I am currently in the process of swapping a Datsun A15 motor 
with 5 speed into my 65 Sprite.  The trans is the one that Mini 
Motors and Mini-Mania offer conversion kits for.  

The engine is a pushrod, non-crossflow 4 cylinder.  It is layed 
out very much like the BMC A series motor.  The overall size is 
very close to the original motor also.  In stock form a A14 is 
rated at about 70 h.p.  The nice thing is that this is a 5 main 
bearing motor with forged crank and rods and an aluminium head.  
It is also an unleaded fuel motor.  

At one time there was an SU carb setup ( Hitachi ) avaliable 
from Datsun that was used on cars in Japan and maybe Austraila.  
The large port cylinder head is still available from this motor. 
There are also Weber sidedraft setups available.  The motor was 
available in 1200, 1300, 1400 and 1500 cc versions in the Datsun 
1200, B210, 210, F10 and 310.

When the B210 was raced in IMSA these motors put out about 150hp 
at 9500 RPM with the stock crank and rods.

The transmission is almost exactly the size of the Sprite tranny 
and the shifter even comes up the same hole.

My plan include a negative ground conversion using the Datsun 
altenator and the Datsun starter. The motor also has an 
electronic ignition which I will use.  

I have corresponded with a fellow on Compuserve who has done the 
conversion and is very happy with it.

If you need any more info, just let me know.
