I dont mean to say you cant do it with stock injection, I just like standalone so much more. I did the FMU/AFM thing for many months. Megasquirt is the bomb next to that stuff.

I'm not sure how much I'd worry about building a motor for my first 20 year old turbo project. Any $500 motor that runs will get you 80% of the way there for 20% (or less!) of the cost.
I might suggest that there are enough things to worry about without wondering if you built your custom engine correctly.

by using pistons not meant for a specific dome shape and lowering the compression you are upsetting the squish and swirl effect of the stock setup, which is almost the soul reason for good economy and better efficiency of the engine.
I believe using the most updated engine available is always the ticket.

Well another reason I want to build an engine is because I enjoy the project... I wouldn't have near as much fun if I didn't... I'll probably use either the B35 internals or get custom built pistons to put the compression ratio at 8.5:1... or if the B35 internals with the head will put it at 9:1 then I am perfectly happy with that...
All I know is I want the best for my project... no matter how long it takes!

I'm planning on building a turbo motor consisting of a M106 bottom end and a B35 head... Knowing that the B35 has a higher compression ratio and the M106 a lower compression (unless I am missinformed, it's possible) then what would an engine with a B35 head and a M106 bottom end have for a compression ratio?
