Re: What's the scoop with the 1989 740 16-v ??? (Mr. P)

As you can see for normal use in USA, BOTH the B230F and B230FT had more useable power over a broader range then the B234F did. Yes the B234F made HP but at unuseable levels(other then in a stick car) after you wound it up. Hense the turbo was the way to go if you wanted to go fast off the stoplight in a more common automatic car. So it killed the AUTOBAHN high strung (stick requireing)B234F in the USA. I agree a nice STICK 16V is a FAST car. But I also have to say my NA B230F AUTOMATIC can and will hold 90mph(sprints to 100) all day as well on the interstates around SC. And that is with its 114hp 136tq eng.

B230F 114hp@5400 136tq@2750
B234F 153hp@5700 150tq@4450
B230FT 160hp@5300 187tq@2900

I used to have some videos of this car, but can seem to find them at the moment. Its quite wild for a 16valve, Its not in a volvo body though

.
In europe they got a stock 16v turbo, b204ft if i remember correctly. You can also put the b234f head on a b230 block and turbo that http://********************/smile/emthup.gif . HTH.

Two friends of mine owns a 242 ´75 together, with a 16 valve turbo engine... ~590 bhp at the moment, on 95 octane. The turbo is the limit, they couldn´t go any higher than that. The engine, however, is built to take the punishment of 1000+ bhp. This winter I think they´ll fit a new bigger turbo and get it mapped for racing fuel. Hopefully that will give them some nice numbers.

 

Re: What's the scoop with the 1989 740 16-v ??? (Mr. P)

The 16v just wasn't a good 'fit' for Volvo's American customers, who at the time liked things such as low-end torque and automatic transmissions. The Turbo motor was a better match in those areas. The hydraulic lifters caused some problems, either due to unreliable performance or untrained mechanics. And then there was the whole 'interference engine' scare that kept many traditional, long-term Volvo owners away.

The Porsche rumor has been around for many years, so I'd wager there is probably some truth to it. Comparing the B234F to the B5254, it seems either not much progress was made in the ensuing years, or the B234 was ahead of its time. European markets got the turbocharged version of this car (at least in 2L form), and that was a real screamer. A few guys in the US have now built, or are building, hybrid B230FT - 16v cars. One has around 300HP at the wheels on rather low boost.

Enjoy your 16v. There are many valuable maintenance tips on the Brickboard regarding upkeep of the timing belt and the troublesome external oil pump hardware.

 

does anyone know where i can get a b234f head. i want to do some upgrading and pretty much make a real fast volvo.

 

Re: (bunja2006)

Careful if you are going for the stock B230FT turbo motor you got in your 87 760 to use a B234F head with stock plumbing. You might have to trash all you got now, and use all new or used aftermarket upgrades for a B234F eng to work in turbo trim. It is way more then just slapping on a 4 VALVE Head. Research before you just buy the head and expect it to bolt on.

 

Re: (Nato740)

yes, i know i'll have to look into it and read up on i was wondering if it's possible to buy one if would want to attempt a swap.

 

also by looking at the picture above all the hose run identical to mine.i mean it look like the same exact settup almost. but there are always complecations and i'm prepared to deal with them

 

Re: (bunja2006)

Sorry to break the news to ya. If the pic up above is the same or ALMOST to your 760 turbo eng bay? Then you have one or more of three MAJOR problems going on.
1) you bought a 87 740 16V with a 760 turbo badge stuck to it by some YOYO. Hense NO TURBO.
2)you have the only 760 turbo made with NO intercooler or intake hoses for it.
3)airbox is on wrong side of car to even work with a stock turbo setup. And the Turbo airbox says TURBO on it.

The 86 760 Turbo intercooled eng bay on my moms car looked nothing like this. It had way more hoses(for the working intercooler). One more thing if your car takes the standard every other 700 seris airfilter size and not the special only for turbo cars size filter then it is NOT a turbo car.

Re: (Nato740)

yeah the air box is on the passenger side running to the intercooler and around and all that good stuff but i mean the only difference looks to be the intake, intercooler, intercooler hose, head and belt cover from what i can tell in the picture its hard to say that mine is deffinitely the same from a picture

 

whoops i mean it runs from the airbox to the turbo to the intercooler

 

Re: (bunja2006)

Ok thought as much. Not even close to the same.

 

Re: (bunja2006)

You can find 16V heads in junkyards, on ebay, boat salvage yards, etc...

Like Nato740 said, it's not just a 'slap it on & go' proposition. Some points to think about:

The 16V heads require pistons with valve reliefs machined in them.

The power made by even a 5psi boosted 16V car is beyond support by the stock fuel system.

You need to lay out some $$ for a Euro-only 204GT exhaust manifold, or have a custom header welded up.

 

ok thanks for the info that'll be something to think about and read up on and maybe attempt someday

 

Re: (bunja2006)

I've got a complete 16v B234F head for sale for anyone that's interested. No bent valves. About 180k miles showing on the odometer of the donor car. Head, cams, cam gears, valve cover, head bolts (different from 8v engines), and misc. pulleys and hardware that goes on the head.

$250 + shipping (I'm in VA)

towerymt AT yahoo.com

 

The 16V motor will self destruct if the timing belt breaks, or the idler breaks, etc.

It also rarely came with a stick.

The 8V redblock is abuser friendly and the turbo setup is simple & reliable and puts of the same hp. Adjust the wastegate and you are getting a lot more power.

So the old timers/cheap skates don't like the 16V since it's less reliable. The performance crowd likes the turbo.

So the 16V doesn't have a huge following.

 

Re: (ADent)

Keep in mind, the link i posted to the hilmersson racing websites 16 valve car. Obviously, its not a volvo body. Also, that motor is twin charged ( turbocharged as well as supercharged). I posted it as an example of what is possible on the extreme end of the spectrum.
