What Cylinder Head To Use For Best Performance With 2.3L Block?

It might be buried in VADIS somewhere, I'll have a look for the info later.

Edit, this was printed out for my '02 B5234T3, so I'm not sure what years this applies to, but it seems that the 2.5L engine uses the same intake cam 2.4L T2, which is the LPT engine, correct? It is different from the 2.3L HPT, despite being the same specified lift, probably due to the addition of VVT. No idea on duration figures.. :(

			   Intake 		   Exhaust	

Engine			Lift	PN		Lift	PN

B5204Tx (excl T4)	8.40	9207943		9.05	9207944

B5204T4			8.15	9207941		

B5234Tx			8.40	9207943		9.05	9207944

B5244Tx (excl T2&3)	8.40	9207942		9.05	9207944

B5244T2			8.40	9497231

B5244T3			8.45	9497823		9.05	9497822

B5254Tx			8.40	9207942		9.05	9207944	

edit 2, fixed a mistake in the table.

Those PN's for B5254 are incorrect - I listed the #'s above

Interesting, they are different. '02 is before the 2.5L R engine, but I would imagine they updated the document on VADIS accordingly when it was released. I wonder if the PNs have been updated since then. :unsure:

Edit: aha, that document doesn't include the B5254T4 in it's "B5254Tx" classification, since it was made before the engine existed. I agree with your part numbers, but as you mentioned, can't find the lift of the cams.

I started a thread on TB - they may know of a Swedish forum that would have such info - can't find anything in a regular internet search at all..

The only ones I have been able to turn up so far are the ones we know, the NA and turbo cams for the old whiteblocks, no VVT:

NA

Intake cam: 250º, 8.45 mm

Exhaust cam: 252.6º, 8.45 mm

Turbo

Intake cam: 242º, 7.90 mm

Exhaust cam: 243.5º, 7.90 mm

I really want to see how the addition of VVT changes those numbers. We know volvo decided they could get away with more lift, I wouldn't be surprised if they also added a bit of duration as well, since they aren't as constrained by the amount of overlap set into the cams.

If nothing turns up, I'll get the machine shop to measure them, at least we'll know what the dual VVT lift will be.

He's going to look at the valves & see if there's any point to adding any backcut on the valve itself, in addition to the normal 3 angle seat.

And I can measure mine as well. I might have the inspection equipment at work to find out what we need to know. Robbie should be sending me a 2005 LPT dual VVT head, and we can see if that's any different as well..

NicE!!!! No clue how many miles are on the one I'm getting, does Robbie know history on this one?

That table still needs an edit - the B5254T2 has a different intake #

Here are the cam specifications from VIDA 2010A. They are the same as on my VADIS 2005A. I think the other table was wrong for the B5254T2 intake cam. If I were you, I'd search for the B5244T3 intake cam, it has 8.45 mm lift, vs 8.40mm lift for the other cams.

And if you really want to know what engine is in which car, so that you can figure out the VIN numbers, the horsepower, etc, here is a table I created from spending too many hours in VADIS and online to volvo (use:

http://apps.volvocars.us/ownersdocs/2001/2001_VIN-VIC/vin2001.html

and

http://apps.volvocars.us/ownersdocs/2001/2001_VIN-VIC/vic2001.html

but change the year in the url to get information about most years. I don't think I've posted this before, but if I have, you can let me know and I'll delete this table.

Here are the cam specifications from VIDA 2010A. They are the same as on my VADIS 2005A. I think the other table was wrong for the B5254T2 intake cam. If I were you, I'd search for the B5244T3 intake cam, it has 8.45 mm lift, vs 8.40mm lift for the other cams.

Volvo_03_cams.jpg

Thanks. I don't have the vin or the motor # that the head came from, though :(

Those cam numbers are not what's listed in VADIS for the B5254T2 & The B5244T5. Based on the PN's, that's only up to 2001! (02 has a different exhaust cam)

I listed them above That chart needs editing!

8642712 exhaust, (all 05-)

3063410 intake for dual VVT R & T5

8670354 intake for dual VVT B5254T2

So we still don't know the specs on these.

VVT NA cam won't work in place of Non-VVT turbo intake cam.

Aaron's hub is simply to delete the VVT.

I was under the impression that I could add the NA VVT cam but would have to use a hub adaptor (VVT delete) since I don't have it on the intake. Are you saying I can't use this cam in my head? Would I need a dual VVT head? I know the passages for the solenoid aren't there but I figure that the cam would still fit.

Take a look at Johann's Cam Comparison pic the cams are physically different. Captain Bondo made adaptors to fit Non-VVT cams in a VVT head, but a VVT (intake) cam in a non-VVT (intake) head won't work as I understand it.

That's one reason I'm getting a dual VVT head.

EDIT - Cams will work - see later posts :D

Well, I'm not sure if it would work actually. The machining in the head is different; they added grooves for fluid control on the VVT cam, but the diameter and depth didn't change. The distance from the larger hub where the cam seal sits to the first "lip" on the cam is the same, 0.992", the diameter of that hub is 1.774", and if you line up the back edge of the hub, the gears sit along the same plane. The apparent difference there is most likely from the smaller gear mounting area on the VVT cam, since the VVT gear takes up a lot more room. They may be interchangeable if you take out the c-clips that isolate the two "chambers" of the VVT gear. I guess I can always throw the cams back in my broken head, backwards, and see if things line up and spin freely. :ph34r:

I did that this morning after reading NEU's post. It looks like from what I could see (only looked briefly) that you could actually use a vvt intake cam in a head that originally came with vvt only on the exhaust. I put the cams in backwards (int. cam on exh side and exh cam on int. side) and they both spun free. Definitely would need a vvt hub or delete hub to go on the intake cam though.

Don't even think you would need to remove the c-clips on the cam. If you look at your picture the c-clip doesn't go into the grooves in the head, it rides on the head itself. Appears to do that fine when swapped. Again I only looked briefly.

You're right, they do not go into the grooves. I was thinking in terms of reduced wear and drag by getting them out of there, although it's not a true bearing surface, and the drag is pretty trivial compared to the force needed to overcome the spring pressure.

That's an interesting find, this whole thing I was thinking that they were not interchangeable. So really, it's more a matter of RN cams cannot be used in an N head, or vice versa. The RN cams are interchangeable, regardless of VVT or non-VVT, as long as you don't want to use the VVT functionality. :ph34r:

Boy I glad I asked.smile.gif I was thinking it would be strange if Volvo cast 3 different heads for the different VVT combos.

So my next question, could you run the NA VVT cam without use the hub delete? Is there really a need for it? I've run my VVT solenoid disconnected and the car ran fine (hub didn't need to be "locked").
