850 T5 and V70 T5 differences..

[stribo]

Oh lol, my 850 engine is a B5234T3, it came from my (N reg 850) it was a replacement engine in that car under Volvo's warrenty as the original expired. Its now sitting in Blacky

So you've got a forged engine without even realising it.

The difference Frankie is on the plastic timing cover:

850 should read B5234T

Pre ME7 `97 V70 says B5234T3 it has all the benefits of an 850R engine plus being stronger.....Volvo in those years did not stand still in there development. The early V70 also has the 850R/T5R manifold the ordinary 225bhp T5 is different. The clutch is the same as well.

I should know as i only ever buy Volvo parts and not aftermarket ones where they may even sell three different clutches....the reason there are three it is probably "old stock" Volvo do not have old stock as they keep up with technology and also the price is about £245 which is about the best price.

You yourself may of bent rods in a V70 but i know of no other that has.......owners swop engines around from model to model just because they are 5 cylinder so if the label is not on the timing cover nobody knows what the engine is!!

most of what you say keith is good advice but other stuff just aint right, the manifolds for one are the exact same, ive broken enough and changed enough manifolds to know, and as gavin said his 850 engine is a t3 type

as you are able to stick volvo data up, put some up that tells us about these strengthened engines

Sorry merc but your not reading correctly!

If you look at the Vadis chart for 850 model you will see that even as late as 1997 an 850 T5 from Volvo did not fit the B5234T3 engine from the factory, that was for `97 V70 only.

So don`t Lol as your T3 engine must of been put in as a replacement which is also why you say in your previous post that your rods are fine on 20psi and so are mine as well because of the T3 engine. Plain 850 rods bend........period.

Err, dean has standard rods in his 850 t5 and he's been fine. Gav was talking about how good mapping helps the rods.

i think you miss understood me 960kg, My B5234t3 came from my 1996 850. (which it did) In the vehicles History it was subject to a Engine change to the B5234t3 lump at 45k. what was in there previous i dont know.

I agree decent mapping and a decent driver don`t bend rods!

[claymore]

Never bent any rods with my old 850 engine and that was running 320bhp and was heavily abused.

Sorry merc got carried away there!........The T3 is a very strong motor i have been on 25psi quite often with my HLM304map because i wanted to fit forged rods and go further with the tune but so far it`s fine and now just settle for 20/22psi

hummm dunno about forged,

I'd be very very interested!

Seems to be a lot of clashing information here too :p

Well, you've just contradicted yourself, i did quote you, here is the end of what you said.

According to Keith's info the T3 engine has forged rods, but not h beam.

lol still none the wiser

960kg,Our old 850 T5 had the B5234T3 engine fitted when it was bought new.
But it was a 97 model year.

[merc85]

Just been looking at a old volvo microfische and the part numbers for the connecting rod looks like it only changed in 2001 onwards upto then thay all had the same rod part number, 1270483

[t5 pete]

Our 1997 c70 engine t5 pre me7 had the same manifold as the 850 t5 ive heard lots of talk over the years that 850r v70r rods are stonger but still havent seen any comparison not to say they arnt but u till the proof in the pudding is actually shown its iust speculation
