using 16r rods to stroke a 18r

does this sound about right using 16r rods with 22re pistons into an 18r block would make it 2.4L because 22re pistons are 94mm but sit abot 2mm below 18r deck hight so i heard by using 16r rods it pushes the piston back up to deck height.

if you are not turbo charging then dont use the dish down pistons that he uses use flattops to give you the comp back

i looked at using the 22r crank but foud the bearing width on either the mains or the conrods was different. thats what i noticed when looking in acl book.

i have the bearings sitting here, they are suitable for:
conrod bearings - 6r, 7r, 8r, 16r, 18r, 18rg, 20r, 21r, 22r
main bearings - 16r, 18r
so the main bearings must be the different ones, could get it machined down though, i was quoted 280 odd to fix the conrod journals for an 18rg crank but i don't know if it is cheaper for the main journals.

i wouldnt dare dream of stroking an 18R with a 22R crank, or any crank for that matter.
If you want an unrevable tractor motor, start with a 22R, dont bastardise an 18RG

oh no i would stick with the 18rg crank but i'm still iterested in trying a 2.4L 18rg turbo if it fails then i'll make use of my many spare 18rg motors, thats the fun of having a toy if it dies start again.

mmmmmmmmmm, 16R has a 73.5mm stroke, that means the piston speed at 9000rpm would equal an 18RG at 8000rpm
DOOOOOOOOOOOOOOOOOOO IT
