Petrified of cracking a liner.... But want to boost the thing (R)!

[jellison]

The more I read about the V70R/S60R engine the more it sounds like and accident just waiting to happen (even in bone stock form)!

From discussing this a fair bit now, it seem the 2.5 R blocks open liner design combined with much thinner liner (just for 1-200cc), makes them stupidly fragile. T5 blocks can have big boost thrown at them no problem due to beefy liners).

Now I have found this out, I am not best pleased. I know a lot on here have engines with good power increases, but not sure I really want to do this now (unless I get the block shimmed).

Clearly (for an everyday road car I am not going to be doing this) -> The full Monty! https://re-volvparts.com/store/home/...s60r-v70r.html

What are you guys views. I do want to keep this car a long time, but only if it is reliable (could crack a liner as standard is Nuts!). And preferably with a bit more power. My R feels faster low down (2.5k-3k) than my mapped T5 (some of that is the 4wd though) but from 4 and up it is definitely slower (more weight and a tad less ultimate power).

What is the answer? This Tim Williams chap gets talked about well in many places, but finding contact details hard! Then you have the Dreamscience option (looks the same to me but one person on first thread seems to think different) - have dropped them an enquiry as to whether they do on Volvo's.

Based on all this I am not sure I have the confidence in the car to get a remap (as per my old T5). But I'd like more power.........................
