Question Speed sensor on gearbox vs speedo cable, turbo and head volume

If you were to fit a 6 speed to a Legacy Turbo, what would you do about the speed sensor given that the Legacy has AFAIK a cable drive speedo. What ECU input is required?

Is there room to fit a 20G around the chargecooler?

How does the head volume of the Legacy heads compare to a MY99/00 UK/STi?

UK legacy has elec speedo as far as I know.

either way, you can unscrew the whole lot from one gearbox to the other.

yes you can fit the 20g easily

headvolume is larger, not sure how much, a little, to compensate for having no real piston dish, just valve pockets

You can tell me my compression then with 0.8mm gaskets and an EJ257?

Are MY95 WRX heads less tappet(t)y than the Legacy Turbo heads?

wrx heads deffo less tappety, would use them in preference I think, with ej257 gasket and lowish boost.
