4.6 on Range Rover P38 - Which head cylinders

Thats similar to a megasquirt (may even be MS based)

But just because it can control a rover v8, it doesn't mean it can keep the BECM and TCU happy. Lots and lots of people have all looked at this problem and have usually sold the range rover in question before ever getting the conversion done. (myself included - but I'm still hankering for another P38 with a bit more power in it..)

Looks like i should buy a RHD Overfinch P38 and reverse engineering.

According to my Real Steel invoice my Merlins are 31cc. I had a choise in even smaller chambers but they calculated these where better for my blown aplication.
Merlin 31cc + composite gasked = 9.02:1cr on a 3.5 according to their calculation ( still have all the paperwork..).
Have to say I have a set of the first batch, I was even one of the first who bought them so I am not shure if there still is a choise in chamber cc's

Id say...Merlins all the way. Best investmend I did so far.

Just bought another 4.6 P38 - so this idea may yet resurect.
