What engine management? I read in the other thread that you were toying with sleeving, Why didn't you?

Looks like a good build to subscribe to.

Unsure if it is a new design or not...just know that it took extra time for this to be shipped out to me due to having clearance issues with the downpipe.

I will be using Cobb Engine Mgmt. Looking in to if I can run speed density with the Cobb for this. As for sleeving it basically came down to cost. It was an additional $1200 to sleeve it so I passed. I did not come across enough proof that the was the sure way to go for preventitive measures on the newly built engine.

You will have no issue doing speed density with the Access Port. I wouldn't even piddle around with MAF based tuning on a build like this, except for break in if going e-tune. I wish I would have done some sort of reinforcement on my block, if it pops after two summers vs three I saved 50% on the build. But i didn't so who knows.
