Lots of these engines around as fitted to the Police spec T5's from that era.

thats funny cos the guy in the volvo scrapyard said that the 2.4.s were crap and much less reliable than the 2.3

But the 2.4's are more reliable than the 2.5's (I think) and therefore makes for the best compromise.

OP just some thoughts to ponder. We've been talking about this alot in the states. Due to some recent swaps of newer engines into older platforms. There was a notable one in Sweden with and 03 S60 block into and early S70 putting down over 500NM with a GT3071 and supporting mods.

Yes the 05+ R engines are the best choice but the 02+ engines are an excellent choice too. I'm putting an 02 S60T5 engine in my 95 855 in about a month along with and M56, 18t, rmani, turbotuner and other mods.

There's only a couple things you need to do to do this swap: lock the VVT hubs, machine the head slightly to accept a cap and rotor, swap over all your accessories, and get a tune are the primary things.

As I'm expecting this swap to become more common in the near future I'm planning to add some sort of hub locking mechanism to my product lineup next year after the swap.

Thanks for the above reply, I didnt think it would be a major job to do.

Is the gearbox a direct bolt on?

yes, as far as I know. You're entire (I'm presuming M56) should swap right on

The original engine in my S60R suffered from a cracked cylinder liner at 52k miles. I replaced the engine with another S60R one which had done 19k miles. I've now done another 14k miles without a problem, but I am interested in your comment that the cracked liners can be avoided by fitting a big(ger) turbo and a custom intercooler. Do you have any recommendations for these?

Thanks,

they crack the liners due to too much heat in the cylinders but if you use a bigger turbo and custom intercooler should keep the cylinders coolers .i had a 2435 with s60r conrods and pistons fitted useing a t35 hybrid turbo with no probs at all and large custon intercooler too

I have had 4 custom remaps for my C70 & out of the lot the most recent with ATM has been the most successful in terms of effecient power delivery - but as it is not entirely finished yet. Still I am makeing over 300 with just 1.0 bar boost.

The same power results were achieved with Adam's previous remap but using 1.22 bar. I am hopeful that once the map is completed we will be able to turn in 320 ish??

ATM are based in Sweden - so as you can imagine getting their guy over here to finish off has been a slow process.

I have found a beautiful C70 - fully speced coupe I found on the trader - 52 plate with only 58K on the clock - GT spec. Great starting point for tuning?? ME7 engine.

Hi Brian

Was your car standard when it split a liner ?

No, it's running some kind of map, never managed to find out which, as it's running 1.35bar.

Still running with the same map on the replacement engine so I guess it's just a matter of time ...

I still have the original engine and considering fitting Darton liners if I can find someone in the UK to supply these. No rush (yet ;) ) so I've not been looking but I'd be seriously tempted if a recommendation was made :)

If i was you i would get the map off the car asap any Volvo dealer or a indy with vida would be able to do it i have never seen a standard V70R/S60R or a RICA tuned car split a liner but have seen and heard of a very worrying amount of another brand.....

As for the liners dartons are very good but the cost of machining the block and fitting the liners is high for a good job :wiggle:

Good luck

Yep, I hear what you're saying but part of the joy of running this S60R is knowing that it's quicker than pretty much anything else on the road. I've tracked it and it's fun being quicker than Z4Ms, M3s, Carreras, Maseratis, Astons, Ferraris, (some) Scoobs, etc. Going back to standard would make it ordinary. I don't mind spending money on it. The replacement engine cost me around £2k fitted and I still have most of the original engine left. If I spent another £2k fixing the old one and having Darton liners fitted, it would still be reasonably cheap motoring. It's not costing much in depreciation so the cost of making it good is still less than buying something else that would make me smile as much :)

I think your a very brave man this is what you need along with a good quality tune :

could you rebuild the old engine using a block from a 2.5 LT B5254T2 engine? (210bhp) im not sure if there are any diffrences in the block but they are both 83 X 93.2 bore/stroke and the same cylinder displacement

Do you know of anyone in the UK who can supply Darton liners? Fit them too, if they're experienced. I have access to an excellent engineer who can do the work, but happy to go with a personal recommendation.

Thanks :)

Mmm, if it's the same bore, I expect I could have the same problem running higher power ...

My last post wasn’t very clear what I meant to say is that S60R engines are rare as rocking horse and demand a high premium second hand
The b5254t2 engine is more common and probably a lot cheaper second hand .
Out of curiosity is it financially viable or even possible to use the R engine internals/cylinder head and the block from the B5254t2 lpt engine to build a replacement R engine.
