Iv picked up a new DA6 rolling shell in mint condition, missing a engine and one mount.
Im thinking about a

b20b with new rings,cambelt,water pump,oil pump and slight head work. double valve springs and pnp.

Then throwing on a SC12 from a mr2 and running about 8psi.

And evo 3 injectors.

Im a bit confused about the sleeves on the b20b tho. Every where people say they are thinner but by my measurements that are slightly thicker then then b18b block spare Iv got.

The tunning part I can take care of.

Would cam gears be a good idea to get?
How much does a da6 fuel pump flow?

Anything else im over looking, Parts are quite cheap here.

b20b full running engine. $150
DA6 shell. $100
SC12. $200
