S60R engine in a 850

[oblark]

The 2.4 has a 90mm stroke and the 2.5 has a 93.2mm stroke.

3mm as i said (ok i rounded down the 0.2mm lol), but doesn't that mean its a different block

[oblark]

It's either done on the crank or the con rods.

the 3.2mm less stroke is done via the crank, but what i'm trying to say is it can't really be the same block as the piston moves 3.2mm less is it further away from the top at TDC than a S60R block. Who knows if they thickened the cylinder sleeves while they were losing the 3.2mm

bore is 83mm on the s60r and 81mm on the 2.4 IIRC.

ah just looked thru my engine list, & yes the B5244T5 has thinner bore & longer stroke

B5244S 2435 83 90
B5244S2 2435 83 90
B5244S4 2435 83 90
B5244S5 2435 83 90
B5244S5 2435 83 90
B5244T 2435 83 90
B5244T 2435 83 90
B5244T2 2435 83 90
B5244T3 2435 83 90
B5244T5 2401 81 93.2

Not sure if it is or it isn't but shorter stroke plus longer conrods COULD put the pistons at the same height at TDC. Just a thought...W

very good point, i've only ever heard of the 139mm or 147mm rods tho. Be certainly cheaper to lengthen the rods than make a different block

I have a s60 head on my new engine with the vvt deleted, solid lifters, ported and polishes and fernier adjustable camshafts on a 2.4 s60r bottom end.

So a 2.5 R block (with the right mounts) with an 850 head would go in without too much bother?

Yes

i am particularly liking the black pv544 with s60R/2.4T engine in this month's ppc magazine. took the owner 10 years to build but what a great job.

the article might give you some tips about this question.

oblark- are you sure about the 850 head onto a s60 r block? - i thought the r engine was the first on the narrower block , which is think from memory is either 40 or 20mm narrower.

The s60r block is not narrower that happened when ford wanted to put the engine in the focus and it was too wide.so they narrowed it for that car and then Volvo used it in the s40/v50 because that had a focus platform.

i stand corrected then , but the narrower block is also in the s60/v70/s80 i'm sure- its just the later version. when the s40II came out, they told us on the new model course it was done for crash zone space .
maybe its from when the 2.4t became the 2.5t 2004 / 2005 ish?

smithy - get back to your 900's lol

[cherry1809]

Hope not, lol.
Good timing on the thread starting up too... Lol.
Having dalhousie's S60R engine off him for mine, as mines well and truely cattled now. Plan is, unless anyone pops up with a spanner for my works - Shim the 2.5R block (might even stick forged rods in while it's in bits) ported 850 head. Anything I don't know about that will stop this?
I did ask Tim Williams and he said it's more hassle than it's worth.

Sounds good. Let's see who gets one together first.

I would reconsider purchasing anything from Steve. Severe lack of morals, and would do anything and screw anyone over to make a few quid it would seem. I'm just downloading my small claims court forms as we speak...

I wouldn't use the R 2.5 block anyway mate. Seems like a lot of work for no real gain, but if you want to go down that route, use the 2.4 from a late T5. In plentyful supply, and much cheaper. No need to fit liners and no need to fit forged rods either.

Ohh, that's interesting, is there a thread somewhere?
