Hello Paul and group,
Well I have now got this little baby home and out of the crate.
As my first inspection it has proved to be everything that I expected.
The Renesis engine has all the features that i have been trying to
achieve with my turbo 13B.
As the attached photos engine with oil and everything that is needed
except intake, throttle body and exhaust manifolds.
This engine is 95 kgs or 209 lbs.
I will list what I see as an advantage and no extra cost to make.

1# The sump is only 45mm or 1.77" deep and is made from pressed steel.
It is half the thickness of the old version and I don't believe you
could make it any lighter fabricating it in aluminium.
It has the low oil sensor mount.
The 44mm depth gives more room for the radiator.

2# Front housing has the water pump inserted which is lower and
will allow more head on the pump for tight installations.
All the drive belts are multiple groove and will withstand higher rpm
with reliability.
The water pump outlets are on the side and much lower on the engine
which will make the cooling system much easier to plumb.
Note photo P1010060 with temp probe.

3# Note the heavy fly wheel which is in the 95 kgs.
This could be lightened of but note a great deal I suspect as Mazda
have done a good job here also with all the weight at the perimeter.
I will measure this in the next few day and draw it up to see if it
can be improved.

4# Besides all the improvements that Paul has already mentioned about
the cooler exhaust, Fuel efficiency and exhaust emission. There is
more to be seen with time and I think we will look at this engine with
savings that will take place in using the stock engine without
reinventing.
