I am about to embark on an mfi to efi conversion on my s2. I have gathered most of the bits required,but my main problem is with the bottom end and the cps.
Is it straight forward to drill a hole in my original block for the cps?
If not, will an xr2i block be ok as a base,obviously with the pistons etc. changed.
I know a frst bottom end is the answer,but i want to make the best use of what i have.
