We've had a 4 liter for 18 months now..

Its nothing new, but it can only be made reliably (IMHO) from a very rare, very late M96 engine. Not every core has the proper material to reliably allow for a bore of the required size.

The difference is the LN/ FSI way of doing this doesn't impact the capability of the coolant to circulate around the top of the cylinder, the hottest portion of the cylinder.

About 24K will net 450HP N/A
