Default 2.5 CDB

Hi guys,
I'm going through the options for a new build, daily driver/track day use, so after a little info please,
I've heard good things about the cdb stroked 2.25/2.35 engines, but not much on the 2.5 cdb using top hat liners, I would prefer the extra capacity for low down torque/ spool up if possible, anyone have any previous experience witrh this type of build?
I already have an EJ20 sti cdb in good condition so would be a shame to waste it,
Cheers

ive got a 2.0CDB rebored+linered to a 2.5.

Low down torque compared to the 2.0 is immense

if i was to do it again i would go 2.33 i think for more revs but im not complaining at all

I've had a 2.0L CDB sleeved to 2.5 with top hat liners. Will cost you circa £1100.

All this crap about 2.5's not revving is just that, crap. With the right components and a big enough turbo the 2.5 Will rev to 8K no problem. There are plenty of builds on here to support that too.
