Choosing the right sized turbo for N54

[Ingeniator]

Go find me a S85 cylinder head, I have an S65 head on the bench. i'll go flow em.


We're always looking for more. we've had 3 revisions since the first head we CNC'ed. Small changes, but still- changes.
In the process of cutting up a bad head so we can really push the port limits without sacrificing a coolant passage



Nah, we'll see some more gains- for sure.




well, come get on the list then

@alex@ABRhouston what is the final port size on the intake side still stock? Are you considering enlarging it any for larger runner aftermarket intakes/plenums?

[alex@ABRhouston]

It will still be for the original gasket size.

Would be able to throw some darton sleeves on this motor? For those who are trying to push past 1000whp I think that open deck design will become a liability

The motor isn't a traditional open deck, but sleeves would probably be a good idea even for the 700whp and up guys(assuming you're trying to stay reliable long term)...enough power long enough will kill anything. Time will tell though.
