V70 2.3T but not a T5 -Is it possible?

[Jamest5r]

where did you hear that one mate? As i said mine is an early 94 & identicle to the pre-T-5's, including having the reverse intercooler set-up & never had an issues of it being weak

My mrs is an early '94 with original reverse i/c and came with only T5 on the back, is this original way? not had a respray and no marks from previous badges, owned for 6yrs was mine before always thought this was the way they first came. As for weaker engines this car has been rica 304 for over five years only got a k&n panel filter had no problems and she pulled 14.87 at york a couple of weeks ago.

I spoke to my mechanic (mate) who served his time with Volvo and he heard nothing about the weaker T5 unit. He fully believes they are all alike, he did say there could possibly be strengthening to the T5R but that would only be a guess.

it would of had "Volvo" on the left of the number plate & "850" just above the T-5 badge (thats how my 854 was badged, which is also an early 94). The very first T-5's were only badged as "Turbo"

i've had a quick look at some engine numbers

• 93 the 850 is only listed as having B5204FS, B5252FS & B5254FS LH3.2, no T-5 engines at all
• 94 they list B5234FT,
• 95 they list B5234FT, B5234T2 & B5234T5
• 96 they list B5234FT, B5234T2, B5234T4 & the B5234T5
• 97 is the same as 96

• B5234FT is the normal T-5 engine
• B5234T2 isn't on my list, & was also used in the ?70
• B5234T4 is the 850R (16g) engine
• B5234T5 is the T-5R & 850R auto (15g) engine

anyone any idea about the B5234T2 engine?

[volvoturboman]

No idea mate, as for the 93 not listed this could be because although you can get a 93 T5 (I had one) it was a 94 model. Mines for example was built November 93.

yeh i think your right, but as they used the B5234FT till the end indicates to me they didn't change the T-5 engine

Nice one Ped,settles that one then...........Maybe time for me to give up on the class A's.......

as i said yest mate we can only go by what we're told, i've been told (& believed) many a thing over the years.

2 more questions tho

• what is the B5234T2 engine?
• & what difference are there between the T-5 & T-5R engine, both use the 15g (would they give it a complete different engine number just because it has a different ECU?)

[volvoturboman]

Thanks for that, always helpful info in an arguement lol. As for your 2 questions I don't have a clue I wouldn't have thought a remap would mean a different engine number but then again you wouldn't know its quite possible as the two cars perform differently.

[AlanG]

Hmmmmmmmmmmmm!! Always thought the only difference was the map giving a 30second over boost. Volvo are fickle though as we know. As for t'other no clue at all.

Volvo do work in mysterous ways lol

link to engine code info, i'm not fully convinced the B525 info is right

It's just the different ECU. If you look at some later R cars auto/ man you will find a different engine code because of a different turbo. Early 850s had different piston rings to the later one if that is of any interest to you.

if i get chance tomorrow i'll go a bit more indepth & see if i can spot any changes

this is interesting about the 850R tho, different intercooler!!

The greatest feature of the new 850R is not its paintwork, but its improved performance. The 2.3-litre 5-cylinder engine has been equipped with a
larger turbocharger, new intercooler and a more sophisticated fuel pressure
sensor (to obtain an even more precise air/fuel mixture), to increase power
by 10 bhp, to 250 bhp at 5400 rpm.

Didnt Volvo do a 2.0 T5 around 210 BHP for the italian market in the 850s

[Alan M]

The intercooler in the 850r is the same type as a 70 series t5 item.

[jdavis]

p fandango - thanks for that engine code list, quite extensive.

no problem mate, as i say i think some of the bore & stroke info is incorrect

[LeeT5]

Base Model T5, was cloth seats, No headlight wipers, standard Air Con, Leccy windows all round, and Remote Locking, and double din 802 radio cassette, and that was it - similar to plod spec in regards toys

Correct! However if it was a T5 it should be sitting on 16" alloys not 15s!!

Bet you any money you like it's an LPT 2.5.

Yes. Not just for the italian market...most went to the U S of A.

[Dangerous Dave]

Here you go PF, a list of 850 engines in 1997. T2 engine shows up as Thailand only.

Also interesting is the difference between the two 850R engines for different gearboxes.

Attachment 6835

Obviously this is just for the 850, I'll try and find the other variants later

[Wombatbomb]

That would be because of the different turbochargers I would think.
