on the principle of 'forced induction' whcih helps it make more power.

A turbo like yours has a small impellor placed in the early section of the exhaust which is then spun up by heated and expanding exhaust vapors. this power is then transferred back to a 'charger or pump that actually forces additional air into the engine resulting in the ability to burn a more powerful mixture of air to fuel. Unlike your engine which even under very aggressive driving will only sustain forces at most approachign 9 thousand rpm, a turbo charger often spins with speeds in the tens or even hundreds of thousands of revolutions per minute. because of this they depend on a steady stream of engine oil to both lubricate and saturate the very rapidly spinning parts to keep them cool.

when the engine is suddenly shut off after a long or spirited drive the oil pump also stops, this could result in overheating and damage to the turbo.

As a result of this, Volvo was one of the fisrt companies to install a 'turbo timer' mechanism in its T models which as you noticed will continue to operate the fan for a pre calculated amount of time after you shut the car off in order to properly cool down the turbo.

Again your car has no problem whatsoever, this is a good thing and a nice feature to have whcih will definably lend itself to extending the overall life of your engine over time.

The S 40 came with different size and spec engines and they were not all Turbo charged versions. The choice of engines available depends on which country you are in.

The turbocharger is driven by the engine's exhaust system and runs continuously but has minimal affect at low engine RPM. Unless the turbo has failed, you should feel the turbo effect kick in when you accelerate hard but there will be a brief lag .

If you have the turbo engine fitted to your 2002 model S40 you will have a " 1.9T " badge on the rear of your car under the S40 badge. The "T" designates Turbo. An engine designator badge without a "T" indicates it is not turbocharged.

The turbochargers on these S40 models will fail (especially if the car has done a lot of miles) so you should have your car examined if you feel the turbo is not functioning.

is this a t6? if so yes. turbocharged engines have more horsepower than naturally asprirated engines, a turbo charger works like a supercharger by forcing more air into the intake, while a super charger is usually belt driven a turbocharger is exhaust driven, it will be located in the exhaust pipe or exhaust manifold and is turned by exhaust gases passing thu with the opposite side connected to the air intake pipeing, some have the intake air piped thru a intercooler which is mounted in front of the radiator(cooler air is more horsepower)

How do you know the turbocharger doesn't work? Just because the boost gage doesn't show boost PSI doesn't mean the turbo isn't working. Junkyard or rebuilt turbos aren't cheap but they're less expensive than a new one from a dealer. Don't buy a old turbocharged Volvo they're money pits. They always break down and parts are really expensive (and hard to find on older models) and you have to find a mechanic that specializes in fixing Volvo's.

Well if the engine came with the turbo than it is essential. It will cause a critical failure at some point if it goes unfixed. Could blow up. Could seize. There is alot of things that could go wrong from this issue if it goes unresolved and none of them are good

Your car goes in "limp mode"!!!
If you scan the EDC-15P engine control unit with a VAG or KTS -BOSCH diagnosis tool you will find this:
"Fault code: P1557 - Turbo Boost pressure control exceeded"
You must try follows if you are able to do this:
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increase too much and ECU (engine control unit) go in "limp mode" = engine protection software. As a result the "limp mode" engine still running until you turn the engine off (ignition switch off) and back on when the "limp mode" is deactivated, but the fault ("Fault code: P1557 - Turbo Boost pressure control exceeded") still remain in ECU memory !!!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.
It is some work to do here, but after that you will be full satisfied! NO MORE "LIMP MODE"!!!
