Just wondering, how are the turbos controlled in the 5-bangers? Are there any real differences between the 197hp 2.4T and the 247hp T5 engine besides the turbo boost pressure? <P>If not, can the boost be changed with a simple chip upgrade in the ECU or is there more that has to be done? How much torque can the AWD system handle? I would love to see 247hp (or more <IMG SRC="http://www.swedespeed.com/ubb/wink.gif"> ) on a stock-appearing XC wagon.<p>[This message has been edited by anony00gt (edited 12-11-2001).]

Are you saying that the whole thing is different? You mean Volvo actually spent the extra $$ to develop a whole new engine instead of just using a different amount of boost like other manufacturers (I have VW in mind) do? I figured that the block and internals would at least be the same.<P> <IMG SRC="http://www.swedespeed.com/ubb/confused.gif"><P><BR>Anyway, in that case, how much boost does the 2.4T make stock, and how much can the turbo/internals take? Also, what would be the easiest way to get more boost? Chip upgrade, electronic controller, or would the entire turbo have to be replaced?<P><BR>Of course I'm not going to do anything to my mother's car, I'm just curious as to how far you can take the XC wagon. I love the car. <IMG SRC="http://www.swedespeed.com/ubb/biggrin.gif"><P>

Yup, one is a 2.4L, while the other one is 2.3L. The engine is probably not COMPLETELY different, but NO they are not the same...too many details I'm too lazy to list, maybe Drew or George will try to explain. The same topic has been brought up before, search the site. As far as why Volvo did that, I'm sure George can answer better. I dunno..and I don't care. <IMG SRC="http://www.swedespeed.com/ubb/frown.gif"> hehehe..I'm just happy I have the T5 engine.<P>I don't know much boost and hp the LPT's engine can handle, but I can tell you this much.....even the HPT engine can't handle all that much.<P>Since you are not going to do anything to the car..probably not even worth your time worrying about it. These engines are just not built for extreme power.

Well I think the motor can handle a pretty good amount of power. Plus a T5 Turbo is damn big there is no way you need to replace it. A T5 can handle up to 45psi. Your pistons and rods sure in the hell can't. The 2.4T has 197 hp I believe. The best upgrades for the T5 are making the air flow less constricting first off, but a ECU and Boost Controller make the most dramatic change. IPD rates there ECU at an extra 47hp I believe or somewhere around there so the 236hp your already at plus 47hp plug n' play. That's 283 hp with a simple chip. Then you get a Apexi Electronic Boost Controller. Runs about $350 you can increase boost to an easy 15-18 pounds. this will probably increase performance to well over 300hp. Now all this hp is to the flywheel so getting to the tires is different. I higly suggest that if you get any sort of boost controller to go ahead and safeguard against future problems by making sure you are using good fluids and doing the other "little" stuff that means so much. Such as increasing downpipe, exhaust, retarding the timing belt and so forth......<P>

There is somewhat of a big difference between the T5 (high pressure turbo) and the 2.4T (low pressure turbo). The 2.4T will has quicker low end/low speed response because the low pressure turbo spools up faster than the high pressure turbo. The size of the Turbo and the veining make up the difference. After about 30 mph or so, the high pressure turbo is in its zone and will respond extremely well. For highway passing and high speed, the high pressure turbo is supurb.<P>The Volvo turbo engines have quite a few differences to them. The high pressure turbo engine is 2.3 liters whereas the low pressure and non-turbo engines are 2.4 liters. The high pressure turbo is 2.3 liters because it has thicker cylinder walls necessary for the more extreme temperatures and pressures. It also has forged pistons, sodium filled valves, different compression, and different ECU mapping as well.<P>If my memory is correct, the stock boost pressure for the T5 engine is 9.6 psi and the stock boost pressure for the 2.4T engine is 6.4 psi. I think that there is about a 1.8 second difference to 60 mph between the T5 and 2.4T V70 models.<P>IMHO, just adding a 'chip' to the 2.4T model would be a pretty good idea, because it will give you close to what the T5 does in terms of stock numbers. Although, trying to convert a 2.4T into a real T5 is not really possible unless you use a 2.3-liter engine block. A chip and free-flow exhaust system for the 2.4T should get you to around 235hp. <P>There is speculation though that the 03' V70 XC is going to get the 2.5 liter I5 from the XC90 that produces 210hp in stock form. This likely means that the T5 and 'R' models will be getting the 2.4 liter engine block, to make around 260hp and 300+hp respectively.<P>I hope this helps!<P>-Drew<P>

