correction "b5244t5"im pretty sure my block has cracked, 185,000 miles and even if it hasn't its tired and i want to start putting more power down so im considering 1- sleeving and building my current motor, or 2- swapping a b5254t5 out of the 05+ s60 t5, as ive heard those motors can handle more power. i was wondering if anyone has done this or if its even possible or if i should just build my current motor, but i dont really want to wait for the machine shop to sleeve it and its a huge investment considering i only want to make around 350-400 wheel hp
2005 s60r b5254t5 swap?

Swap it. A B5244T5 or a B5234T3/T9 would both be suitable. There are pros and cons to each. If you go with a B5234T3/T9 you will need to use the head off of your R as the B5234T3/T9 didn't come with dual variable valve timing. There's a lot of threads of people doing this swap as it's fairly common. I'm personally going to be starting the process of swapping a B5244T5 into my VR in a few weeks.
If your block isn't cracked then just build it. For the HP goals that you have, you are better investing the $$ you would spend on an 81mm block on your R engine. The internals will easily handle 400whp.
If it is cracked, the cheaper of the two paths is getting an 81mm engine + oil pan and head swap.

Prior threads have re-sleeve and rebuild costing up to $8k.
I paid $1200 for my T5 short block with only 22k miles on the clock 10 years ago.

81mm bore builds have been successful by many many people. If you buy a 4T5 ,(idk how you would, 4T5s go for stupid money these days) make sure you pull all the rod caps and check for spun bearings. 4T5 doesn't have the magnesium coated bearings like the R and 2.3L engines have. More and more 4T5s have been found to have spun bearings. I would go ahead and swap in the mag. coated bearings.im pretty sure my block has cracked, 185,000 miles and even if it hasn't its tired and i want to start putting more power down so im considering 1- sleeving and building my current motor, or 2- swapping a b5254t5 out of the 05+ s60 t5, as ive heard those motors can handle more power. i was wondering if anyone has done this or if its even possible or if i should just build my current motor, but i dont really want to wait for the machine shop to sleeve it and its a huge investment considering i only want to make around 350-400 wheel hp
A sleeved block would be very expensive. It depends on your budget. This also has its downfalls but hey, its your money 🤷♂️.
83mm bores (R engines mostly) crack their blocks; sometimes even on the stock tune. R's don't usually blow head gaskets unless you do something stupid like overheating it, etc.
That being said, I bought my R and 3/5 sleeves were cracked. I swapped in a 2.3L B5234T3/9 utilizing the R cylinder head and R oil pan.
Whatever you choose, take a really good lookover of the engine and make sure its a solid candidate. Last thing you want is a disaster scenario where you swap in a bad engine.
