Yep!! There you are! And at the going price
considering the MiniMania/Hans Pedersen
kits.
More low/mid-range torque for street
fun. Having driven a stock '67 1275 Spridget
using 6psi boost, I can honestly say it is worth the 3k assuming you are go
ing to keep the car. Probably one of the most
worthwhile upgrades besides the Datsun
5 speed for those who want true "quick".
6psi is the lowest amount of "effective" boost (torque/heat) without unduly
loading
stock parts providing you don't over-rev
the motor and resist the urge to constantly
take it to the redline, bearing in mind we're
dealing with a 3 rather than 5 main bearing
crank. A Metro, Kent 256 or Cooper "s" cam
for excellent low/mid-range punch or more
radical cam if you want to "build" the motor
for the upper ranges (EN40 crank, etc).
Obviously, you want as close to the stock
bore as possible (block strength/bore flex)
and a set of Total Seal II rings in a nicely
balanced/rebuilt 1275 or 1293 with no more than 9.0-1 with alum. head
considering today's "girlyman" readily available unleaded premium pump octa
nes.
Team it with a Datsun 5 speed (using the
Datsun disc) and 3.7=3D3.55
diff. together with later, stronger axles and transfer loads with a resonab
le amount
of care and the driveline should last.
An alum. rad would be nice along with an
outside air induction source.
Pure fun!! :):)