Where did you get that information? Maybe 30..if you are lucky.<P>BTW, you don't always have to use A'PEXi boost controller just because I'm using it. <IMG SRC="http://www.swedespeed.com/ubb/wink.gif"> Blitz has a new one which is pretty decent, too. It all depends on what you want to do. So far, I don't even know who dares to tap into the Motronic ECM with these boost controller and control different boost level for different gear. I'm pretty sure the Motronic will freak out on you.<P>So, before you start to suggest people to use these eletronic boost controller, maybe you want to tell them to simply play around with the wastegate a little bit.<P>No....not the way that Volvotuning guys were talking about, "Ooh...how many turns can I tweak the wastegate before the turbo blows up...duhhh..?"<P>

I have to admit I don't have much expereince tuning turbo cars, I'm a sincere believer in the "no replacement for displacement" philosophy when it comes to flat-out performance (hence the Mustang). But since domestic big-block wagons are a thing of the past <IMG SRC="http://www.swedespeed.com/ubb/frown.gif">, all thats really left for practical transportation are the import wagons (SUVs are not an option IMHO).<P><BR>Actually, I read somewhere that the internals (pistons, rods, crank) in the B230FT engine (in my 940) are capable of handling a lot of boost if a new turbocharger (i.e. a Gerrett unit) was swapped in. I plan to start putting money into this car when I'm done modifying the Stang (although that's not going to be for a long while)...I fully intend to have it running the 1/4 mile in the 13s or better eventually <IMG SRC="http://www.swedespeed.com/ubb/biggrin.gif"><P>On a side note, does Volvo even make the engines for the newer cars? I heard somewhere (this was a long time ago) that they 5-bangers were made by VW/Audi and the B230 was the last engine made in-house by Volvo. Is this true?<P>

to look at it in a simplistic view, and this is the way I tell my customers (I try not to get a customer to the point of "Information Constipation"), "Volvo uses a modular engine design in all of the series...4/5/6 cyl. Basicly if you took a loaf of bread, you can take 4 slices, you have the 40 series, 5 slices, the 60/70 series and 6 slices you have the 80 series." For some people that is enough, some like for information, then I will get more indepth. Every case is different.<P>

I didn't even know that Volvo produced a 2.3 liter LPT I5, but I am sure it is for 'tax' reasons, just as in other places.

I also received an e-mail from Sweden confirming what I knew; that the LPT 5-cyl. engine in Malaysia is the same as in the other parts of the world which is 2440cc. As you correctly wrote, the displacement for teh HPT 20-valve engine is 2319cc. I don't know about SE Asia but, typically, the universal rule for increased taxation on engines is 2000cc (2.0l). Naturally, every additional 10th of a liter will increase the amount of tax you are liable but I doubt going from 2.3l to 2.4l would make a significant difference for the person that can afford to buy a new Volvo.<P>So, I (and the person who e-mailed me and worls for Volvo AB) am not aware of a LPT Volvo engine that has a displacement of 2.3l.<P>Yannis<P>

Two facts that I know about the volvo line of engines in the 90's and into the 2000+ models is <P>a) the original 960 engine introduced in 1992 is originally a prosche design for their (then 964, that was never produced, as a 6 version of the 944). It was moved over to Audi, which shelved it, however they tried a I5 varient based on that 2.9 I6 and that is what we now know as the 2.4 I5. <P>An the major difference mechanically between the T5 and 2.4T engine is the cylinder walls are thicker on the 2.3, and the turbo is different. The rest is all tuning.<P>
