CLICK lobe images to enlarge. By comparison super long duration Volvo T5 GpA racing cam revs 4, to 7, rpm. The 'A' is nice in low to medium ranges but goes dead very quickly at the top. Cams were installed in a BFT turbo engine featuring a Haltech engine computer for programable fuel and ignition curves, ignition is CDI capacitor discharge ignition.
Being quicker thru the gears is a combination of turbo boost and landing higher in the rev range between gears. Another example of quicker rev-out was an uphill section of racetrack where I now change up a gear many metres before I normally would with the VX3.Volvo 240 diesel
This cam will show your turbo engines potential! A question is : 'it has great performance on the top endbut considering its steep lobes does it idle? Low end - again I was surprised, the engine is very happy to run along on light load at 1, rpm, also 2, as well. Has Link to dyno chart with this cam in a BFT. The VX3 cam is my favourite 'Volvo' manufactured cam. It also works well in a turbo engine and having used and tuned it for 3 years in a BFT, I know it well.
This cam is featured in an old Volvo competition catalogue the 'BLUE book' being mated to the head and BFB enginebut is not a 'competition' cam. Most agree its soft down low, but has a very sweet and flexible mid range. It pulls about rpm further than other 'Volvo" cams to around 5, rpm and will continue to rev to 6, rpm, but the last rpm step is slow can depend on valve spring condition.
In a non-turbo engine, its not as exciting, better known for smooth performance and being a quantum leap over a standard 'M' cam.
The 'H' 12 mm lift really revs in a normally aspirated engine not suitable for a turbobut check ipd or ENEM offerings.
VX3 Spec - Exhaust Opens Running in - Instructions usualy advise: Do not idle the engine during the first 20 minutes of operation: run at rpm or above. Hint - place an object at near rear of exhaust pipe to baffle the exh sound so you don't annoy the neighbours. I have done several trips interstate to Sydney Australia with this cam and even in an auto it transforms it into a totally different motor.
In spots where the car previously dropped out of overdrive it now just carries on. I actually accelerate on hills where I previously ran out of puff, it pulls strongly in mid to high revs and I should have swapped out the M cam long ago. I am very happy with it. But there is a downside - unlike the M cam, the V15 cam does I found require careful valve shim adjustment plus fine adjustment after a few months and does not seem to hold its spec for ever.
I do not yet have clicking tappets on idle but on off-idle revs I hear more valvetrain noise. Normal for this cam I understand. The Camshaft ID is at the rear of camshaft at rear of engine. With valve cover off its possible to position an inspection mirror at the rear and see the markings, but if the ign distributor is mounted into the rear of the cam, you will need to remove the distributor to see. ENEM V16 revs to 6, rpm.

Not really. The end result is a cult of personality surrounding one of the iconic cars ever to come out of Sweden. The rear-wheel drive also happen to have evolved into one of the least-likely performance platforms out there, with a legion of dedicated owners providing a global support group for anyone who wants to try to squeeze at least a little speed and better handling out of these modestly-appointed automobiles. There are many paths to take on the journey from slow poke to FTD behind the wheel of a Volvo Still, there were a number of factory models available that were quicker than average, and which have become respectable starting points for would-be tuners.
If you want to keep things in the family, there are a few Volvo-sourced swaps that are for the most part plug-and-play. Forget chasing naturally-aspirated power, as you money will go a lot farther in the world of forced induction. Which engine should you target? The BFT 2. This is ayou could put it in a The stock setup was intended to prioritize comfort over cornering, and Jared also considers a set of lowering springs usually up to a 35mm dropstiffer shock absorbers, and poly bushings all around as a great starting point.
You might be tempted by chassis bracing and strut tower bars, but keep in mind that the stiffer you make the car, the less comfortable it will be on regular roads. Rear-wheel drive, solid construction, plentiful parts availability — all three of these factors add up to a community of third-party engine swaps with a history dating back to the s when Converse Engineering began selling the first Volvo s outfitted with 5. While the continues to be a common, and relatively affordable swap for the Volvo crowd, the Series is not immune to the wave of LS appreciation that has swept over the entire customization community.
Affordable starting points include 4. If you want to graduate from the world of one-wheel burnouts to a full-locking diff out back, however, then a stouter unit is recommended the 8.
