Can you bore a 1600 up to 1800cc ?

My brother and me want to bore a normal 1600 to 1800cc.

He wants to use an old 1600 block cause it's smaller then the 1800 block.

He/we expect it will drive better in a corsa then the 16V he drives now.
Less top speed but better cornering. (he drives slaloms)

He has a brand new 1800 block out of a total crashed saffiera that had run about 40 miles.

The main bearings have the same part number so we only have to get it bored.

Only question is what about the hight of the piston?
The 1800 crankshaft is said to have a bigger stroke and we haven't checked the numbers of the rods......the pistons are different too (most likely, not checked).

I'm willing to bet that some one has already done a project like this and I'd like all the info we can get.

We assume that with a slightly wilder cam and maybe a little work on the head it could come to an output of max 140 bhp, maybe 150 with the extra headwork?

Dont think it's possible. Cylinder walls etc would be close together,
risk of blowing headgskets etc.. Not worth it IMO.
For relability think the most you can go would be to 1700cc
as SBD have done with their car.
After that to get 1800cc probably have to "stroke" it aswell.

Continuing this thred from a few years ago.

Can the pistons of the latest small block 1800's be used in the c16se engines?
If so what is the final cc assuming that the the 1600 crank remains standard and is not stroked.
Will the MAP sensor/standard ecu cope?

x18xe1/z18xe(r) is small block and is the same as the 1600s
c18xe/x18xe(v) is big block

and the answer is no, you'd have to stroke it too, the makimum bore size on the smallblocks is aound 81mm

bore is 80.5mm / 8.05cm
bore cross section is 5089mm^2 / 50.89cm^2
stroke of 1600 engines is 79.5mm / 7.95cm I think

therefore total capacity is 404x4 = 1618cm^3

not really worth it.
