The Volvo 740T is powered by a 2.3 litre B230F-series engine boosted by a water-cooled Garrett T3 turbocharger. The SOHC, 8 valve cylinder head is nothing flash, but the air-to-air intercooler on the 740 is simply huge. It consumes the entire frontal area of the car! <div class="wpimg" style="width: 302px"><a href=" us1.webpublications.com.au/static/images...les/i22/2252_3mg.jpg ">

" border="0" alt="Click for larger image" width="302" height="198" /> This huge intercooler enables the engine run a decent amount of boost without going off the scale in charge-air temp. In contrast to the VL Turbo of the same era, the Volvo employs electronic boost control that gives up to 12.8 psi of boost. Note that full boost arrives at just 2000 rpm - this gives the Volvo its peak torque (253Nm) at an easily accessible 2800 rpm. Peak power is 115kW at 5300 rpm – nothing to rave about but more than you get in a similar capacity Mazda MX-6 turbo engine. Unfortunately – as far as we can determine – the 740 Turbo was sold as an automatic only. This dulled performance and you can expect 0 – 100 km/h performance in the 11 second region.
But let’s focus at the genuine high-performance 740 Turbo – the one that seems to have slipped beneath everyone’s radar.
In 1988, Volvo Australia introduced the head-banging 740 Turbo HP (High Performance). The sedan-only HP is identified by a rear boot lip, an air scoop along the base of the windscreen, 16 inch wheels and wider 205mm rubber. Oh, and you can also pick one by the way it launches off the line!<div class="wpimg" style="float: right; width: 302px"><a href=" us1.webpublications.com.au/static/images...les/i22/2252_4mg.jpg ">

The HP engine is identical to the regular 740 Turbo’s except the engine management is remapped to deliver more boost. Interestingly, this extra boost arrives progressively between 2000 and 4600 rpm – this relatively gentle torque delivery helps avoid massive wheel spin. Peak boost is a considerable 14.8 psi, which is held all the way to 5800 rpm. A knock sensor pulls back turbo boost when fuel octane isn’t up to the job. Peak power is eyebrow-lifting 134kW at 5400 rpm.

Released in Australia during 1986, the Volvo 740 Turbo – available as a sedan and wagon - was one of the most desirable turbo machines on the market. It made the Holden VL Turbo look like a tarted up model near the end of its life (which it was!) and it employed the next generation of engine management and turbo sophistication.In this two-part series we’ll introduce you to some absolute sleeper cars from the other side of the world – and, no, they’re not expensive.

With a standard 5 speed manual gearbox (no auto option), the 740 Turbo HP can sprint to 100 km/h in less than 8.2 seconds. That’s not hanging around for a 1350kg four cylinder. Quarter mile? A best time of 15.3 seconds has been recorded!
The big Volvo’s rear-wheel-drive chassis certainly helps in the traction department and contemporary road testers also commented on enjoyable power oversteer characteristics. Maybe you could start a Swedish drift craze?!
Factor in leather trim, power windows and mirrors, air conditioning, excellent practicality and renowned Volvo safety and this is a brick that deserves consideration. What could be a better sleeper than a Volvo?
Redbook lists the early Volvo 740 Turbo automatic starting at just AUD$2100 and the last of ‘em (sold in 1990) costs up to AUD$9600. The desirable HP model ran from only 1988 to 1989 and fetches up to AUD$7100.

Uh oh, here's a first - AutoSpeed's first Volvo feature car!
Don't think that we'll soon be heading off to the funny farm though, 'cos this isn't the sort of Volv you spend half an hour trying to pass on the outside lane. That's the last thing you'll see Rick Nosnal doing in his 1987 740 turbo. His road habits are more in the direction of chasing down WRXs and chopping them off at the knees. And, no doubt, Rex owners would find that a tough one to swallow!<div class="wpimg" style="float: right; width: 232px"><a href=" us1.webpublications.com.au/static/images...cles/i4/0449_2mg.jpg ">

This big turbocharged luxury Swede was bought by Rick back in about '91 and the intent was just to enjoy the car for its refinement and practicality. But despite having 154hp worth of factory turbocharger-induced power, it didn't have the performance that Rick felt he needed. So the first step was to fit up a boost switch that allowed up to 12 psi to hit the engine. This was fitted together with a 3 inch exhaust system using dual straight-through mufflers to make sure the engine wasn't being strangled in the process. Nothing out of the ordinary here.Don't think that we'll soon be heading off to the funny farm though, 'cos this isn't the sort of Volv you spend half an hour trying to pass on the outside lane.

Yep, the Volvo could pull a fair bit harder now - but all that was sunny suddenly turned dark and gloomy - the cylinder head decided to spit the dummy. But rather than replace it with another stockie head, Rick went for a whole new engine package comprising another new BF230 bottom end and, most importantly, a 16 valve head and intake manifold from a later model atmo Volvo. The only mod to fit the high flowing head was to make some minor timing belt pulley mods. To ensure the bottom-end's durability, a set of Argo rods and Ross (8.3-8.4:1 CR) pistons are currently included as well. After the build, the engine was also equipped with a custom fabricated exhaust manifold and big turbo - which you'll read more about later.<div class="wpimg" style="width: 104px"><a href=" us1.webpublications.com.au/static/images...cles/i4/0449_3mg.jpg ">
"We had the car come to get its engine dyno'd, have an Autronic ECU wired in and then have it all fitted into the vehicle. But once on the road, as soon as the day temperature went up it was too close to the line of detonation. And the thing was as rattly as buggery with piston slap, too.
So we decided we'd pull the head off to decompress the engine via a thicker head gasket or different pistons. But when we checked the facings of the head, they were bent. We sent it off for an inspection and the report said that the head was soft and bent, and one exhaust port had cracked". Ouch.
Adam added that he knew the engine had had some abuse too, and had already gone through a couple of head gaskets by this stage. And the only thing he could do was to have the head fixed ready for re-use - they couldn't do anything about its inherent softness.<div class="wpimg" style="float: right; width: 232px"><a href=" us1.webpublications.com.au/static/images...cles/i4/0449_4mg.jpg ">
Anyhow, Rick's engine was then fully reassembled with a copper head gasket - which actually let coolant into the engine about 2 kilometres down the road... So it was back to the standard gasket (which was 20 thou thicker than the copper one). Problem fixed.
The turbo fitted is "a dog of a thing" says Adam Allan. It's a high-flow T3/T4 with a T4 S-trim comp wheel, a RX-7 bored cover, a T31 turbine wheel and a T3 exhaust housing that may have been be machined out. It's mounted on a handmade tubular exhaust manifold, with short, approximately 1½ inch diameter runners.<div class="wpimg" style="width: 139px"><a href=" us1.webpublications.com.au/static/images...cles/i4/0449_5mg.jpg ">
"Structurally, it's not the ideal engine. It's got thin walls, a fragile bottom end, poor combustion chambers and a fairly long stroke. We also found a 15% air distribution problem at opposite ends of the engine." The individual cylinder trimming function of the programmable ECU catered for the latter.<div class="wpimg" style="float: right; width: 232px"><a href=" us1.webpublications.com.au/static/images...cles/i4/0449_6mg.jpg ">
Under normal driving conditions Rick says it's really beautiful car. He gets over 600 kilometres from a tank of PULP and it's just so easy and flexible to drive. Granted, it's a little slow off the mark, but it's got long touring legs.<div class="wpimg" style="width: 232px"><a href=" us1.webpublications.com.au/static/images...cles/i4/0449_7mg.jpg ">
