Love reading this thread but unfortunately for me would be lottery win stuff to be spending 6k upwards on performance tuning!
Just a couple of things ...can’t find any pistons listed on CP,s own site, do Carpenters have them commissioned?
Turbo’s bores look really fresh at 10k or so when the kit was installed would the liners need to be honed on a higher mileage Rocket,presuming + size pistons aren’t an option here?
. Anyone in the Uk had any head work done locally,must be someone capable of porting the head? Can’t be Rocket science? (Couldn’t help that sorry)