Remember — these are just a few of the things you can do to a Volvo to get the juices flowing quicker than they did when your sedan, coupe, or wagon originally left the factory. The only limit to how wild you want to get with your car is typically your budget, but if you use your imagination you can usually get around any financial roadblocks with a little creative engineering.
Volvos are fun! For more of a classic perspective — along with access to race-tested engine expertise — Vintage Performance Development has been focused on the Volvo community for the past 15 years.

Note 1 : B23ET turbo came with head big coolant passage, although some are small coolant passage ; Note 2 : the B23FT for USA had a head; Note 3 : head is small coolant passage design. Due to inlet port design, the head is a desirable item for higher performance engines.
The inlet port design is significantly more advanced than the 53 0. Looking straight at the pic, notice the oval port bias is tilted to the left influencing flow to the left hand side, then it rolls toward the right as it swirls up into the combustion chamber and past the spark plug. The curve of the inlet channel as it approaches the bowl is referred to as a 'swan neck' shape is slightly up down and around.
Also see pic below. The inlet port has a rounded shape - straight-in and up with no port bias or flow enhancement. Spark plug points towards the hot exhaust valve good anti-knock design. There is quite a difference in spark plug angle between the and The sits at a much lower angle laid over more aimed more toward the exhaust port than the Combustion chamber Volume : Blue area indicates the chamber is larger around the exhaust valve than the Pink area.
Both combustion chambers measure 94 mm width across. Cylinder bore is 96 mm dia for 2. Illustration by A. Quote from Volvo - "Exhaust Valves are sodium filled and stellite coated. This provides good durability despite the high temperatures which arise in a turbo engine. The exhaust valves are tubular and partly filled with sodium. When the engine is running the sodium melts and is thrown back and forth in the valve.
In this way heat is transferred via the sodium from the valve disc to the colder valve stem.
The temperature of the valve disc is therby reduced and its durability increased. Stellite is a material which has a very high heat resisitance. Important - The exhaust valve outer face should not be modified otherwise the stellite layer will be affected and the valve's heat protection reduced. Scrapped sodium filled valves must not be mixed with normal recycling metal unless the sodium has been emptied, due to a risk of explosion when the valve melts in a furnace.
Diameters are listed under picture, Lengths much the same. The HEAD uses a large diameter valve spring The HEAD uses two different spring sizes, say small and medium. Service kit - the small low-friction springs were revised to a medium size spring and a 'service kit' developed being available from your dealer x8 req'd. The head 'service kit' contains one medium diameter spring plus the larger top and bottom retainers.Even though the has been out of production for almost 17 years, it is still a popular car among Volvo enthusiasts and a favorite among our staff.
Over the past 35 years since it was introduced, we have come to know quite a bit about the iconic model. Main Fuses Models The main fuse box is located in the driver side kick panel and sufferes from a few design flaws. First, the fuse box is susceptible to corrosion from water that can enter the interior and drip directly onto the fuses. Second, the small contact area of the European ceramic style fuses also leads to corrosion due to electrolosis. Prevent numerous problems associated with the fuse box, by pulling all fuses and cleaning them annually.
If you encounter a intermittent or no start issue on youryou can often get going again by simply spinning the fuses in their holders, which reestablishes electrical contact.
Not for use with automatic climate control. OD Relay, wiring, switch and solenoid Models Why in the world Volvo chose to use an electronic overdrive instead of a real 5 speed manual transmission is beyond us, but they did and we have all suffered that decision!
Most common problem with the overdrive is due to the shift knob accidentally being pulled off of the shift lever while trying to engage reversewhich results in the OD button wires being disconnected from the switch. Next is failure of the OD wires just below the shifter, where they simply fail from being flexed back and forth thousands of times. Last on the list are the solenoid and the overdrive themselves. The overdrive works off of hydraulic pressure and as they age, they begin to lose pressure and engagement will become unreliable.
Call for details. Be prepared to replace them every years depending on how hard you drive the car. The reason for the unusually short lifespan of these parts is due to the safety related design.
The mounts are designed to allow the engine to move back and under the car, keeping it out of the passenger compartment in the event of a serious head on collision. Volvo has had problems with this system since it was introduced in Volvo's still run into the same issues on their newer models. Possibly in theory Volvos system is better, but in reality it gets overlooked and inevitably becomes clogged up and causes oil leaks and idle problems. This hose rests on the inner fender, over time a hole will wear through where it touches.Volvo Cars has a long reputation as a maker of inline or straight engines.
