2.5t-2.3t difference query

[Kingsford G]

Just wondering what is the difference between the 2,any difference in strength of the internals etc.I have a good lump with a good mileage so was kind of thinking if it can come in handy.Will it handle the same boost as 2.3 one using 16-18t?

[p fandango]

Volvo experimented with using a 2.5 for the original 850 T-5, but had issues with the thin cylinder walls (S60R style) which is why they went for the 2.3

[stribo]

And yet they still used it for the P2 R

& were wrong to worry about the walls being so thin between cylinders, oh hang on lol

[T5frankie]

and it aint a 2.5 its a 2.4

[deathrider311271]

the 2.5T has a slightly higher compression ratio and as stated if pushed to the limit will crack a liner, easily sorted via Tim Williams with his shim kit. Nosh got over 400bhp out of his before he split a liner.

As for mine its getting pushed to breaking point in the next couple of months too see exactly what it can handle but been advised with correct hardware and mapping it should see in excess of 300 whp approx 340bhp

good luck with that, and a shed load of torque with the bigger engine

The P2 R is a 2.5.

That's only on cars with big boost, standard cars are fine, and don't forget 2.4s split their liners with big boost too.

thatl be ford hehe

ive heard of many standard ones splitting to. ive never heard of the 2.4 splitting a linner. thing about the R is the two things that were supposed to make it better made it worse. 2.5 engine been weaker and the 4 wd being a soft. if ford hadnt of got involved the R would of been up there with scoobies and evos

[stribo]

If Ford hadn't have got involved in Volvo, they'd have gone the same way as Saab.
We have neither split liners, nor a broken AWD, therefore we have a great drivers car.

and be bankrupt

[graemewelch]

gm were to blame for saab.

My point exactly mate, and one that is conveniently forgotten by the badge snobs.

i mean in general. im not saying its not a great car. i love the R but with a bit more though it could of been bullet proof. engine is easily sorted get a 2.4 t5 lump. 4wd is a different matter. you wouldnt launch a R like you would a scooby. custom made gears from exotic materials is only answer to make it stronger

[stribo]

TBF, the AWD system was a Volvo choice, as it was already being used in the XC90, if Ford had a hand in it, they'd have used a FF Developments viscous coupling system, as they did in the Jag X-type.

[graemewelch]

haha i knew it would be volvos fault. good job they didnt get involved. we wouldnt want 3 versions of a mondeo on the road.

The 2.4 is not bullet proof, I split a liner on mine in 30 miles, and have another 2.4 block in the workshop with 2 split liners (although they have all been repaired and shimmed and are now ok)

its a lot stronger though and they dont tend to blow up in standard form

[oblark]

Which 2.4 are we talking about ? The 81mm or 83mm bore ?

[graemewelch]

im on about the the 2005 black as fitted to my s60 t5

[merc85]

tbf i thought the original question was a inquiry about the strength of the 2.5 lpt not the later hpt one

[p fandango]

i've known standard P2R's split there liners

there are 2 different 2.4 engine configurations. 2435cc which has 83mm bore (same as P2R) & 90mm stroke, or 2401cc which has 81mm bore (same as T-5) & 93mm stroke. I know which one i'm going for lol

[lance]

My 2.5 is doing fine and according to my I phone dyno app running a peak of 302 bhp and spikes of 500 nm and a genuine 161 plus mph and 156k on the clock!

What mods have u got mate?

Jetex 3 inch down pipe and sports exhaust, itg cone filter and induction system, focus RS ecu box, Custom intercooler and Hlm map. I have some posts on here under project stealth.

I`ll look up for that,cheers mate.

Your car is a P2 Lance mine is a pre me7 P1 70series.I should`ve stated it.

[lance]

Think the safe tuning limits on mine is circa 350 bhp similar to the s60 v70 r i believe some are stronger than others, not sure about the earlier 2.5s but plenty of folk back in the day fitted bigger turbos Mark from Salvo fitted a 19t to his c70 2.5 lpt with some success I can't remember if he broke it but it wouldn't have been to much of a problem if he had ;-)

I think someone did the same with a v70 2.5t with a bigger turbo too . I think that was pre me7

Really???

Well my P2R is in fact a 2521cc NOT a 2435cc. So, that cannot be factually correct!

if your'd like to read the whole conversation that i'd had we were talking about the 2.4's & you'll see i was referring to the 2 different bore sizes. One variant of the 2.4 having the 83mm bore which is exactly the same as the P2R which is what i said. The 2.5 then uses a 93mm stroke instead of the 2.4 using 90mm. Is that better for you?

Oh, sorry. I misunderstood the answer. Silly me.
