As said in the tite, whats the gap between the cylinder bores in the block of the 1.4tsi? Dont expect anyone knows?

Gap between cylinder

Coolant passages. Car has a dual circuit cooling system.
That is if we're on the same page.
Afraid you'll not know until you tear it down and the builder/machine shop gets it.
They'll be best placed to say if it's acceptable...
Actually the second picture is not a block it's a cylinder head.
The issue with the block is not the distance between cylinder centres it is the wall thickness between the cylinder bore and the water passages. You won't find that dimension at all easy to find.

More cc = more torque? exactly what you don't want with the 7sp DSG?
APR have overcome the false limit of the box and even with a hybrid and bored to 1.5 I still cant see there being problems with torque. APR's hybrid 1.4tsi with 250-60 real hp(not amd power) the box is fine. Torque can be reduced if needs be by intelligent mapping.
Yeah true, but I put it in because the gasket was covering the block on the other pic so it wasnt posible to see the gap.
and why is it not the distance between cylinder centres? Surely the coolant under a preassurised system will support thwalls of the cylinder from its internal forces???
How does the head and stuff look? Is it very clogged up with blackshit? and how many miles did you do?
no this isnt mine, this block is off a polo gti which had done 16k miles. See overfueling cylinder 1 and lean on cylinder 4. It was a engine taken out due to oil consumption.
Dread to think what mines like after 50k

Heavens no. The cooling system runs at perhaps 15 psi (just look at the rubber hoses which can withstand the pressure), while the pressure in the cylinders of a blown engine can be over 200 psi.
The cooling system is only pressurised so that it can run at an elevated temperature without boiling.
okay, didnt realise it was as much as 200psi, i was thinking of the boost psi entering the engine rather than the boost which is then further preassurised.
This is why i started this thread because my knowladge of engine block theory is limited.
But still i ask the question if the thickness of the wall between cylinders is not the problem and the distance between the cylinder and coolant shaft/hole is the problem, haow is it if the thickness from cylinder to cylinder is less than gap between cylinder and coolant duct?
If its been done before with the exact same pistons, I should be ok surely?
After some calculations and image analysis, I believe the cylinder wall to be 5.9mm, post bore and 7.9mm pre???
