Are you talking about the 2.4 T5 engine ?
If it's an LPT 2.4T I don't think you'll really need to fiddle with the CR until you've got some fairly serious supporting mods?
To further what monkey said, on a purpose built turbocharged engine you shouldnt need to mess with the compression ratio, generally the only way you would do that would be to alter the pistons/bores and you wouldnt go to that extent unless you wanted to run some serious power, which on a 2.4 T5 would probably be in excess of 400bhp.
Im only generalising as i dont know a lot about T5 tuning, just turbo tuning in general but unless youre thinking of building a racing/drag car i wouldnt worry too much about CR
think its a 850 2.4lpt engine he's using
new turbo, FMIC, injectors and stage 0 (coil packs, oil, hosing, MAF, FPS, sensors etc...) should see you right.
Spend the rest on your suspension :)
You can use S60R pistons to lower the CR. Smithy did something similar with his 2.5 V70, think he got the CR lowered to around 7:1
I would have thought ultimatly, the 2.4 is the better bet seeing as it's more cc's. I dont know just a thought, althoug you hear of many well at least i dont that people have moded.
I'd have thought any volvo t5/lpt engine would need rods etc after 400 bhp
Like i say i dont really know.

Salut!
Pookie
Get a T5 block and go mental :)
You'll get to 350bhp and it'll just be a bawbag to get more with the LPT engine.
lol i know what you mean, if it was a 6 pot bmw, evo or scooby i could babble on all day about them lol, just volvo is so different and the power they can pack plenty of it, just miss the power i get from a scooby thats why im after it so much more from the volvo lol
