so....i went to the junkyard the other day to poke around, couldn't find any maxima's but noticed that some early 80's skylines with the L24(E) have an N47 head...i think this is the same as the maxima one
is anyone running a MN47 setup?
i have an F54 block, i think with dished pistons, so i don't think that the compression would be too high
i'm running a p90 head at the moment, and the car is NA so compression is quite low....
just wondering what you guys think?

Like Ashley said I'd keep the P90.
However best results would be from changing the pistons over. The P90 flows well it's just not as easy to get a high compression ratio from as say the early E31/E88's.
I would highly recommend reading the "How to modify your Nissan & Datsun OHC Engine" By Frank Honsowetz he goes over all the heads and advantages/disadvantages of each.
I don't recall alot of info on the N47 myself. However with regard to the l24E I believe they use a different bearing set up on the crankshaft which isn't that great for higher power applications.
IMHO the best non cross flow heads for the Z are as follows in order of preference.
P90(A) (A requires change over to standard lifters).
E88 (Early 240z 70-73ish).
Of course that's the heads in standard form each can be modified and changed to be almost as good as the other it will just cost you more money.

The final drive turns in 2600 rpm at 100 kph.
