I wished it was mine :)))
However I kept this pic when I was interested in doing a twin cam head.

Now Im actually doing a ca18de bottom end and worked 8v head with boost.
In the Uk and US 250hpatw has been achieved with stock ca18et with stock
8v head, t28bb and has good all round response.

So I will need to use the drain hole in the yellow outline to use as the
turbo water feed as there problably isnt one avail in the DE block?

Im also looking into not using the girdle to save weight but will need
someone to modify my bolts or have custom ones made and for the sake of
an extra 3-4 kilo saving probably not worth it. Yet love to do it as the
block is so much stronger than an A series with all the webbing and both
blocks have no skirt, yet the A series has made 320hp atw in the Yatalla 1200.