This list of Volvo engines gives an overview of available internal combustion engines. InVolvo acquired a majority of the Penta stock, and inPenta became a subsidiary of Volvo. Previous owner, Ford Motor Companyallowed Volvo to continue to design their own engines, with a new-generation straight-six engine introduced in More recently the VEA program has been launched. VEA engines are branded as "Drive-E" in marketing.
InVolvo Cars announced they will no longer develop diesel engines. In Volvo changed their engine branding nomenclature so that it is independent of engine size and number of cylinders. The letter "D" designates diesel and "T" petrol. Letters are followed by a number that dictate the level of power. The table below list the lower limit power required for each emblem in It is marketed under the Drive-E and G-power names. The Volvo Engine Petrol 4 is a four-cylinder engine with 1.
The Volvo Engine Diesel 4 is a four-cylinder engine with 2. It is used by Volvo in limited markets. Volvo's first six-cylinder engine was introduced in It was a side-valve straight-six engine. Volvo's next major advance was the B4B line of compact inline-four engines introduced in The B18 of was the company's next major advance, with five main bearings. Volvo introduced the PRV engineits only V6 enginein The PRV was available in 2. Volvo licensed diesel engines from Volkswagen Group for decades.
Volvo began a line of modular engines inwith straight-fourstraight-fiveand straight-six variants.

In the last Volvo Modular engine was produced. From Wikipedia, the free encyclopedia. Wikipedia list article. Main article: Volvo Engine Architecture.
Main article: Penta DB. Main article: Volvo B4B engine. Main article: Volvo B18 engine. Main article: Volvo B30 engine. Main article: PRV engine. Main article: Volvo Redblock Engine.The Volvo B21 is a slant straight-four engine first used in the Volvo seriesmeant to replace the B The B21 and all derived engines are often referred to as red block engines for the red paint applied to the block.
The primary differences when compared to the B20 was the switch to a SOHC in place of the older pushrod configuration, and an aluminum crossflow cylinder head versus the iron head of the B Initially the overhead camshaft versions were offered as optional equipment on thebecoming standard in all markets by the model year.
The overhead camshaft motors were available in displacements of 2.
The engines are tilted approx 15 degrees to left exhaust side to make room for the more complicated injection systems.
B19 and B21 blocks can be identified by water plugs on one side of the block. The B23 blocks have them on both sides. The camshaft is driven by a toothed belt that is driven off the front of the crankshaft.
All single camshaft versions of the engine with the exception of the K series BK, BK are of 'non-interference' design, meaning that failure of the toothed belt will not result in engine damage. Also new for the model year in Canada previously introduced in outside of North America was the B23, with a displacement of 2.
Aside from the increased bore size, the engine is identical to the B Volvo used a slightly different mold for the turbo engines to cast a boss for the turbo oil return line. The IBS kit consisted of an intercoolerappropriate ducting, a new fan shroud, new oil cooler lines and mounting brackets, and optionally an automatic transmission kit. Midway through the model year, the "intercooler boost system" became standard on North American Turbos.
Let’s Talk More About Volvo Engines
Additionally a bigger clutch and a stepped flywheel were included. In a revised, "low friction" design was introduced, dubbed the B and B depending on displacement. Also introduced in were 16 valve, twin-cam variants of the B and B, dubbed the B and B respectively. The B was also available in turbo form in some markets such as Italy where large displacement motors were taxed heavily. Both were the first redblocks standard equipped with oil squirters for piston cooling.
Crankshaft, connecting rods and pistons were all forged. Exhaust valves were sodium filled for cooler operation. Other differences from the normal 16V redblock engine are that it uses a remote mounted oil filter Away from block on exhaust side engine mount and a windage tray.
For the B enginespiston cooling, oil squirting jets were added to help alleviate piston slap problems on the turbo motors.
Another modification was to go from a square toothed timing belt set up to a round toothed timing belt setup which made for quieter belt running. Although availability of the redblock was phased out in in North Americaproduction continued in Europe until when the model was discontinued. Where B stands for "bensin" gasolinestands for the displacement in decilitres, and X is an appropriate suffix. B SOHC, 2. Special version for certain European export markets e.
