Crack in turbo manifold norm?
Someone trying to sell me used twin turbos of his rx7 told me its normal to have a crack on the mianifold where the gasket would be placed for the downpipe. His other pair had the same crack and he said every rx7 has that is this true? My shop said a crack in the manifold can only grow and is a problem and not usable

The cast iron piece that fits between the turbos cracks and is typically not a problem. The cracks can grow to appear HUGE and still not be a problem. It usually cracks on the side that mates with the exhaust manifold that bolts to the block. The DP side doesn't crack.
I've never seen the exhaust manifold that bolts to the block crack.

DP/manifold side crack is probably associated with a bad exhaust gasket leak that was never attended too(?).
