Ok, a couple of questions regarding my 16v head motor.
I have a complete b234 and it is already completely broken down. The head is at the shop already rebuilt. Now I got to decide on the block.
Is there any reason I shouldnt use the b234 block? I think dick prince mentioned they can have uneven cyl wall thickness. I am also planning on cheapskating it and reusing the b234 oil pump.
The pros i see of using the b234 block is that I dont need to source/fab a timing belt tensioner. It doesnt have an aux shaft to run the oil pump so there is less drag there.
Some of the cons: potentially weaker block (but i think a rod will bend/break first), gotta use b234 crossmember, and i got to thread some of the oil holes and plug other for turbo oil lines. No aux balance shafts for me.
Also, what will my cr be if I use turbo pistons with reliefs on that head? The combustion chamber is obviously different. Will the CR be increased with the b234 head?
I might go with a b230ft block, but then i gotta deal with custom tensioner and maybe a custom belt too. What are my options there? (regarding tensioners and belts) All i know of is the ovlov.net tensioner and I heard something about a mazda tensioner being fitted.
