Vw ACL 2.4 turbo power increase

[3Bar]

The pistons and head are different, as well as likely the camshaft.

Why not turbocharge the ACL, and fit an air to air oil cooler? You just need the exhaust manifold and turbo from a d24t.

Thanks for the info, the ACL engine is the turbo version fitted into VW LT trucks.
The thing is that the ACL makes a lot less power compared to the D24T

I know in the TD Vanagon, VW went with a slightly lower max RPM, maybe the same applies to Transporters.
I'd almost bet on any differences being in the pump.
Your gas intake may be an upgrade.
