Here is some results :
The ” Evolution ” parts are finished and the Maxi Micra has gone through lots of more Dynapack action.
But let us forst see what I have achieved so far in this project :
Started out with the Maxi pumping out these stock numbers :
51, 1 Hp @ 5370 rpm ( @ hubs )
79,4 Nm @ 2850 rpm ( @flywheel ))
Then i made a spacer , some modification to a stock ex-manifold and some grinding in the throttle body.
That gave me these results :
60,9 Hp @ 5737 rpm ( @ hubs )
98.1 Nm @ 3559 rpm ( @ flywheel )
Result :
+9,8 hp from original
+18,7 Nm from original
Percentage increase in Hp = 19 %
Then i made som adjustable camsgears ans fiddling with some ignition timing
68,7 Hp @ 6400 rpm ( @ hubs )
99,6 Nm@ 3465 rpm (@ flywheel )
Result:
+ 17,7 Hp from original
+ 20.2 Nm from original
Percentage increas Hp = 34 %
All this without bying / installing a single high performance part from the shelf.
SO NOW THE LAST RESULTS :
My cams , pistons , inlet ,cylinderhead , all DIY modified + the old ex-manifold is to be tested to find out if they contributed with some more positive results.
These are the parts that I have modified / worked with :
Here is the results , for now , in Hp and you can see the original power graph as well
and for Nm with a original for compare.
( if anyones wonder why the pulsation in Nm graph,,,,well thats what you get using a stock engine management and that’s fine for me as I am going to install a modified version of the old ECU soon and fix things up a bit in that matter. )
So then i have ( for the time being ) :
87,54 Hp @ 6700 rpm ( @ hubs ]
94,8 Nm @ 4000 rpm ( @ flywheel )
RESULT :
+36,4 Hp from original
+15,4 Nm from original
Percentage increase in Hp = 71 %
71 % percent in power output using ONLY OEM Nissan parts !!!!
( could add that i managed to squezee out 90,2 Hp @ hubs going to the far wild end of the camgear position hunting down more power in upper region but not to usable for a daily driven car so i setteled for 87,4 in the end as a compromize that i could live with )
The Maxi Micra has now rolled on the street for soon to come 6 weeks , covered more than 1500 km as shown with the “ Evo “ setup.
It works perfect in city driving , rides fine on longer trips ( 500 km t/rt )and is willing to rev 8500 rpm+ anytime of the day.
Nothing has broken down , no wear on camshafts , its start just as fine in minus 10 dgr C as when warm and almost to good to be true has even now quite good mileage.
Needs 98 octane fuel though but that is available straight from the pumps here so no problemas.
Here is a clip showing the new potensial on a 0-100 km / h ( actual 0-102,7 km /h )

Maxi Micraen has now cut in half the time it used as a stock car on this test.
But the Maxi Micra doesn’t stop here , there is more to come and the numbers on the graph is lalready reaching new peaks.
