But it will only give you 1.8 capacity as the throw on the williams crank is longer....same as the 1.9D item iirc

its for a turbo engine
i thinking of the 1.9 diesel crank or the 1.8 16v :roll:

1.9 diesel crank will give you the same throw as a williams

if you use the 1.8 crank with the shorter throw then the compression will be lower, ideal if you are turbo converting! Only thing is the squish area will be affected so might affect the performance.

Diesel crank is good and strong if not a little heavy?

diesel crank is an upgrade on the williams item as the got lighter over time...

so i,m informed.

difference in piston height is about 5mm so will be a very low compression.

the diesel crank is essentially the same but been told its lighter and slightly better design, how true that is i dunno lol!

Williams block with 16v crank and 16v pistons ??
or
Williams block with Diesel crank and Williams pistons ??

this in a turbo engine, for more or less 350hp...
any ideas ? :D

The diesels cranks ARE lighter AND have fillet rolled journals. This is fact as ive got two sat newt to me!

The internal geometry of the 2.0 is cack to put it bluntly. However, depending on your boost map, i.e. how late its coming in and how strong, will determine any infuence of this on performance. e.g. if your keeping it under 7500rpm, then the engine speed relevancy isnt there.

Personally ive never tested a high power turbo F7P back to back with an 'R...would be intresting. I would hazzard a guess that there wouldnt be alot in it..despite the lower capacity, the F7P is a good basis...a bit of extra boost will soon sort things out :twisted:

For my high output NA F7, im moving away from the standard internal geometry of the 'R, and "idealising" all aspects as best I can within practical restraints. Should be intresting...fun if nowt else!
