Port matching

I have ported stock turbo to stock downpipe problem is the block is still on the bench awaiting pistons . Back here in South Africa it takes a little longer and not much info . My hopes are it will be a lot more responsive.

While you are porting the stock turbo, grind a hole in it so you are forced to get a real turbo

The biggest mismatch is at the exhaust manifold to the turbine housing. Look on the exhaust manifold/turbo mount and you will see.
