There is no difference internally between the 3.8 liter SFI Grand National engine and the GNX engine. Initially, there were plans to perform standard performance tricks like blueprint the motor assembly, but tests proved that wasn't necessary to achieve the goal.
For example, a port/polish job was considered. This would require a tear-down of a brand new engine, because Grand Nationals were delivered whole to ASC for the conversion. From start to finish, the process of removing the upper half of the engine and performing the machine work could easily be 50 hours of labor. Only to reassemble it and risk premature failure due to any error or defect in the process. Not to mention the cost.
It would be impractical to perform such precision modifications to 547 cars post-production in a short time frame. So, McLaren specified these external improvements: |
There is no point trying to convince most people on this forum that anything domestic can possibly come close to anything German. I get your point though; the 3.8 turbo would be an interesting swap choice.
